NOTICES TO THE USER

◆ Government law prohibits the operation of unlicensed transmitters within the territories under

government control.

◆ Illegal operation is punishable by ﬁ ne and/or imprisonment.

◆ Refer service to qualiﬁ ed technicians only.

SAFETY: It is important that the operator is aware of, and understands, hazards

common to the operation of any transceiver.

◆ EXPLOSIVE ATMOSPHERES (GASES, DUST, FUMES, etc.)

Turn OFF your transceiver while taking on fuel or while parked in gasoline service stations. Do not carry

spare fuel containers in the trunk of your vehicle if your transceiver is mounted in the trunk area.

◆ INJURY FROM RADIO FREQUENCY TRANSMISSIONS

Do not operate your transceiver when somebody is either standing near to or touching the

antenna, to avoid the possibility of radio frequency burns or related physical injury.

◆ DYNAMITE BLASTING CAPS

Operating the transceiver within 500 feet (150 m) of dynamite blasting caps may cause them

to explode. Turn OFF your transceiver when in an area where blasting is in progress, or where

“TURN OFF TWO-WAY RADIO” signs have been posted. If you are transporting blasting caps

in your vehicle, make sure they are carried in a closed metal box with a padded interior. Do not

transmit while the caps are being placed into or removed from the container.
