Cleaning:
• Clean all units with a soft cloth and gentle cleaner. Do not spray cleaner directly on unit. Do not use an abrasive cleaner or cloth.
Wiring:
• When a short is detected between the door station and the expansion monitor station, the expansion monitor station stops functioning
and the Status LED flashes rapidly until the short is removed. The master monitor station does not indicate the short and stops its
operation with the door station. Check the wires.
• When a short is detected between the expansion monitor station and the master monitor station, the master monitor station stops functioning
and the Status LED flashes rapidly until the short is removed. The expansion monitor station operates with the door station normally.
• If noise is heard from the expansion monitor station, the wiring is disconnected between the video door station and the expansion monitor
station.
• If noise is heard from the master monitor station, the wiring is disconnected between the video door station and expansion monitor station or
between the master monitor station and the expansion monitor station.
Trouble:
• If the station does not respond, reboot this station by pressing the RESET button.
• When the power supply is turned off, power failure, or the RESET button is pressed, the setting of brightness, communication volume,
and call tone volume are returned to the default setting.
