To Recharge the Ni-cad Battery Pack Out of the GP-01
The GP-01 battery pack may be recharged directly in the charger without
being in a GP-01. This capability is useful if you have spare battery packs.
The following instructions assume the battery pack is not in a GP-01.
1. Plug the power cord of the optional Ni-cad battery charging station into
an AC outlet.
2. Place the battery pack into the front part of the battery charging station
as shown in Figure 9 below so that the metal contacts on the battery
pack come into contact with the metal contacts in the front part of the
holder in the charging station. A label on the pack which reads “To
Charger” indicates which end to insert into the charger. When proper
contact has been made, the red LED on the charging station will turn
on.
