Hardware Hacking

Remove the back cover.

Find the small PCB that has the PTT and UP/DOWN switches on it.

On the reverse of this PCB you will find a group of three solder islands that end on the outside edge of the board.

Solder a bridge across all three islands.

Re-assemble the radio.

Now you will need to reset the microprocessor, this is done by removing the battery, turning on the radio and then shorting out the terminals for around 24 Hrs.

Once the microprocessor has been reset you can continue.

Make sure that the power switch is on, hold down the CH9 button and slide in the battery, you should now be able to hear the receiver, release the CH9 button and the display should appear.

Use the CH9 button to select 10 bands of 40 channels.

Now every time that you turn on the radio with the CH9 button pressed you will have 400 channels.

If you dont hold down the CH9 button when you power the radio you will have the standard channels.
