2.1.1 The Keys
All FFDs are provided with the following eight keys:
Power/Lights Key
Page Key
Scroll Up Key
Scroll Down Key
Enter/Reset Key
Speed/Depth Key
Wind Key
Navigation Key
2.1.2 Power/Lights Key
This key controls the application of power to the system and the
level of illumination at all displays.
One short press of this key applies power to the Hydra System
and the display is activated. A second short press of the key
provides full background illumination on all system displays.
Further short presses of the key decrease the illumination in three
stages from full brightness to OFF.
The next press gives full illumination again. This operation on any
one FFD within the system, performs the same sequence on all
Hydra displays connected to the system. However, display lighting
can be localised so that the level can be adjusted for individual
displays (see
Para 2.9 - LIGHTING CONTROL) .
To switch OFF the system, press and hold down the key for three
seconds. After this time lapses the message POWER-OFF
appears in the upper text, release the key and after a further two
seconds the system switches OFF and is now in Standby Mode.
2.1.3 Page Key
This key enables the user to select the User Defined Page
(Display) presented on the FFD.
By pressing this key the user is able to choose any one of four
user defined pages accessing various functions of the Hydra
2000 System (2 functions per page).
