38 | CHAPTER 4 – MAINTAINING YOUR SMART TABLE
Cleaning Your SMART Table
Use an alcohol-free household glass cleaner, such as Windex® glass cleaner, to
clean the surface at regular intervals.
IMPORTANT
Before you clean your SMART Table, turn it off (see page 6) so that you don’t
inadvertently start applications when you wipe the surface.
Replacing the Projector Bulb
The average life of a projector lamp is 2000 hours. When the projector lamp has been
used for 2000 hours or more, the following message appears on your SMART Table’s
surface:
It is time to replace the lamp. Use the procedure in the
User’s Guide to replace the lamp as soon as possible.
Contact your reseller (see page 51) for a replacement lamp as soon as possible. After
2100 hours of use, the following message appears on your SMART Table’s surface
for 10 seconds, and then the projector turns off:
The lamp has exceeded its service life! The projector will
not turn on until you replace the lamp.
NOTE
In some situations, the projector lamp may start to dim before 2000 hours of use.
Replace the projector lamp in these situations as well.
Refer to the document included with the replacement lamp for instructions.
