CAUTION

SAFETY INFORMATION

Your wireless hand-held portable transceiver contains a low power transmitter. When the PTT button is pushed (or the VOX mode is enabled) 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 hand-held wireless devices.

To maintain compliance with the FCC’ s RF exposure guidelines

Important:

hold the transmitter at least 1 inch (2.5 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 Audiovox supplied carry clip for this product and ensure that the antenna is at least 1 inch (2.5 centimeters) from your body when transmitting. Use only the supplied antenna. Do not use your transceiver with a damaged antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations.

Performance:

Your transceiver will only achieve its maximum operating range when communicating with other transceivers across open and flat areas or between elevated points. Normally occurring environmental factors such as buildings, trees, terrain and weather, or interference from other radio or electrical equipment, may have adverse effects on the transceiver’s effective range. These are not indicative of a fault condition.

Avoid placing the GMRS672 radio transceiver for prolonged periods of time in direct sunlight or temperatures below -4 F (-20 C) or above 140 F (60 C).

Powering the transceiver:

Your GMRS672 radio transceiver operates on three AAA Alkaline batteries. Alkaline batteries will provide slightly better performance than rechargeable batteries. Only Audiovox approved rechargeable batteries should be recharged in the radio transceiver using the charging accessories. This will ensure optimum performance for the GMRS672. Battery charging time is typically 16-20 hours for full charge.

Installing the batteries:

Press down with the thumb at the embossed arrow, slide the battery cover down and lift it away from the compartment. Insert three AAA batteries (alternate positive ends (+) toward the top of the transceiver, starting left-toright).

NOTES FOR GOOD COMMUNICATION

1 . The 22 channels of the GMRS672 are shared on a ‘take turns’

basis. This means other groups may be talking on any of the channels. A common code of ethics/courtesy is to switch to another vacant channel and not to attempt to talk over someone who is already using the channel you first selected.

2. The GMRS672 has been designed to maximize performance and improve transmission range in the field. To avoid interference, it is recommended that you do not use the units closer than 5 feet apart.

3. For best transmission results, always keep your mouth about 2-3 inches from the microphone (5) and speak slowly in a normal voice.

4. To increase battery life, use the SCAN feature sparingly. This feature will reduce operating time considerably.

This transceiver complies with FCC regulations for use in the United States of America. Use in other countries may be prohibited or restricted by local regulation. Please check with the local regulating agency before using this device outside the United States of America.
