* SQUELCH LEVEL
The purpose of the Squelch is to mute the speaker when no
signals are present. With the squelch correctly set, you will
only hear sound when a signal is present.
* TIME-OUT TIMER (TOT)
The TOT limits the length of a users transmission. The purpose
of the TOT is to prevent transmitting for a long period of time,
causing thermal damage to the radio. And alert will sound when
the limit for that transmission has been reached.
Scanning is used for hands off monitoring of your favorite
frequencies. When the transceiver options are set to SCAN (via
software), setting the channel selector to channel 16 directs
the radio to scan the selected channels from 1-16.
1. Transceiver stops scanning when a signal is detected and
continues when signal is gone.
2. If there are less than 2 channels, it cannot scan. (Go
3. On channel 16, Press and Hold the PTT and
MONI buttons while
switching ON the transceiver to turn the Scanning ON or OFF.

VOX eliminates the
need for using the PTT key to transmit. The transmitter is keyed
when the VOX circuit senses you are speaking into the
1. When operating the VOX function, set the VOX Gain level to
recognize the desired sound level.
2. If level is too sensitive, transceiver will key with noise in
3. If level is not sensitive enough, it will not pick up your

CHANNEL LOCK-OUT (BCL)
BCL prevents you from transmitting on a channel if a signal is
present. Pressing the PTT switch while a channel is in use will
emit an alert tone and inhibit the transmitter.
* BEEP TONE
If turned on, radio will give short tone to indicate that
there is nothing programmed for that channel.

CTCSS / DCS Description
You may sometimes want to hear calls only from specific persons
or groups. This option allows you to ignore unwanted calls from
others on the same frequency. These tones are sub-audible
(cannot be heard) and are selectable via software.
Note: These tones do NOT cause your conversation to be private
or scrambled. It only relieves you from listening to unwanted
