Similarly, you can use the SPEED key to display the speed and log
pages in the Speed Chapter, and the NAV key to access any
navigational data that is received via SeaTalk or NMEA connections,
and displayed in the Nav Chapter pages.
The RayData Quick Reference Card, included with your RayData,
summarises the display pages available and the sequences in which
they are displayed. In addition, each page is described in detail in
Chapter 6.
3.6 Changing the Lighting
The level of lighting and contrast for the screen is controlled using the
DEPTH key, as indicated by the lamp symbol over the key on the
RayData front panel. The keys are always lit, so you will always be able
to read the key labels.
To change the screen lighting and contrast:
1. Press and hold the DEPTH key for one second. The lighting control
page appears. This is a temporary display, and reverts to the
previous page if you do not press a key for five seconds.
D3042-2
If the lighting was off before this page was displayed, the lighting is
automatically switched on at the highest level. If the lighting was
already on, the current lighting level is retained.
2. Press the DEPTH key to cycle through the lighting level options, HI,
LOW and OFF, until the required level is shown.
3. Press the
Ù Ù Ù Ù Ù
or
Ú Ú Ú Ú Ú
key to increase or decrease the contrast level
(in the range 1 to 16), until the required contrast level is shown.
After five seconds, or if you press SPEED, the display returns to the
page that was displayed before you selected the lighting control page,
with the new lighting and contrast levels. The contrast level is retained
until you reset it; the lighting level is retained until you reset it or turn the
RayData off.
