6 Canceling Signal Squelch

Squelch will not open when operating in the paging mode when the paging codes do not match. It is possible to reprogram the transceiver so that squelch will open regardless of the incoming page code.

Even when signal squelch is canceled, a beep sounds and the individual code of the local station is displayed when the proper code is received.

Canceling signal type squelch

1Press and hold the F key for longer than one second, then press the CALL key.

2To return signal squelch to the original state, repeat step 1.

7 Locking Out Codes

You can lock a Paging function code only during reception. The Paging code will be transmitted even if it’s locked out. The squelch unlocks if an individual code is stored in memories A and 1 through 6 and the codes match.

This remains true even if one local station communicates with another and the code is not locked out. Locking out codes is desirable when you call another group member, but don’t want to receive communications between other individuals in the group.

To Lock Out Codes

1Enter the code setting mode (page 39) and use the tuning control to display the memory channel number to be locked out.

2Press the F key, then press the 0 key. The * indicator displays and memory locks out.

3To cancel, repeat step 1 and 2.

8 Answer-Back

(U.S.A., CANADA versions only)

If this function has been enabled and you receive a signal with your paging code, the transceiver automatically transmits your code back to the person paging you to receipt of the signal.

This function is used with the Tone alert system.

Function setting

1 Press and hold the MHz key, then turn the power on. When you hear the beep, then release the MHz key.

2Press the F key, then press the 5 key to select the Tone alert system.

To return to the normal function, perform step 2 again.
