microTALK®Range

Your microTALK®radio has a range of up to 12 miles (19 km).
Your range will vary depending on terrain and conditions.

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

Buildings and foliage in the path of the

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 5 for details.
