SERVICE
Should it ever become necessary to return the equiment
for repair, pack in its original boxes and packing, and in-
clude a full description of the problems involved. Also in-
clude your telephone number. You need not return ac-
cessory items unless directly related to the service prob-
lem.
You may return your radio for service to the Authorized
Kenwood Dealer from whom you purchased it. A copy of
the service report will be returned with the unit. Please do
not send sub-assemblies or printed circuit boards. Send
the complete unit, in its original boxes and packing. If you
want verification of receipt, please supply a self — ad-
dressed card (or letter) and you will be informed of the
date of receipt and estimated service time.
MASTER OSCILLATOR CALIBRATION
The built-in master oscillator can be calibrated using a
WWYV signal.
1. Remove the top and bottom cases.
2. Connect the second MKR terminal connector @ on the
Control unit and the RF unit M terminal with the
supplied calibration cable.
1. Receive WWV at 10 MHz or 15 MHz (with an antenna
connected.)
2. Place the Control CAL switch unit to ON.
3. The WWYV signal and the marker signal may make two
beat signals (high and low). Adjust the tuning control
for zero-beat.
4. Adjust the F.ADJ trimmer TC1 adjacent to the CAL
switch for zero-single beat.
This completes the calibration.
5. Turn the CAL switch OFF, Remove the calibration cable,
and replace the cases.
SERVICE NOTE:
Dear OM, if you desire to correspond on a technical or
Operational problem, please make your note short, com-
plete, and to the point. And PLEASE make it readable.
Please list: Model and serial number.
The question or problem you are having.
Please give sufficient detail to diagnose; other equipment
in the station, meter readings and anything you feel might
be useful in attempting diagnoses.

1. Record the data of purchase, serial number and dealer
from whom purchased.
2. For your own information, retain a written record of
any maintenance performed on the unit.
3. When claiming warranty service, please include a

chase showing the date of sale.
LITHIUM BATTERY FOR MICROPROCESSOR BACK-
UP
The TS-430S employs a lithium battery to back up
stored memories.
The life of the battery is approximately five years.
lf the display indicates 14.000.0 MHz, USB when turning
the POWER ON and OFF, this may show the lithium
battery needs replacement. This should be performed by
an authorized KENWOOD service facility — either your
dealer or the factory.
