4-7. DTSS (Dual Tone Squelch System)

(Requires optional DTU-2)

This function allows the squelch to be turned on in the

receive mode on reception of a three-digit code matching

the DTSS code selected in your radio.

Once the squelch is turned on by reception of a matching

code, it operates normally from then on. If no signal is

received for longer than 2 seconds, the squelch is turned

off until a matching code is received.

NOTE

This function is not available in some areas.
