CAUTION

Do not install the unit at following places.

1. It could cause break-down or deformation of unit.
   • Where it is exposed to direct sunlight
   • Where the ambient temperature becomes 0 °C or below, or 40 °C or above
   • Where the surface is not flat
   • Where the strength of installation area is insufficient
2. Moisture may be attached to internal parts of the unit, resulting in a display failure.
   • Place with high humidity where condensation occurs on the unit
   • Where the unit gets wet

Provide ground connection.
The ground line should never be connected to the gas supply piping, the water supply piping, the lightning conductor rod, or the telephone ground. If the grounding is incorrect, it may result in electric shock.

• Be sure to install a leakage breaker at the installation location.
  If a leakage breaker is not installed, electric shock may result.

• The device is not to be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given the correct supervision and/or instruction.

• Children must be supervised not to play with device.

• Clearances, creepage distances and solid insulation.
