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}.

BASIC OPERATION

VOL ENC.

Switching the Power ON/OFF

1 Press [ ] (POWER) briefly to switch the transceiver

power ON.

• A high pitched double beep sounds and a Power-ON message {page 92} appears briefly, followed by the frequency and other indicators.

2 To switch the transceiver OFF, press [ ] (POWER)

again.

• When you turn the transceiver OFF, a low pitched double beep sounds.

• The transceiver stores the current frequency and parameters when it is turned OFF and recalls these parameters the next time you turn the transceiver ON.

Adjusting the Volume

Turn the VOL control clockwise to increase the audio output level and counterclockwise to decrease the output level.

• If you are not receiving a signal, press and hold

[MONI/SQL] to unmute the speaker, then adjust the VOL control to a comfortable audio output level.

Adjusting the Squelch

The purpose of Squelch is to mute the speaker when no signals are present. With the squelch level correctly set, you will hear sound only while actually receiving signals. The higher the selected squelch level, the stronger the signals must be to receive.

The appropriate squelch level depends on the ambient RF noise conditions.

1 Press [F], [MONI/SQL].

• The current squelch level appears.

2 Turn the Tuning control to adjust the level.

• Select the level at which the background noise is just eliminated when no signal is present.

• The higher the level, the stronger the signals must be to receive.

• 6 different levels can be set. (0: Minimum ~ 5: Maximum; 2 is the default value)

3 Press any key other than [LAMP], [MONI/SQL] to

store the new setting and exit the squelch adjustment.

Transmitting

1 To transmit, hold the transceiver approximately 5 cm

(2 inches) from your mouth, then press and hold [PTT] and speak into the microphone in your normal tone of voice.

• The LED lights red and the bar-graph meter appears.

• If you press [PTT] while you are outside of the transmission coverage, a high pitched error beep sounds.

2 When you finish speaking, release [PTT].

Note: If you continuously transmit for longer than the time specified

in Menu No. 23 (default is 10 minutes) {page 94}, the internal timeout timer generates a warning beep and the transceiver stops transmitting. In this case, release [PTT] and let the transceiver cool down for a while, then press [PTT] again to resume transmission {page 116}.

■ Selecting an Output Power

Selecting a lower transmission power is the best way to reduce battery consumption, if communication is still reliable. You can configure different power levels for transmission {page 95}.

Press [F], [PTT] to cycle between “ ” (high), “ ” (medium), and “ ” (low).

Selecting a Frequency

■ VFO Mode

This is the basic mode for changing the operating frequency. Turn the Tuning control clockwise to increase the frequency and counterclockwise to decrease the frequency .

■ MHz Mode

If the desired operating frequency is far away from the current frequency, it is quicker to use the MHz Tuning Mode.

To adjust the MHz digit: 1 Press [F].

• The MHz digit blinks.

2 Turn the Tuning control to select the desired MHz

value.

3 After selecting the desired MHz value, press [F]

to exit the mode and return to normal VFO Mode.

4 Continue adjusting the frequency as necessary,

using the T uning control.

■ Direct Frequency Entry (TH-K2AT/ ET/ K4AT only)

In addition to turning the Tuning control, there is another way to select the frequency. When the desired frequency is far away from the current frequency , you can directly enter a frequency using the numeric keypad.

1 Press [VFO].

• You must be in the VFO Mode to make the direct

frequency entry.

2 Press [#].

3 Press the numeric keys ([0] to [9]) to enter your

desired frequency. [ ] allows you to complete the MHz digits entry.

• Pressing [#] fills all remaining digits (the digits you

did not enter) with 0 and completes the entry . For example, to select 145.000 MHz, press [1], [4], [5] and press [#] to complete the entry.

• If you want to revise the MHz digits only, leaving the

kHz digits as they are, press [VFO] in place of [#].

OPERATING THROUGH REPEATERS

Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. They generally operate at higher ERP (Effective Radiated Power) than a typical station. This combination of elevation and high ERP allows communications over much greater distances than communicating without using repeaters.

Most repeaters use a receive and transmit frequency pair with a standard or non-standard offset (odd-split). In addition, some repeaters must receive a tone from the transceiver to be accessed. For details, consult your local repeater reference.

TX: 144.725 MHz TX tone: 88.5 Hz RX: 145.325 MHz TX: 144.725 MHz

TX tone: 88.5 Hz RX: 145.325 MHz

OFFSET PROGRAMMING FLOW

Select a receive frequency.

