Kenwood TM-521E - Manual (Page 13)

(With the TM-521E)
1. Press the ALT key. The ALT indicator will turn on
and the receiver will automatically center itself
on the incoming signal.
2. To release the ALT system, press the ALT key.
The ALT and the Direction indicators will turn
off.
■ ALT operation using the RC-10.
Use the following procedure to turn on the ALT func­
tion with the RC-10 Remote Controller.
1. Press the F key. The F indicator will turn on for 5
seconds.
2. While the F indicator is on, press the 1 key. If
you do not press the 1 key while the F indicator
is on you will have to start over at step 1.
To release ALT System operation, repeat steps 1
and 2. Please refer to the Instruction Manual provid­
ed with the RC-10 for instructions on programming
other RC-10 functions.
4-2-5. Confirmation Tones
An audible tone will sound whenever the TUNING
control is rotated (except in the VFO and Memory
Channel modes), or any keys or the microphone
UP/DWN switches are depressed. If you do not want
this audio confirmation, press the M.IN key and then
the CTCSS (ALERT with the U.K. and European ver­
sions) key. Whenever the M.IN key is pressed, the M
indicator will turn on. You must complete the desired
action within 5 seconds, or the M indicator will turn
off. If the indicator goes off, you must press the
M.IN key again.
To restore the confirmation tone press the M.IN key
and then the CTCSS (ALERT) key again.
4-3. TRANSMISSION
Cautions:-----------------------------------------------------------------------
1. Ensure that an antenna with a low standing
wave ratio (SWR) is attached to the antenna
connector before attempting to transmit. Failure
to provide proper termination may result in
damage to the final amplifier section.
2. Always check to ensure the frequency is clear
before transmitting.
1. Select the desired operating frequency using any
of the methods described above.
2. Check the frequency to see if it is occupied
before you transmit.
3. Press the microphone PTT switch. The ON AIR
indicator will light.
4. Speak into the microphone. The recommended
distance to the microphone is 2 inches (5 cm).
Talking too far away may result in reports of
weak audio.
5. Release the microphone PTT switch to return to
the receive mode. The ON AIR indicator should
go out.
4-4. MEMORY
4-4-1. Microprocessor Reset
A lithium battery is contained in the transceiver to re­
tain memory. Turning off the POWER switch,
disconnecting the power cable, or a power failure
will not erase memory. The battery should last for
approximately five years. For replacement informa­
tion please refer to Section 5-5 MICROPROCESSOR
BACKUP LITHIUM BATTERY REPLACEMENT.
4-4-2. Microprocessor Initialization
When you want to erase all programmed data, or if
the display should show erroneous information, you
should reset (initialize) the microprocessor using the
following procedure.
1. Turn the POWER switch off.
2. Press and hold the VFO/M and the M.IN keys and
turn on the POWER switch. * *
VFO/M_^M.IN MHz LOW POWER
B
3. Release the VFO/M and the M.IN keys; the M in­
dicator and the Memory Channel Number will
display for approximately 5 seconds after you
release the keys.
4-4-3. Memory Channel
This transceiver provides 14 Memory Channels
(0-9, A-d). In addition to serving as a normal memory
channel some of the Memory Channels serve a dual
purpose to specify other parameters. The functions
of these Memory Channels are described below.
* Memory Channel 1 is used to store the frequen­
cy for the Priority Alert function. (TM-221ES/
421ES only)
* Memory Channel A is used to store the lower
limit for the Programmable Band Scan function.
* Memory Channel b is used to store the upper
limit for the Programmable Band Scan function.
* Memory Channels C and d are used to store odd
split repeater data.
