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.
INSTALLING THE BATTERY PACK
Note:
Because the battery pack is provided uncharged, you must charge the battery pack before using it with the transceiver.
Match the guides of the battery pack with the corresponding grooves on the upper rear of the transceiver, then firmly press the battery case to lock it in place.
To remove the battery pack, lift the release lever to unlock the battery pack. Lift the battery pack away from the transceiver.
INSTALLING ALKALINE BATTERIES
1To open the optional KBP-9 battery case lid, press the release lever on the top of the battery case, then pull the cover up.
C A
B
2Insert (or remove) six AAA (LR03) Alkaline batteries.
•When removing the Alkaline batteries from the battery case, pull up on the batteries from the positive (+) terminal.
•Be sure to match the battery polarities with those marked in the bottom of the battery case.
3Align the two tabs at the bottom of battery case, then close the cover until the locking tabs on top click.
4To install the battery case onto (or remove it from) the transceiver, follow “INSTALLING THE BATTERY PACK”.
Note:
Do not use Manganese batteries or Rechargeable batteries in place of Alkaline batteries.
Remove all batteries from the case when it is not expected to be in use for several months.
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.
3-1
INSTALLING THE BELT CLIP
If desired, you can install the supplied belt clip to the transceiver.
Attach the belt clip firmly using the two supplied M3 x 6 mm binding screws.
Note
Be careful not to pinch your fingers into the belt clip.
CAUTION |
• Do not use glue which is designed to prevent screw |
loosening when installing the belt clip, as it may cause |
damage to the transceiver. Acrylic ester, which is |
contained in these glues, may crack the transceiver’s |
back panel. |
INSTALLING THE HAND STRAP
If desired, you can install the commercially available strap with sufficient strength using the holes of the transceiver.
Note
If the strap is thick and does not pass through the holes, install the strap using the holes of the supplied belt clip.
CHARGING THE BATTERY PACK
For charging the battery pack with the supplied battery charger
The battery pack can be charged after it has been installed onto the transceiver. (The battery pack is provided uncharged for safety purposes.)
1Confirm that the transceiver power is OFF.
•While charging the battery pack, leave the transceiver power OFF.
2Insert the charger plug into the DC IN jack of the transceiver.
DC IN jack
TH-D74A
TH-D74E
3Plug the charger into an AC wall outlet.
•Charging starts and “Charging” appears on the display.
•“Charging” disappears when charging is completed.
•The backlight is ON when pressing any key while charging.
•“Charging” does not appear when charging with the optional rapid battery charger.
4It takes approximately 3.5 hours to charge an empty KNB-75L Li-ion battery pack. After 3.5 hours, remove the charger plug from the transceiver DC IN jack.
5Unplug 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.
Do not expose the charger to dripping or splashing conditions.
No objects filled with liquids, such as vases, shall be placed on the AC adapter or charger.
Do not place the charger into the liquids.
Unplug the charger as soon as possible after the charging period is over.
The charger plug for an AC wall outlet should be used to disconnect an AC adapter from an AC outlet, and the charger plug must remain readily operable.
After the battery pack is charged, do not unplug and plug the charger into the AC outlet again. Unplugging the charger will reset the charging timer and the battery pack will be charged again. This could result in over-charging.
When the battery is installed on the transceiver and you are using an optional rapid battery charger, do not charge the battery from the DC IN jack. Charging the battery from the DC IN jack may result in overcharging the battery which can result in the shortening of the battery life cycle.
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 several 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 KNB-75L battery pack.
The provided charger is designed to charge only the KNB-75L 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 battery pack, ensure that the release lever is firmly closed.
Attention should be drawn to the environmental aspects of battery disposal.
It takes approximately 3 hours to charge the KNB-75L with the optional rapid battery charger.
3-2
For charging the battery pack with the optional rapid battery charger
Note:
Insert the battery pack only in the rapid battery charger to charge a battery pack that has been in storage for a long time.
If the battery pack is completely depleted while using the transceiver, remove the battery pack from the transceiver and insert the battery pack in the rapid battery charger.
Charger Error
•While charging, if a problem is detected in the battery, “Charge Error !!” appears on the display.
•The following conditions create charging errors:
•A short in the battery is detected.
•Overvoltage in the battery is detected.
•When a charge error occurs, no key other than [ 
] will function.
BATTERY LIFE
Before you operate the transceiver outside using a battery pack, it is important to know how long the battery pack will last. The operating times listed in the table below are measured under the following cyclic conditions:
TX: 6 seconds, RX: 6 seconds, Stand-by: 48 seconds
We recommend you carry extra battery packs with you, in case the battery pack becomes depleted.

