SETUP AND USE GUIDE 3
USING THE AVIDEA REMOTE
The Batteries
The Avidea Remote requires 3 AA-batteries (3 x 1.5 V) to function.
You can use either the supplied batteries or purchase rechargeable batteries.
1 Remove the battery cover by releasing the tab and lifting.
2 Install the batteries in the battery compartment.
3 Replace the battery cover.
After a few seconds, the Avidea Remote starts up automatically and beeps
twice to indicate that it is ready for use.
Note: Do not touch the screen or hard buttons during start up as this may cause your
remote to lock up. If it does lock up, remove one battery and start again.
