04 - TX Power Level (POWER)
Allows the user to select TX power level in which the radio will operate
on the current channel. Selecting ‘LOW’ can extend the radio’s battery
life.
LOW: the value is 1 Watt. Used when communication in close
proximity, and to keep the radio from transmitting into other
geographical groups operating on the same frequency.
HIGH: The value is 4/5 Watts. Used when a stronger signal is needed
to extend transmission distance.
Note: this item will be invalid in PMR version.
05 - Transmit Time-out Timer (TOT)
The Time-out Timer prevents callers from using a channel for an
extended duration. If you continuously transmit for the duration
programmed (default is 60s), transmission will automatically stop and
an alert tone will sound. To stop the tone, release the PTT button.
06 - Squelch Level (SQL)
A squelch eliminates background noise. Higher level settings will keep
the squelch ‘closed’ more tightly for quieter monitoring, but weak
signals will not be heard. Lower settings allow weaker signals to ‘open’
the squelch but noise may also cause it to open. The radio has 10
(0~9) squelch levels:
0 – Squelch turns off (monitor on condition)
1 – Maximum sensitivity (minimum squelch)
9 – Minimum sensitivity (maximum/tight squelch)
07 – Priority Channel (PRI CH)
Set the priority channel from all the memory channels. This channel
will be detected always when priority scanning is activated.
08 – Scanning Mode (SCANMO)
There are two scanning modes: normal and priority.
Normal: while in normal mode, short press P2 side button to activate
the channel/frequency scanning function. The radio will automatically
scan from current channel through all the channels until an active
channel is detected, the radio will stop scanning for 5 seconds.
Priority: when priority channel is pre-set through Menu 07 or
