Replacing the Batteries in the Remote Control
The life of the batteries depends on how often and how long you 
use the remote. Symptoms of low battery charge include erratic 
responses when using the remote and a reduced range of opera-
tion.
Follow these steps to replace the batteries:
1
Turn the remote face down in your hand.
2
Slide the battery cover off the end of the remote.
3
Remove the old batteries and dispose of them in an environ-
mentally proper manner.
4
Install two new AAA alkaline batteries. Make sure you install 
each in the correct direction.
5
Slide the battery cover back on the remote.
Using the Security Lock 
The projector has a security connector for use with a PC Guardian 
Cable Lock System (Figure 23). See “Optional Accessories” on 
page 43
 for ordering information. Refer to the information that 
came with the lock for instructions on how to use it to secure the 
projector.
