What are the precautions for using the WJ-SX650 Panasonic matrix switch?

WJ-SX650 Panasonic Matrix Switch Use Note:

For use by qualified service personnel only. Do not perform any maintenance work other than the instructions in the manual unless you are qualified to avoid the risk of electric shock • Do not block the ventilation openings or slots in the cover. To prevent the device from overheating, place it at least 5cm away from the wall.

• Do not drop metal objects into the groove. This may cause the device to suffer permanent damage. Disconnect the power supply and have it serviced by qualified service personnel.

• Do not attempt to disassemble the device. To avoid electric shock, do not remove the screws or there are no user-serviceable parts inside the lid. If necessary, ask qualified maintenance personnel to perform repairs.

• Do not bump the device or subject it to strong vibrations. Do not allow water to enter the camera to prevent damage to the equipment.

• Do not expose the device to water or moisture. Do not operate the device in wet areas. When the device is wet, take immediate action. Turn off the power immediately and have qualified service personnel perform repairs. Moisture can damage the equipment and also cause electric shock.

• Built-in backup battery. Before using for the first time, turn on the power for 48 hours or more to charge the backup battery. If the back-up battery is not fully charged, the internal clock may malfunction in the event of a power outage and the operating conditions may differ from those before the power failure. The built-in battery life needs to be replaced about 5 years. (This simply means that it needs to be replaced. We do not guarantee the built-in battery life. Even if the battery needs to be replaced during the warranty period, the cost of replacing the battery is not guaranteed.) When you need to replace the battery, ask the supplier who purchased the equipment.

• Turn off the power while cooling the fan cleaning device. It may cause injury. The cooling fan can work for about 30,000 hours. Even if the cooling fan needs to be replaced during the warranty period, the cost of replacing the cooling fan is not guaranteed.

• Turn off the power while cleaning the cleaning device. It may cause injury. Do not use strong or abrasive cleaners when cleaning the unit body. When the device is dirty, wipe it with a dry soft cloth. If dirt is difficult to remove, wipe it off with a mild detergent.

• Do not use the device outside of temperature, humidity, or power supply specifications. Use the unit at a temperature of -10°C to +50°C and humidity less than 90%. The unit may not work properly after being turned on in a cold environment from -10°C to 0°C. Wait about 10 minutes until the internal temperature rises to 0°C. The input power supply voltage of this device is 220V to 240V, 50Hz AC.

• Place the device horizontally on a flat surface. Do not place the device in a vertical position. When more than one device is stacked, leave 5cm or more space on both sides of the device, top, bottom, and back.

• Pay attention to static electricity. The circuit board must be stored in an anti-static bag before installation. Place static electricity on the metal surface instead of the circuit board before installation. Do not touch the components mounted on the circuit board directly with your hands. Only hold the sides of the board when installing.

• Do not use other power cords other than the AC adapter supplied with this unit. Use the power cord that is appropriate for your location.
