Alkaline Battery Installation
1. Remove battery compartment cover by loosening the bolt with a
coin. Remove the Ni-MH battery packs from the chambers inside
the battery compartment, making sure to disconnect the two-pin
connectors. Then, insert “C” alkaline batteries into the chambers,
noting polarity as shown on chamber bottoms or cover of battery
compartment.
Notes:
• When the battery case is filled with “C” alkaline batteries, the
power adapter should not be used to charge these batteries.
• Charging alkaline batteries can result in explosion.
• Used (discharged) batteries are hazardous waste and should be
disposed of properly.
Charging Ni-MH Rechargeable Batteries
1. Remove black rubber plug above the battery compartment cover
and insert the 6V battery adapter. Plug adapter into 115V AC wall
socket to begin charging. During the first charge of the batteries,
the charge indicator lamp is red. After 5 hours or so, the indicator
lamp will turn green showing that the battery pack has been fully
charged.
Notes:
(1) Even after battery pack appears to be full charged, we suggest
users continue to charge for 2 more hours to ensure the battery-
pack’s maximum charge capacity.
