Microtalk Radios: Troubleshooting
My radios get short range
Please note that the advertised range is only under ideal conditions such as:
-Absolutely no obstructions between the radios (for example communication over water or from mountaintop to mountaintop)
To maximize range, please make sure that the batteries are fully charged. If your radios use AA size or AAA size batteries, then you can try regular alkaline batteries.
Channels 8 to 14 are locked on low power per FCC regulations, so try using channels 1 to 7 or channels 15 to 22.
On some models you can adjust the transmit power level. Make sure it is set to HI.
Please note that use inside a building or inside a car will reduce the range.
When I turn on my radio it shows low battery
When you turn on your radio it will perform a display test. Everything will light up on the display, including the low battery icon. The display test lasts a couple seconds, after which you will get the normal operating display.
Please ignore the low battery icon during power-up. After the display test is done you can then see if the low battery icon is showing. If the batteries are low then the low battery icon will be flashing.
The CALL function is not working between different models
Cobra has used two different types of call signal: analog and digital. A digital call signal is used on models with VibrAlert, and is necessary in order to activate the vibrate feature. Models without VibrAlert use an analog call signal.
Digital call signals are not fully compatible with analog call signals. If your Cobra radio has VibraAlert, then it has a digital call signal that will only work properly with other Cobra VibrAlert models.
I purchased new batteries and they will not charge
Numerous models of Cobra handheld radios have a special feature which prevents accidentally charging alkaline batteries. If alkaline batteries are charged, they will leak!
To prevent charging alkaline batteries, the radio has a separate charge contact which touches the side of the battery.
Alkaline batteries have a plastic wrapper all the way down, so they will not touch the charge contact and will therefore not charge.
The issue is that other brands of rechargeable batteries also have a full wrapper, and so they too will not charge. The solution is to peel the wrapper from the negative end of the battery. Use a sharp knife to score all the way around, and then peel off the wrapper so that the battery looks like the picture above. Do it to all the new batteries.
Why does my radio switch to medium power when a headset is plugged in?
This is due to FCC regulations.
The FCC has set exposure limits on how much RF energy is allowed to be absorbed by your body. The transmit power must not exceed the SAR limits. The amount of allowed power will depend on variables such as the transmit frequency, proximity of the antenna, etc.
Typically when a headset is plugged into the radio, the radio is then worn on the belt using the integral belt clip. This places the antenna right up against your body. The FCC mandates that we must therefore lower the transmit power in order to stay within allowable exposure limits.
If you need absolute maximum transmit power, you will need to unplug the headset.
International Use of FRS/GMRS Radios
Can I bring my GMRS radios into Canada or Mexico?
Yes. Your Cobra GMRS radios are legal for use in the USA, Canada, and Mexico. You can freely bring your GMRS radios into both Canada and Mexico. Enjoy your trip!
Can I bring my GMRS radios to Europe?
No. Most countries in Europe have adopted a different standard known as PMR ("Personal Mobile Radio"). While PMR radios are very similar to your GMRS radios, PMR radios use different frequencies. If you attempt to bring your GMRS radios into Europe, they might get confiscated in customs.
PMR radios are currently approved for use in the following countries: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Lithuania, The Netherlands, Poland, Portugal, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
Does Cobra sell PMR radios?
Cobra manufactures and sells PMR radios and is a leading brand in Europe. PMR radios are not available in the USA because they are not FCC-approved. They are only available in European countries where PMR has been approved for use. Please visit local retailers in those countries.
PMR has been approved in the following countries:
Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Lithuania, Netherlands, Poland, Portugal, Spain, Sweden, Switzerland, Turkey, United Kingdom
