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 “I

” {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.

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.

6

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.

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.

PERATION

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.

VOL

ENC.

• 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.

17

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.

18

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).

19

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 Tuning control.

20

■

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

SELECTIVE CALL

CTCSS

AND

DCS

You may sometimes want to hear calls from only specific persons or groups. In this case, use the

Selective Call. This transceiver is equipped with

CTCSS (Continuous Tone Coded Squelch System) and

DCS (Digital Coded Squelch). These Selective Calls allow you to ignore (not hear) unwanted calls from other persons who are using the same frequency. The transceiver unmutes only when it receives a signal having the same CTCSS tone or DCS code.

Note: CTCSS and DCS do not cause your conversation to be private or scrambled. It only relieves you from listening to unwanted conversations.

CTCSS

A CTCSS tone is a sub-audible tone and is selectable from among the 42 tone frequencies listed in the table on the page 71. The list includes 37 EIA standard tones and 5 non-standard tones.

ATTERY

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.

110

M

ICROPROCESSOR

R

ESET

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.

111

Performing Reset

There are 2 ways to enter the Reset Mode selection.

However, the transceiver’s Lock function must be turned

OFF {page 88}.

When the transceiver is turned OFF:

■

Full reset

1 Press [F]+[ ] (POWER).

• All indicators are lit.

2 Release [F].

• The full reset confirmation message, “FL.RST?”, appears.

3 Press [F] to proceed.


• Press any key other than [F], [LAMP] and

[MONI/SQL] to exit the Reset Mode.

4 Press [F] to reset the transceiver.

112

■

VFO reset

1 Press [VFO]+[ ] (POWER).

2 Release [VFO].

• The VFO reset confirmation message, “VF.RST?”, appears.

3 Press [VFO] to proceed.


• Press any key other than [VFO], [LAMP] and


4 Press [VFO] to reset the transceiver.

113

Reset using the Menu

1 Press [MENU].


(RESET).

3 Press [MENU].

4 Turn the Tuning control to select the Reset Mode,

“FULL” or “VFO”.

5 Press [MENU] to select the Reset Mode.


• Press any key other than [MENU], [LAMP] and


6 Press [MENU] to reset the transceiver.

PERATION

N

OTICES

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 “SPECIFICATIONS” {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

“DC ERR” 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 “ ” power.

Receiving Signals in Cities

When you receive signals in cities, the receiver’s 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.

115

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.

“ ” 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 “ON”.

116

ROUBLESHOOTING

The problems described in the following tables are commonly encountered operational malfunctions.

These types of difficulties are usually caused by improper hook-up, accidental incorrect control settings, or operator error due to incomplete programming.

These problems are usually not caused by circuit failure. Please review these tables and the appropriate section(s) of this instruction manual before assuming your transceiver is defective.

Note: Placing powered PC peripherals near this transceiver may cause noise in the transceiver.
