Unpacking 
Power Supply Requirements 
The Zenith 140 can operate from AC supply or from a DC battery. The AC is 
either 85-120V 50/60Hz or 170-240V 50/60Hz, depending on the position 
of the selector switch. The DC is 18-36V. In all cases the Zenith 140 will 
typically consume 6W of power, with a maximum of 10W. 
   
Important Information 
All shipping cartons should be opened carefully. When using a box cutter, do not 
plunge the blade deeply into the box, as it could potentially cut or scratch 
equipment components. Carefully remove equipment from each carton, 
checking it against the packing list before discarding any packing material. If 
there is any shortage or obvious shipping damage to the equipment, report it 
immediately to Pulsar Process Measurement Limited.
