STANDBY status
The display remains ON during STANDBY only if the -20V is present. If the -20V is absent, the
display turns OFF. When the display wakes up from STANDBY and –20V is applied, the display
turns ON with previous value.
Switching off the display before entering the STANDBY state is recommended.
When the same display configuration command is sent, the display remains ON. When the
display configuration command is changed, the display is OFF.
Only hot key detection can wake the system up from STANDBY condition.
