Radios

Your wireless handheld portable transceiver contains a low power transmitter.
When the Talk button is pushed, it sends out radio frequency (RF) signals. 
The device is authorized to operate at a duty factor not to exceed 50%. 
In August 1996, the Federal Communications Commissions (FCC) adopted 
RF exposure guidelines with safety levels for handheld wireless devices. 

Important:
FCC RF Exposure Requirements: For body-worn operation, this radio has 
been tested and meets the FCC RF exposure guidelines when used with Cobra

®

accessories supplied or designated for this product. Use of other accessories 
may not ensure compliance with FCC RF exposure guidelines. Use only the
supplied antenna. Unauthorized antennas, modifications, or attachments 
could damage the transmitter and may violate FCC regulations. 

Normal Position: 
Hold the transmitter approximately two (2) inches from your face and 
speak in a normal voice, with the antenna pointed up and away.

This device complies with part 15 of the FCC Rules. Operation is subject 
to the following two (2) conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

FCC Warnings: Replacement or substitution of transistors, regular diodes or
other parts of a unique nature, with parts other than those recommended by
Cobra

®

may cause a violation of the technical regulations of part 95 of the FCC

rules, or violation of type acceptance requirements of part 2 of the rules.
