Important safeguards
1 Read instructions - All the safety instructions for use 
should be read before the system is operated.
2 Retain instructions - The safety instructions and 
instructions for use should be retained for future 
reference.
3 Heed warnings - All warnings on the unit and in the 
operating instructions should be adhered to.
4 Follow instructions - All operating instructions and 
instructions for use should be followed.
5 Cleaning - Unplug system units from the mains outlet 
before cleaning. Do not use liquid cleaners or aerosol 
cleaners. Use a damp cloth for cleaning.
6 Attachments - Do not use attachments not 
recommended by the product manufacturer as they may 
cause hazards.
7 Water and Moisture - Do not use this unit near water, for 
example near a bathtub, washbowl, kitchen sink, or 
laundry basket, in a wet basement, near a swimming 
pool, in an unprotected outdoor installation or any area 
which is classified as a wet location.
8 Accessories - Do not place this unit on an unstable stand, 
tripod, bracket or mount. This unit may fall, causing 
serious injury to a person and serious damage to the 
unit. Use only a stand, tripod, bracket or mount 
recommended by the manufacturer, or sold with the 
product. Any mounting of the unit should follow the 
manufacturer's instructions, and should use a mounting 
accessory recommended by the manufacturer. An 
appliance and cart combination should be moved with 
care. Quick stops, excessive force, and uneven surfaces 
may cause the appliance and cart combination to 
overturn.
9 Ventilation - Openings in the enclosure, if any, are 
provided for ventilation and to ensure reliable operation 
of the unit and to protect it from overheating. These 
openings must not be blocked or covered. The unit 
should not be placed in a built-in installation unless 
proper ventilation is provided or the manufacturer's 
instructions have been adhered to.
10 Power sources - Units should be operated only from the 
type of power source indicated on the marking label. If 
you are not sure of the type of power supply you plan to 
use, consult your appliance dealer or local power 
company. For units intended to operate from battery 
power, or other sources, refer to the "Installation and 
User Instructions".
11 Grounding or polarisation - This unit may be equipped 
with a polarised alternating current line plug (a plug 
having one blade wider than the other). This plug will fit 
into the power outlet only one way. This is a safety 
feature. If you are unable to insert the plug fully into the 
outlet, try reversing the plug. If the plug still fails to fit, 
contact your electrician to replace your obsolete outlet. 
Do not defeat the safety purpose of the polarised plug. 
Alternatively, this unit may be equipped with a 3-wire 
grounding type plug having a third (grounding) pin. 
This plug will only fit into a grounding-type power 
outlet. This is a safety feature. If you are unable to insert 
the plug into the outlet, contact your electrician to 
replace your obsolete outlet. Do not defeat the safety 
purpose of the grounding-type lug.
12 Power-Cord Protection - Power supply cords should be 
routed so that they are not likely to be walked on or 
pinched by items placed upon or against them, paying 
particular attention to cords and plugs, convenience 
receptacles, and the point where they exit from the 
appliance.
13 Overloading - Do not overload outlets and extension 
cords as this can result in a risk of fire or electrical shock.
14 Object and Liquid Entry - Never push objects of any 
kind into this unit through openings as they may touch 
dangerous voltage points or short-out parts that could 
result in a fire or electric shock. Never spill liquid of any 
kind on the unit.
15 Servicing - Do not attempt to service this unit yourself as 
opening or removing covers may expose to dangerous 
voltage or other hazards. Refer all servicing to qualified 
service personnel.
16 Damage Requiring Service - Unplug the unit from the 
outlet and refer servicing to qualified service personnel 
under the following conditions: 
When the power-supply cord or plug is damaged.
If liquid has been spilled, or objects have fallen into 
the unit.
If the unit has been exposed to rain or water.
If the unit does not operate normally by following 
the instructions for use. Adjust only those controls 
that are covered by the instructions for use, as an 
improper adjustment of other controls may result in 
damage and will often require extensive work by a 
qualified technician to restore the units to their 
normal operation.
If the unit has been dropped or the unit has been 
damaged.
When the unit exhibits a distinct change in 
performance; this indicates a need for service.
17 Replacement Parts - When replacement parts are 
required be sure the service technician has used 
replacement parts specified by the manufacturer or parts 
which have the same characteristics as the original part. 
Unauthorised substitutions may result in fire, electric 
shock or other hazards.
18 Safety Check - Upon completion of any service or 
repairs to the units, ask the service technician to perform 
safety checks to determine that the unit is in proper 
operating condition.
19 Lightning - For added protection of the units during a 
lightning storm, or when it is left unattended and unused 
for long periods of time, unplug it from the wall outlet 
and disconnect the cable system. This will prevent 
damage to the unit due to lightning and power-line 
surges.
