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 FHS1D02/03 are as follows:
5
Main unit
Quality Check Report
4pcs of AAA Battery
Carrying Case
User's Guide
FC/PC(ST/PC, SC/PC optional)
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.

The instrument is power supplied by 4pcs of AAA battery ,and when you use the
battery, the battery indicator on the screen will show the remaining charge. An empty
battery indicator means the power is almost out. When the battery charge is
extremely low to supply the necessary power, the instrument will automatically switch
off . Please change the battery.
