        WARNING: Important Safety Instructions for Battery

Read All Instructions 

• Do not incinerate the battery even if it is severely damaged or is completely worn 

out.

• Do not discard battery in a fire. The battery pack can explode in a fire. 
• Do not replace battery in any area labeled “Hazardous Atmosphere”. Any sparks 

created in a potentially explosive atmosphere can cause an explosion or fire.

• Do not disassemble, crush, puncture, shred, or otherwise attempt to change the 

form of your battery.

• Do not dry a wet or damp battery with an appliance or heat source, such as a hair 

dryer or microwave oven.

• A small leakage of liquid from the battery cells may occur under extreme usage or 

temperature conditions. This does not indicate a failure.  Do not open, deform or 
mutilate the battery as there may be corrosive materials which can cause damage 
to eyes or skin and may be toxic if swallowed.

However, if the outer seal is broken and this leakage gets on your skin: 
a. Wash quickly with soap and water. 
b. Neutralize with a mild acid such as lemon juice or vinegar. 
c. If battery liquid gets into your eyes, flush them with clean water for a minimum of 

10 minutes and seek immediate medical attention.

This product uses Lithium Polymer Battery. Do not transport package if damaged, a 
fire hazard could exist.

Recycle Battery 

Disposing of this battery correctly will help save valuable resources and prevent any 
potential negative effects on human health and the environment, which could 
otherwise arise from inappropriate waste handling. Please contact your dealer or 
supplier for recycling advice.

1.  Only accessories included in this package or specified by the manufacturer 

should be used with the radio. The 5V micro-USB charging input is compatible 

with most high quality micro-USB chargers that fully conform to the USB 

standards.

2.  Do not use cleaners or solvents to clean the exterior of the radio. Use only a 

damp or dry cloth.

3.  Do not expose this product to splashing or dripping water.
4.  Do not attempt to service the receiver yourself. Removing the cover will void 

the warranty. Changes or modifications not expressly approved by Cobra may 

void the user’s authority granted by the FCC to operate this device and should 

not be made.

5.  Do not plug the wall adaptor into the power outlet if the outlet is wet.
6.  Do not use any portable radio that has a damaged antenna. If a damaged 

antenna comes into contact with your skin, a minor burn can result.

WARNING: Important Safety Instructions

Before operating the radio, please read all safety and 

operating instructions. Save all instructions in a safe place 

for future reference.

Introduction

Customer Assistance

Operational Cautions

Exposure to high volume sound levels may cause temporary or permanent 

damage to your hearing. Although there is no single volume setting that is 

appropriate for everyone, you should always use your radio with the volume set 

at low level and avoid prolonged exposure to high volume sound levels.
1. Set the volume control in a low position and use as low a volume as 

possible.

2. Avoid turning up the volume to block out noisy surroundings. Whenever 

possble, use your radio in a quiet environment with low background noise.

3. Limit the amount of time you use headsets or earpiece at high volume 

levels.

4. When using the radio without a headset or earpiece, do not place the radio’s 

speaker directly against your ear.

5. Observe all signs and instructions that require an electrical device or RF 

radio product to be switched off in designated areas, such as gas/refueling 

stations, hospitals, blasting areas, potentially explosive atmospheres, or 

aircraft.

6. If you experience a skin irritation after using this product, discontinue use 

and seek medical attention.

7. If the product or charger: overheats; has a damaged cord or plug; has been 

dropped or damaged; has been dropped into water, disconnect any charger 

from its power supply, discontinue use of the product.

Electromagnetic Interference

Nearly every electronic device is susceptible to electromagnetic interference 

(EMI) if inadequately shielded, designed, or otherwise configured for 

electromagnetic compatibility. Turn off your radio in any facility where posted 

notices instruct you to do so. These facilities may include hospitals or health 

care facilities that may be using equipment that is sensitive to external RF 

energy.
• When instructed to do so, turn off your radios when on board an aircraft. Any 

use of a RF device must be in accordance with applicable laws, regulations 

and airline crew instructions.

• Some radios may interfere with some hearing aids. In the event of such 

interference, you may want to consult your hearing aid manufacturer or 

physician to discuss alternatives.

• If you use any other personal medical device, consult the manufacturer of 

your deivce to determine if it is adequately shielded from RF energy. Your 

doctor or physician may be able to assist you in obtaining this information.

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.
For ease of use and to reduce interference from other users, the 16 channels 
of your radio have been customized, see 

Channel and Default Privacy 

Code Table

.

You can change your radio Privacy Codes in order to work with other 
radios with different privacy codes or radio without privacy codes. See
