1. OVERVIEW
Except for the differences noted in this appendix, the
5
Inter-Tel GX statron mstruments mstall and operate
the same as those previously outlined in this manual.
1.1The Inter-Tel GX station instruments may be used
on any Gh4X-256 System.
1.2To use the GX station instruments on the IMX 256System, there is a special software package called
Extendedplus Tl, E&M, and GX (part no. 827.8163).13

SPECIFICATIONS
A KEYSETS
2.1For a drawing of the GX 24-line keyset, refer toFigure A-l on page A-3. The 
keyset dimensions are:Height 3.5 in. (8.9 cm.)
Width 8.8 in. (22.3 cm.)
Length 9.0 in. (22.9 cm.)
Weight 2.8 lb. (1.3 kg.)
2.2Since GX keysets do not have secondary voice
path circuitry, they camr be equipped with Data PortModules and they 
canmt receive off-hook voice an-
nounce (OHVA) calls. GX 
keysets can place OHVA
calls (see page A-10 for more information).Optional Liquid Crystal Display 
&CD) Unit
23
If desired, standard GX keysets can be convertedto display 
keysets by installing an LCD Unit (part no.
828.1052). The messages shown on the display help the
user to process calls more efficiently and professionally.Optional Loud Ringing Adapter 
(LRA)
2.4GX keysets can have optional LRAs installed (part
no. 828.1051); contact Inter-Tel Customer Support for
details. The LRA provides dry contacts used in control-
ling an external signaling device. The dry contacts fol-low the ring cycle of the piexoelectric ringer of the
keyset. The LRA is not affected by the ring pitch DIP
switches on the bottom of the 
keyset or the ringer vol-
ume control. The LRA contact ratings are as follows:CONTACT

							APPENDIX A- GX STATION INSTRUMENTSINTER-TELPBACTICBSIssue 1, November 1994IMX/GMX 256 INSTALLA~ON & MAINTENANCE
NOTE: Do not connect an external signaling device
directly to the keyset without using an LRA.
Optional Speakerphone Module or External I&k
Speaker
2.5GX keysets have a built-in speaker and micro-
phone that allow the user to answer intercom calls
“handsfree,” dial while on hook, monitor calls, and lis-
ten to background music. For 
handsfree conversation on
outside calls, GX 
keysets can be equipped with optional
Speakerphone Modules (part no. 828.1077) or external
8-ohm desk speakers.
2.6If the Speakerphone Module is installed, completeinformation and installation instructions are included
with the kit.
2.7If an external desk speaker is installed, the speaker
is connected to the 
keyset by a mod-to-mod line cord
and is turned on and off using the SPKR key. A strap on
the bottom of the 
keyset must also be set to enable the
handsfree microphone for outside calls.
Changing Ring Pitch
2.8The pitch of the ring signals can be changed by the
user to create distinctive ringing. If stations are placedclose together, changing the pitch makes each station’s
ring easier to recognize. The pitch is changed by setting
DIP switches on the bottom of the 
keyset (refer to pageA-4).
B.DIRECT STATION SELECTION/BUSYLAMP FIELD 
@SS/BLF) UNITS
2.9GX lXS/BLF Units can be single units or tandem
units (two units connected together to form one large
unit). Single units provide one-key access to 
60 exten-
sion numbers; tandem units provide access to 120 exten-
sion numbers.
2.10GX DSWBLF Unit dimensions are:Height 3.5 in. (8.9 cm.)
Width 8.8 in. (22.3 cm.)
Length 9.0 in. (22.9 cm.)
Weight 2.0 lb. (0.9 kg.)
C.SINGLELINE INSTRUMENTS (SLIs)
2.11GX Single-Line Instruments (SLIs) are identical
in design and function to the 
SLIs described in the main
part of the manual.Page A-2

