replaCIng the Internal CloCk battery
This projector has an internal clock that uses a battery. When the clock of the network
function does not work correctly, replace the battery.
1. Turn off the projector, and unplug the power cord.
Allow the projector to cool sufficiently.
2. After making sure the projector has cooled
adequately, slowly turn over the projector so that the
bottom is facing.
3. Turn the battery cover fully in the direction indicated
“OPEN” using a coin or the like, and pick the cover
up to remove it.
4. Pry up the battery using a flathead screwdriver or the
like to take it out. While prying it up, lightly put a finger
on the battery since it may pop out of the holder.
5. Replace the battery with a new one. Slide the
battery in under the plastic claw, and push it into the
holder until it clicks.
6. Replace the battery cover in place, then turn it in the
direction indicated “CLOSE”.

The internal clock will be initialized by removing the battery.
