4. seT  blenD WIDTh: On one projector, increase the  Blend Width for an overlapping edge 
(for  example,  if  the  projector’s  image  is  on  left,  its  right  edge  overlaps  the  adjacent  image 
— adjust  Right Blend Width). Use the same setting on the second projector for this shared 
edge.
5.  Re-adjust  width  (both  projectors)  until  the  overly  bright  band  at  the  midpoint  of  the 
overlapping blends disappears or just changes to very light gray. For the shared edge, use 
the same  Blend Width setting on each projector. If the “best blend” appears to be between 
two settings, choose the wider setting for both projectors.
6.  CheCK  blenD: If the blended region appears too dark or light in relation to the rest of the 
image:
•	 Increase	 Blend Midpoint  in both projectors to “lighten” the overall blend, decrease to “darken” 
the overall blend.
•	 Adjust	 Blend Shape	 in	both	 projectors	 to	fine-tune	 change	the	amount	 of	mid-gray	 intensity	
(as opposed to black/white) in the blend.
7.  Repeat with remaining projectors / overlaps.
8.  Check completed display wall with the desired external signal.
9.  Adjust mechanical alignment if necessary to maintain perfect pixel-on-pixel alignment over 
time.
In  applications  where  you  are  projecting  only  white  or  light  images,  the  Blend  Width  may  be 
slightly higher—set according to how much overlap you have between images. Use the following 
as a guide (examples show overlapping width only — values for overla\
pping height will differ):
Recommended overlap is 12.5% - 25%
•	
Similar  to  Edge  Blending,  Black  Edge  Blending  allows  you  to  adjust  the  black  level  hues  of 
multiple adjacent projected images to create one large seamless display. Edge blending must be 
enabled in order to use the Black Edge Blending features.
blaCK eDge blenDIng PRoCeDURe
noTes:  1)  Adjust  white  levels  before  adjusting  black  levels.  2)  The  zones  in  BLB  menu 
correspond to the Edge Blend zones. If a given Edge Blend zone width is set to 0 (i.e. no blend 
on that side) then the corresponding BLB zone is disabled. It only becomes accessible when that 
Edge Blend zone is active.
Start with two projectors. Select the black test pattern for both projectors from the 
1.  Geometry 
and Color  submenu.
In the 2.  Black Edge Blending  submenu, enable black blending by putting a checkmark in the 
checkbox for each projector.
3.  Working with one projector at a time, use the center brightness slide bar to adjust the center 
brightness (brightness of the non-blended region) so that the center intensity matches that 
of the brightest blended region (the center of all images when blending a 2 x 2 display is the 
target area).

4. Use the following three color slide bars, Black Red Level, Black Green Level and Black Blue 
Level, so the black hue of each projector matches.
5.  You can choose which of the next four options, Top, Bottom, Left, Right, to use depending on 
which edge of the projector you are working with has been edge blended. The blend width 
can be adjusted to line up properly but by default it corresponds to the edge blending setting 
determined for that edge. 
 
6.  The brightness and black hues of the blended region can be adjusted in more detail in case 
fine-tuning	 is	needed	 (may	be	only	 necessary	 for	blending	 a	2	x	2	 projector	 display	because	
of blending differs for the sides and center).
noTes:  1)  The  menu  options  vary  depending  on  the  Edge  Blending  parameters.  2) You  may 
need to re-adjust the black level hues following the overlap adjustments on each blended edge. 
3) When adjusting six or more projectors, you need to ensure that the hue and brightness of each 
target area is matched at closely as possible.
As an alternative to using a keypad, most projector functions can be controlled remotely, typically 
at a controller such as a PC, via 1) simple bi-directional ASCII messaging on an Ethernet or serial 
communication link or 2) a web interface or an Ethernet network.  Using a PC interface can also 
prove to be useful in instances where extreme warping is applied and the menu items become 
illegible and hard to navigate.
VIa  asCII  MessagIng  —  Connect  a  serial  link  between  your  controller  and  the  RS232  or 
RS422  port  (recommended),  or  open  an  Ethernet  socket  (i.e.,  Telnet)  between  your  controller 
and the valid projector address. Valid ASCII codes and messages are documented in the  Serial 
Communications  document available in Appendix B.
VIa  Web InTeRfaCe — Connect your PC to the projector’s Ethernet port. In your web browser 
(Internet Explorer , for example), enter the IP address of the projector you wish to control. This will 
start  a  password-protected  application  —  enter  the  factory  default  “ccm7”  login  and  password 
to open the program. If the projector is powered up, you can access assorted menu options and 
slide bars.
Repeat  for  remaining  networked  projectors  as  desired.  Keep  in  mind  that  multiple  units  can 
be  controlled  from  one  PC,  but  each  unit  will  be  in  its  own  interface  (web  browser)  at  the  PC. 
Likewise,	you	can	make	up	to	five	separate	web	locations	to	a	single	projector.
The	 default	 login	provides	 access	to	security	 settings,	 where	you	can	define	 other	users	 with	
the same or fewer rights. Use “unlimited” rights for most applications. For all logins, the Service 
menu is still protected with its own password.
3.11  Remote Control of  the Projector 
						

