User Manual
Note
To completely turn off the DCU’s illumination in the “Dark Mode”, the settings “Display
Brightness” and “Key Illumination” must be set to “Off”. This means that the DCU remains dark
even if a signal is received.
The communication with the DCU in this mode can be maintained over NMEA or LAN
interfaces (using NMEA data protocol), if desired.
Note
If the “Dark Mode” is activated while either the main bearing frequency is an emergency
frequency or a scan with any emergency frequency is active, the occurrence of the
corresponding signal will be indicated by the acoustic alarm even in the “Dark Mode”.
To switch off the alarm in this case, the device must first be returned to the normal operation,
or a corresponding NMEA sentence (“ALARMCFM”, for more information s. “NMEA-Protocol
Description (RT-500-M & RT-800)”) can be sent out over the NMEA interface to confirm the
alarm.
Note
Do not use the “Power” button in order to return the DCU from the “Standby Mode” into normal
operation!
Pressing the “Power” button for about 2 seconds leads to switching off the DCU and after
restarting the device, it works in the normal operation mode (with normal display brightness).
To change the “STNBY Deactivation” value, press the “Edit Value” hotkey, while “STNBY
Deactivation” is marked.
Following dialog opens (s. Figure 100. Changing the standby deactivation setting Figure 100).

o
Press the hotkey “Automatic” (s. Figure 100, position 1) in order to enable the automatic
standby mode deactivation.
o
Press the “User” hotkey in order to deactivate the standby mode manually.
o
Use the “Set Default” hotkey to change to the default setting (“Automatic”).
If the “STNBY Deactivation” setting is changed to “User”, leaving the “Standby Mode Settings” dialog
by pressing “OK” will generate a warning (s. Figure 101) in order to indicate the only manual
deactivation of the standby mode from then on.
