How does the RA685 work with your Full band license

The frequency band of RA685 is amateur band, but do you want it to work for your full band license? The answer is here.

by Cara

RA685 4 sides lookThe RA685 applied for certification for the European Enthusiast band, so it works in the European enthusiast band. Its frequency is:

144-146MHZ(RX/TX) 430-440MHZ(RX/TX)

However, some customers said that when the RA685 is enabled to work at full range by using the shortcut keys, it will be automatically adjusted to the hobbyist band the next time it is switched on. Therefore, in order to make RA685 better serve customers. We are upgrading this problem.

So, firstly, you should know if your firmware is the latest version.

Hold the side key 2 and turn on the radio, if you can check the firmware version, it means you can upgrade the new firmware. If not, please upgrade the firmware first.

When the progress bar reaches 100%, the upgrade is complete.

How to use shortcut keys to switch between the amateur band and full band?

Hold the PTT button and cumber 5 buttons to turn on your radio, the screen will display Amateur, then you are in an amateur band.

Hold the PTT button and V/M button to turn on your radio, the screen will display Factory, then you are in the full band now.
