Figure 4.1. Replacing Remote Batteries
The RPMX/RPMSP-D120U projector includes 2 100/120W UHP lamps and the
RPMSP-D275U projector includes two 275W UHP lamps; however, only one lamp
is operated at any given time. The other lamp is held in reserve until the user chooses
to switch lamps operation modes or a lamp fails. The projector's hot-swap feature
allows the lamp not in operation to be replaced without powering down the projector
and while the other lamp is still on. Although it is recommended the projector be
turned off during lamp replacement, this feature benefits those critical applications
where downtime must be kept to an absolute minimum.
When do I replace a lamp? Lamps that have shown a drastic reduction in
brightness or have reached their end of life (approx 10000 hours for D120U and 2250
hours for D275U) should be replaced immediately. You can check the number of
hours each lamp has been in use by looking up the number of
individual lamp submenus or in the Status menu. From the Lamp menu, you can also
set a and enable the projector to send a warning message when it's
LAMP LIMIT
powered on to indicate the lamps have reached their set limit.
