2. Insert the batteries, paying attention to match up the (+) and (-) ends of the batteries with the symbols inside
the battery compartment.
3. Slide the battery cover back into place.
REMOTE NOTES & TIPS
For optimum product performance:
• Do not mix old and new batteries, or batteries of dierent types.
• Do not leave batteries in the remote control if you don't plan on
using the device for more than 2 months.
• Do not dispose of batteries as unsorted municipal waste. Refer to
local laws for proper disposal requirements of batteries.
• Direct sunlight can interfere with the infrared signal receiver.
• There must be a clear line of sight between the remote and the
appliance.
• If the signals from the remote control happen to control another
appliance, move the appliance to another location or contact
customer service.
• Batteries may have a chemical symbol at the bottom of the disposal
icon. This chemical symbol means that the battery contains a heavy
metal that exceeds a certain concentration. An example is Pb: Lead
(>0.004%).
• Appliances and used batteries must be treated in a specialized facility
for reuse, recycling, and recovery. By ensuring correct disposal, you
will help avoid possible negative consequences for human health &
the environment.
3.2 Remote Interference
