2 OPERATION
2.1 General
The RD68 VHF is very simple to operate, with the controls
falling into five groups -
1. The rotary Volume/On/Off & Squelch controls.
2. The alphanumeric keypad used to select the channel, MMSI
number etc.
3. The dedicated controls, for commonly used functions such
as output power, dual watch and channel 16 select etc.
4. The four softkeys to the right of the display change their
function depending on what is displayed. The labels showing
the current function of each keys is shown on the respective
line on the right side of the display.
5. There is also a Distress alert button under a sliding cover.
This must only be used in an emergency - see section 5.1.
The radio functions are split into two main modes -
- Radio Mode allows access to the standard VHF radio
functions, such as tri watch, scan etc.
- DSC Mode covers the Digital Selective Calling functions.
These modes are toggled by pressing the top softkey (labelled
DSC or Rad).
At any stage of the DSC Mode menu structure, pressing the
DSC softkey will return to the DSC Mode main menu.
At any stage of the DSC Mode menu structure, pressing the C
key will cancel any unconfirmed action or step back one level
in the menu structure.
Some menu options will only be displayed if the relevant infor-
mation is available.
If the radio is receiving NMEA GPS data the current Lat/Long
will be displayed when in DSC Mode, and the time will be dis-
played in both Radio and DSC Modes in 24 hour UTC (GMT)
format (the local time can also be entered).
2.2 Rotary controls
The radio is switched on by turning the volume knob clock-
wise. To increase the volume, turn the knob further clockwise.
Turn the knob fully anticlockwise to switch off.
The squelch knob is used to adjust the receiver muting thresh-
old (squelch) level. To cut out weaker signals, increase the
squelch until the background interference noise disappears. To
receive weaker signals, decrease the squelch.
