3.7.9 Data Input
Data communications equipment requiring direct access to the modulator and discriminator
can be connected via pins 2 and 11. Data cannot be transmitted in CANADA unless
equipment is approved for use with the TFM-550 by the communications regulatory
authority.
3.8 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 600 memory
positions. 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-install the left side cover.
