To maintain compliance with the FCC’s RF guidelines, hold the transmitter at least
2 inches (5 centimeters) from your face and speak in a normal voice, with the antenna
pointed up and away. If you wear the handset on your body while using the headset
accessory, use only the Cobra®supplied belt clip for this product and ensure that the
antenna is at least 1 inch (2.5 centimeters) from your body while transmitting. If the
distance between the antenna and the body is LESS THAN 1.0" (2.5 cm), DO NOT USE
THIS DEVICE IN THE BODY WORN CONFIGURATION. Use only the supplied antenna.
Unauthorized antennas, modifications, or attachments could damage the transmitter
and may violate FCC regulations.

in a normal voice, with the antenna pointed up and away.
