3.1 On/off switching
The procedures below consider that DC power is supplied to the display. Please check the status of
the power mode LED to verify that your display is supplied with DC power (see “Power status LED ”,
page 19).
When the DC power is supplied to the display, all LEDs of the front keyboard will turn on for 1
second. After this, the front keyboard calibration is performed (all white LEDs will turn off and the
central LED will turn orange).
Do not touch the front keyboard during calibration (less than 4 seconds). When the calibration is
complete, the front keyboard is available and can be used (the central LED will turn steady green or
blinking green / orange).
To switch on your display
With the front keyboard:
1. Press and hold (3-4 seconds) the key until the entire front keyboard starts blinking.
2. While the front keyboard is blinking, release the key again (within 2 seconds, to avoid a keyboard re-
lock) and the display will switch on.
With the rear keyboard:
1. Press and hold (3-4 seconds) the center button until the entire front keyboard starts blinking..
2. While the front keyboard is blinking, release the center button again (within 2 seconds, to avoid a
