Safety & General Information
Important Information for Safe and Efficient Operation. Please read this information before
using your radio.

2. Changes or modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment.
3. Radio frequency signals transmitted may cause interference to hearing aids.
4. Turn off the radio when near medical equipment.
5. This product should not be used by people with pacemakers.
6. Do not use the radio when driving a vehicle or operating machinery.
7. Do not use the radio when on board aircraft.
8. Do not hold the antenna when transmitting.
9. Do not use the radio when the antenna has damaged.
10. Turn off the radio and remove the batteries if you are not going to use it for a long time.
Two-way Radio Operation
The device was tested for typical body-worn operations using the supplied belt-clip. To maintain compliance with FCC RF exposure requirements, body-worn operations are restricted to the supplied belt-clip. For hand-held operation, the radio should be held at least 1 inch (2.5cm)
from the user’s face. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements and
should be avoided. For more information about RF exposure, please visit the FCC web site at www.fcc.gov.
