RS86/RS87 VHF

E04819 Issue 1.0

6.2 Security mode (voice scrambler)

For additional security, a voice scrambler function is available

as an optional accessory. The scrambler uses frequency inver-

sion to encrypt the transmission and will allow secure transmis-

sion between compatible radios.

To enable Security mode press S

HIFT followed by 0 (SCRM). The

display will show “SEC” indicating that Security mode is on.

To exit Security mode, press S

HIFT followed by 0 (SCRM) again,

or press O

N/C. Security mode will be canceled, if the RS86/87

is placed into another mode that requires the use of the PTT

key (e.g. Hailer/Intercom), or if a DSC call is made/received.

6.3 Losing nav data

6.3.1 Losing SimNet data

If the selected SimNet nav data source is lost for any reason,

after 1 minute an alarm will sound to all station speakers and the

display will show “SOURCE DATA LOST” (Fig 6.2).

The alarm will also be sent across the SimNet bus, where it may

be repeated by other equipment that is able to do so.

Press O

K or ON/C to cancel the alarm and return to the previous

display. The alarm can also be canceled by other equipment on

the bus that is repeating the alarm.

Note If nav data is also being received via the NMEA 0183 input, the

RS86/RS87 will automatically switch to this source after the

loss of SimNet data.

6.3.2 Losing NMEA data

If the NMEA 0183 nav data source is lost (and no SimNet nav

data is being received), an alarm will sound to all station speak-

ers after one minute and the display will show “NMEA LOST”

(see Fig 6.3, p. 57).
