Resetting lamp hours

It is a good idea to reset the lamp hours to zero when you install a new lamp. (See “Diagnostics: Hours” on page 107.) This is not absolutely neces- sary; it is just a way for you to keep track of lamp use.

How to maintain lamp life

There are some actions that can shorten lamp life:

•Turning off AC power when the lamp is on. (Turn off the lamp with the remote and let it cool until the fans stop; then turn off AC.)

•Turning a lamp on and off rapidly. (The lamp should be allowed to heat up fully before turning it off, at least three minutes.)
