Top left is vertikal row with resistors be seen.
Beside the resistors to the right a vertical row with diodes is located.
From top is the diodes called D1, D2, D3, HD4, D5, D6, D7, HD8.
- To enable RX 136-174MHz Remove D5.
- To enable RX 420-480MHz Remove D6.
- To enable RX 1240-1320MHz Remove D7.
- To enable narrow FM on 1,2GHz band install a 1SS355 diode at HD8.
- TO enable crossbandrepeater install HD4
To use crossbandrepeater:
- Activate [LOCK]
- Switch off the radio.
- Puch and hold M/S while switch on the radio.
To exit push [LOCK]
(Crossbandrepeat will not be canceled if power is switched off.)
