You can use your computer mouse and keyboard along with your
electronic pen any time you like. Use whatever combination of
devices that best suits your applications and style.
Conserving Your Projector Lamp
The projector lamp is a relatively costly expendable item. You may
want to establish a regular practice of turning off the lamp when your
IRP 4100, 4500, or 5100 is not actually being used, even though you
leave the system on as a whole.
For the IRP 4500, do not use the Projector Power switch on the
control panel to turn off the projector lamp as a rule. Although this
will work, it may in fact reduce the lamp life because the projector
cooling fans would be turned off at the same time.
IRP 4500 Fuse Replacements
A replaceable fuse (10 amp, T10A/250V 5x20 mm, slow blow) is
located in the console power entry module just beneath the power
connector. If your power indicator light does not come on and
everything else appears to be in order, you should check this fuse.
In addition, the internally provided speaker cable inside the left front
compartment includes an in-line fuse from its power source (2 amp,
AGC ¼" x 1¼").
