The charger requires minor assembly before it can be used.  The distribution cable is packed 
separately from the charger and must be connected to the terminals of the charger before use.  
You will need a Philips head screwdriver for assembly.  Follow these steps: 

 

1.  Identify the polarity of the terminals on the 

cable as well as on the charger (see photos 
on right).

 

2. Unscrew the terminal screws slightly and 

insert the terminal forks 

underneath

 the 

square washers. 

3.  Tighten the terminal screws with moderate 

force.  Do not overtighten. 

4.

 

Put the plastic cap over the screw terminals to 
prevent an accidental short.  If the polarity is 
reversed, the cap will not fit properly.

 

 

Do not connect charger with incorrect polarity to the dAck!, as this 

will degrade and ultimately destroy the power cells. 

 
 
 

Place the dAck! on a stable support surface in a secure location where it will not be 

bumped into or knocked over.  As with any high-fidelity equipment, a good support surface may 
improve its performance by isolating it from external vibrations.  Do not place any equipment or 
small items on top of the dAck!’s vent holes.  If you would like to prevent dust from entering the 
chassis, it is OK to cover the unit with a light cloth when not in use. 
 
 

Familiarize yourself with the dAck!’s inputs, outputs, and controls.  The following 

figures show the important features and their purposes.
