Kenwood Th-K2at/e, K2e/t, K4at, K4e Transceiver Instruction Manual

Note:
uNever leave the battery pack in direct sunlight.
uThe transceiver becomes warm while charging the battery pack.
uWhile the battery pack is charged, the ambient temperature must
be within 0°C ~ 40°C (32°F ~ 104°F).  Otherwise, charging does
not start.  If the transceiver senses that the temperature is more
than 60°C (140° F) during charging, the transceiver stops
charging.
uBefore recharging the battery pack, use the battery pack until the
transceiver stops receiving.
uDo not plug the charger into the DC IN jack for more than 24
hours.
uUnplug the charger as soon as possible after the charging period
is over.
uAfter the battery pack is charged, do not unplug and plug the
charger into the AC outlet again.  Unpluging the charger will reset
the charging timer and the battery pack will be charged again.
This could result in over-charging.
uIf the battery pack is recharged repeatedly before the battery
pack is not fully used, the memory effect (the battery pack will not
allow the charger to recharge the battery to more than a certain
voltage level) may occur.  In this case, turn the transceiver ON
until it stops receiving in order to discharge the battery pack, then
recharge the battery pack as normal.
uIf the battery pack is not used for a long time, the battery pack
capacity temporarily decreases.  In this case, charge the battery
and use the battery pack until the transceiver stops receiving.
Repeat this procedure a few times.  The battery pack should
recover its capacity.
uIf the charger is plugged into the DC IN jack before the battery
pack is attached, turn the transceiver power ON and then OFF
again to initiate charging.
uExceeding the specified charge period shortens the useful life of
the PB-43N Ni-MH battery pack.
uThe provided charger is designed to charge only the PB-43N
Ni-MH battery pack.  Charging other models of battery packs
may damage the charger and battery pack.
uDo not transmit while charging.
uWhen not in use, store the battery pack in a cool and dry place.
uBefore charging the PB-43N Ni-MH battery pack, ensure that the
safety catch is firmly closed.

CONNECTING TO A CIGARETTE LIGHTER SOCKET
To connect the transceiver to the cigarette lighter socket
in your vehicle, use an optional PG-3J Cigarette Lighter
cable.
When the PG-3J is connected to the cigarette lighter
plug, the transceiver automatically starts charging the
PB-43N Ni-MH battery pack.  While you operate the
transceiver, it charges the PB-43N Ni-MH battery pack
in the background.
To connect with an external 24 V power source via a DC-DC
converter, only use the optional PG-3J Cigarette Lighter cable.
Using the PG-2W DC cable in this situation may cause a fire.

Note:
uDo not use the PG-2W to connect a vehicle battery (12 V)
directly.  Extensive voltage could result in damaging the
transceiver.
uIf the input voltage exceeds approximately 16.5 V, warning beepssound and ÒDC ERRÓ appears.

CONNECTING TO A REGULATED POWER SUPPLY
To connect the transceiver to an appropriate regulated
DC power supply, use an optional PG-2W DC cable.
1Confirm that the power of both the transceiver and
the DC power supply is OFF.
2Connect the optional PG-2W DC cable to the DC
power supply; the red lead to the positive (+)
terminal, and the black lead to the negative (Ð)
terminal.
3Connect the barrel plug on the DC cable to the
DC IN jack of the transceiver.
While a DC power supply is connected with the DC IN
jack, the transceiver automatically initiates charging the
PB-43N Ni-MH battery pack.
Note:
uIf the DC power supply voltage is below 12.0 V DC, you may not
be able to charge the PB-43N Ni-MH battery pack.
uThe supply voltage must be between 12.0 V and 16.0 V to
prevent damaging the transceiver.  If the input voltage exceeds
approximately 16.5 V, warning beeps sound and ÒDC ERRÓ
appears.  Remove the DC IN jack plug immediately.
uIf the DC power supply voltage is above 14.5 V DC and ÒÓ
(High Power) is selected, the ÒÓ icon blinks and the output
power is gradually reduced to ÒÓ level (Medium Power){page 95}.

FIRST QSO
Are you ready to give your transceiver a quick try?
Reading this chapter should get your voice on the air
right away.  The instructions below are intended only for
a quick guide.  If you encounter problems or there is
something you would like to know more, read the
detailed explanations given later in this manual.
1Press and hold [  ] (POWER) briefly to switch the
transceiver power ON (TH-K2AT/ E/ ET example
shown below). 
						

							11
¥ A high pitched double beep sounds and a Power-ON
message appears momentarily.  The various indicators
and the current operating frequency appear on the LCD.
¥ The transceiver stores the current parameters when it
is turned OFF and automatically recalls these
parameters the next time you turn the transceiver ON.
2Turn the VOL control clockwise, to the 11 oÕclock
position.
3Turn the Tuning control to select a reception
frequency.

• You may further turn the VOL control to adjust the
volume level of the signal.
4To transmit, hold the transceiver approximately 5 cm
(2 inches) from your mouth.
5Press and hold [PTT], then speak in your normal
tone of voice.
6Release [PTT] to receive.
7Repeat steps 4, 5 and 6 to continue communication.
