7.5 Other Operational Functions
7.5.1 Standby Mode
The RT-500-M DCU provides a “Standby” mode.
By pressing the button (s. Figure 8, position 2), the standby mode is activated, and the
button is highlighted in orange. The colored illumination intensity of this button (as well as the “Power”
and “Mute” buttons (labeled “Keys”, s. 7.5.4)) can be adjusted in the “Adjust Brightness” dialog (s.
7.5.4).
While in standby, the brightness of the display is driven down to a defined value (configurable in the
“Setup” page, s. 7.4.2.8), but the system continues monitoring the corresponding (emergency)
frequency, and the keypad stays active.
After the activation of the standby mode the brightness of the legends and “Keys” stays at the
previously adjusted value (to turn off the illumination of the legends refer to 7.5.4, to completely turn
off the illumination of the “Keys” refer to 7.4.2.8, “STNBY Deactivation”).
Return from Standby:
o
Pressing any button as well as the “STNBY” button itself returns the system from standby
mode to normal operating mode (the function of the button pressed is not performed at the first
press).
o
The display is turned on again (by default) when an event occurs, e.g. signal level rises above
squelch level, alarm occurs, scan algorithm finds an active frequency or any button (except the
“Power” button) is pressed. This behavior can be changed to “Dark Mode” in “Standby Mode
Settings” (s. 7.4.2.8).
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, the device must first be returned from the standby mode.
Note
Returning the device from standby mode by pressing the “Power” button does not work!
Especially in the “Dark Mode” the attention must be paid that if this button is pressed
continuously for over 2 seconds, the device will be powered off. After turning on again, the
device will work in the normal operation mode (not standby mode).
7.5.2 Adjusting the Volume
The volume adjustment button (s. Figure 8, position 3) contains two keys: “+” and “-”
(twin function key).
Pressing any of the two keys opens the dialog for adjustment of internal and external speaker.
