conditions: 1) This device may not cause harmful interference, and 2) this device must accept any 
interference received,including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital 
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable 
protection against harmful interference in a residential installation. This equipment generates, uses 
and can radiate radio frequency energy and, if not installed and used in accordance with the 
instructions, may cause harmful interference to radio communications.

connected.
• Consult the dealer or an experienced radio/TV technician for help. 
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, modications 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.
FCC Part 15.21 Warning Statement-
NOTE: THE GRANTEE IS NOT RESPONSIBLE FOR ANY CHANGES OR MODIFICATIONS NOT 
EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE. SUCH MODIFICATIONS 
COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT.
IC RSS-GEN
This device complies with ISEDC license-exempt RSS standard(s). Operation is subject to the 
following two conditions: (1) this device may not cause interference, and (2) this device must accept 
any interference, including interference that may cause undesired operation of the device. 
Under ISEDC regulations, this radio transmitter may only operate using an antenna of a type and 
maximum (or lesser) gain approved for the transmitter by ISEDC. To reduce potential radio 
interference to other users, the antenna type and its gain should be so chosen that the equivalent 
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
The applicant is responsible for providing proper instructions to the user of the radio device, and any 
usage restrictions, including limits of exposure durations. The user manual shall provide installation 
and operation instructions, as well as any special usage conditions, to ensure compliance with SAR 
and/or RF eld strength limits. For instance, compliance distance shall be clearly stated in the user 
manual.
Radiation Exposure Statement:
Any Changes or modications not expressly approved by the party responsible for compliance could 
void the user’s authority to operate the equipment.
For Remote controller, SAR tests are conducted using standard operating positions accepted by the 
FCC/ISEDC with the device transmitting at its highest certied power level in all tested frequency 
bands, although the SAR is determined at the highest certied power level, the actual SAR level of 
the device while operating can be well below the maximum value.
Before a new model device is available for sale to the public, it must be tested and certied to the 
FCC that it does not exceed the exposure limit established by the FCC/ISEDC, Tests for each device 
are performed in positions and locations (e.g. at the ear and worn on the body) as required by the 
FCC/ISEDC.
For body worn operation, this model device has been tested and meets the FCC/ISEDC RF exposure 
guidelines when used with an accessory designated for this product or when used with an accessory 
that Contains no metal and that positions the handset a minimum of 10 mm from the body.
Non-compliance with the above restrictions may result in violation of RF exposure guidelines.
