4.1 Unpacking the instrument
Packing material
We suggest that you keep the original packing material. Using the original packing material is your
guarantee of protecting the instrument during transit.
Checking the package contents
The standard accessories of FHP2 are as follows:
FC, SC interchangeable connector, Manual, Carrying Bag, Software (CD), USB cable, AC/DC adapter,
Test Report.
Optional accessories:
Checking for damage in transit
After unpacking the instrument, check to see whether it was damaged in transit. This is particularly likely
if the outer casing is clearly damaged. If there is damage, do not attempt to operate the instrument or to
repair it without authorization. Doing so can cause further damage and you may lose your warranty
qualification.

4.2 Discharged batteries
There is a battery indicator on the screen to show the remaining charge. There are four possibilities the
indicator may show, full, with 2 blacks, with 1 black and empty. If an empty battery indicator flashes it
means the power is almost out, and that is when you should recharge the batteries by connect the AC
adapter with the instrument. If the discharged batteries get to their limitations after long-time use,
please replace it with a new one. To replace the batteries, please remove the battery plate on the back
of instrument with a screwdriver.
When the battery charge is extremely low to supply the necessary power, the instrument will
automatically switch off.
Note: 1 The AC indicator is not displayed when power is supplied by battery.
2 To eliminate the possibility of acid leakage, please take out the battery if the unit is not used for a long
time.

4.3 AC operation
If the instrument is mainly used at one location, e.g. in a laboratory or test department, the AC adapter
can be used to power it instead of batteries. The USB cable of the AC adapter is plugged into the USB
port. And when the AC adapter is plugged in, the Charging Indicator on the LCD will be
displayed.
Note:
1 Power is supplied by the AC adapter even if battery is fitted. And the battery indicator is not displayed
on the screen when AC adapter is plugged.
2 Make sure that the operating voltage of the AC Adapter / Charger is the same as the local AC line
voltage.
