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.

Privacy Codes 

Your microTALK radio incorporates two advanced coded squelch 

systems that can help to reduce interference from other users  

on any given channel. CTCSS (Continuous Tone Coded Squelch 

System) provides 38 privacy codes and DCS (Digitally Coded Squelch) 

provides 83 privacy codes. This provides a total of 121 

Privacy 

Codes

. Either system can be used on all channels, but both systems 

cannot be used on the same channel at the same time.

To successfully communicate using a privacy code, both  

the sending and receiving radios must be tuned to the same 

channel and to the same privacy code system (CTCSS or DCS) 

and privacy code number. Each channel will remember the last 

privacy code system and number you select.

The privacy code 00 is not a privacy code, but allows all signals 

to be heard on a channel that is set to 00 on both  

the CTCSS and DCS systems.

Set CTCSS Privacy Codes 

To select a CTCSS privacy code:
1.

  After selecting a channel, press  

the 

Mode/Power

 button until the 

CTCSS

 icon 

appears and the small numbers next to the 

channel number flash on the display.

the display will flash the  

CTCSS icon and “OFF.” To switch from  

DCS to CTCSS, press the 

Channel Up

  

or 

Channel Down

 button while the display 

is flashing “OFF.” The display  

will then show the small numbers flashing 

and you will then be able  

to proceed to step 2.

2.

  Press using the 

Channel Up

 or 

Channel Down

 

button to select a privacy code. You can hold the 

Up

 or

IMPORTANT NOTICE: FCC LICENSE REQUIRED 

This two-way radio operates on GMRS (General Mobile Radio Service) frequencies 
which require an FCC (Federal Communications Commission) license. A user must be 
licensed prior to operating on Channels 1 through 7 on high power or 15 through 
22, which comprise the GMRS channels of this radio. Serious penalties could result for 
unlicensed use of GMRS channels, in violation of FCC rules. Operation of this radio is 
subject to additional rules specified in 47 C.F.R. Part 95. 
Licensed users will be issued a call sign by the FCC, which should be used for station 
identification when operating this radio. GMRS users should also cooperate by engaging 
in permissible transmissions only, avoiding channel interference with other GMRS users, 
and being prudent with the length of their transmission time. 
For licensing information and application forms, please call the FCC Hotline  
at 800-418-FORM. Request form #159 and form #605. Questions regarding  
the license application should be directed to the FCC at 888-CALL-FCC.  
Additional information is available on the FCC’s website at www.fcc.gov.
Channel 1 through 7 on low power and channels 8 through 14 comprise the  
FRS (Family Radio Service). No license is required to operate on the FRS.

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 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. 

Normal Position

Hold the transmitter approximately 2 inches from your face and speak in a normal 
voice, with the antenna pointed up and away.
