SPECIAL REQUIREMENTS FOR CRITICAL COMPONENTS

The device is equipped with a liquid crystal display (LCD), which contains small amounts of toxic
materials.
Observe the following instructions carefully in order to avoid personal injury and to prevent
environmental pollution:

LCD Display:

• The electronic control unit's LCD display is fragile (glass) and must be handled with care. For this
reason, it is recommended to protect the device with its original packaging during transport or
whenever it is not in use.
• In the event that the glass of the LCD display should break and liquid should come out, be careful
not to touch it. Carefully wash every part of your body that may have come into contact with the
liquid for at least 15 minutes. If any abnormal symptoms should arise after this operation has been
performed, seek immediate medical attention.
