The priority alert function allows you to monitor mem

ory channel 1 for activity even when you are tuned to a

different channel number. When the Priority Alert

function has been activated the microprocessor will

switch the transceiver to the frequency stored in mem

ory channel 1 once every 5 seconds. The transceiver will

determine if a signal is present. If no signal is present

the transceiver will return to the original frequency. If a

signal is present, a beep will sound from the speaker to

signal the channel is busy. This whole process takes just

a fraction of a second, so you will not see the display

frequency change. The only thing you will notice is a

momentary pause in the signal on the currently dis

played frequency. To activate the priority alert func

tion:

1. Ensure the frequency you wish to monitor has been

entered into memory channel 1.

2. Adjust the SQL control to the threshold point.

3. Press the F key momen- _

tarily, and then

has been activated.

4. If a signal is present a beep will be heard from the

speaker.

5. To turn this function off repeat step 3. The AL indi

cator will turn off.

Note:

During the period memory channel 1 is being scanned you will not

hear voice communications, only the beep will be heard if a signal is

present.

5-6 REPEATER OPERATIONS

5-6-1 Transmitter Offsets

All radio repeaters utilize a separate receive and trans

mit frequency. The receiver frequency may be either

above or below that of the transmit frequency. The

configuration of most repeaters will fall into one of the

categories listed below:

Offset Direction

To select the desired transmitter offset direction press

the SHIFT/AL key. Each time you press the key the

transceiver will advance from one direction to the next,

Automatic Offset Selection (TM-241A U.S.A. version)

The TM-241A has been programmed according to the

standard ARRL (Amateur Radio Relay League) Band

Plan with regard to transmitter offset direction. Please

see the accompanying chart for addition information

on this programming. You can, of course, override this

by using the SHIFT/AL key if desired.
