Batteries for remote control
operation and backlight (four
size AA (R6) batteries)
Under normal conditions, batteries will
last up to 5 months. If the Commander
does not operate properly, batteries
might be worn out and E is displayed
on the LCD touch panel. When the
display dims or the backlight for the
touch keys grows dim, replace the
batteries with new ones.
Note
Do not take more than one day to replace the
batteries; otherwise, your setting of the code
numbers (page 8) and learned remote control
signals (page 16) will be erased.
Notes on batteries
• Do not mix old batteries with new ones or
mix different types of batteries together.
• If the electrolyte inside the battery should
leak, wipe the contaminated area of the
battery compartment with a cloth and replace
the old batteries with new ones. To prevent
the electrolyte from leaking, remove the
batteries when you plan not to use the
Commander for a long period of time.
