PRECAUTIONS

RWARNING RF EXPOSURE! This device emits Radio Frequency (RF) energy. Caution should be observed when operating this device. If you have any questions regarding RF exposure and safety standards please refer to the Federal Communications Commission Ofce of Engineering and Technologys report on Evaluating Compliance with FCC Guidelines for Human Radio Frequency Electromagnetic Fields (OET Bulletin 65) RWARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm away from the lips and the transceiver is vertical. RWARNING! NEVER operate the transceiver with a earphone, headphones or other audio accessories at high volume levels. Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the volume level or discontinue use. RWARNING! NEVER operate the transceiver while
driving a vehicle. Safe driving requires your full attention anything less may result in an accident.
NEVER expose the transceiver to rain, snow or any liquids.
The transceiver may be damaged.
NEVER operate or touch the transceiver with wet hands.
This may result in an electric shock or damage the transceiver.
DO NOT operate the transceiver near unshielded electrical blasting caps or in an explosive atmosphere. DO NOT push the PTT when not actually desiring to transmit. BE CAREFUL! The transceiver will become hot when operating it continuously for long periods.
AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below 20C or above +60C.
Place the unit in a secure place to avoid inadvertent use by children.
AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they can damage the transceivers surfaces.
NEVER connect the transceiver to a power source of more
than 16 V DC. This will ruin the transceiver.
NEVER connect the transceiver to a power source using reverse polarity. This will ruin the transceiver.

I Resetting

The function display may occasionally display erroneous information (e.g. when rst applying power). This may be caused externally by static electricity or by other factors. If this problem occurs, turn power OFF. After waiting a few seconds, turn power ON again. If the problem persists, perform either or both procedures below.

D All reset

q Push and hold [PWR] for 1 sec. to turn power OFF. w While pushing and holding [VFO], [MR] and [BAND], then turn power ON to reset the CPU.
ALL RESET appears when resetting the CPU (See the illustration below).

D Partial reset

q Push and hold [PWR] for 1 sec. to turn power OFF. w While pushing and holding [VFO], then turn power ON to partially reset the transceiver. [NOTE]: No message appears on the display after the partial reset is done.

All reset

Reset the CPU before operating the transceiver for the rst time, or if the internal CPU malfunctions, to clear and return all programmed contents to their default settings.

ALL RESET

Partial reset
If you want to initialize the operating conditions (VFO frequency, VFO settings, set mode contents) without clearing the memory contents, a partial reset function is available for the transceiver.
CAUTION: Resetting the CPU returns all programmed contents to their default settings.

TROUBLESHOOTING

POSSIBLE CAUSE
The batteries are exhausted. The battery polarity is reversed.
If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center.

PROBLEM

No power comes ON.

SOLUTION
