8.

Do not install near heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

9.

Do not defeat the safety purpose of the polarized or the grounding-type plug. A polarized plug has two blades with one wider than the other.
A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. I the
provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10.

Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from
the apparatus.

11.

Only use attachments/accessories specified by the manufacturer.

12.

Use only with the cart, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to avoid injury from tip-over.

13.

Unplug this apparatus during lightning storms or when unused for a long period of time.

14.

Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-
supply cord or plug is damaged, liquid has been spilled or orbjects have fallen into the apparatus, the apparatus has been exposed to rain
or moisture, does not operate normally, or has been dropped.

15.

Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the
equipment.

16.

To completely disconnect this equipment from the AC Mains, disconnect the power supply cord plug from the AC receptacle.

17.

The mains plug of the power supply cord shall remain readily operable.

IMPORTANT SERVICE INSTRUCTIONS

CAUTION: These servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not

perform any servicing other than that contained in the Operating Instructions unless you are qualified to do so.
Refer all servicing to qualified service personnel.

1.

Security regulations as stated in the EN 60065 (VDE 0860 / IEC 65) and the CSA E65 - 94 have to be obeyed when servicing the appliance.

2.

Use of a mains separator transformer is mandatory during maintenance while the appliance is opened, needs to be operated and is
connected to the mains.

3.

Switch off the power before retrofitting any extensions, changing the mains voltage or the output voltage.

4.

The minimum distance between parts carrying mains voltage and any accessible metal piece (metal enclosure), respectively between the
mains poles has to be 3 mm and needs to be minded at all times. The minimum distance between parts carrying mains voltage and any
switches or breakers that are not connected to the mains (secondary parts) has to be 6 mm and needs to be minded at all times.

5.

Replacing special components that are marked in the circuit diagram using the security symbol (Note) is only permissible when using
original parts.

6.

Altering the circuitry without prior consent or advice is not legitimate.

7.

Any work security regulations that are applicable at the locations where the appliance is being serviced have to be strictly obeyed. This
applies also to any regulations about the work place itself.

8.

All instructions concerning the handling of MOS-circuits have to be observed

WEEE RECYCLING/DISPOSAL INSTRUCTIONS

The lightning flash with arrowhead symbol, within an
equilateral triangle is intended to alert the user to the
presence of uninsulated „dangerous voltage“ within the
product’s enclosure that may be of sufficent magnitude
to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintance (servicing) instructions in the
literature accompanying the appliance.

NOTE:

SAFETY COMPONENT (MUST BE REPLACED BY ORIGINAL PART)

The Wheelie Bin symbol found on the product or in the manual indicates that this product must not be dis-
posed of with other waste. It is in our category the manufacturer’s responsibility to properly dispose of their
