Before shipment, the instrument’s electronics and mechanics were inspected. All possible
precautions were taken to permit delivery of instrument free of damage. However, we
recommend generally inspecting the instrument in order to detect any damage suffered
during transport. Should you detect any anomalies, immediately contact the forwarding
agent or the dealer. Moreover, we recommend checking that the package contains all
parts listed in § 11.3. Should you find any discrepancy, please contact the dealer. Should it
be necessary to return the instrument, please follow the instructions reported in § 12.

The station unit HT2055S is power-supplied by 230V ± 10%, 50/60Hz mains while the
meter unit HT2055M is power-supplied through 6x1.2V IEC AA internal rechargeable
batteries which are recharged from the mains by means of a battery charger supplied as
standard accessory. The use of 6x1.5V type AA LR6 alkaline batteries is also possible for
this unit. The symbol “