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 battery pack. While you operate the transceiver, it charges the battery pack in the background.
Note:
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.

7 OPERATING THROUGH FM REPEATERS
Repeaters are often installed and maintained by radio clubs, sometimes with the cooperation of local businesses involved in the communications industry.
Compared to simplex communication, you can usually transmit over much greater distances by using a repeater. Repeaters are typically 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 considerable distances.
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
REPEATER ACCESS
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 in order to gain access to the repeater. For details, consult your local repeater reference.
Selecting an Offset Frequency
The offset frequency is the value which the transmit frequency will be offset from the receive frequency. The default offset frequency on the 144 MHz band is 600 kHz for all type versions. The default on the 430/440 MHz band is 5 MHz.
1Select your desired band A or B.
2Access Menu No. 140.
•The selectable range is from 00.00 MHz to 29.95 MHz, in steps of 50 kHz.
Note:
After changing the offset frequency, the new offset frequency will also be used by Automatic Repeater Offset.
Automatic Repeater Offset
This function automatically selects an offset direction and activates the Tone function, according to the frequency that you have selected. To obtain an up-to-date band plan for repeater offset direction, contact your national Amateur Radio association.

TRANSMITTING A 1750 Hz TONE
Most repeaters in Europe require that a transceiver transmit a 1750 Hz tone. On a TH-D74E, simply pressing [CALL] will transmit this tone. It is also possible to program [1750Hz] on the front panel as a [CALL] key for transmitting the 1750 Hz tone.
1 Access Menu No. 142.
2 Set to [1750Hz].
Some repeaters in Europe must receive continuous signals for a certain period of time, following a 1750 Hz tone. This transceiver is also capable of remaining in the transmit mode for 2 seconds after transmitting a 1750 Hz tone.
1 Access Menu No. 143.
2 Set to [On].
Note:
While remaining in the transmit mode, the transceiver does not continuously transmit a 1750 Hz tone.
Selecting an Offset Direction
The offset direction allows your transmit frequency to be higher (+) or lower (–) than the receive frequency.
1Select your desired band (A or B).
2Press [F], [REV] to select an offset direction.
•Each time you press [F], [REV], the offset direction changes as follows:
Simplex operation + – Simplex operation
•If you are using a TH-D74E, when operating on the 430
MHz band, the offset direction changes as follows:
Simplex operation + – = (–7.6 MHz) Simplex operation
If the offset transmit frequency falls outside the allowable range, transmitting is inhibited. Use one of the following methods to bring the transmit frequency within the band limits:
•Move the receive frequency further inside the band.
•Change the offset direction.
Note:
While using an odd-split memory channel or transmitting, you cannot change the offset direction.
REVERSE FUNCTION
After setting a separate receive and transmit frequency, you can exchange these frequencies using the Reverse function.
This allows you to manually check the strength of signals you receive directly from other stations, while using a repeater. If the station’s signal is strong, move to a simplex frequency to continue the contact and free up the repeater.
1Press [REV] to turn the Reverse function [On] or [Off].
•When the Reverse function is On, the < 
> icon will appear on the display.
Note:
If the transmit frequency is outside the allowable transmit frequency range when using Reverse, pressing [PTT] will cause an error tone to sound and transmission will be inhibited.
If the receive frequency is outside the receive frequency range when using Reverse, an error tone will sound and Reverse will not operate.
The ARO (Automatic Repeater Offset) will not function when
Reverse is ON.
You cannot switch Reverse On or Off while transmitting.

8 MEMORY CHANNEL
In Memory channels, you can store frequencies and related data that you often use. Then you need not reprogram
the data every time. You can quickly recall a programmed channel by simple operation. A total of 1101 Memory channels (1000 Memory channels, 100 Program scan memory, and Priority scan memory) are available.
SIMPLEX & REPEATER OR ODD-SPLIT MEMORY CHANNEL?
You can use each memory channel as a simplex & repeater channel or as 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
The data listed below can be stored in each Memory channel:

