The radio will begin transmitting when a noise or voice is heard. Ensure
that you speak directly into the microphone of the radio at a distance of
less than 5cm. There are many headset options (see optional
accessories below) which can be used in VOX mode allowing for full
hands-free communication.
VOX level
The sensitivity level of the microphone can be adjusted to allow different
volumes of sounds to make the radio begin and remain transmitting.
There are 1-9 levels with 9 being the highest and most sensitive to lower
volumes of sound. If the radio is used in a very noisy environment it is
recommended to use a low sensitivity level to avoid the radio transmitting
unnecessarily. At low sensitivity level it will be required to speak loudly
into the microphone to activate the radio. At high sensitivity, a soft voice is
all that is required.
VOX Delay time
Once the radio senses a voice and begins transmitting it is possible that
the volume of the voice is lowered or there are pauses in the message
which may cause the radio to stop sending. A VOX Delay time (0.5-3S)
will keep the microphone active for the set time before returning to
receiving mode. This delay time can be chosen to suit your style of
speaking and avoid the message breaking up.
Battery Capacity Indication
Either side key can be programmed to enable this function. The
remaining charge on the battery will be voice indicated using a number
1-4. This is useful in determining when to charge the radio.
4 – Half to Full
100-40%
3 – Medium
39-30%
2 – Semi-low
29-20%
1 – Low
19-0%
SK2 is Factory programmed on Battery Level checking (short press)
Low Battery Alert
When the battery capacity is getting low and indicates a level of “1”, the
radio will alert you with a message “please charge the battery” every 5
seconds unless the radio is recharged.
Note: If the Voice Announcement function is disabled, the radio will
sound a double beep “di di ” sound when going flat.
Call Ring
The side key can be set to transmit a loud 3 second call ring tone to alert
other radios.
SK1 is Factory programmed on Call Ring, Hold in to activate.
Emergency Alarm
Either side key can be programmed with a siren alert as an emergency
notification. When pressed, the siren will be sounded on both the sending
and receiving radios. The siren will stop once the side key is pressed
again, the sending radio is switched of or the time-out timer limit is
reached.
Announce Voice Channel
As the channels are changed, a voice announces the specific channel.
This is useful when using the radio at night. Either side key can be
programmed to activate / deactivate this function.
Factory programmed on English
PTT ID
Each radio can be allocated with a 15 digit ID consisting of digits 0-9 or
A,B,C or D. The PTT ID recognition signal can be set per channel or the
side key can be programmed to activate / deactivate it. The radio can be
programmed to send the ID either at the beginning and/or end of a
transmission. The PTT ID or automatic number identification (ANI) is
used to connect with a repeater or telephone system, or for a control
centre’s communication management to identify this caller’s ID using
