SAFETY INSTRUCTIONS

General inst ructions

To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture, direct

sunlight or excessive heat from sources such as radiators or spotlights. No user serviceable parts are in-

side. Repair and maintenance must be carried out by qualified personnel authorized by MUTEC GmbH!

The unit has been designed for operation in a standard domestic environment. Do NOT expose the unit

and its accessories to rain, moisture, direct sunlight or excessive heat produced by such heat sources as

radiators or spotlights! The free flow of air inside and around the unit must always be ensured.

Initi al operati on

Prior to t he initial op eration of th e unit, the appliance, i ts access ories and p ackaging mu st be

inspe cted for a ny signs of phy sical dama ge that may have o ccurred du ring transi t. If the uni t has

been da maged mec hanically o r if liquids ha ve been spilled inside t he enclosure, the appli ance may

not be co nnected t o the mains or mu st be disco nnecte d from the main s immediat ely! If the un it is

damag ed, please do NOT return i t to MUTEC Gmb H, but noti fy your deal er and the shi pping com-

pany immediately, o therwise claims for d amage or rep lacement m ay not be grant ed.

If the device is left in a low-temperature environment for a long time and then is moved to a room-

temperature environment, condensation may occur on the inside and the exterior. To avoid short-

circuits and flashovers, be sure to wait one or two hours before putting the device into operation.

Power su pply

The device contains a self-adapting wide-range power supply supporting the majority of global stan-

dard line voltages within a range of 90…250 V, with no need for making adjustments. Make sure that

your line-voltage source provides a supply voltage within the specified range. In addition, make sure

that the device is properly grounded via the local electric installation.

Pleas e use the encl osed powe r cord (see p ackaging) to connect t he unit to the ma ins. Switc h the

unit of f before you a ttempt to connect it t o the mains. C onnect th e power cord to t he unit, the n

to a standard 3-pin mains outl et. To draw the po wer cord, ne ver pull on the c able but on th e mains

plug!

The uni t must be grou nded durin g operation!

For information on the power-inlet wiring, refer to the »Wirin g of connec tors« section in the

appendix. Disconnect the device from the mains when not using it for an extended period!

This symbol, an exclamation mark inside a triangle,

alerts you to important operating or safety instructions

in this manual.

This symbol, a flash of lightning inside a triangle, alerts

you to the presence of uninsulated dangerous voltage

inside the enclosure - voltage that may be sufficient to

constitute a risk of shock.

Decla ration of Conformity

We herewith confirm that the product complies with the European

Commission’s standards on electromagnetic compatibility.

Interference emission: EN 50081-1, 1992

Resistance to interference: EN 50082-1, 1992

Presupposed as operation condition is that all clock outputs are con-

nected with high-quality and good shielded BNC 75 ohms cable.

MUTEC GmbH warrants the flawless performance of this product to the original buyer for a period of two (2) years from the date of purchase. If any failure occurs within

the specified warranty period that is caused by defects in material and/or workmanship, MUTEC GmbH shall either repair or replace the product free of charge within 90

days. The purchaser is not entitled to claim an inspection of the device free of charge during the warranty period. If the warranty claim proves to be justified, the product

will be returned freight prepaid by MUTEC GmbH within Germany. Outside Germany, the product will be returned with the additional international freight charges payable

by the customer. Warranty claims other than those indicated above are expressly excluded.

§2 Warranty tra nsferability

This warranty is extended exclusively to the original buyer who bought the product from a MUTEC GmbH specialized dealer or distributor, and is not transferable to anyone

who may subsequently purchase this product. No other person (retail dealer, distributor, etc.) shall be entitled to give any warranty promise on behalf of MUTEC GmbH.
