ROLONGING BATTERY LIFE
The battery can be charged and discharged hundreds of times, but its capacity diminishes with
use. The battery life can be prolonged with a few practical measures:
•
When first using the device, make a complete charge of the battery.
•
From time to time, make a complete cycle of discharging and recharging.
•
Do not leave the battery discharged for a long period.
•
Do not discharge the battery below the minimum threshold: recharge the battery when
the battery symbol on the display reaches the minimum level.
•
Do not expose the battery to extreme temperatures.

EPLACING THE BATTERY
When the battery capacity is heavily reduced, it is necessary to replace it. To replace the bat-
tery proceed as follows:
1.
Disconnect the external power supply unit or the PC, if connected.
2. Remove the protective rubber shell, if any.
3. Untighten the 4 screws securing the battery compartment cover on the back of the instrument.
4. Remove the battery.
5. Remove the connector paying attention not to tear the wires away.
6. Attach the connector to the new battery: the connector has a reference which prevents an
erroneous insertion.
7. Place the battery in its housing.
8. Close the battery compartment with the 4 fixing screws.