							3-60
Occasionally the projector will encounter an error condition that can interrupt normal operation. 
Such  a  condition  can  be  caused  by  a  simple  invalid  keypad  entry,  an  input  signal  error  (most 
common)	or	a	system	 error.	The	manner	 in	which	 users	are	to	be	 notified	 of	error	 conditions	 is	
set in the Menu Preferences menu:
To see error messages displayed on-screen, select the “
•	 screen” or “all” option (recommended 
by Wolf Cinema).
To	be	notified	via	a	serial	communication	only,	select	the	“
•	 Rs232” option.
To	receive	both	types	of	notifications,	select	“
•	 all”.
To disable error messages (except for “invalid user key entry”, which can’t be hidden), select 
•	
“off”.
Note  that  a  two-digit  error  code  appears  in  the  status  LED  display  window  located  beside  the 
built-in  keypad  at  the  rear  of  the  projector.  Normal  operation  is  indicated  by  the  “On”  status 
code. 
InV alID UseR enTRY
A  keypad  entry  not  recognized  by  the  projector  triggers  a  short  on-screen  error  message 
identifying  the  problem.  For  example,  if  you  specify  a  channel  number  that  is  not  available, 
the message “Invalid Channel will appear. Or if you try to enter the wrong password, you’ll see 
“Invalid Password”. Press 
 or Exit to clear the message and try again.
noTe:  On-screen display of “Invalid User Entry” messages cannot be disabled, even if  Display 
Error Messages  has been set to “Off”.
An  input  signal  error  message  occurs  if  you  are  in  presentation  level  (i.e.,  there  are  no  menus 
present)  and  have  selected  an  input  on  which  the  projector  detects  a  problem.  While  menus 
remain operational and any key press will temporarily remove any displayed error message, you 
must resolve the signal problem in order to permanently eliminate the me\
ssage.
no sIgnal
The message  "No signal" occurs when there is no source signal detected at the selected input—
both HSYNC and VSYNC are inactive and the screen background is black. Connect or correct 
the signal, or try another input.
baD sYnC
The message  "Bad Sync" occurs when HSYNC or VSYNC are active but the signal cannot be 
displayed.  Such  a  condition  occurs  when  only  one  of  the  two  sync  signals  is  present  or  when 
either  sync  signal  is  unstable  or  is  the  wrong  frequency.  Correct  the  signal  or  select  another 
input.
oTheR sIgnal eRRoR Messages
In addition to the common  "Bad Sync" and “No Signal” errors, you may encounter a signal error 
message  indicating  that  HSYNC  and/or  VSYNC  are  either  too  fast  or  too  slow.  When  such  a 
message appears, check the frequencies shown in the  Information menu. If they are correct, the 
projector does not recognize the signal. On some PCs you may be able to change the settings 
to generate a compatible signal. If the frequencies shown in the  Information menu are incorrect, 
check the cabling to see where the problem might originate.

When  the  projector  encounters  a  system  malfunction,  either  a  System  Warning  message  or  a 
System Error message may appear. Both types of messages are accompanied by a numerical 
error code on the status LED display. A system malfunction can be cleared with 
Exit Exit from 
presentation	level,	but	may	indicate	the	need	for	service	by	a	qualified	service	technician.
noTe:  System  messages  appear  on-screen  only  if  Display  Error  Messages  has  been  set  to 
“Screen” or “All”.
sYsTeM WaRnIngs
A system warning indicates that a system malfunction has been detected (see Status LED Codes, 
below). A system warning message replaces any input signal message and disappears when the 
input signal status changes. While the projector will remain operational, the message indicates 
the presence of a potentially serious problem that should be investigated. You can press 
Exit Exit to remove the message, but for best results you should  reset the projector — power the 
projector down and up again with the 
 (power) key.
sYsTeM eRRoRs
A  system  error  message  indicates  that  a  serious  malfunction  has  been  detected  and  must  be 
investigated  as  soon  as  possible  (see  Status  LED  Codes,  below). The  projector  will  no  longer 
operate  and  must  be  reset  —  power  the  projector  down  and  up  again  with  the 
  (power) 
key.
The sT aTUs leD CoDes
If the status code display on the back of the projector shows one of the following values, you have 
encountered 	a 	likely 	system 	error 	requiring 	the 	attention 	of 	a 	qualified 	service 	technician 	(see	
System  Warnings  and  System  Errors,  above).  Acknowledge  and  clear  the  error  with 
Exit Exit 
from presentation level, or try resetting the projector by powering it off and on again, cooling when 
necessary. Consult Table 3.6 and contact your dealer if the problem persists.
The 	specific 	code 	number 	identifies 	the 	source 	of 	the 	error 	detected, 	and 	is 	particularly 	useful 	in	
cases  where  the  projector  is  far  away.  For  example,  the  code  “27”  means  the  lamp  could  not  be 
turned on. Error codes for this projector are listed in Table 3.6 on the next page.

