Operational Cautions

Exposure to high volume sound levels may cause temporary or permanent 

damage to your hearing. Although there is no single volume setting that is 

appropriate for everyone, you should always use your radio with the volume set 

at low level and avoid prolonged exposure to high volume sound levels.
1. Set the volume control in a low position and use as low a volume as 

possible.

2. Avoid turning up the volume to block out noisy surroundings. Whenever 

possible, use your radio in a quiet environment with low background noise.

3. Limit the amount of time you use headsets or earpiece at high volume 

levels.

4. When using the radio without a headset or earpiece, do not place the radio’s 

speaker directly against your ear.

5. Observe all signs and instructions that require an electrical device or RF 

radio product to be switched off in designated areas, such as gas/refueling 

stations, hospitals, blasting areas, potentially explosive atmospheres, or 

aircraft.

6. If you experience a skin irritation after using this product, discontinue use 

and seek medical attention.

7. If the product or charger: overheats; has a damaged cord or plug; has been 

dropped or damaged; has been dropped into water, disconnect any charger 

from its power supply, discontinue use of the product.

Electromagnetic Interference

Nearly every electronic device is susceptible to electromagnetic interference 

(EMI) if inadequately shielded, designed, or otherwise configured for 

electromagnetic compatibility. Turn off your radio in any facility where posted 

notices instruct you to do so. These facilities may include hospitals or health 

care facilities that may be using equipment that is sensitive to external RF 

energy.

 When instructed to do so, turn off your radios when on board an aircraft. Any 

use of a RF device must be in accordance with applicable laws, regulations 

and airline crew instructions.

 Some radios may interfere with some hearing aids. In the event of such 

interference, you may want to consult your hearing aid manufacturer or 

physician to discuss alternatives.

 If you use any other personal medical device, consult the manufacturer of 

your device to determine if it is adequately shielded from RF energy. Your 

doctor or physician may be able to assist you in obtaining this information.
