INSTALLATION
Mounting bracket and screws are supplied for mounting the transceiver under-
neath the dashboard. Microphone hanger and screws are also supplied.
For electrical connection first make sure that the transceiver is turned off.
Connect the red wire to the ACC terminal of the ignition switch or +
terminal of battery and ground the black wire to the chassis of the vehicle.
The black wire should be grounded as short as possible to minimize the
noise interférence.
This transceiver is designed for use with the negative ground system.
(For installation in the positive ground system see the following instructions.)
Installation in positive ground system:
a) Since the cabinet is commonly connected to all B minus Potentials in
the .transceiver the transceiver must be electricalty isolated from the
chassis of the vehicle at ail times. (See Fig. 1 for connection with power
source.)

b) Obtain a pair of 0.01 mfd. @500V ceramic capaitors. Cut the antenna
coaxial cable approximately 3 inches from the male connector. Connect
one of the 0.01 capacitors in line with the center copper wire of the
coaxial cable and solder. Tape the connections. Add the other capacitor
in line with the shielding braids and solder. Tape the entire exposed
braids and capacitor for insulation. These capacitors inline with the
conductors of the coaxial cable now isolate the antenna ground from the
ground of the transceiver. (See Fig. 2)

ANTENNA
Antenna is one of the most important factors for the operation with maximum
efficiency. A quarter wave antenna can be successfully mounted for mobile
station. The antenna impédance should be 50 ohms. For the details consult
with your distributor.
Important:
Do not operate the transceiver without a proper antenna or dummy load
connected to the antenna connector as the transmitter transistors may be
damaged.
OPERATING INSTRUCTIONS
The transceiver is ready to operate when it is instalied with an antenna
properly connected. Note that the communication range differs depending upon
the environment where the transceiver is operated. You may reach 30 or 40
kilometers where no obstacle exists but the range may be limited to 5 or 6
kilometers in cities where many high buildings disturb the communication.

1) Turn the set on by Switching the LOW-OFF-HI snap switch to the desired
channel range and the channel dial wili be lighted. Turn the volume control
clockwise to increase the audio Sound. Note that the volume control knob
is only for adjusting the audiO| volume not to in crease the transmitting
power. !
2) Set the DELTA-TUNE for best réception.
3) Turn the squelch control clockwise until incoming noise is eliminated. Do
not turn it excessively as the sensitivity may be reduced.
4) Turn the squelch control counter-clockwise to switch off the ANL
(Automatic Noise Limiter).
5) Turn the channel selector knob to the desired channel.
6) For transmitting press the button on the microphone and speak into it
normally. Release the button for receiving.
M ETE R
The meter reading indicates the signal strength at receiving and functions
as an output indicator at transmitting and the meter pointer should be
within the Red zone under the normal conditions.

CIRCUIT PROTECTION INDICATOR LAMP
The Lamp is on when the antenna is mismatched and the transmitting circuit
wili be eut off.
TONE-LIGHT CALLING DEVICE
The Model TS-660S is equipped with a sélective tone-light calling device
which works oft 1 750 Hz signal. To call the other station push the push-to-
talk button and the call button simultaneously when the calling signal is
transmitted. When the signal is received a peep tone is produced and the
call-light lamp will be lighted at the other station and the lamp stays on
until the other station answers.
Please note that the.device works only when the other station is switched
on ând that the buttons on the calling side must be depressed at least for
10 seconds.
