SAFETY TRAINING INFORMATION

DO NOT transmit more than 50% of total radio use time (50% duty cycle). Transmitting for more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. This radio is transmitting when- ever Tx is indicated in the lower right corner of the display. Pressing the PTT switch on the side usually causes the radio to transmit.

DO NOT use any accessories not specifically authorized by the E.F. Johnson Company for use with this radio such as batteries, speaker- microphones, belt clips, and antennas. The use of unauthorized accessories can cause FCC RF exposure compliance requirements to be exceeded.

ALWAYS keep the antenna and radio at least 2.54 cm (1.0 inch) away from your body when transmitting to ensure FCC RF exposure compliance requirements are not exceeded. The best transmission quality results when the antenna is at least 5 cm (2 inches) away from your mouth and angled slightly to one side.

This unit has not been tested for FCC RF exposure compliance in applica- tions where the unit is transmitting while body worn on the belt clip. This product is not intended for use in applications where transmissions are required while the unit is body worn with the use of the belt clip.

NOTE: The preceding information is provided to make you aware of RF expo- sure and what to do to ensure that this radio is operated within FCC RF exposure limits.

Electromagnetic Interference/Usage Compatibility

This device complies with Part 15 of the FCC rules. Operation is subject to the condition that this device does not cause harmful interference. In addition, changes or modification to this equipment not expressly approved by the E.F. Johnson Company could void the user’s authority to operate this equipment (FCC Rules, 47CFR Part 15.19).

DO NOT operate it in areas that are sensitive to RF energy such as aircraft, hospitals, blasting sites, and fuel storage sites. Areas with potentially flammable atmospheres are usually, but not always, clearly posted. These may include gas stations, fuel and chemical storage and transfer stations, below deck on boats, and areas where the air contains flammable chemicals or particles such as grain dust or metal powders.

Dispose of the nickel metal-hydride battery used by this radio in accordance with local regulations. DO NOT dispose of it in fire because it can explode. Also, do not short the terminals because it may become very hot.
