12. Storage and maintenance
12.1. Handling the device
When the projector is not in use, protect it with the cover provided by the manufacturer.
Do not touch any of the optical parts with your fingers and avoid exposing any parts to dust. The dust accumulated on
any optical part of the device is to be removed using a brush or a bellows. Should you notice a finger smear or trace
of grease on an optical part, apply an alcohol-based cleanser and wipe with a lens cloth or gauze.
If the projector surfaces are dirty, take the precaution of cleaning them with a dry cloth. For marks that are
difficult to remove, we recommend using a damp cloth or neutral detergent.
Avoid employing organic solvents as these would damage the paint coating of the device.
If the projector remains idle for awhile, unplug the power supply cable.
Also, if the projector remains idle for awhile, remove the batteries from the remote control.
12.2. Replacing a fuse
3- Unplug the power supply cable (8) to avoid any risk of electrical discharge.
4- Remove the fuse holder (9), then replace the fuse.
If you are not using the appropriate fuse, the device will tend to easily malfunction or potentially cause an
accident. Only use the prescribed fuse (250 V, 2 AT).
The fuse holder contains two fuses. Since you cannot visually identify the defective fuse, remove both and test
them individually.
Anticipate other problem sources should the device continue to malfunction following replacement of the fuse.
Immediately unplug the power supply cable and contact the closest product retailer.
12.3. Replacing batteries on the remote control
Pull on the battery compartment lid, then remove the used batteries and replace them with new ones. Position the
new batteries as indicated on the sticker at the bottom of the battery compartment. Use two non-corrosive batteries
in order to avoid leaks (x 2 UM-4 alkaline batteries).
13. Trouble-shooting
Be sure to check each of the following elements before bringing the device in for repairs. If, once these elements
have been verified, the instrument is still not functioning properly, contact your product retailer.
4- The lamp does not light up when the main switch (7) is turned on.
Cause 1: Poor connection of the power supply cable
Place the switch on the "0" position and then firmly plug in the power supply cable (8).
Cause 2: The fuse has blown.
Replace the fuses (see 5.3 – Replacing a fuse).
