Monitor Momentary
The squelch circuit on the transceiver mutes the speaker automatically, when
no signals are present. So you will not hear background noise. Press the
Monitor key to deactivate the squelch manually. This is useful when you want
to adjust the volume level, or when you need to hear a weak signal. Monitor
Momentary will remove squelch so all background noise will be heard and all
tones (QT/DQT) accepted on the same frequency.
The LED indicator lights green while the radio is in Monitor mode.
SK1 is Factory programmed on Monitor Momentary
VOX (Voice-operated Transmission)
The ZA-725 has innovative state-of-the-art technology not seen in other
two-way radios with its multi-level sensitivity built-in VOX function. You can
enjoy talking and listening without pressing PTT key as transmit is
automatically activated by sound. This turns your radio into hands-free “walk
& talk” when used with a headset. Voice activation is used to operate the
radio in hands-free mode or as a noise / baby monitor. 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
Priority Scan
Normal scan will sequence through all the channels in
order until a signal is detected. Priority scan allows one
channel to be checked more often which is useful when
there is one main or more busy channel.
For example: If CH2 is set as a priority channel. So the
scan method will be:
Normal scan
is CH1, CH2, CH3, CH4……According to
the sequential scan.
Priority scan
is CH1, CH2, CH3, CH2, CH4, CH2……
checks same channel in between others.
Scan Modes
There are two modes of scanning depending on the user’s type of
communication.
Carrier:
Scan will stop and lock when a signal is received and continue
scanning after the signal has gone for 5 seconds.
Time:
Scan will stop when a signal is received and continue scanning 5
seconds later.
Scan Add/Delete
You can add a channel to the scan group or delete it from group.
Add
choose Yes in the channel row under the Scan Add column to add the
channel.
Del
choose No in the channel row under the Scan Add column to remove the
channel.
Password Protecting Programming
The programming of the radio can be protected using a 6 digit software
password. Once a password is programmed and written to a radio, the user
must enter the password in the software before being able to read the radio.
If the password is forgotten, you must contact your dealer to reset it. It is still
possible to overwrite the programming as normal as no password is required
when writing only when reading.
