Analog mode

CTCSS and CDCSS

The radio set is equipped with two pilot tone processes (CTCSS and

CDCSS) that permit to address specific individual radio sets or groups

or to receive only calls from the latter.

Important note: Make sure that you and your partner station(s)

use the same pilot tone process and the same CTCSS tone or the

same digital code! Refer to the CTCSS/CDCSS table, see page 29.

Busy channel lockout (factory setting: OFF)

For reducing interferences during radio communication, a transmit

lockout can be activated which blocks the transmission when the

channel is busy. When pressing the push-to-talk button, a beep

sounds, the green LED lights up and the radio set does not start

transmitting. The beep finishes when the push-to-talk button is

released.

When the green LED is not illuminated anymore, the channel is again

free and transmission can be started.

TOT automatic transmitter cutoff (factory setting: 180 sec.)

A permanent transmission on one channel can lead to damages on

the radio set. In case the push-to-talk button on the radio set is

actuated unintentionally (e.g. when transporting the device in a

toolbox), the function Time Out Timer avoids an unwanted permanent

transmission. If the duration of a transmission exceeds a specified

time (0 - 600 sec.), a warning signal sounds and the transmission is

automatically interrupted. The warning signal finishes as soon as

the push-to-talk button is released. Afterwards, transmission can be

started again by pressing the push-to-talk button.

Squelch setting (factory setting: level 5)

Nine levels are available for setting the squelch (level 1: very low

signal strength (noise), level 9: high signal strength).
