View of the two battery drawers. Each drawer holds one 9-volt battery. To open the battery drawer; press in and up. The catch will release and the drawer will spring backwards to open. Slide the drawer out. Insert battery following the polarity marks. Slide the drawer back in until it clicks. This locks the drawer closed.

 

We recommend using only Alkaline batteries as there is no charging provision for rechargable batteries. Their voltage is a little lower than Alkaline batteries and that will reduce performance a bit.

 

Battery life is estimated at six hours of continual use. We recommend that you use the optional wall supply and keep the batteries in so that if the wall supply cord gets kicked out, the batteries will automatically and silently operate the unit with no pops or interruptions.

 

 

 

 

Power Information: The HCIII gives you reverse polarity protection. The power input connector will accept AC or DC power-any polarity from 12 volts to 24 volts. Its internal steering diodes will fully protect the unit. You can leave the batteries in when you use a wall-type power supply. But always remove the batteries when you plan to store the unit and not use it for a while.