Note:
Adjust the squelch level before using scan. Selecting a squelch level too low could cause scan to stop immediately.
While using CTCSS or DCS, scan stops for any signal received; however, scan will immediately resume if the received signal does not contain the same CTCSS tone or DCS code that you selected.
Pressing and holding [PTT] causes scan to temporarily stop if it is functioning on a non TX band.
SELECTING A SCAN RESUME METHOD
The transceiver stops scanning at a frequency or Memory channel on which a signal is detected. It then continues scanning according to which resume mode you have selected. You can choose one of the following modes.
Time-Operated mode
Scan will stop temporarily once the squelch opens. Scan will resume 5 seconds later (default setting) regardless of the squelch status.
Carrier-Operated mode
Scan will stop temporarily once the squelch opens. Scan will resume if the squelch remains closed for more than 2 seconds (default setting).
Seek mode
Scan will complete once the squelch opens, and it will not resume.
1Access Menu No. 130.
• In digital (DV/DR mode), access Menu No. 131.
2Set the Scan Resume mode to [Time] (Time-Operated), [Carrier] (Carrier-Operated) or [Seek] (Seek).
Time-Operate Resume Time
Set the hold time for the Time-Operate scan method.
When a signal is received, scan will pause at that frequency for the duration of the hold time you set. When the set time elapses, scan will resume (even if the signal is still being received).
1Access Menu No. 132.
2Set the resume time to 1 ~ 10 sec.
Carrier-Operated Resume Time
Set the hold time for the Carrier-Operate scan method.
When a signal is received, scan will pause at that frequency. When the signal stops, scan will resume after the duration of the hold time you set.
1 Access Menu No. 133.
2 Set the resume time to 1 ~ 10 sec.
BAND SCAN
Band scan monitors all frequency range that is stored in
Menu No. 100 (Programmable VFO), using the current frequency step size.
1Select your desired operation band and frequency.
2Press [VFO] (1s).
Band scan appears and scan starts at the current frequency.
•The 1 MHz decimal point blinks while scanning is in progress.
Note:
When starting a scan within the frequency range of the registered program scan memory, it is the program scan.
3 To quit band scan, press [VFO].

PROGRAM SCAN
Program scan is to scan within the range between the lower limit frequency and upper limit frequency registered to program scan memory. There are 50 program scan memory from L0/U0 to L49/U49.
Setting Scan Limits
1Select the frequency, mode, etc. to register.
2Press [VFO].
3Press [F], [MR].
Memory channel registration screen appears on the display.
4To set a lower limit frequency, select channel [L0]. To set an upper limit frequency, select channel [U0].
5Press [ENT].
The frequency is registered in the memory channel. The picture below shows an example when a lower limit frequency is set in L0.
6Register the corresponding upper limit or lower limit frequency.
Repeat steps 3 to 6. Memory channels from L1/U1 to L49/ U49 can be registered similarly.
Using Program Scan
1Adjust the frequency within the range of the program scan memory.
•When the VFO frequency is within the registered frequency range in the program scan memory,
[Program No. 0] appears under the frequency display.
2Press [VFO] (1s).
The program scan starts and the dot of the 1 MHz digit flashes.
3To quit program scan, press [VFO].
Note:
When a frequency range registered in the program scan memory is duplicated, the range assigned to a smaller program scan memory number will be applied.
Band scan is activated if [VFO] is pressed for more than 1 second outside the program scan memory frequency range.
MHz SCAN
MHz scan monitors a 1 MHz segment of the band, using the current frequency step size. The current 1 MHz digit determines the limits of the scan. For example, if the current frequency is 145.400 MHz, then the scan range would be from 145.000 MHz to 145.995 MHz (the exact upper limit depends on the current frequency step size).
1Select your desired band.
2Press [VFO].
3 Press [ ]/[
] or rotate the [ENC] control to select a frequency within your desired 1 MHz range.
4Press [MHz] (1s) to start scanning.
•Scan starts at the current frequency.
•The 1 MHz decimal point blinks while scanning is in progress.
•To reverse the scan direction, turn the [ENC]
control clockwise <or press [
]> (upward scan) or counterclockwise <or press [
]> (downward scan).
5To quit MHz Scan, press [MHz].
MEMORY SCAN
Use memory scan to monitor all Memory channels programmed with frequency data.
1Press [MR] (1s).
Scan starts at the current memory channel.
2 To quit memory scan, press [MR].
Note:
At least 2 Memory channels must contain data and must not be locked out of scan.
Program scan memory and priority channel will be excluded from the memory scan.
If the memory recall method is set to [Current Band], the memory channel of the same frequency band as the current memory channel will be scanned. The other memory channel will be skipped.
