PREPARATION

INSTALLING THE PB-43N Ni-MH BATTERY PACK

Note: Because the battery pack is provided uncharged, you must charge the battery pack before using it with the transceiver. To charge the battery pack, refer to “CHARGING THE PB-43N Ni-MH BATTERY PACK (Other than TH-K2AT K2/ M2, TH-K4AT M2)” {page 6}.

1 Unlock (open) the safety catch located at the bottom

of the battery pack.

2 Match the guides of the battery pack with the

corresponding grooves on the upper rear of the transceiver, then firmly press the battery pack to lock it in place.

3 Flip the safety catch into place to prevent

accidentally pressing the release latch and removing the battery pack.

4 To remove the battery pack, lift the safety catch, then

press the release latch to unlock the battery pack. Lift the battery pack away from the transceiver.

INSTALLING ALKALINE BATTERIES

1 To open the BT-14 battery case lid, insert your thumb

or finger into the hole on the top of the battery case, then pull the cover up.

2 Insert (or remove) six AA (LR6) Alkaline batteries.

• Be sure to match the battery polarities with those marked in the bottom of the battery case.

3 Align the two tabs at the bottom of battery case, then

close the cover until the locking tabs on top click.

4 To install the battery case onto (or remove it from)

the transceiver, follow steps 1 to 3 of “INSTALLING THE PB-43N Ni-MH BATTER Y PACK” {page 1}.

Note:

◆ Do not use Manganese batteries or Ni-Cd batteries in place of Alkaline batteries.

◆ Always replace all batteries at the same time. Mixing old and new batteries or mixing types (such as Alkaline with zinc carbon) will reduce overall performance and could cause leakage or rupture.

◆ Remove all batteries from the case when it is not expected to be in use for several months.

◆ The voltage of new Alkaline batteries varies slightly, depending on the manufacturer. Thus, the high battery power indicator may not appear even though new Alkaline batteries are installed {page 83}.

◆ To lift the battery pack safety catch, use a piece of hardened plastic or metal, such as a screwdriver, that is no more than 6 mm wide and 1 mm thick. It is imperative that you place the implement under only the lip of the safety catch so that you do not damage the release latch.

INSTALLING THE ANTENNA

Hold the supplied antenna by its base, then screw it into the connector on the top panel of the transceiver until secure.

ATTACHING THE HAND STRAP (OTHER THAN TH-K2AT K/ K2)

If desired, you can attach the supplied hand strap to the transceiver.

Strap

INSTALLING THE BELT CLIP

If desired, you can install the supplied belt clip to the transceiver.

1 Loosely insert the two supplied screws into the holes

on the back panel of the transceiver.

2 Slide the belt hook into position, under the screws. 3 Tighten the screws until secure.

Note: When the belt hook is not attached to the transceiver, remove

the screws from the transceiver to avoid scratching other materials.

CHARGING THE PB-43N Ni-MH BATTERY PACK (OTHER THAN TH-K2AT K2/ M2, TH-K4AT M2)

The Ni-MH battery pack can be charged after it has been installed onto the transceiver. (The battery pack is provided uncharged for safety purposes.)

1 Confirm that the transceiver power is OFF.

• While charging the battery pack, leave the transceiver power OFF .

2 Insert the charger plug into the DC IN jack of the

transceiver.

DC IN jack

3 Plug the charger into an AC wall outlet.

• Charging starts.

4 It takes approximately 12 hours to charge an empty

PB-43N Ni-MH battery pack. After 12 hours, remove the charger plug from the transceiver DC IN jack.

5 Unplug the charger from the AC wall outlet.

Note:

◆ Never leave the battery pack in direct sunlight.

◆ The transceiver becomes warm while charging the battery pack.

◆ While 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.

◆ Before recharging the battery pack, use the battery pack until the transceiver stops receiving.

◆ Do not plug the charger into the DC IN jack for more than 24 hours.

◆ Unplug the charger as soon as possible after the charging period is over.

◆ After 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.

◆ If 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.

◆ If 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.

◆ If 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.

◆ Exceeding the specified charge period shortens the useful life of the PB-43N Ni-MH battery pack.

◆ The 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.

◆ Do not transmit while charging.

◆ When not in use, store the battery pack in a cool and dry place.

◆ Before 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.

the DC power supply is OFF.

2 Connect 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 (–) terminal.

Fuses (4 A)

3 Connect 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:

◆ If 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.

◆ The 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 “DC ERR” appears. Remove the DC IN jack plug immediately.

◆ If the DC power supply voltage is above 14.5 V DC and “ ”

(High Power) is selected, the “ ” icon blinks and the output power is gradually reduced to “ ” level (Medium Power) {page 95}.
