IMPORTANT SAFETY INFORMATION

 

Do not operate your mixer in excessively humid conditions. Avoid excessive heat from sunshine, 

fire or similar. If your mixer is being used in a dusty environment, make sure it is adequately 

protected.

 

Avoid installing your mixer near any heat sources such as radiators, heat registers, stoves, or 

other heat-producing apparatus (including amplifiers). 

 

Do not put any sources of open flame (e.g. candles or pyrotechnics) on or near your mixer.

 

Do not cover your mixer during use, or obstruct the ventilation flow in any way.

 

Unplug your mixer during lightning storms, or if it is not going to be used for a while. (Remove 

the plug from the mains socket to completely disconnect the mixer.)

 

Your mixer does not contain any “user serviceable” parts. Servicing and/or repairs should only 

be carried out by qualified personnel. See MAINTENANCE AND REPAIR (below).

OPERATIONAL SAFETY

 

During installation or live performances, make sure that your mixer’s power supply cable cannot 

be walked on, tripped over or “pinched” – particularly at sockets, around waste bins etc. Also 

make sure that the power supply cable is not “stressed” at its point of connection to the mixer.

 

To avoid interference, do not install your mixer near power transformers, TV sets, RF transmitters, 

electric motors, or any other sources of electrical energy.

 

To avoid potential accidents, only use attachments, accessories and other equipment such as 

carts, stands, tripods, brackets or cases that are specified or recommended by the manufacturer, 

or sold with your mixer. 

 

Loud volume levels can cause irreparable damage to hearing, so avoid the following while using 

your mixer:

- acoustic feedback (never point microphones directly at a loudspeaker)

- high levels of distortion

- impulse noises (loud “pops”) that can occur when a device is switched on/off, connected to or 

disconnected from a system.

MAINTENANCE AND REPAIR

 

Your mixer can be carefully cleaned, as necessary, using a dry cloth. No water must be used.

 

When cleaning, do not use any solvents (such as acetone or alcohol). These could damage  the 

mixer’s finish and its labeling.

 

Visually check your mixer on a regular basis for any signs of wear and tear or damage, but do 

not attempt any kind of servicing or repair. 

 

If your mixer malfunctions, or has been damaged, e.g. if the power supply/cable or plug is 

damaged, liquid has been spilled or objects have fallen inside, the mixer has been exposed 

to rain or moisture, does not operate normally, or has been dropped, please call your nearest 

Schertler technical assistance centre. (For more information, contact us at the address on the last 

page of this manual.)
