4-8-4. Code squelch
This function gives the operator the ability to select
which stations he/she wants to listen to. Only those sta
tions that transmit the proper access code will be able to
"OPEN" squelch.
For example: when station A wishes to talk with station
B only, both stations should prearrange to be on the
same frequency, with the same access code.
Example: Frequency : 146.520 MHz
Digital code: 12345
The same procedure is used with the TM-3530A.
Station A