Select an offset direction.

Select an offset frequency (only when programming odd-split repeater frequencies).

Activate the Tone function (if necessary).

Select a tone frequency (if necessary).

If you store all the above data in a memory channel, you will not need to reprogram the parameters every time. Refer to “MEMORY CHANNELS” {page 41}.

Programming an Offset

You must first select an amateur radio repeater downlink frequency as described in “Selecting an Offset Frequency” {page 33}.

■ Selecting an Offset Direction

Select whether the transmission frequency will be higher (+) or lower (–) than the reception frequency.

1 Press [MENU]. 2 Turn the Tuning control to select Menu No. 6

(SFT).

3 Press [MENU]. 4 Turn the Tuning control to select “+” or “–”.

• To program a –7.6 MHz offset (TH-K4E only), select “–7.6” instead.

5 Press [MENU] to store the setting or [PTT] to

cancel.

• “+” or “–” (or “ ”) appears above the frequency, indicating which offset direction is selected.

If the offset transmission frequency falls outside the allowable range, transmission is inhibited. In this case, adjust the reception frequency so that the transmission frequency is within the band limits.

Note: While using an odd-split memory channel or transmitting, you cannot change the offset direction.

■ Selecting an Offset Frequency

To access a repeater which requires an odd-split frequency pair, change the offset frequency from the default which is used by most repeaters. The default offset frequency on the 2 m band is 600 kHz (all TH-K2 models); the default on the 70 cm band is

5.0 MHz (TH-K4AT) or 1.6 MHz (TH-K4E).

1 Press [MENU]. 2 Turn the Tuning control to select Menu No. 8

(OFFSET).

3 Press [MENU].

4 Turn the Tuning control to select the appropriate

offset frequency.

REVERSE FUNCTION

The Reverse function exchanges a separate reception and transmission frequency. So, while using a repeater, you can manually check the strength of a signal that you receive directly from the other station. If the station’s signal is strong, both stations should move to a simplex frequency and free up the repeater.

To swap the transmission and reception frequencies: Press [F], [MENU] to switch the Reverse function ON

(or OFF).

• “R” appears when the function is ON.

Note: Y ou can turn the Reverse function ON when you are operating in Simplex Mode. However, it does not change the Transmission/ Reception frequency.

AUTOMATIC SIMPLEX CHECK (ASC)

While using a repeater, the ASC function periodically checks the strength of the signal you are receiving from the other station. If the station’s signal is strong enough to allow direct contact without a repeater, the “ ” indicator starts blinking.

• When the tone frequency is identified, a beep sounds and the identified frequency blinks.

4 Press [MENU] to program the identified frequency in

place of the current tone frequency.

• Press any key other than [MENU], [LAMP], and [MONI/SQL] if you do not want to program the identified frequency.

• Turn the Tuning control while the identified frequency is blinking to resume scanning.

Note: Some repeaters do not re-transmit the access tone in the downlink signal. In this case, check the other station’s uplink signal to detect the repeater access tone.

MEMORY CHANNELS

In memory channels, you can store frequencies and related data that you frequently use so that you do not need to reprogram that data every time. You can quickly recall a programmed channel through simple operation. A total of 100 memory channels (50 when using the Memory Name function) are available for storing frequencies, modes and other operating conditions.

NUMBER OF MEMORY CHANNELS

The transceiver must be configured to either 100 memory channels without using the Memory Name function or 50 memory channels with the Memory Name function (default).

To change the memory channel capacity:

[MENU], [LAMP], and [MONI/SQL] to cancel.

Note:

◆ If you change the memory channel capacity from 100 channels to 50 channels after having stored data in channels 50 to 99, all memory channel data in channels 50 to 99 will be erased.

◆ If you change the memory channel capacity from 50 channels to 100 channels after storing Memory names in those channels, all Memory name data will be erased.

SIMPLEX & REPEATER OR ODD-SPLIT MEMORY CHANNEL?

You can use each memory channel as a simplex & repeater channel or an odd-split channel. Store only one frequency to use as a simplex & repeater channel or two separate frequencies to use as an odd-split channel. Select either application for each channel depending on the operations you have in mind.

Simplex & repeater channels allow:

• Simplex frequency operation

• Repeater operation with a standard offset (if an offset direction is stored)

Odd-split channels allow:

• Repeater operation with a non-standard offset

Note: Not only you can store data in memory channels, but you can also overwrite existing data with new data.

The data listed below can be stored in each memory channel:
