TROUBLESHOOTING HINTS

1. The bell does not ring.

When the PAGE SW of the
base is pressed, does the
ringer on the handset ring?

When the TEL SG is joined
with the base to make bell
signal, is there pulse wave at
pin 4 of IC4?

Is there pulse wave at
pin 21 of IC5?

Check IC5 and its
peripheral circuit.

Check IC4 and TEL network
circuit.

Check R58, C45 and R59.

See 2. The bell does not ring
& page does not ring.
