Notices to the User ◆ Government law prohibits the operation of unlicensed radio transmitters within the territories under government control. ◆ Illegal operation is punishable by fine and/or imprisonment. ◆ Refer service to qualified technicians only. Safety: It is important that the operator is aware of, and understands, hazards common to the operation of any transceiver. Precautions • • • • • • • • • • • Do not charge the transceiver and battery pack when they are wet.
Turn the transceiver power off in the following locations: • In explosive atmospheres (inflammable gas, dust particles, metallic powders, grain powders, etc.). • While taking on fuel or while parked at gasoline service stations. • Near explosives or blasting sites. • In aircraft. (Any use of the transceiver must follow the instructions and regulations provided by the airline crew.
Information concerning the battery pack: The battery pack includes flammable objects such as organic solvent. Mishandling may cause the battery to rupture producing flames or extreme heat, deteriorate, or cause other forms of damage to the battery. Please observe the following prohibitive matters. • • • • • • Do not disassemble or reconstruct the battery! The battery pack has a safety function and protection circuit to avoid danger.
• • • • • • • Use only the specified charger and observe charging requirements! If the battery is charged in unspecified conditions (under high temperature over the regulated value, excessive high voltage or current over regulated value, or with a remodeled charger), it may overcharge or an abnormal chemical reaction may occur. The battery may generate heat or smoke, rupture, or burst into flame.
• Do not touch a ruptured and leaking battery! If the electrolyte liquid from the battery gets into your eyes, wash your eyes with fresh water as soon as possible, without rubbing your eyes. Go to the hospital immediately. If left untreated, it may cause eye problems. • Do not charge the battery for longer than the specified time! If the battery pack has not finished charging even after the regulated time has passed, stop it. The battery may generate heat or smoke, rupture, or burst into flame.

PREPARATION Charging the Battery Pack The battery pack is not charged at the factory; charge it before use. Average battery pack life (calculated using 5% transmit time, 5% receive time, and 90% standby time) is 15 hours. Note: ◆ The ambient temperature should be between 32°F and 104°F (0°C and 40°C) while charging is in progress. Charging outside this range may not fully charge the battery.
3 When charging is complete, the LED indicator turns off. • It takes approximately 4 hours to charge the battery pack. LED Indicator n Charging with the KSC-44CR Charger 1 2 3 Plug the AC adapter cable into the jack located on the bottom of the charger. Plug the AC adapter into an AC outlet. Slide a transceiver equipped with a battery pack into the charging slot of the charger. • • 4 Make sure the metal contacts of the transceiver mate securely with the charger terminals.
Replacing the Battery Pack Replace an expired battery pack with a newly purchased KNB-71L battery pack. ◆ Do not disassemble the battery pack. ◆ Be sure to follow local laws concerning the disposal of battery packs. 1 Pull back the battery pack latch, then remove the battery cover from the transceiver. • When using the belt clip {page 6}, be sure to remove it before removing the battery cover. 2 Lift the battery pack and its packing away from the transceiver.
4 Insert the connector of the new battery pack into the PCB terminal by pressing down on it. • Red cable (right side) Match the direction of the connector and insert it vertically. 5 Pull back the battery pack latch, then insert the battery pack into position. • Failure to pull back the battery pack latch will cause the battery pack to be misaligned. 6 Replace the battery cover over the battery pack. • Ensure that the battery pack latch locks the cover in place.
Installing the Belt Clip If necessary, attach the belt clip using the two supplied M3 x 6 mm screws (with washers). Note: If the belt clip is not installed, its mounting location may get hot during continuous transmission or when left sitting in a hot environment. 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.
ORIENTATION ① ② 3.5 mm phone jack Connect the earphone/ microphone plug to this jack. Micro USB jack (B Type) Connect a USB cable to this jack to charge the transceiver battery pack. PF-1 key Press or hold this key for 1 second to activate its programmable functions. The default settings are [Scan](press) and [Super Lock-P](hold). • For function descriptions and details on how to change the key functions, refer to “KEY ASSIGNMENT MODE” on page 18.
LED indicator Refer to the “LED Indicator Status” table on page 10. PF-2 key Press this key to toggle the function of the Up/Down keys between Volume Adjustment mode and Channel Select mode. Hold this key for 1 second to activate its programmable function. The default setting is [Monitor]. • • Press the PF-2 key to toggle the function of the Up/Down keys between Volume Adjustment mode and Channel Select mode.
BASIC OPERATIONS Power and Volume 1 Hold the Power switch for approximately 1 second to switch the transceiver power ON. • • A beep sounds and the LED indicator blinks blue a number of times as described in the “Battery Level Guide” table on page 10. To turn the power OFF, hold the Power switch for 2 seconds. 2 In Volume Adjustment mode, press the Up/Down keys to adjust the volume. • • Press the key programmed as [Squelch Off] to hear background noise.
◆ Even when setting the volume to 0, the transceiver will continue to emit beep sounds and channel announcements. ◆ Continuously transmitting when the transceiver becomes too hot will cause the output power to decrease and may eventually stop transmission. Stop transmitting for a while to allow the transceiver to cool down. ◆ You may sometimes hear noise during communications, depending on the caller’s transceiver.
VOICE OPERATED TRANSMISSION (VOX) VOX operation allows you to transmit hands-free. VOX can only be used if you are using a supported clip microphone with earphone/hanger. This function can be turned off for specific channels. To activate VOX and set the VOX Gain level, perform the following steps: 1 Connect the microphone with earphone/hanger to the transceiver. • The VOX function does not activate when a microphone with earphone/hanger is not connected to the accessory terminal of the transceiver.
CHANNEL SETUP MODE This transceiver allows you to reprogram each of the channels with different frequencies and QT (Quiet Talk)/ DQT (Digital Quiet Talk) settings. The table below lists the default channel settings.

Quiet Talk (QT)/ digital quiet talk (DQT) Quiet Talk (QT) and Digital Quiet Talk (DQT) are functions that reject undesired signals on your channel. You will hear a call only when you receive a signal that contains a matching QT tone or DQT code. If a call containing a different tone or code is received, squelch will not open and you will not hear the call. Likewise, when transmitting using QT or DQT, the receiving station must have a matching tone or code to hear your call.
