FORD 2002 E-450 v.1 - Manual (Page 62)

The remote control unit uses two AAA batteries.
The need for battery replacement is usually indicated if the remote
control only functions at extremely close distances to the entertainment
center or not at all.
When replacing batteries, use two new batteries (alkaline recommended)
and install with correct orientation (+ and − polarities). Ensure that you
use only new batteries of the same brand.
If you will not be using the remote control for a considerably long time,
remove the batteries.
