Garmin 74C 用户手册

Before using the remote control, pull out the tape from the battery 
tray as shown below.

When the battery power runs low, you can replace it as described on 
page 44.

Most of the projector’s features can be accessed only with the remote 
control. To prevent losing it, store it in the projector’s remote control 
storage compartment when you are not using it.
