INSTALLATION [general]
A regulated DC power supply (13.8 V DC, 9.5 A or more) is required.
It is recommended that the PS-430 be used for a power supply.
Use of the PS-430
NOTE:
Preferably, voltage should
be adjusted to 13.8 V DC.
Current capacity is more
than 9.5 A.
The regulated supply should
be equipped with a built-in
Ground plane
antenna
protection circuit for both
overcurrent and over-
voltage.
CAUTION
A battery charging power
supply cannot be used.
TM-201B ~7s ~~ di }
Various types of fixed station antennas are commercially available, select your
desired antenna according to your installation space and application.
Note that the SWR of your antenna should be less than 1.5. A high SWR will
cause the TM-201B protective circuit to operate, reducing the transmit output
power.
Transceiver performance depends
largely on the type of antenna used.
For fixed station operation there are
ground plane antennas (omni-
directional) and Yagi antennas (uni-
directional). The Yagi antenna is
suitable for long distance operation
(OX) or communication with a
specific party.
(having excellent directivity and
antenna is generally used for local
operation.)

To operate, hold the mic PTT switch depressed until after the first key has been
depressed.
Note:
1. After PTT operation is initiated, the transceiver will remain in transmit
mode even with the PTT switch released.
2. More than 0.8 seconds keying interval between digit entry will return
the radio to receive mode.
3. The touch-tone encoder level can be readjusted according to your re-
quirement.
When readjusting, set the deviation to 3 kHz by using the built-in VR (in
the mic.) with both the 3 and 6 keys of the encoder held depressed.
Next, hold both the 2 and 3 keys depressed to verify the deviation which
is within 1.2 kHz+0.3 kHz.
When operating, several beep sounds are provided to indicate operation. Beep
level can be adjusted by the potentiometer inside. (page 18)

Procedure
Operation Indication
1 | Scan range setting
Store lower and upper limit frequencies in
memory channel 5 by operating the M, M5,
tuning control UP, DWN or MHz switch.
2 | Scan start
Hold the mic UP or DWN switch depressed for
more than one second. The scan starts. The
megahertz dot starts flashing

3 | Scan will stop at a busy station and resume in 6 seconds.
4 | Scan resume
Scan resumes regardless of signal when
operating the tuning control or UP/DWN
switch
5 | Rapid scan
Holding the UP/DWN switch depressed allows
rapid up or down scan.
Holding the MHz key depressed allows rapid
scan in 1 MHz steps.
6 | Scan direction
During up scan, depressing the DWN key or
turning the tuning control one click to the left
reverses the direction.
During down scan, reversing the above pro-
cedure reverses the direction.
7 Other scan range
operation
Holding the UP/DWN key depressed allows the
scan to go beyond the upper or lower frequency
limit
Example: During up scan from R to T, hold
the UP key depressed and allow the
scan to go beyond T. The scan goes
from T to R. (Outside the programm-
ed limits)
8 | Scan release
Depressing the A/B key or mic PTT switch
releases the scan.
The flashing dot will stop.

Reset opening
A lithium battery is contained in the transceiver to retain memory. Therefore,
turning off the POWER switch, disconnecting the power cable, or a power
failure will not clear the memory. The battery will last approximately five
years. When the battery discharges an erroneous display may appear on the
LCD. Lithium battery replacement should be performed by an authorized TRIO-
KENWOOD service facility either your TRIO-KENWOOD dealer, or the factory.
Note:
When the lithium battery is replaced, the microprocessor must be reset.
Note:
Removing the battery does not require reprogramming the operating
system, only your memory channel information etc.
Depress the reset switch with a nonconductive rod, through the reset opening
of the bottom cover as shown

Example: To set to 94.8 Hz, cut D9 diodes as shown.
To install D9, use a 45-W (or less) soldering pencil and
solder carefully, heating the connections only long enough
to insure a good solder joint. Do not over heat.
. Select the desired second tone frequency by setting the 6-bit dip switch,
referring to the table.
Example: To set to 100.0 Hz, set the dip switch as shown.
. Install the supplied diode array D9 (frequency preset) in the TU-3 unit as
shown,
. Loosen five screws on both sides of the transceiver.
. Remove two screws from the top cover. Lift the rear part of the cover and
remove it.
