INSTRUCTION MANUAL
KENWOOR,
Illustrated is the USA version.
You are the owner of our latest product, the new TM-201A
transceiver. Please read this instruction manual carefully
before placing your transceiver in service. The unit has been
carefully
engineered
and
manufactured
to
rigid
quality
stan-
dards, and should give you satisfactory and dependable
operation for many years.

frequency when transmitting.
For operation other than that of a repeater, place this switch to the ‘’S’’ posi-
fou tion. This equalizes the transmit frequency with the receive frequency.
aa “4+ setting shifts +600 kHz; ‘‘—"’ setting shifts —600 kHz from the
receive frequency when transmitting.
This operation is only effective in VFO and MR (M1~M3) operations.
If a shift frequency goes beyond the operating frequency range when depress-
ing the PTT switch to transmit, a beep will sound three times to indicate the
misoperation.
However, transmit frequency is emitted in simplex mode.

Then replace with a new fuse of the same rating.
° After completing the wiring, wrap the fuse holder with tape to protect against

@ FIXED STATION INSTALLATION [general]
¢ Power supply A regulated DC power supply (13.8 V DC, 5.5 A or more) is required.

ply.

e Antenna 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-201A protective circuit to operate, reducing the transmit output
power.
Yagi
antennas
(ARRAY)
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
(DX) or communication with a
specific party.
(having excellent directivity and
antenna is generally used for local
operation.)

After verifing the initial setup of controls and switches, proceed as follows:
(1) Turn the POWER/VOL control to turn on power. The indicators on the
display light to show the transceiver is operating.
(2) As the POWER/VOL contro! is turned clockwise, either noise or a QSO is
heard.
(3) To eliminate the no-signal noise, use the SQUELCH control. For SQUELCH
control operation, refer to next explanation.
(4) Tune to the desired frequency using MAIN DIAL.
To eliminate receiver noise at the no-signal condition, slowly adjust the squelch
clockwise until the noise disappears and the BUSY indicator goes off (threshold
point).
When a signal is received, the squelch will open, the BUSY indicator will light
and the speaker will operate.
The SQUELCH control is also used for scan operation control. If the signal is
weak or fades during mobile operation, readjust the squelch for constant
reception

1) The TM-201A antenna impedance is 50 ohms. Be sure to use only an
antenna of 50 ohms impedance.
2) Check the intended transmit frequency before operating to prevent in-
terference with other stations.
3) Pressing the microphone PTT switch places the transceiver in transmit
mode; the ON AIR indicator will light and the LED bar meter shows
transmitter power. Recommended talk distance to the microphone is ap-
proximately 5 cm.

@ 16 key AUTO PATCH OPERATION (For U.S.A. version)
To operate, hold the mic PTT switch depressed until keys are started operating.
Note:
1. When the tone encoder is started operating, the transceiver is in transmit
mode even with the PTT switch released.
2. More than about 0.8 seconds keying interval restores the transmit mode
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 the mic built-in VR 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.
@ VERIFICATION BEEP TONE
When operating, the beep sounds to indicate operation. Beep level can be ad-
justed by the potentiometer inside. (page 18)

During VFO A or B operation, depressing the mic UP or DWN switch initiates
scan programmed within the range set between receive and transmit frequen-
cies designated in memory channel 5.
As shown in the figure, R denotes the receive frequency in CH 5; T denotes the
transmit frequency in CH 5.

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

Scan resumes regardless of signal when
4 | Scan resume operating the tuning control or UP/DWN
switch
Holding the UP/DWN switch depressed allows
rapid up or down scan.
Holding the MHz key depressed allows rapid
scan in 1 MHz steps
5 | Rapid scan
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.
6 | Scan direction
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.

5. MAINTENANCE AND ADJUSTMENT
M COVER REMOVAL
1 Loosen 5 screws ($2.65 mm) of the side
panels.
2 To remove the top cover, remove 2 screws
(@2.6x 5 mm).
qo 3 To remove the bottom cover, remove 5
Loosen screws (62.65 mm).
@ BEEPER ADJUSTMENT
Adjust VR1 on the B unit (X53-1340-11/61) to your listening preference.
@ LITHIUM BATTERY
A lithium battery is contained in the transceiver to retain memory. Therefore,
U7 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.
mM MICROCOMPUTER RESET
Depress the reset switch with a nonconductive rod through the reset opening
of the bottom cover as shown

array D9, referring to the table.
Example: To set to 94.8 Hz, cut D9 diodes as shown.
To mount the D9, use a 45-W (or less) soldering pencil and
solder sparingly, heating the connections only long enough ]
to insure a good solder joint. Do not over heat.

Example: To set to 100.0 Hz, set the dip switch as shown.
. Mount the supplied diode array D9 (frequency preset) in the TU-3 unit as
shown.
. Loosen five screws on both side of the transceiver.
. Remove two screws from the top cover. Lift the rear part of the cover and
remove it.
. Peel the waxed sheet off the cushion and affix the cushion to the TU-3 PC
