11 Maintenance
Periodic maintenance is needed to ensure proper operation over time. Most important is to maintain an air-
conditioned, low-ambient temperature and low-particle environment.
11.1 Safety
Regularly inspect the mechanical mounts to ensure that the unit is safely in its intended position and securely
fastened.
NOTE! It is advised that all installations operate a maintenance plan to ensure safety.
WARNING! A projector that is not securely positioned and fastened in an installation poses a potential
risk of harming people. It is the responsibility of the system owner to make sure safety is a priority.
11.2 Cleaning
Vacuum the projector air inlets and outlets on a regular basis to avoid clogging of the ventilation system and to
maximize cooling.
NOTE! Low system temperatures are imperative for long lasting operation. A symptom of bad ventilation is
high audible noise from the cooling fans, which could result from high ambient temperatures and clogged
vents.
Use a damp cloth without detergent to wipe off any dust on the unit.
NOTE! Do not spray water or detergent directly on to the projector, as liquids may enter the inside of the
unit. This would void any warranties and could cause damage to the unit and result in a potential
personnel safety risk.
11.3 Calibration
The brightness of the projector will reduce over time. It is therefore advised to check the system performance
and recalibrate if needed.
11.4 Software Updates
New projector software may be available from time to time. The projector can be updated via the USB 2.0 port
on the Connections Panel (refer to section 8.5 of this User Guide).
Follow these steps to upgrade the projector:
1. Copy / paste the folder contents of the latest software update (‘cksum.txt and p1_software.tar.gz’) to
the root directory of a FAT file system formatted USB memory stick.
NOTE! Projector software version is identified by root folder name (i.e. ‘P1 Software V2.00’). The
software update within always has the title ‘p1_software.tar.gz’.
2. Insert the USB memory stick in to the USB port at the rear of the projector whilst it is turned on (can be
in standby or running).
3. Observe the LCD panel adjacent to the projector keypad and wait for the message ‘remove USB stick’
(message may vary slightly if the currently installed software version is old).
4. Remove the USB memory stick.
5. Observe the LCD panel adjacent to the projector keypad and wait for the message ‘standby’ which
signifies that the projector is updated and ready to be switched on.
NOTE! The software upgrade process can take up to 40 minutes to complete.
