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.
