Operation Manual

English
VOX is equipped with two settings (sensitivity and delay), which
allow for optimal use, as explained below.
If you use an external microphone, remember to replace
the rubberized protective ap on the radio after you have
nished using it.
6.2.a Activation/deactivation of VOX mode
1. Repeatedly press the
F key until the VOX icon ashes. Below
this icon, the currently selected setting will appear (
On = VOX
activated or
Off = VOX deactivated).
2. Press the
o buttons to change the VOX mode to On or Off.
3. Press the
button to conrm the setting change and return
to Stand-by, or press the
F key to access the following menu
setting.
6.2.b Setting VOX sensitivity
Adjusting the VOX sensitivity avoids the likelihood of the radio going
into transmission mode because of environmental noise. As such,
it should be adjusted to the minimum level necessary to activate
transmission by voice.
1. Repeatedly press the
F key until LE (sensitivity level) is displayed.
The
VOX icon and the sensitivity level currently selected (from 01
to 06
) will ash on the display.
2. Press the
o buttons to select the desired level (01 = most
sensitive,
06 = least sensitive).
3. Press the
button to conrm the setting change and return
to Stand-by, or press the
F key to access the following menu
setting.
6.2.c Setting VOX delay
During transmission with VOX, a delay avoids the possibility that,
during short pauses in communication, the function does not return
the radio to reception mode. As such, this function should be set at
the minimum level necessary to guarantee optimum performance.
1. Repeatedly press the
F key until dL (delay) appears. The VOX
icon and the delay currently selected (from 01 to 06) will ash on
the display.
2. Press the
o buttons to select the desired delay time. Six
delay values are available, in increments of 0.5 seconds (01 = 0.5
seconds,
06 = 3.0 seconds).
3. Press the
button to conrm the setting change and return
to Stand-by, or press the
F key to access the following menu
setting.
6.3 Scanning functions
6.3.a Scanning all channels
445 BT can automatically search for signals throughout the band
by scanning, or selecting the channels in rapid sequence. When a
signal is detected, the scanning pauses on that channel and remains
blocked until the signal ends (for a maximum of ten seconds), giving
the user a chance to respond to a call, if necessary, before 445 BT
automatically begins scanning again. To begin scanning, follow the
steps outlined below:
1. Repeatedly press the
F key until the Scan icon and the currently
selected channel blinks on the display.
2. Press the
o buttons to activate scanning. The transceiver will
begin to explore the band channels.
3. The transceiver will continue channel scanning until it picks up
a transmission. When this happens, the transceiver temporarily
halts scanning and remains tuned on that channel for about 10
seconds. During this time, you have the following options:
• If the communication does not interest you, wait for 10 seconds
