Scanning
Purpose:
Permits reception only if a
call carries a special
(audible) tone sequence
which represents your
identity number.
Permits reception only if a
call has a signal above a
factory-set threshold.
This ensures that only
intelligible signals are
made audible.
To have your radio monitor a number of channels for
valid activity (transmissions carrying tones or codes
specific to you), you can use the scanning facility in your
II
T2020 . (This is an option which must be
preprogrammed.)
To set the radio scanning through a list of
preprogrammed channels:
1 Ensure the microphone is in its clip (on-hook),
2 Select a group preprogrammed as a scan group (see
"Selecting a Channel") and scanning will commence.
If the radio detects a channel with valid activity, it pauses
there and makes the traffic audible to you. When the
traffic finishes, the radio resumes scanning.
Whilst the radio is scanning, you may lift the microphone
off-hook and make a call. If it is monitoring a busy
channel, it will remain on that channel, otherwise it will
return to its preprogrammed 'home' channel.
To stop the radio scanning:
• Select another channel.
To turn on or off:
Hold the Monitor (
for more than one second.
Press briefly again to reac-
tivate.
