Modifications Instruction

Not all versions will get full expansion

Most radios will operate within a 20-30 MHZ range of the original frequency.

1 - Remove battery and antenna.
2 - Remove screws and open the radio.
3 - Remove D23 ( This part is already removed on US version ).
4 - Attach diode as shown ( Use 1N914 or equivalent diode ).
Make sure Diode leads will not short anything. Cover then in tape.
5 - Reassemble the radio.
6 - Reset the radio.
7 - Turn radio on, Hold [ Light ] & [Function ], turn radio off and on.
