Insert the battery plug (in the corner, near the terminal for the optical
interface). The two pins should point towards the clip. Avoid touching the

10. Return the back of the unit (with the new battery in the case) to the front
panel with the components, taking care not to stretch the battery leads.
Carefully lower the back of the unit and make sure that it is aligned
correctly (the four cylindrical holes on the back must slip over the four
mounting pins on the front panel). Also make sure you do not pinch the
battery leads or other wires or components.

connection leads, and retighten the two screws at the bottom of the
case. Then put the battery back into the case.

NOTE: If the instrument is not used for long periods of time (more than 6
months), it is recommended, in order to recover the initial capacity of the
battery, to make several charge-discharge cycles (3 to 5 times). Discharge
cycle (15 H) can be made with the instrument in MANUAL mode, DC 2-Pole
(2-Pole) resistance measurement and a short-circuit between H (Z) and E (X)
plugs.
