Maintenance And Troubleshooting - BenQ PL19_D User Manual

Turning On/Off the Presence Detection Function
• Do not block the presence sensor on the lamp. Otherwise the presence
detection function will not work properly.
• With the presence detection function turned on, the lamp will
automatically calibrate the presence sensor when power is connected
to the lamp or when the lamp is turned off (whether manually or
automatically). The calibration process takes about 40 seconds. During
calibration, the Presence Detection button will blink and the presence
detection function will be disabled temporarily. When calibration is
complete, the Presence Detection button will turn steady and the
presence detection function will resume automatically.
• With the presence detection function turned on, if you manually turn off the lamp, the
presence detection function will be disabled temporarily for about 40 seconds to avoid the
lamp from being turned on accidentally.

Maintenance and Troubleshooting

• Turn off the lamp first, and unplug the lamp from the power outlet. Wipe any smears or dusts
off the lamp's outer casing using a soft, lint-free cloth lightly moistened with a mild detergent
solvent. Do not use alcohol or any other chemical solvents like kerosene, naphtha and so on, as
the lamp's casing may become damaged.
• Do not rinse the lamp or any of its components directly with water.
• If the lamp does not turn on, check to make sure that there are no loose connections between
the power cord, power adapter, and the power outlet.
• If the problem persists, please contact the original place of purchase for help.
The presence detection function allows for the lamp to turn on
automatically when you sit down by the piano, and off 10 minutes
after you leave.
To turn on the presence detection function, touch the Presence
Detection button on the lamp. The Presence Detection
button will first blink for 40 seconds and then turn steady, indicating
that the presence detection function is turned on and the detection
is in progress.
To turn the function off, touch the Presence Detection
again.
