If the remote control fails to operate display functions, replace the batteries in the remote control.

Open the battery
compartment cover.

Load the supplied AA
batteries.

Close the battery
compartment cover.

• Slide the cover in the direction

of the arrow.

• Place the batteries with their

terminals corresponding to the
(+) and (–) indications in the
battery compartment.

• Slide the cover in the direction

of the arrow.

Battery handling precautions
Improper use of the dry batteries can result in a leakage of the battery fluid and/or rupture. Be sure to
especially keep in mind the points below.
• Place the batteries with their terminals according to the (+) and (–) locations.
• Different types of batteries have different characteristics. Do not mix batteries of different types.
• Do not use old and new batteries together. Mixing old and new batteries can shorten the life of new

batteries and/or cause old batteries to leak battery fluid.

• Remove batteries as soon as they are exhausted. Fluid leaking from the batteries can cause a rash. If

fluid has leaked out, wipe it off with a cloth.

Remote control handling precautions
• Do not expose the remote control to harsh knocks. Do not place the remote control where it can get

wet or where the humidity is high.

• Do not place the remote control on a location where it is exposed to direct sunlight.

The heat can deform its plastic exterior.

• When the remote sensor window of the display is exposed to direct sunlight or to a strong light

source, remote control may prove to be difficult. Change the direction of the light source or of the
display or operate the remote control from a location closer to the remote sensor window.

• The batteries that came with the unit may not operate as long as new batteries due top storing conditions. Replace

them with new batteries at an early stage.

• If the remote control is not used for extended periods of time, remove the batteries.

The following diagram shows an example of system connection, on which this Operation
Manual is based.
