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.
