qualified service personnel.
WARNING:
To reduce the risk of fire or electric shock, do not expose the
RB-993 to moisture or water. Do not allow foreign objects to get
into the enclosure. If the unit is exposed to moisture, or a foreign
object gets into the enclosure, immediately disconnect the power
cord from the wall. Take the unit to a qualified service person for
inspection and necessary repairs.
Read all the instructions before connecting or operating the RB-993 . Keep this
manual so you can refer to these safety instructions.
Heed all warnings and safety information in these instructions and on the
product itself. Follow all operating instructions.
Clean the RB-993 only with a dry cloth or a vacuum cleaner.
Keep the ventilation inlets on the unit unobstructed. For example, do not place
the unit on a bed, sofa, rug, or similar surface that could block the ventilation
slots. If the RB-993 is placed in a bookcase or cabinet, there must be sufficient
clearance around the unit and ventilation of the cabinet to allow proper cooling.
Keep the RB-993 away from radiators, heat registers, stoves, or any other
appliance that produces heat.
The RB-993 must be connected to a power supply only of the type and voltage
specified on the rear panel of the unit.
Connect the RB-993 to the power outlet only with the supplied 2-pin polarized
power supply cable or an exact equivalent. Do not modify the supplied cable in
any way. Do not attempt to defeat grounding and/or polarization provisions. The
cable should be connected to a 2-pin polarized wall outlet, matching the wide
blade of the plug to the wide slot of the receptacle. Do not use extension cords.
Do not route the power cord where it will be crushed, pinched, bent at severe
angles, exposed to heat, or damaged in any way. Pay particular attention to the
power cord at the plug and where it exits the back of the unit.
The power cord should be unplugged from the wall outlet if the unit is to be left
unused for a long period of time.
Immediately stop using the RB-993 and have it inspected and/or serviced by a
qualified service agency if:
• The power supply cord or plug has been damaged.
• Objects have fallen into or liquid has been spilled into the unit.
• The unit has been exposed to rain.
• The unit shows signs of improper operation
• The unit has been dropped or damaged in any way
Place the RB-993 on a fixed, level surface strong
enough to support its weight. Do not place the
RB-993 on a moveable cart that could tip over.
