R

DANGER! NEVER

 operate the 

transceiver near unshielded electrical 

blasting caps or in an explosive atmosphere. 

This could cause an explosion and death.

 

R

WARNING! NEVER

 use or charge Icom 

battery packs with non-Icom transceivers 

or non-Icom chargers. Only Icom battery 

packs are tested and approved for use with 

Icom transceivers or charged with Icom 

chargers. Using third-party or counterfeit 

battery packs or chargers may cause 

smoke, fire, or cause the battery to burst.

 

R

WARNING! 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. 

 

R

WARNING! NEVER

 operate or touch 

the transceiver with wet hands. This could 

cause an electric shock or damage the 

transceiver.

 

R

WARNING! NEVER 

operate the 

transceiver with earphones, a headset or 

other audio accessories at high volume 

levels. The continuous high volume 

operation may cause a ringing in your ears. 

If you experience the ringing, reduce a 

volume level or discontinue use.

CAUTION: DO NOT

 use or leave 

the transceiver in excessively dusty 

environments. This could damage the 

transceiver.

CAUTION: DO NOT

 short the terminals of 

the battery pack. Shorting may occur if the 

terminals touch metal objects such as a 

key, so be careful when placing the battery 

packs (or the transceiver) in bags, and so 

on. Carry them so that shorting cannot 

occur with metal objects. Shorting may 

damage not only the battery pack, but also 

the transceiver.

CAUTION: DO NOT 

change the internal 

settings of the equipment. This may reduce 

equipment performance and/or cause 

extensive and expensive damage to the 

equipment. 

The equipment warranty does not cover 

any problems caused by unauthorized 

internal adjustments.

CAUTION: DO NOT

 operate the 

transceiver unless the rear cover and the 

connector covers are securely attached to 

the transceiver and that the battery pack 

are dry before attachment. 

Exposing the inside of the transceiver to 

dust or water will result in serious damage 

to the transceiver.

CAUTION: DO NOT

 operate the 

transceiver while driving a vehicle. Safe 

driving requires your full attention— 

anything less may result in an accident.

CAUTION: DO NOT

 use harsh solvents 

such as Benzine or alcohol when cleaning. 

This could damage the equipment 

surfaces. If the surface becomes dusty or 

dirty, wipe it clean with a soft, dry cloth.

CAUTION: DO NOT

 use the non-specified-

microphone. Other microphones have 

different pin assignments and may damage 

the transceiver.

CAUTION:

 Confirm that all connectors and 

jacks are dry and clean before attachment. 

Exposing them to dust or water will result in 

serious damage to the transceiver.
