9.2 Optical switches

The optical switches can be operated through the glass. The following keys are usable.
The optical keys are designed to enable stable operation and never respond to the taint on the surface of glass,
however, if a wrong reaction of optical switches is generated, the life duration of battery may shorten. (※) Keep
the surface of glass clean all the time so as not to cause wrong reaction of optical switches. Do not put an object
within 10cm from front surface of product (glossy object causes wrong reaction of optical switches).
