Attention 
Lamp life is a measure of brightness degradation only, and is not a 
specification for the time it takes a lamp to fail and cease light output. Lamp 
life is defined as the time it takes for 50% of a lamp sample population to 
decrease in brightness by 50% of the rated lumens for the specified lamp. For 
example, if a sample of lamps are rated as 1500 lumens and 2000 hours of 
Lamp life, then after 2000 hours, 50% of the sample will experience a 
brightness decrease of 50% to 750 lumens. 
Using the security slot 
The projector has a security slot, (see Figure 1-4 on page 1-3). Refer to the 
information that comes with the lock for instructions on how to use it.
