2-9 Change the lamp or put on the mirror
Before changing the lamp, first pull the plug out off the
electrical socket and wait for a while until the lamp cools
down to avoid being burnt. Loosen the door-screw on the
bottom to open the small door. Then you can see the lamp
and lamp holder. Pull the lamp out and insert a new one into
the holder. Close the door by tightening the screw.
While changing the mirror, screw off the base-lens or mirror
and screw on a new mirror.
