Operating Requirements

• Do not allow children to play with the device or accessories. Swallowing the accessories may be fatal.
• Use only accessories, such as the power adapter and battery, provided or authorized by the manufacturer.
• Ensure that the device does not get wet. If water gets into the device, disconnect the power supply immediately and unplug all the cables connected to the device, such as power cables, telephone cables, and RF cables, and then contact the appointed maintenance center.
• Before plugging in or unplugging any cable, shut down the device and disconnect the power supply. While plugging in or unplugging any cable, ensure that your hands are dry.
• Do not step on, pull, or over bend any cable. Otherwise, the cable may be damaged, leading to malfunction of the device.
• Do not use old or damaged cables.
• During electrical storms, disconnect the device from the power supply and unplug all the cables connected to the device.
• Keep the power plug clean and dry, to prevent electric shock or other dangers.
• If the device is not used for a long time, disconnect the power supply and unplug the power plug.
• If smoke, abnormal sound or smell is emitted from the device, stop using the device immediately, disconnect the power supply, unplug the power and other cables, and remove the batteries. Then, contact the appointed maintenance center for repair.
• Ensure that no object (such as metal shavings) enters the device through the heat dissipation vent.
• Before connecting any other cable, connect the ground cable of the device. Do not disconnect the ground cable until you have disconnected all the other cables.
• Ensure that the three-phase power socket is properly grounded. The neutral line and the live line cannot be connected inversely.
• Do not scratch or abrade the shell of the device. The shed paint may cause allergic reaction or malfunction of the device. If the shed paint material drops into the host, a short circuit may occur.

Cleaning Requirements

• Before cleaning the device, stop using it, disconnect the power supply, and unplug all the cables connected to the device, such as the power cable, telephone cable, and RF cable.
• Do not clean the device shell with any cleaning solution or cleanser spray. Use a piece of soft cloth to clean the device shell.

Lithium Ion Battery Usage Requirements

• Do not store the battery at a temperature of 60°C or above.
• Do not charge the battery at a temperature of 0°C or below.
• Use the dedicated charger delivered with the battery. Otherwise, the device may be damaged.
• Keep the battery away from fire.
• Do not strike the battery or hit the battery with sharp objects.
• Do not connect a metallic object such as a key to the positive and negative terminals of the battery. Otherwise, a short circuit may occur, and you may be injured due to excessive heat of the battery.

LCD Usage Requirements

• Do not expose the LCD to direct sunlight.
• Do not press, scratch, or beat the LCD, or place heavy objects on top of it.
• Do not watch the LCD screen for a long time. This may harm your eyes or blur your vision.

Wireless Product Usage Requirements

• Keep the wireless device away from magnetic storage devices, such as a magnetic card or floppy disk to prevent loss of the stored information.
• Stop using the wireless device and disconnect it from the power supply in places where using wireless devices is prohibited or using wireless devices may lead to interference or danger.
• Unplug the wireless device from the terminal and turn off the terminal close to a high-precision controlled electronic device, such as an audiphone, a pacemaker, fire alarm, or an automatic gate. Otherwise, this may lead to malfunction of the electronic device.
• Users who use an electronic assistant medical-treatment device must confirm the effects of radio waves on their device with the service center.
• Do not take a wireless device into an operating theater, Intensive Care Unit (ICU), or Coronary Care Unit (CCU).

• If the battery fluid contacts your skin or clothes, rinse with water immediately and seek medical assistance.
• If the battery fluid goes into your eyes, do not rub your eyes. Rinse your eyes with water immediately and seek medical assistance.

ESD

Electrostatic charge builds up on your body when you move, rub against cloth, walk across the floor, or hold plastic items. The charge will then remain until it discharges by either gradually leaking away to ground or in a fast discharge spark. Before touching any of the devices or tools, ensure that you are wearing an ESD wrist strap and that the strap's other end is properly grounded to prevent electrostatic discharge from damaging sensitive components.

Sharp Edges

Wear safety gloves when moving and lifting the system to mitigate the risk of cutting your hands on the system's sharp edges.

Signal Cable Bundling

Signal cables must be bundled separately from heavy-current or high-voltage cables. The minimum distance between bundles is 150 mm.
