Silencing external alarms
Most external alarms can be silenced only at the alarm-initiating device e.g.
autopilot, GPS or master instrument. Exceptions to this are the
LOST FIX
ALARM
and the
LOW BATTERY ALARM
, which can be silenced by pressing any
of the ST60 Graphic Display front panel buttons.
1.7 How do I adjust the display backlighting?
When the instrument is first powered up, the display backlighting is set to its
lowest (courtesy) level, to facilitate initial access to the buttons. To adjust the
level of backlighting:
1. Hold down the
button for approximately 1 second, to enter the back-
lighting-adjust mode.
2. There are four preset backlighting levels. Momentarily press the
but-
ton to cycle through these levels until you reach the level you want.
3. Press any other button to leave the backlighting-adjust mode.
Note:
The display will time out to normal operation 5 seconds after the last
button press.
