OWNER’S MANUAL

Low Battery Warning alerts you when the battery needs to be

recharged.

While transmitting, if the power of battery goes below a pre-

determined value, the red light will flash. When a tone sounds, the

transceiver stops transmitting. Please replace or recharge the battery.

The squelch circuit on the transceiver automatically mutes the

speaker when no signals are present, so you will not hear background

noise. Press and hold "Monitor" key to manually deactivate the

squelch. This operation is especially useful for adjusting the volume

level or receiving a weak signal.

The LED indicator lights green while the "Monitor" key is pressed.

Some channels may have pre-programmed CTCSS/DCS tones. A

CTCSS/DCS tone is a sub-audible signal, which allows you to ignore

(not hear) calls from other parties using the same channel.

When you receive a signal that has a tone different from the one

set up in your transceiver, you will not hear the signal. Likewise,

signals that you transmit will only be heard by parties whose CTCSS/

DCS tone matches the tone set up in your transceiver.

Note: Although using channels set up with CTCSS/DCS tones enables

you to avoid hearing those unwanted calls, it does not mean

your calls will be private.

The Two Tone Signaling (TTS) function is used to control the

squelch to turn ON or OFF. It includes two tone call and group call.

It can be enabled or disabled by your dealer.
