Do not open (or modify in any way) the unit.
Do not attempt to repair the unit, or replace parts within it (except when this manual provides
specific instructions directing you to do so).
Never use or store the unit in places that are: Subject to temperature extremes (e.g., direct sunlight
in an enclosed vehicle, near a heating duct, on top of heat-generating equipment); or are damp
(e.g., baths, washrooms, on wet floors); or are humid; or are exposed to rain; or are dusty; or are
subject to high levels of vibration.
When using the unit with a rack or stand, the rack or stand must be carefully placed so it is level
and sure to remain stable. If not using a rack or stand, you still need to make sure that any location
you choose for placing the unit provides a level surface that will properly support the unit, and keep
it from wobbling.
Do not allow any objects (e.g., flammable material, coins, pins); or liquids of any kind (water, soft
drinks, etc.) to penetrate the unit.
Protect the unit from strong impact. (Do not drop it!)
Keep any caps you may remove and the included wing bolts in a safe place out of children’s reach,
so there is no chance of them being swallowed accidentally.
At regular intervals, you should unplug the power cord and clean it by using a dry cloth to wipe all
dust and other accumulations away from its prongs. Also, disconnect the power plug from the power
outlet whenever the unit is to remain unused for an extended period of time. Any accumulation of
dust between the power plug and the power outlet can result in poor insulation and lead to fire.
Try to prevent cords and cables from becoming entangled. Also, all cords and cables should be placed
so they are out of reach of children.
Never climb on top of, nor place heavy objects on the unit.
Never handle the power cord or its plugs with wet hands when plugging into, or unplugging from,
an outlet or this unit.
Before moving the unit, disconnect and all cords coming from external devices.
Before cleaning the unit, turn off the power and unplug the power cord from the outlet.
Whenever you suspect the possibility of lightning in your area, disconnect the cables from the outlet.
