INTERNAL PROGRAMMING AND GUARD ENABLE/DISABLE JUMPER
The programming and direct frequency entry modes can be disabled by removing the internal
enable/disable jumper strap from pins 1 and 2 of J10. Removal of this jumper will prevent
operation on any frequencies other than those programmed in the 400 memory positions and
two guard receiver memory positions. Removal of the guard receiver programming enable /disable
jumper strap from pins 1 and 2 of J11 will totally disable the operator’s ability to re-program the 2
guard receiver channels.
The transceiver is always shipped with the two jumpers in the entry enable positions. To place
either of the jumpers in the disable position:
1. Remove the left side of the radio.
2. Set or remove jumpers as necessary.
3. Re-assemble the radio in the reverse order.
