BATTERY
The instrument uses a 3.6V non-rechargeable lithium-thionyl chloride (Li-SOCl
2
)
battery AA size. To connect the battery, or to replace a dead battery with a new one,
proceed as follows:
1. Unscrew the 4 screws on the back of the case and remove the back cover.
2. In case of replacement, disconnect the battery connector from the circuit board
and replace the battery with a new one of the same type.
3. Connect the battery connector to the circuit board, observing the correct polarity.
The connector is equipped with a polarization key that prevents the possibility of
a wrong insertion of the connector.
4. Close the case by fixing the 4 rear screws (pay attention to the correct placement
of the battery, not to hinder the closing of the case).
The battery symbol at the bottom left of the display lights up when the battery is low;
in this case, replace the battery as soon as possible.

INSTALLATION OF THE INSTRUMENT
The case of the instrument is provided with a hole on the back to fix it to a support
(screw or hook) on the wall. Insert the head of the support in the lower part of the
hole (width 10 mm) and lower the instrument so that the head of the support remains
wedged in the upper part of the hole (width 6 mm). Make sure that the instrument
cannot accidentally come out from the support.
Fixing hole
Alternatively, a fixed installation can be realized, using the optional HD208.13
aluminium flange to be fixed on the back of the instrument case.
