Inserting Batteries into the Remote Control
Before you can use the remote control, you must first insert the
supplied batteries. If you want to use this remote control to operate
your TV, cable box, VCR, or laser-disc player, you must also program
the remote, as described in the Appendix on page 79.
To install the batteries:
1
Push and slide open the battery compartment.
2
Insert two size AA batteries (supplied). Be sure to line up the +
and – on the batteries with the + and – on the battery
compartment.
Notes on Batteries
Y If the remote control does not operate properly, the batteries might
be worn out. When replacing batteries, replace both of them with
new ones, and do not mix different types of batteries together.
Y When you remove the batteries — to replace them, for example —
any codes you’ve set may be erased. If this happens, you must
reprogram the remote. See “Programming the Remote” on page 79
for details.
