Safety Information for microTALK® 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 Commission (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 five cm (two inches) from your face and speak in a normal voice, with the antenna pointed up and away.

Operation

Using Your Radio

For charging microTALK radio(s) in desktop charger:

1. Insert radio(s) into desktop charger as shown.

2. Insert round connector of 120-volt adapter into

jack on back of charger.

3. Plug 120-volt adapter into electrical outlet.

If charging light is not on, check position of radio. Radio should be upright. The charge indicator light will stay on as long as the radio is in the charging well, even after the batteries are fully charged.

It normally takes about 15 hours to fully recharge batteries. Batteries will not be damaged if they stay in the charging well longer than that.

Note: To charge a single radio, you can bypass the desktop charger and simply insert the wall adapter’s round connector directly into the

speaker/microphone/charge jack located on the top of the radio.

Use only the supplied rechargeable batteries and charger for recharging your Cobra microTALK radio.

Cobra recommends your radio is turned off while being charged. Non-rechargeable alkaline batteries can also be used in your radio.
