Kenwood TM-441A - Manual (Page 28)

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

the SHIFT/AL key. The
AL indicator will turn on
in the display to remind
you that this function
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:
TM-241A/
241E
TM-441A TM-441E
European
version
TM-541A TM-541E
+ + 600 kHz + 5 MHz + 1.6 MHz + 12 MHz + 35 MHz
- -600 kHz -5 MHz -1.6 MHz -12 MHz -6 MHz
— -7.6 MHz -20MHz
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,
i.e. “+” to
to ”------- “ with TM-441Eand TM-
541A) to no offset (simplex).
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.
