4. PROJECTOR FEATURES CAUTIONS CONCERNING THE SETUP OF THE PROJECTOR For minimal servicing and to maintain high image quality, PHILIPS recommends that this projector be installed in an area free from humidity, dust and cigarettesmoke. If the projector is used in these environments, the lens and filter will need to be cleaned (or the filter replaced) more often, and internal cleaning may become necessary. As long as the projector is regularly cleaned, use in these environments will not reduce the overall operation life of the unit. Internal cleaning should only be performed by a Philips Authorised LCD Projector Dealer or Service Centre. NOTES ON OPERATION •The exhaust vent, the lamp cage cover and adjacent areas may be extremely hot during projector operation. To prevent injury, do not touch these areas until they have sufficiently cooled. TEMPERATURE MONITOR FUNCTION If the projector starts to overheat due to setup problems or a dirty air filter,'TEMP.' and ' ' will flash in the lower-left corner of the picture. If the temperature continues to rise,the lamp will turn off,the Temperature warning indicator (Temp.) on the projector will flash,and after a 90-second cooling-off period the power will shut off. Refer to 'Lamp / Maintenance Indicators' on pages 29-31 for details. Note: The cooling fan regulates the internal temperature, and its performance is automatically controlled. The sound of the fan may change during projector operation due to changes in the fan speed. LAMP MONITOR FUNCTION When the projector is turned on after the lamp has been used for 900 hours, 'LAMP' and ' ' will flash in the lower-left corner of the picture to advise you to replace the lamp. See pages 30 and 31 for lamp replacement. If the lamp has been used for 1,000 hours, the projector power will automatically turn off and the projector will enter the standby mode. Refer to 'Lamp/Maintenance Indicators' on page 29-31 for further details. •Allow at least 10 cm (4 inches) of space between the cooling fan (exhaust vent) and the nearest wall or obstruction. •If the cooling fan becomes obstructed, a protection device will automatically turn off the projector lamp. This does not indicate a malfunction. Remove the projector powercord from the wall outlet and wait at least 10 minutes. 104 F ('40 C) 41 F ('5 C) Then turn on the power by plugging the powercord back in. This will return the projector to the normal operating condition. 6
