8-Point Digital Compass

Your microTALK

®

digital compass. 

Because the surrounding terrain 
can affect compass accuracy, it is
recommended that you calibrate 
the compass before each use. It is
important to keep the radio parallel 
to the ground at all times while
calibrating and using the compass.

To Calibrate the Compass:
1. Press and hold the Compass button for two

(2) seconds. The Compass icon and “CALIbr”
will appear in the display.

2. Hold the radio in front of you, parallel to the

ground, and turn around in a circle at least
two (2) times (or you may place the radio 
on the palm of one of your hands, parallel 
to the ground, and turn it in a circle at least 
two (2) times with your other hand).

3. Press the Compass button again. 
4.  a. If compass calibration was successful,

“SUCCES” will appear in the display for 
one (1) second, then the radio will
automatically return to Compass Mode.

b. If “FAIL” appears in the LCD, repeat steps 

1 through 3. (If you receive repeated “FAIL”
messages, change locations and repeat
steps 1 through 3.)

Range

Your microTALK

®

radio has a range of up 

to ten (10) miles (16 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 
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 22 for details.

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 Commissions
(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.
