INSTRUCTIONS ON HOW TO RECHARGE THE BATTERY PACK » Dry the battery pack and lay it down on a table. » Loosen the four closing screws on the cover with the hexagonal wrench included in the probe accessories. » Pull the screws completely out and gently move the cover to one side of the battery pack. » Dry any trace of water in the proximity of the external side of the o-ring.

» Connect the battery charger to the top head connector. » Read the below “Battery Charger” instructions. » Put the cover on the battery pack. » Check the correct position of the o-ring and close the battery pack again with the four screws. » Gradually tighten the screws alternating one screw with another.

(DO NOT TIGHTEN EXCESSIVELY - PLASTIC POM HOUSING).

» It is enough that you tighten a quarter of a turn of the screw at
the end of stroke of the screw thread (plastic POM housing).

RECHARGEABLE BATTERY PACKS
BATTERY CHARGER

Connecting the battery pack, the charger immediately checks the nominal voltage thus automatically selecting
the most appropriate action to carry out as:
1. If the battery voltage is lower than 1.2 V x cell, the charger carries out the standard charging procedure
which implies the recharging at a moderate current for 30m. Whenever the battery reaches the nominal
voltage, the charger automatically starts the quick-charging procedure.
2. If the battery voltage is higher than 1.2 V x cell, the charger carries out the quick-charging procedure.
3. If the battery voltage is lower than 0.2 V x cell, the charger carries out the standard charging procedure
thus inhibiting the quick-charging procedure.

Note
At the end of the quick-charging procedure, the charger undertakes a low-current equilibration charging
procedure which lasts 30 m. This procedure is also called trickily-charging procedure. The aim of this procedure
is to keep the battery cells in good conditions thus compensating for the auto-discharge.
