STNBY Deactivation
This setting defines, which event can return the RT-800 device from the standby mode to the
normal operation.
▪
If “Automatic” is set, the device will get back to the normal operation by the occurrence
of an event, e.g. reception of a valid signal (s. 6.5.1).
▪
If “User” is set, the standby mode can only be deactivated manually by pressing any
key (except the On/Off (“Power”) button).
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-800”) can be sent out over the NMEA interface to
confirm the alarm.
