Read these instructions carefully and save them for future reference.

  • All cautions and warnings on the equipment should be noted.
  • Lay this equipment on a stable surface during set up. A drop or fall could cause damage.
  • The warranty will be invalidated if the device is damaged during installation or replacement of system expansions.
  • Use the original power adapter and power cord only.
  • Make sure the power adapter and power cord are laid so that people do not step on them. Do not place anything over the power adapter or power cord.
  • Disconnect this equipment from the main supply before cleaning. Do not use liquid or spray detergent to clean. Clean only with a wipe or cloth.
  • Before opening the device, first, switch it off and then disconnect the power plug. Observe the specification in the user manual.
  • If the equipment is not used for a long time, disconnect the equipment from the main electric supply to avoid damage by transient overvoltage.
  • Make sure that no liquids leak into the device (danger of electric shock, fire, short circuit).
  • Do not insert foreign objects into the device (danger of electric shock, fire, short circuit).
  • If one of the following situations occurs, have the equipment checked by service personnel:
    • The power adapter, power cord or plug is damaged.
    • The equipment has been exposed to moisture.
    • The equipment does not work well, or you cannot get it working according to the user manual.
    • The equipment has been dropped or damaged.
    • The equipment has obvious signs of breakage.
  • Do not leave this equipment in an unconditioned environment. Storage temperature below -20 °C (-4 °F) or above 60 °C (140 °F) may cause damage to the equipment.
  • Do not use this equipment in an unconditioned environment. Unless otherwise stated in the technical specifications, operational conditions may not exceed the following limits, it may damage the equipment:
    • Vertical usage:
      Temperature: 0 °C to 35 °C, 32 °F to 95 °F
      Humidity: 20 % to 80 %, non-condensing
    • Horizontal usage (only with optional rubber feet, no VESA mount):
      Temperature: 0 °C to 35 °C, 32 °F to 95 °F
      Humidity: 20 % to 80 %, non-condensing
  • To avoid overheating in the horizontal position, use the optional rubber feet and tilt the device to the left so that the power button is on the left-hand side.
  • Note that even in closed rooms local temperatures may increase, for instance in case the device is exposed to strong sun radiation. Protect the device from external heat sources.
  • Ensure that air is free to circulate through the product. Do not use in a poorly ventilated place. Do not cover it with a cloth or place it on soft ground. Objects surrounding the device may block the airflow. Keep a minimum distance of 20 cm around the device for sufficient ventilation.

Lithium Battery Caution

  • The lithium battery (button cell) installed in the device may only be replaced by authorized, specially trained personnel.
  • Contact your supplier or the manufacturer for servicing and repairs.
  • Danger of explosion if the battery is incorrectly replaced. The lithium battery may only be replaced with a battery identical or equivalent to the one recommended by the manufacturer.
  • Dispose of used batteries according to the manufacturer’s instructions.

Excessive Sound Pressure

Excessive sound pressure from ear-/headphones can cause hearing damage/hearing loss. Adjustment of the volume control as well as the equalizer to other settings than the center position may increase the ear-/headphones output voltage and therefore the sound pressure level. The use of factors influencing the ear-/headphones output other than those specified by the manufacturer (e.g. operating system, equalizer software, firmware, driver) may increase the ear-/headphones output voltage and therefore the sound pressure level.

UL 62368

This equipment must be grounded. The power cord for the equipment must only be connected to socket-outlets providing earthing connection.
