Squelch
The squelch level is used to adjust the threshold at which signals will open the audio channel. A low
level will allow weaker signals to be audible, although with more background noise. However, if weak
signals are annoying, the level can be adjusted higher to open the channel only when stronger
signals are received.
You can set up the squelch level from 0 to 9. The higher the squelch level, the less noisy is the signal
as only stronger signal are accepted. The lower the squelch level the noisier the signal is, as weak
signals are also allowed. As the communication range or obstructions between radios increase, the
weaker the signal becomes. It is advised to use a lower squelch level to get further communication
range.

Time-out Timer
The purpose of the Time-out Timer is to prevent any person jamming up a channel for a long time
whilst transmitting. If the time that you continuously transmit exceeds the set Time-out time, the
transceiver will stop tra
nsmitting and a tone “beep” will sound. To stop the tone, release the PTT
switch. You can press the PTT switch again to resume transmitting.
Note:
you can set up the tim
e level: 15s, 30s, 60s, 90s …… 600s
Factory programmed on TOT 60s
Password Protecting Programming
The programming of the radio can be protected using a 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 or
write the radio. If the password is forgotten, you must contact your dealer to reset it as they will
require special software
.
NOTE: It is not possible to overwrite or factory reset the programming so it is essential to be
careful when changing passwords.
VOX (Voice-operated Transmission)
The TX-8 has a 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. There are many headset options (see optional accessories below) which can be used in
VOX mode allowing for full hands-free communication.
Note that VOX can only be activated in software and not manually.
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 which enable the radio to be placed at a further distance
from the noise source (typically 30cm max).
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 to 3 seconds, 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.
