GENERAL SAFETY PRECAUTIONS 
The equipment described in this manual has been designed in accordance with EN61010 "Safety 
requirements for electrical equipment for measurement, control and laboratory use", and has been 
supplied in a safe condition. To avoid injury to an operator or service technician the safety precautions 
given below, and throughout the manual, must be strictly adhered to, whenever the equipment is 
operated, serviced or repaired. For specific safety details, please refer to the relevant sections within 
the manual. 
The equipment is intended solely for electronic measurement and should be used for no other purpose. 
SIGNAL RECOVERY accepts no responsibility for accidents or damage resulting from any failure to 
comply with these precautions. 
Grounding 
To minimize the hazard of electrical shock, it is essential that the equipment be connected to a 
protective ground through the AC supply cable.  The continuity of the ground connection should be 
checked periodically. 
AC Supply Voltage  
Never operate the equipment from a line voltage or frequency in excess of that specified.  Otherwise, 
the insulation of internal components may break down and cause excessive leakage currents. 
Fuses 
Before switching on the equipment check that the fuses accessible from the exterior of the equipment 
are of the correct rating. The rating of the AC line fuse must be in accordance with the voltage of the 
AC supply. 
Should any fuse continually blow, do not insert a fuse of a higher rating.  Switch the equipment off, 
clearly label it "unserviceable" and inform a service technician. 
Explosive Atmospheres 
This equipment must NEVER BE OPERATED in a potentially explosive atmosphere. The equipment is 
NOT designed for use in these conditions and could possibly cause an explosion.
