PDISCHARGE (Ni-MH Batteries Only)
The capacity of rechargeable Ni-MH batteries may be temporarily reduced when new, after long periods of disuse, or if they are repeatedly recharged before being fully discharged. Capacity can be increased by repeatedly discharging the batteries using PDISCHARGE and recharging them in a battery charger (sold separately).
Q Do not use PDISCHARGE with non-rechargeable batteries.
