Where would I use these PMRs?
Whether you’re at a festival or hiking in the country, keep in touch with these Cobra MT645 two-way radios. These PMR 446 radios use the 446 MHz frequency band for communication between the two units. With up to 8km range in open conditions, these radios are powerful units with no need for a licence or call plan. Backlit LED screens let you see what you’re doing in the dark. They even come with a clip to secure the radios to your belt. For more covert conversations or just to cut down the ambient noise, the MT645 units can be attached to a compatible headset.

Will these radios be effective in closed conditions?
These two-way radios reach their maximum 8km range in open conditions. Even with obstacles between the units, they will provide effective communication. Cobra estimates that in ideal conditions, the MT645 will transmit up to approximately km in a hilly location and up to approximately km in a built-up city. A great radio for festivals, shops or walking with.

How many frequencies do these two-way radios have?

Never struggle for a clear frequency – each unit has 8 channels which have 121 privacy codes for a total of 968 privacy combinations. Comes with voice activated transmission (VOX) for hands free transmissions. Roger beeps can used to give a bleep after you’ve finished talking to let others know its fine to talk and can be switched or off. Using key lock, you won’t need to worry about accidentally changing your channel and missing a message.

How do I charge my radios?
The radios have a microUSB charging socket and come with a lead to charge all the radios from one USB socket (socket not included). At a festival with no access to mains power? No worries, just replace the batteries with alkaline AA batteries(not included) and keep going. You can even charge the handsets from a USB car accessory socket adapter (not included Order Code N77EA)as well as mains USB socket adapters (not included Order Code A70WC). The handset includes a battery level indicator so you should always know how much battery you have left. The MT645 has a power saving mode so it can run for up to 8 hours on a full charge and up to 24 hours on standby.

These two-way radios are compatible with most PMR 446 units with the same channel and privacy combinations.
