Important Safety Notices
Lead-Free Solder
This product is manufactured using lead-free solder as a part of a movement within the consumer
products industry at large to be environmentally responsible. Lead-free solder must be used in the
servicing and repair of this product.
• This product is manufactured using lead free solder. DO NOT USE LEAD BASED SOLDER TO
REPAIR THIS PRODUCT! The melting temperature of lead-free solder is higher than that of leaded
solder by 86 °F to 104 °F (30 °C to 40 °C). Use of a soldering iron designed for lead-based
solders to repair product made with lead-free solder may result in damage to the component and
or PCB being soldered. Great care should be made to ensure high-quality soldering when
servicing this product - especially when soldering large components, through-hole pins, and on
PCBs - as the level of heat required to melt lead-free solder is high.
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the
machine power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
3. If any adjustment or operation check has to be made with exterior covers off or open while the
main switch is turned on, keep hands away from electrified or mechanically driven components.
4. The machine drives some of its components when it completes the warm-up period. Be careful to
keep hands away from the mechanical and electrical components as the machine starts operation.
5. Use brackets that are strong enough to support the projector. The projector weighs about 2.2 kg
(4.85 lb.).
6. The projector must be installed in a location that is sturdy enough to support the full weight of the
projector and brackets.
