9-2 Accessories
9.1.5 Power supply and
battery chargers
EHP-50F accessories are powered by either internal rechargeable
batteries or directly from other devices to which they are connected.
The AC/DC battery charger can be used with a power frequency at either
50 Hz or 60 Hz with a supply voltage between 100 and 240 AC Volt.
International AC plug adapters are provided according to the various
national standards.
AC plug adapter can be easily removed from the battery charger to be
replaced by a different one.
To have the greatest autonomy, a full recharging cycle should be carried
out before using the Accessories.
ALWAYS connect the battery charger to the mains BEFORE
connecting to the charge input of the accessories.
The battery charger has an internal protective circuit that will break
the output if any load is detected while connecting to the mains.
Battery charger:
output: DC, 10 - 15 V, ~ 500 mA
Connector:

In order to preserve battery efficiency a complete recharge cycle is
required before storing them for periods longer than 4 months.
Therefore, it is warmly suggested recharging the batteries at least
every 4 months even though the device has not been used.
Software and Firmware updates for Accessories can be downloaded
from the Web site http://narda-sts.it, http://narda-sts.de, or requested
directly from NARDA Sales Centres.
