microTALK® Range

Your range will vary depending on terrain and conditions.

Maximum Range

Reduced Range

Signal Strength Meter

Your microTALK® radio has a Signal Strength Meter that shows the strength of your incoming

and outgoing transmissions. The ascending bars next to the signal strength indicate the strength of the signal. The greater the number of bars visible, the stronger the signal. The fewer number of bars visible, the weaker the signal.

In flat, open country your radio will operate at maximum range.

Buildings and foliage in the path of the signal can reduce the range of the radio.

Dense foliage and hilly terrain will further reduce the range of the radio.

On FRS channels 8 through 14, your radio automatically switches to low power, which will limit the range the radio can communicate.

Remember, you can achieve maximum

range by using maximum range extender. See page 6 for details.