Section	4	►	Maintenance
Lamp: The projector uses a Cermax® Xenon lamp to deliver its high brightness. A lamp should 
be  replaced  when  it  has  reached  its  end  of  life  or  if  a  noticeable  change  in  brightness  occurs. 
Keep  track  of  the  number  of  hours  the  lamp  has  been  in  use  (Lamp  Menu)  and  be  aware  of 
any  changes  to  brightness. These  indicators  will  help  you  effectively  maintain  operation  of  the 
projector. 
 WaRnIng  
Wait approximately five minutes after powering down the projector to allow  internal cooling fans to stop and for the lamp to cool sufficiently before  removing. 
never attempt to remove the lamp housing directly after use. The lamp is \
under  great pressure when hot and may explode, causing personal injury and/or \
 property damage.  allow cooling completely.
 WaRnIng  
Use only lamps supplied by Wolf Cinema. 
Use lamps of the correct wattage for your projector model when replacing\
.
Refer to 4.4 Lamp Replacement for instructions.
  The  north  american  rated  power  cord  is  provided  with  each  projector.  ensure  that 
you are using a power cord, socket and power plug that meets the appropriate local 
rating standards.
Use only the attachments and/or accessories recommended by Wolf Cinema.
Use	of	others	may	result	in	the	risk	of	fire,	shock	or	personal	injury.
 W aRnIng 
Use only an  aC power cord recommended by Wolf Cinema.
Do not attempt operation if the AC supply and cord are not within the specified  voltage and power range.
Do not set or rest items on the power cord. Place the projector in an area where the projector 
•	
cord cannot be abused or damaged by persons walking on it or by objects \
rolling over it.
Operate	 the	projector	 at	the	 specified	 voltage	only.	Do	not	 overload	 power	outlets	 and

Part 
Description  Frequency 
Action
Lens As required 
Clean the lens only when absolutely necessary. 
A small amount of dust on the lens has very little 
effect on picture quality.
To clean:  Use	a	soft	 microfiber	 cloth	without	 any	
chemicals. Use only a high-quality coated optics 
cleaning	 fluid,	which	 can	be	purchased	 from	
most  camera  supply  stores.  Apply  the  coated 
optics	 fluid	directly	 onto	the	microfiber	 cloth	
until moistened. Wipe in a single sweep across 
the surface of the lens. To avoid scratching the 
lens  do  not  scrub  or  rub  in  a  circular  motion. 
Discard  the  cloth  after  every  use.    Do  not 
use  cleaning  tools  treated  with  Ether.  Do  not 
use  cleaning  solvents  that  contain  ammonia. 
Use  compressed  air  to  remove  any  particles 
remaining on the lens.
Lamp As required  Clean:  Clean  if  absolutely  necessary.  Never 
touch the glass surface of the lamp. Fingerprints 
left  on  the  glass  will  seriously  degrade  lamp 
performance  or  cause  “hotspots”  which  can 
lead  to  an  accumulation  of  intense  heat  in  the 
touched area and cause the lamp to shatter.
To  clean:  Wait  until  lamp  is  cool.  Moisten  a 
clean,	
microfiber	 cloth	with	isopropyl	 alcohol	and	
gently  rub  the  surface  of  the  glass  in  a  circular 
motion until clean.

sooner if required  RePlaCe: 
Refer  to 4.4  Lamp  Replacement  
procedure later in this section.
Covers 
(External) As required Clean: Clean dust from external covers using 
a	clean,	microfiber	cloth	as	required.	
noTe: 
Before  cleaning  the  modules,  it  is 
recommended that you install the lens cap. This 
will keep dust particles from settling on the glass 
surface of the lens.

The  IR  Remote  Keypad  uses  two  AA  size,  1.5V  batteries  (preferably  alkaline).  To  install  new 
batteries: Open the battery compartment at the backside of the keypad by placing your thumb in the 
1. 
oval  depression  and  sliding  the  cover  out  about  ½  inch.  See  Figure  4.1.  Remove  the  old 
batteries and properly discard. Wait a minute or two.
Place the new batteries in the compartment, orienting the positive/negative of each battery 
2. 
according  to  the  labels  in  the  compartment.  When  the  batteries  are  in  place,  replace  the 
cover  by  placing  the  cover  ½  inch  from  its  closed  position  and  slide  it  into  place.  Do  not 
force the cover. 
noTe:  Always  wait  a  minute  or  two  when  replacing  batteries  so  that  the  internal  electronics 
discharge and can recognize the change.
Use  the  following  instructions  when  replacing  the  lamp. The  lamp  is  located  at  the  back  of  the 
projector (below the input panel) and can be accessed by removing the lamp access panel. Use 
only the Wolf Cinema approved  Lamp	for	your	specific	projector	model.	See	 Table	4.2	below.

A  lamp  should  be  replaced  when  it  reaches  its  end  of  life  (2000  hours,  typical)  or  sooner  if  a 
noticeable degradation in brightness occurs (typical in aging lamps). You can set the number of 
hours you expect to log with the lamp before replacing it, by setting the Lamp Limit in the Lamp 
menu. You can also enable a warning message to appear upon powering up the projector that 
will indicate the lamp has reached the limit you set, by entering a checkmark beside the Lamp 
Message option.
