Warning

PULSE III

VERY IMPORTANT

Before connecting your new Leema amplifier to the rest of your system, please ensure that the loudspeaker cables are 
correctly and firmly attached to the binding posts on the rear of the unit. All required sources should also be connected 
BEFORE  inserting  the  mains  power  lead  and  powering  for  the  first  time.  Although  the  Pulse  III  amplifier  has  short-circuit 
protection, shorts should be avoided to reduce the stress on the amplifier. 

User installation and safety advice

Please ensure that the mains voltage of your new Pulse III amplifier is correct for your region. The setting is displayed on a label 
below the mains power inlet. The mains voltage setting is not user adjustable, therefore the amplifier must be returned to the 
manufacturer if any changes are required.

Ensure the mains supply is switched off at the wall socket, or unplugged before installing or moving the amplifier.

Do not use near water, for example do not place a potted plant on top of the unit or allow drinks to be placed near the unit. If 
liquid is spilt in to the cabinet, remove the mains lead from the wall immediately. The amplifier should then be returned to your 
dealer for safety testing before re-use. Failure to do so may result in electric shock or even fire! Do not use the amplifier in 
damp conditions, e.g. outside of the house.

Keep away from direct sunlight and other heat sources and ensure adequate ventilation around the amplifier to maintain 
proper cooling. Units 

MUST NOT

 be stacked directly on top of each other.

Never attempt to open the cabinet. There are no user adjustable parts inside and doing so will invalidate the amplifier’s 
warranty.

In the event of an electrical storm, remove the mains power lead from the wall outlet.
