Preparations
Prepare the Remote Control
The provided Remote Control allows the unit to be operated from a distance.
•Even if the Remote Control is operated within the effective range (6m),
remote control operation may be impossible if there are any obstacles
between the unit and the remote control.
•If the Remote Control is operated near other products which generate
infrared rays, or if other remote control devices using infra-red rays are
used near the unit, it may operate incorrectly. Conversely, the other
products may operate incorrectly.
First-time use:
The unit has a pre-installed lithium CR2025 battery. Remove the protective
tab to activate the remote control battery.
Replace the Remote Control Battery
1. Pull out the battery tray and remove the old battery.
2. Place a new CR2025 battery into the battery tray with correct polarity (+/-)
as indicated.
3. Insert the battery tray back into the slot.

8
Precautions Concerning Batteries
•When the Remote Control is not to be used for a long time (more than a month), remove the
battery from the Remote Control to prevent it from leaking.
•If the batteries leak, wipe away the leakage inside the battery compartment and replace the
batteries with new ones.
• Do not use any batteries other than those specied.
•Do not heat or disassemble batteries.
• Never throw them in re or water.
•Do not carry or store batteries with other metallic objects. Doing so could cause batteries to short
circuit, leak or explode.
• Never recharge a battery unless it is conrmed to be a rechargeable type.
