Recharging the Battery Pack
When fully charged, the optional NiCd rechargeable battery pack can 
operate up to 40 Minutes.
To maintain optimum performance, the battery pack should always be 
completely exhausted (see next page), before any recharging is done. 
Otherwise, the battery life will become shorter.
