The remote control transmits a directional infrared beam. Be
sure to aim the remote control directly at the infrared sensor
during operation. When the sensor is covered or there is a
large object between the remote control and the sensor, the
sensor cannot receive signals. The sensor may not be able to
receive signals properly when it is exposed to direct sunlight
or a strong artificial light (such as a fluorescent or strobe
light). In this case, change the direction of the light or
reposition the unit to avoid direct lighting.
Notes
• Handle the remote control with care.
• Do not spill water, tea or other liquids on the remote control.
• Do not drop the remote control.
• Do not leave or store the remote control in the following
conditions:
— high humidity or temperature such as near a heater, stove or
bath;
— dusty places; or
— extremely low temperature.
