MOUNTING INSTRUCTIONS
Mounting the Backboard or Enclosure
OUTDOOR INSTALLATION
If the payphone is to be installed outdoors, you must use an outdoor pedestal / enclosure
to mount the payphone and to prevent weather deterioration. Outdoor pedestals can be
mounted using concrete anchors. Outdoor wall-peds can be mounted using toggle bolts.
The telephone cable should be routed to the pedestal using EMT conduit. Once the
pedestal & enclosure is mounted, follow the instructions starting on page 4 to mount the
payphone to the pedestal & enclosure.
INDOOR INSTALLATION
λIt is recommended to use ¼” Toggle Bolts (with washers) to secure the backboard or
enclosure to the wall. The length of the toggle bolt depends on the thickness of the wall. Anchor
Screws may be used as an alternative to Toggle Bolts.
1. Ensure that the wall that the backboard or enclosure is to install to is flat & level.
2. The top height of the backboard or enclosure should be determined by the following:
Standard Height = 58” from floor Wheelchair Accessible = 51” from floor
3. Place the backboard or enclosure against the wall at the desired height & mark the Line
Wire Entrance Hole & Mounting Holes to be used, (the backboard or enclosure offers
10 mounting holes, although not all 10 must be used.) Use the diagram below to
ensure the backboard or enclosure is not upside down or backwards.
4. Drill through the marked holes on the wall using a drill bit similar to the size of the
toggles being used.
5. Route the telephone line cable through the Line Wire Entrance Hole.
6. Insert each toggle bolt & washer through the mounting holes being used on the
backboard or enclosure.
7. Secure the backboard or enclosure against the wall through the pre-drilled holes &
tighten each toggle bolt.

MOUNTING INSTRUCTIONS
Separating the Upper & Lower Housing
1. Insert the upper housing key into the upper housing lock (located on the right side of
the phone) & turn it 1/8 turn counter clockwise.
2. Insert the T-wrench key into the T- wrench insert (located approx. 6 inches above the
upper housing lock) & turn it 1/8 turn clockwise, until you hear the phone ‘snap’ open.
3. Slide the upper housing away from the lower housing.
Securing the Lower Housing to the Mounting Device
1. Fasten two security studs to the rear of the lower housing. (If the mounting device you are
installing to does not provide security stud holes, do not fasten security studs to rear of lower housing.)
2. Insert the telephone line cable through the line wire entrance hole.
3. Hold the lower housing against the mounting device and insert the security studs into
the security stud holes. (If you are not using security studs, you must hold the lower housing
against the mounting device while performing Step 4.)
4. Fasten four ¼ x 20 x ¾ mounting screws through the lower housing and into the
mounting device.

MOUNTING INSTRUCTIONS
Connecting the Telephone Line
A minimum of 22ma (& 44 VDC) loop current must be provided to the payphone from the Telephone Company’s Central Office. In certain
situations, due to the distance between the Central Office and the phone site, the loop current may not meet the required level of 22ma. If the loop
current is below 22ma, dial tone may not occur or the phone may experience only momentary burst of dial tone. It is recommended that the loop
current level at the phone be tested at this time to ensure that the required loop current level is present.
1. It is recommended that standard telephone / communication cable (No. 22 gauge, 2
pair or greater) be used to connect the telephone line with the payphone. Telephone /
Communication cable usually consists of 2 or more pairs of color-coded wire.
2. Connect one pair of communication cable wire to the two points of the Telco interface
box (D Marc location) that the telephone line originates from.
3. Connect the opposite end of the same pair of wire to the top left & right terminal
screws, (terminal block is located on the rear of the payphone's lower housing.)
4. Connect a proper earth ground wire to the top middle terminal to ensure safety.
Re-Connecting the Upper & Lower Housing
1. Make sure the upper housing key is in the unlock position & the “T” wrench key is in
the open position, (all the way forward.)
2. Slide the bottom-lining of the upper housing along the lining of the lower housing until
the two housings meet.
3. Turn the T-wrench key 1/8 turn counter-clockwise until it ‘snaps’ close & then remove
both keys.

