Lamp CautionsThis projector uses a pressurized mercury lamp. A loud sound may 
indicate lamp failure. Lamp failure is caused by excessive shock, 
improper cooling, surface scratches or deterioration of the lamp due 
to usage. The period of time up to failure largely varies depending on 
the individual lamp and the condition and the frequency of use. It is 
important to note that failure can often result in the bulb cracking.
When the lamp replacement indicator and on-screen display icon are 
illuminated or are flashing, replace the lamp with a new one 
immediately, even if the lamp appears to be operating normally.
If the lamp breaks, glass particles may spread inside the lamp cage 
or gas contained in the lamp may be vented into the room from the 
exhaust vent. As the gas in this lamp contains mercury, ventilate the 
room well if the lamp breaks and avoid all exposure to the released 
gas. In case of exposure to the gas, consult a doctor as soon as 
possible.
If the lamp breaks, there is also a possibility that glass particles may 
spread inside the projector. If this happens, contact your nearest 
Authorized Dealer to remove the damaged lamp and ensure safe 
operation.
Do not remove the lamp unit immediately after turning off the 
projector. Touching a hot lamp can cause burns or injury. Wait at 
least one hour after the disconnecting the power cord to allow the 
surface of the lamp unit to fully cool before removing.

Lamp Replacement
1. Turn off the projector and wait for the cooling fan to stop. 
2. Unplug the power cord. Allow the projector to cool down for approximately one hour 
prior to removing the lamp assembly for replacement.
3.Loosen the two captive lamp cover 
screws and remove the cover. 
 
 
 
 
 
 
 
 
 
4. Loosen the four lamp assembly 
mounting screws.
5.Grasp the lamp assembly 
handle and pull gently, removing 
the lamp module from the 
projector housing. As you do 
so, the lamp cooling interlock 
switch on the inside of the lamp 
mounting frame (near the top) 
moves to the OFF position. 
 
 
 
6. Gently slide the new lamp assembly into the mounting frame. Align the two power 
connectors at the top of the lamp assembly with the two sockets at the top of the 
mounting frame. Press gently on both sides of the lamp assembly to snap it into 
place. As you do so, the lamp cooling interlock switch returns to the ON position.
7. Tighten the lamp assembly mounting screws. 
8. Replace the lamp cover and secure the captive lamp cover screws.
9. Plug in the projector and turn it on. 
10. Reset the Lamp Timer to zero. To do this, select Lamp Reset from the Setup menu 
and press ENTER. The RS-440 shows the number of hours the projector lamp has 
been in service and asks you to confirm or cancel the reset. Press ENTER again to 
confirm.

Troubleshooting Tips
Table 5-1 provides some general guidelines for troubleshooting problems you may 
encounter with the RS-440. If you encounter an issue not described here, please contact 
your Runco dealer or Runco Technical Support. 
Table 5-1. Troubleshooting Chart 
SymptomPossible Cause(s)Solution
The projector does not turn 
on after initial installation.  The RS-440 is not plugged 
in or the AC outlet is not 
active. 

batteries have run out.  Ensure that the RS-440 is 
plugged in and that the AC 
outlet is active. 
 Replace the batteries. 
The projector is on, but there 
is no video image on-screen.  Incorrect source selection. 
 Source component is not 
turned on.  Select the correct source. 
 Turn on the source 
component. 
A projected image from a 
DVD is split or otherwise 
scrambled.  DVD player is set to 
progressive scan mode.  Turn off progressive scan 
on the DVD player. 
 Connect the DVD player to 
the Component input. 
Image is too bright and/or 
lacks definition in the bright 
areas of the image.  Contrast is set too high.  Lower the contrast setting. 
Image appears “washed out” 
and/or dark areas appear too 
bright.  Brightness is set too high.  Lower the brightness 
setting. 
Colors in the image are 
swapped; for example, reds 
appear blue or vice versa. 
Blue/Pb outputs from the 
source are connected to 
the wrong inputs on the 
RS-440.  Ensure that the source 
outputs are connected to 
the correct RS-440 input. 
RGB-HD images appear 
“noisy.” Clock and Phase settings 
need adjustment.  Manually adjust Clock and 
Phase settings, or perform 
an Auto-Tune (refer to 
YUV/RGB Adjust on 
page 49).
The projector will not turn 
back on after it was powered 
down, or the image 
disappears during operation.  The projector will not turn 
on for two minutes after 
power-down, to protect 
the lamp. 
 The lamp has failed or was 
improperly installed.  Wait until the cooling fan 
stops.  
 
 Replace or re-install the 
lamp.

RS-232 Connection 
and Port Configuration
To interface the RS-440 with a home theater automation/control system or a PC running 
terminal emulation software, connect it to your control system or PC as shown in 
Figure 
3-13. 
Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop 
bit and no flow control. Set the baud rate to 9600, to match that of the RS-440 RS-232 
port. 
6.2 
Serial Command 
Syntax
Table 6-1 lists the RS-232 command set. All commands are in ASCII format and must be 
in UPPERCASE. 
When you send a valid command, the RS-440 executes it and acknowledges it with the 
first three characters of the command followed by “OK;” for example, “RRAOK.“ When you 
send an invalid command, the RS-440 ignores it and returns the first three characters of 
the command followed by “NG;” for example, “RRXNG.“

Notes:
1. All image quality settings must be made with the remote control. After the image adjustments 
are complete, you can use these commands to store the settings in the selected memory.
2. The power on command (PON) will not provide an OK reply; it will instead reply with a random 
character. For your automation system, simply ensure that you receive a character after the 
PON command. If you do not get any reply after PON, send PON again.
