The T2020
II
now repeatedly scans through all programmed channels, searching for activity. When
activity is detected on a channel, the scan is halted, and the display window shows the active channel’s
name. (If signalling options are active in the radio, only activity with valid signalling tones halts the
scanning.) The radio pauses and unmutes on that channel, as long as the traffic remains, and the
SCAN indicator flashes. Scanning resumes after a short delay, once the traffic disappears.
You may change channel if you wish, but this cancels Scan mode. Otherwise, converse in the normal
manner and, when finished, place the microphone back on its hook to restart the scan.
To Stop Scanning
Scan mode is cancelled by selecting any non-scanning channel. The SCAN indicator then disappears
from the display window.
Making a Call
If you wish to make a call when the radio is in Scan mode, you may lift the microphone off-hook at any
time to suspend scanning. If the radio has halted scanning to monitor the traffic on a channel, it remains
on that channel when you lift the microphone off-hook. If the radio has found no traffic (i.e. has not
halted), it reverts to the preprogrammed home-channel.
Using Selcall (Selcall Option Fitted)
By using Selective Calling (Selcall), you can make calls to specific individuals or groups, on particular
channels. To use Selcall, your T2020
II
must be fitted with a Selcall module, and each channel prepro-
grammed to provide its own Selcall identity.
Making a Selcall Call
Call another party using Selcall, as follows:
1. Check that the radio is on the correct channel and that the channel is clear before attempting to
make the call.
2. Select the appropriate channel for the party you wish to contact (see ‘Selecting a Channel’).
3. If your radio is programmed with the ability to make a ‘one touch’ call to one other user (usually
your base or despatcher), press the Call (
) key for about one second. The TX indicator
appears in the display briefly, and your radio sounds a short
beep
as the call is transmitted.