A PROGRAMMING INSTRUCTIONSSTR ION
Entering the Program Mode
All program entries must be done in the program mode, using the keypad of the
payphone. When programming, one ‘beep’ represents a completed entry. Three ‘beeps’ represents an
error. To start an entry over, press the # key & wait for three ‘beeps’ & then re-try the entry. All program
entries can be done in one session in no specific order.
1. Open the upper housing of the payphone,(see Separating the Upper & Lower Housing on page 6.)
2. Ensure that the dial / hookswitch connector (JF) & the Ni-Cad battery (JD) are both
connected.
3. Push & hold the black program button (PB1) on the circuit board.
4. Take the handset off-hook,(while program button is held down.)
5. Listen for a single ‘beep’.
6. Release the program button, (after the single ‘beep’ is heard.)

PROGRAMMING INSTRUCTIONS
Blocking or Adding a Time Limit to Certain Types of Calls
This section covers how to restrict certain types of calls or add a time limit and/or keypad restriction to
certain types of calls. Before you begin programming, locate the Rate Band (4-digit code) that
represents the type of call you are programming for, (see the Call Type Band Description Table below.)
1. Make sure the phone is in the program mode.
2a. If blocking a certain call type, enter the 4-digit rate band and press the * key. Listen for one
confirmation beep.
6xxx * Example: 6082* this example would block 411 or 1411 information calls
2b. If placing a time limit and/or restricting use of the keypad, enter the following information in this
order for the call being programmed:
4-digit Rate Band, (see Call Type Description Table for list of Rate Bands)
8 Zero’s must be entered next
3-digit Time Limit (ex. 3 min. = 003, 15 min. = 015; to set the call back to unlimited, enter 255)
01 must be entered next
4-digit Keypad Allowance, (if the keypad is allowed during the call, enter 0008; if the keypad is not
allowed during the call, enter 0001)
Press the *(star) key to complete the entry; listen for one confirmation beep.
6xxx 0000 0000 xxx 01 0008 *
×××××××
Call Type Default Default Default Keypad Completes
Rate Band Setting Setting Time Limit Setting Allowance Entry

Call Type Band Description Table
This table shows the 4-digit rate band for each call type and its factory setting. The factory setting may
vary depending on what was requested at the time of order. *Definitions of local, toll & long distance
calls may vary depending on your region. Some regions have the same dialing pattern for local and long
distance calls and phones in those regions may require a rate file to be downloaded if the calls must be
treated differently (fees may apply). If you have any questions, please contact G-TEL Technical Support.

TROUBLESHOOTING GUIDE
Problem – No Dial Tone
Before You Begin Test the telephone line to determine if the problem is with the telephone
line or with the payphone.
Possible Cause 1: Telephone line dead or improperly connected
Solution: Check line for dial tone & check terminal block for proper
connections
Possible Cause 2: Handset is defective or improperly connected
Solution: Try replacing handset. Because some handsets are different from
others, check for the following patterns with the handset wires
Handset Type 1 Receiver = black / yellow Xmit/Mic = green / red
Handset Type 2 Receiver = green / yellow Xmit/Mic = black / red
Handset Type 3 Receiver = white / white Xmit/Mic = black / red
Possible Cause 3: Hook-switch contacts are shorted
Solution: Disconnect one hookswitch wire. Test hookswitch with a multi-
meter by setting the meter to ohms & placing one lead of the meter
on the disconnected hookswitch wire & the other lead on the
connected hookswitch wire. When hookswitch lever goes on & off-
hook, the meter should show signs of resistance. If the meter reads
the same when hookswitch lever goes on & off-hook, replace the
hook-switch.
Will Not Disconnect after Hanging Up
Possible Cause 1: Hookswitch contacts are shorted
Solution: See No Dial Tone, Possible Cause 3
Possible Cause 2: Circuit Board is defective
Solution: Main board & dial assembly should be sent to G-TEL Repair Dept.
No Keypad Response
Possible Cause 1: Keypad is defective
Solution: Replace keypad assy.
Possible Cause 2: Circuit Board is defective
Solution: Main board & dial assembly should be sent to G-TEL Repair Dept.
