  Receiving beep is not emitted when a signal is transmitted.

•

  Display fades away.

NOTE

•

  Do not use old and new batteries together.

•

  Remove the batteries when the remote control is not used for a long period.

•

  The recommended effective period of a battery conforming to JIS or IEC 

should be 6 to 12 months with normal use. If used longer, or when an 
unspecified battery is used, liquid may leak from the battery, causing the 
remote control to malfunction.

•

  The recommendable effective period is printed on the battery. This may be 

shorter due to manufacturing time to the unit. However, the battery may still 
be in working order after expiry of its nominal life.

Pull out the cover.

Insert new batteries.
