TRANSMITTING
1.To transmit, press and hold [ PTT ] and speak into the microphone in
your normal tone of voice.
The LED indicator lights continuously red when transmitting.
To maximize sound clarity at the receiving station, hold the transceiver 2
to 3 inches from mouth and talk in normal tone of voice.
2.Release [ PTT ] to receive.

ADDITIONAL FUNCTIONS:
SQUELCH LEVEL
The purpose of Squelch is to mute the speaker when no signals are present
(Squelch OFF). With the squelch level correctly set, you will hear sound
only while actually receiving signals (Squelch ON). The squelch level can
be adjusted via program software.
TIME-OUT TIMER (TOT)
The purpose of the Time-out Timer is to prevent any caller from using a
channel for an extended period of time which will cause thermal damage.
The built-in Time-out Timer limits each transmission time to a certain time.
The transmission time extends the certain time you set, an alert tone will
sound.
SCAN
Scan is a useful function for hands-off monitoring of your favorite
frequencies. When transceiver is set as SCAN via software, turn the
channel selector to channel 16, the transceiver will automatically detect the
activities of scanning channel from 1 to 15 (Different channel can be set) .
1.The transceiver stops scanning at the frequency (or memory channel)
where a signal is detected. It then continues or stops scanning.
2.If there are less than 2 channels, it can not scan.
3.On channel 16, press PTT and MONI key, it will turn on the SCAN, or
turn off the SCAN.
4.If the FM radio function is activated, it can not scan.
VOICE PROMPT
1.Voice Prompt ON/OFF can be set via software.
2. On channel 10, press PTT and MONI key, then switch on the
transceiver, Voice Prompt can be cancelled or activated.
3.On channel 15, press PTT and MONI key, then switch on the
transceiver to choose different voice prompt languages.
VOX(Voice Operated Transmission)
VOX eliminates the necessity of manually switching to the transmission
Mode each time you want to transmit. The transceiver automatically
switches to Transmission Mode when the VOX circuitry senses that you

have begun speaking into the microphone.
When you operate the VOX function, you must use an optional headset
with microphone.
1.When operating the VOX function, be sure to set the VOX Gain level
which allows the transceiver to recognize the sound levels.
2.If the microphone is too sensitive, the transceiver will begin transmitting
when there is noise in the background.
3.If it is not sensitive enough, it will not pick up your voice when you
begin speaking. Be sure to adjust the VOX Gain level to an appropriate
sensitivity to allow smooth transmission.
On channel 1-5, press and hold the MONI and PTT, then switch on the
transceiver, thus to activate the VOX functions ON/OFF.
EMERGENCY ALARM
On channel 11, press and hold the PTT and MONI, then switch the
transceiver on, thus to activate the emergency alarm function ON/OFF.
Also it can be set with program software. If the function is OFF, the other
transceiver receives the signal, it is not able to alarm.
Battery Saver
The battery saver function will decrease the amount of power used when a
signal is not being received and no operations are being performed(no keys
are being pressed, and no switches are being turned).
While the channel is not busy and no operation is performed for more than
10 seconds, Battery Saver turns ON.
When a signal is received or an operation is performed, Battery Saver turns
OFF.
BATTERY LOW ALERT
Battery Low Alert reminds you of recharging.
When the battery power is very low, an alert tone will sound and the LED
indicator will blink red. Please recharge or replace the battery pack.
MONITOR
When you are receiving and no signals present, the squelch function can
mute the speaker, so you can not hear the background noise. If you want to
switch the squelch function OFF, press and hold [MONI] button. It is very
helpful when you want to adjust the volume level and receive the weak
signals.

BUSY CHANNEL LOCK-OUT (BCL)
Busy Channel Lock-out function can be turned ON/OFF with program
software on every channel.
When activated, BCL prevents you from interfering with other parties
who may be using the same channel that you selected. Pressing the PTT
switch while the channel is in use
will cause your transceiver to emit an alert tone and transmission will be
inhibited (you cannot transmit). Release the PTT switch to stop the tone
and return to receive mode.
CTCSS/DCS
CTCSS (Continuous Tone Coded Squelch System)/ (Digital
Coded Squelch)
You may sometimes want to hear calls from only specific persons or
groups. In this case, use the selective call which allows
You to ignore unwanted calls from other persons who are using the same
frequency.
CTCSS or DCS is a sub-audible tone and is selectable from among the 39
or 83 tone frequency listed.
Note
CTCSS and DCS do not cause your conversation to be private and
scrambled. It only relieves you from listening to unwanted conversations.
