TROUBLESHOOTING
GENERAL INFORMATION
Your transceiver has been factory aligned and tested to
specification before shipment.  Under normal
circumstances, the transceiver will operate in
accordance with these operating instructions.  All
adjustable trimmers, coils and resistors in the
transceiver were preset at the factory.  They should only
be readjusted by a qualified technician who is familiar
with this transceiver and has the necessary test
equipment.  Attempting service or alignment without
factory authorization can void the transceiver warranty.
When operated properly, the transceiver will provide
years of service and enjoyment without requiring further
realignment.  The information in this section gives some
general service procedures requiring little or no test
equipment.
Service
If it is ever necessary to return the equipment to your
dealer or service center for repair, pack the transceiver
in its original box and packing material.  Include a full
description of the problems experienced.  Include your
telephone number, fax number, and email address (if
available) along with your name and address in case the
service technician needs to contact you for further
information while investigating your problem.  Do not
return accessory items unless you feel they are directly
related to the service problem.
You may return your transceiver for service to the
authorized KENWOOD dealer from whom you
purchased it or to any authorized KENWOOD service

center.  A copy of the service report will be returned with
the transceiver.  Please do not send subassemblies or
printed circuit boards; send the complete transceiver.
Tag all returned items with your name and call sign for
identification.  Please mention the model and serial
number of the transceiver in any communication
regarding the problem.
Service Note
If you desire to correspond on a technical or operational
problem, please make your note short, complete, and to
the point.  Help us help you by providing the following:
1Model and serial number of equipment
2Question or problem you are having
3Other equipment in your station pertaining to the
problem
4Meter readings
5Other related information (menu setup, mode,
frequency, key sequence to induce malfunction, etc.)
Do not pack the equipment in crushed newspapers for shipment!
Extensive damage may result during rough handling or shipping.
Note:
uRecord the date of purchase, serial number and dealer from
whom the transceiver was purchased.
uFor your own information, retain a written record of any
maintenance performed on the transceiver.
uWhen claiming warranty service, please include a photocopy of
the bill of sale or other proof-of-purchase showing the date of
sale.

Cleaning
The keys, controls, and case of the transceiver are likely
to become soiled after extended use.  Remove the
controls from the transceiver and clean them with a
neutral detergent and warm water.  Use a neutral
detergent (no strong chemicals) and a damp cloth to
clean the case.
BACKUP BATTERY
This transceiver uses an EEPROM to store memory
channel data, menu configurations, and all necessary
operation parameters.  So, you never have to worry
about replacing back-up batteries to operate the
transceiver. 
						

							111
MICROPROCESSOR RESET
If your transceiver seems to be malfunctioning, resetting
the microprocessor may solve the problem.  The
following 2 reset Modes are available.  When performing
the reset, you may lose memory data and stored
information.  Back up or write down important data
before performing the reset.
Initial Settings
The factory defaults for the operating frequencies are as
follows:
¥ TH-K2AT/ E/ ET: 144.000 MHz
¥ TH-K4AT/ E: 430.000 MHz
The Memory channels have no data stored.  The
Weather Radio frequency (AL channel) is restored as
162.550 MHz (TH-K2AT K/ K2 only).  Refer to pages 53,
55 and 87 for the Call Channel, Weather Radio
frequency and frequency step size default values.
Full Reset
This resets all transceiver parameters to the factory
default values.
VFO Reset
This resets the transceiver parameters excluding the
stored DTMF Number in Memory {page 77} and
memory channel contents.
Note:  While transceiver is operating in the Channel Display Mode{page 57}, you cannot reset the transceiver. 
						

							112
Performing Reset
There are 2 ways to enter the Reset Mode selection.
However, the transceiverÕs Lock function must be turned
OFF {page 88}.
When the transceiver is turned OFF:
nFull reset

¥ All indicators are lit.
2Release [F].
¥ The full reset confirmation message, ÒFL.RST?Ó,
appears.
3Press [F] to proceed.
¥ ÒSURE ?Ó appears.
¥ Press any key other than [F], [LAMP] and
[MONI/SQL] to exit the Reset Mode.
4Press [F] to reset the transceiver. 
						

							113
nVFO reset
1Press [VFO]+[  ] (POWER).
2Release [VFO].
¥ The VFO reset confirmation message, ÒVF.RST?Ó,
appears.

OPERATION NOTICES
The transceiver has been designed and engineered to
avoid possible hardware glitches.  However, you may
notice the following symptoms when you operate the
transceiver.  These symptoms are not malfunctions.
Operating Voltage
As stated in ÒSPECIFICATIONSÓ {page 122}, this
transceiver operates on 6.0 V ~ 9.0 V DC (battery
terminal) or 12.0 V ~ 16.0 V DC (DC IN jack).  If you
find that the transceiver cannot be switched ON, or
ÒDC ERRÓ appears, the supplied power source may be
outside of the specified range.
In such a case, remove the DC power cable from the
transceiver immediately and confirm that the power
source voltage is within the specified range.
If you are using a variable DC power supply to operate
the transceiver, adjust the DC power supply voltage to
13.8 V DC.  Considering the output power efficiency and
thermal characteristics of the transceiver, this is the
optimal voltage to operate the transceiver.  If the voltage
at DC IN jack exceeds 14.5 V, the transceiver output
power is  automatically reduced to Ò
Ó power.
Receiving Signals in Cities
When you receive signals in cities, the receiverÕs entire
S-meter may light up without receiving any strong
signals.  This happens when the RF amplifier in the
receiver is overloaded by strong interference signals
that are nearby. 
						

							116
Transmission
If you continuously transmit for more than 8 minutes
at high power (5 W), the transceiver becomes warm.
If you continue or repeat the transmission before the
transceiver cools down, the thermal protector gradually
decreases the output power down to 1.5 W.
Ò
Ó also blinks at the same time.  If this happens, let the
transceiver cool down for a while before transmitting
again.
Internal Beats
On some spots of the frequency {page 121}, the
S-meter moves without receiving any signals or you
cannot receive any signals.  This is inevitable when you
use super-heterodyne receivers.  If this happens,
access Menu No. 28 (BS) and select ÒONÓ.
