MAINTENANCE
Case
Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do not use liquid or
aerosol cleaners.
4.3 Replacing Keypad Batteries
The optional IR Remote Keypad uses four AA size, 1.5V batteries (preferably alkaline). To install
new batteries, open the battery compartment at the back side of the keypad by pulling on the
raised portion of the cover as shown below.
Replacing Keypad Batteries
Remove the old batteries and properly discard. Wait a minute or two and place the new batteries
in the compartment, orienting the positive/negative of each battery according to the labels in the
compartment. When batteries are in place, replace the cover by inserting its bottom edge first and
snapping the top into place. Do not force.
NOTE: Always wait a minute or two when replacing batteries so that the internal electronics dis-
charge and can recognize the change.
NOTE: For this procedure you will need a VX-4c/VX-6c Lamp and Filter Replacement Kit from
Runco.
The high brightness of your projector is provided by a 700 watt Xenon lamp permanently mount-
ed inside its own protective housing. When the bulb approaches 1000 hours of usage, this lamp
assembly should be replaced.
How Old is The Lamp?
The number of hours logged on the current lamp appears both in the Lamp Adjust submenu
(accessed through the Advanced menu) and the Information menu. In the Information menu, do
not confuse “Xenon Lamp Hours” with “Projector Hours”, which indicates the number of hours
logged during the ‘rental period’, in a situation where the VX-4c/VX-6c is to be rented for vari-
ous functions. In a permanent install, this would be of no consequence.
NOTE: As the lamp nears its limit (as set in Lamp Limit), a message can appear on screen to
warn that the lamp needs to be replaced. To make sure that this warning appears, enter a check-
mark in the Lamp Message checkbox located in the Lamp Adjust submenu.
