Passeq

Please note and retain this information. Carefully read and follow all of the safety and oper-
ating instructions before you use the machine. Be doubly careful to note and follow the warn-
ings and special safety notices.

Connections: 

Only use the connections as described. Other connections can lead to health 

risks and equipment damage.

Water and Humidity:

 Do NOT use this machine anywhere near water (for example near a wash 

basin or bath, in a damp cellar, near swimming pools, or the like). In such cases there is an 
extremely high risk of fatal electrical shocks!

Insertion  of  Foreign  Objects  or  Fluids: 

NEVER  allow  a  foreign  object  through  any  of  the 

machine‘s chassis openings. You can easily come into contact with dangerous voltage or cause 
a damaging short circuit. NEVER allow any fluids to be spilled or sprayed on the machine. Such 
actions can lead to dangerous electrical shocks or fire! 

Opening  the  Machine:

  Do  NOT  open  the  machine  housing,  as  there  is  great  risk  you  will 

damage the machine, or – even after being disconnected – you may receive a dangerous elec-
trical shock!

Electrical Power:

 Run this machine ONLY from sources which can provide proper power at the 

prescribed rating. When in doubt about a source, contact your dealer or a professional electri-
cian. To be sure you have isolated the machine, do so by disconnecting the power cord from 
your wall connection. Be sure that the power cord plug is always accessible. When not using 
the machine for a longer period, make sure to unplug it from your wall power socket. 

Power Cord Protection:

 Make sure that your power cord is arranged to avoid being stepped 

on or any kind of crimping and damage related to such event. Do not allow any equipment or 
furniture to crimp this power cord.

Power  Connection  Overloads: 

Avoid  any  kind  of  overload  in  connections  to  wall  sockets, 

extension or splitter power cords. Always keep manufacturer warnings and instructions in 
mind. Overloads create fire hazards and risk of dangerous shocks!

Lightning: 

Before thunderstorms or other severe weather, disconnect the machine from wall 

power (but to avoid life threatening lightning strikes, not during a storm). Similarly, before 
any severe weather, disconnect ALL the power connections of other machines and antenna 
and phone/internet cables which may be interconnected so that no lightning damage or over-
load results from such secondary connections.

Air  Circulation: 

Chassis  openings  offer  ventilation  and  serve  to  protect  the  machine  from 

overheating. NEVER cover or otherwise close off these openings. NEVER place the machine 
on a soft surface (carpet, sofa, etc.). Make sure to provide for a mounting space of 4-5 cm/2 
inches when mounting the machine in racks or cabinets.

Repairs: 

Unplug the machine and immediately contact a qualified technician when you think 

repairs are needed – or when moisture or foreign objects may accidentally have gotten in to 
the housing, or in cases when the machine may have fallen and shows any sign of having been 
damaged. This also applies to any situation in which the machine has not been subjected 
to  any  of  these  unusual  circumstances  but  still  is  not  functioning  normally  or  its  perfor-
mance is substantially altered. 

 

 

 

 

 

 

In cases of damage to the power cord or its plug, first consider turning off the main circuit 
breaker before unplugging the power cord.  

 

 

 

 

 

Operate the controls and switches only as described in the manual. Incorrect adjustments 
outside safe parameters can lead to damage and unnecessary repair costs. Never use the 
switches or level controls to effect excessive or extreme changes. 

Replacement/Substitute Parts:

 Be sure that any service technician uses original replacement 

parts or those with identical specifications as the originals. Incorrectly substituted parts can 
lead to fire, electrical shock, or other dangers, including further equipment damage. 

Safety inspection:

 Be sure always to ask a service technician to conduct a thorough safety 

check and ensure that the state of the repaired machine is in all respects up to factory stan-
dards.

Cleaning: 

In cleaning, do NOT use any solvents, as these can damage the chassis finish. Use 

a clean, dry cloth (if necessary, with an acid-free cleaning oil). Disconnect the machine from 
your power source before cleaning.