INSTALLA~ON
3.1The installation instructions in this appendix con-
tain information that differs 
from or is not covered in the
rest of the manual. For complete installation informa-
tion, use this appendix in conjunction with the 
INSTAL-
LAYTON section of the manual.32 When performing the loop resistance test (see
page 3-29), use the following loop limit values for GX
station instruments:

ohms/15560 ft. (4742 m.)
3.3Be sure to install the PAL Chip on the RCPU Card
(see page 3-44). This component determines the partic-
ular software package that will be used by the system.
Also, to fully enable the GX version software, perform
the programming procedure described in paragraph 5.1
on page A-10.A. 
KEYSET INSTALLATION
3.4 Before performing the installation instructions
outlined in this section, refer to the information begin-
ning on page 3-71.
Keyset Set-Up
3.5The GX keyset has speakerphone control straps,ring pitch selection 
DIP switches, and a microphone
gain adjustment thumbwheel - all located on the bot-
tom of the 
keyset. To ensure that these items are set for
proper operation, follow these steps:(1) With the baseplate removed, check that the
straps on the 
keyset bottom are connected as
shown in Figure A-2 on the next page. The key-
set will not operate properly if the straps are not
positioned as shown.
(2)
If de.&@ change the pitch of the keyset’s ring
signal by setting the DIP switches on the 
keysetbottom. (Volume level may change with pitch.)
The possible settings are shown in the following
chart (0 = open, CL = closed).
SWrrCH POSITION
RlNG 1 2 i PHigh 1CL 0 0 0
20 CL. 0 0
30 0 CL 0
Low 400 0 a
Off0000
NOTE: Combine two settings (close two or
more switches) for additional pitch settings, if
desired. It is easiest to select the ring pitch afterthe 
keyset is installed and while the keyset is
ringing.
(3)Test the 
keyset internal speaker and handsfree
microphone by receiving a 
handsfiee intercomcall. If problems such as feedback, hollow
sound, or weak transmission develop, use the
following methods to correct them.
a.If fedback occurs:1 Lower the 
keyset speaker volume by
turning the thumbwheel control on the
right side of the keyset.2 Locate the microphone gain adjustment
thumbwheel next to the DIP switches onthe bottom of the 
keyset. Begin making
adjustments with the arrow on the side of
the thumbwheel pointing away from the
keyset or slightly toward the top of the
keyset. With the handset side of the key-
set facing you, decrease the microphone
gain by turning the thumbwheel counter-
clockwise.b. If the other party hears hollow 
sound.- De-
crease the microphone gain by turning the
thumbwheel (described above) counter-
clockwise.
c.If the other party cannot hear the conversa-
tion: 
Increase the microphone gain slightlyby turning the thumbwheel (described
above) clockwise.
(4)Replace the baseplate.

Liquid Crystal Display (LCD) Installation
3.6To convert a standard GX keyset to a display key-
set, install an LCD Kit (Part no. 828.1052) as follows:
(1)
(2)
(3)
(4)
(5)
(6)
Q
03)
(9)Unpack the LCD Kit. There should be a clear
plastic display window, an LCD unit, a ribbon
cable, and two small Phillips-head screws.
Remove the 
keyset baseplate by pressing on the
top edge of the baseplate to release the tab and by
pulling the plate off.
Remove the line cord and handset cord from the
keyset. Then loosen the four screws on the bot-
tom of the 
keyset (enough so that the keyset can
be opened).
Carefully open the 
keyset to expose the back of
the keyboard that has the LCD connector. (Refer
to Figure 
3-43 on page 3-72.)
Remove the cover 
from the display opening inthetophousingofthekeysetbyreleasingthetabs
from the inside of the housing and pushing out
the cover.
From the front of the 
keyset, insert one end of the
clear plastic window in the display opening, with
the painted side of the brown edging facing the
inside of the 
keyset. Then slightly bend the win-
dow, insert the other end into the opening, and
ease the window into place.
Remove the covering from the LCD and install
as follows:a. Insert one end of the ribbon cable into the
black connector on the LCD unit. Ensure thatthe metal strips on the ribbon cable make
contact with the metal tabs in the black con-
nector.
b.With the LCD facing up, insert the other end
of the ribbon cable into the black 
comtector
on the back of the keyboard.
c.Position the LCD on the plastic window so
that the screw holes in the LCD unit and inthe 
keyset housing are aligned. Install the
screws to hold the LCD in place.
Reassemble the 
keyset.
If there is a potentiometer located underneath
the extension numberplate on the face of the kzy-
set, the LCD contrast can be adjusted. Turn the
potentiometer to lighten or darken the display.
