Battery recharging
The battery must be charged before using it for the first time because it is delivered with an energy content as low as possible.
Insert the battery into the charger and plug the adapter into an AC power supply.
Once charged, insert the battery into the side cover slot of the Zoom25/50 instrument and switch on.
Open the battery compartment (1) and remove the battery holder. Remove the battery from the battery holder (2).

Insert the new battery into the battery holder (3), ensuring that the contacts are facing outward. The battery should click into position. Insert the battery holder back into the battery compartment (4).
