Canceling Signal Squelch; Locking Out Codes; Answer-Back - Kenwood TH-78A Instruction Manual

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
1 Press and hold the F key for longer than one
second, then press the CALL key.
2 To 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
1 Enter the code setting mode (page 39) and use the
tuning control to display the memory channel number
to be locked out.
2 Press the F key, then press the 0 key. The *
indicator displays and memory locks out.
3 To cancel, repeat step 1 and 2.
