2.4 BACKLIGHTING (BACKLIGHT) AND CONTRAST (CONTRAST)
Use BACKLIGHT to set the backlight levels for the LCD, the
keypad, and the microphone at the same intensity.
Use CONTRAST to set the contrast level for the LCD.
2.4.1 SET THE BACKLIGHTING LEVEL
1. Select BACKLIGHT.
2. Select the appropriate backlight level, or off (OFF).
Changes are effective when you exit from the screen.
Note that the DISTRESS key backlighting cannot be
switched off, even if OFF is selected.
2.4.2 SET THE CONTRAST LEVEL
1. Select CONTRAST.
2. Select the apropriate contrast level. Changes are
effective when you exit from the screen.
2.5 GPS DATA AND TIME (GPS/DATA)
If the boat has an operational GPS navigation receiver, the
VHF radio automatically detects and updates the vessel
position and the local time.
However, if the GPS navigation receiver is disconnected or
absent, you can specify the vessel position and the local
time manually, using the GPS/DATA option.
This information is important because it will be used if a DSC distress call is
transmitted.
2.5.1 MANUALLY ENTER POSITION & UTC TIME (MANUAL)
1. Select GPS/DATA, then MANUAL. Note that this function is available only if
an operational GPS receiver is not connected.
2. Enter the latitude, then the longitude, then the UTC.
