Transmit Timer

Your T2020

II

is fitted with a preprogrammed timer to limit the maximum length of trans-

missions. When the time limit is reached, the radio sounds a three tone warning, and trans-

mission is terminated.

Economy Mode

The T2020

II

incorporates an Economy mode which conserves battery power by turning off

some internal circuitry, and dimming the control head back-lighting. This occurs after a prede-

termined period of inactivity.
When Economy mode is active, the display backlighting dims or switches off.
Operating any of the control head controls, or the 

PTT

 key, restores the radio to full activity

immediately.

Scanning Channels

Your T2020

II

can be programmed with the scanning facility, which enables it to sequentially

monitor a number of channels, pausing its search when it detects activity on a channel. To

change the channels included in your scan group, refer to “User Programmable Scan”.

To Activate Scanning

Set the radio scanning through a list of preprogrammed channels, as follows:

●

Ensure the microphone is placed on its hook. (Your radio may be programmed to scan

whenever the microphone is off-hook. Consult your Tait dealer for more information on

this feature.)

●

Select the appropriate scan group in the same way as selecting a channel (see “Select-

ing a Channel”). The 

SCAN

 indicator appears in the display window, and scanning com-

mences.

SCAN

T2000

II

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 preprogrammed 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 at-

tempting to make the call.

2. Select the appropriate channel for the party you wish to contact (see “Selecting a Chan-

nel”).

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.
