! Caution

Safety Instructions – which must be strictly observed

Hazardous Environments

Do not operate the analyzer in hazardous environments. This equipment is intended to be used for maintenance, research, evaluation,
simulation and other analytical or scientific applications in areas such as industrial plants, public utilities, hospitals, universities,
laboratories, automotive service centers and electronic repair shops. We are not liable for any problems resulting from the use of the
analyzer in hazardous environments and misuse.

Care and Safety
To clean the analyzer, use a soft cloth dampened with water. Do not use cleaners or solvents because they can harm the body of the
unit and leak inside, causing permanent damage. Do not submerge the unit in water or use it on a wet environment. If the unit gets wet,
turn it off and remove the battery immediately. Dry the battery and the battery compartment with a soft cloth to minimize potential water
damage. Allow the unit to fully dry before installing the battery or using the units.

Li-ion Battery Operation / Wasting
Dispose of battery in the proper manner, according to federal, state and local regulations that apply in your area. A battery may leak
electrolyte if it is mixed with a set with different battery types, if inserted incorrectly, if disposed of in fire, or if an attempt is made to
charge a battery not intended to be charged. Discard leaky batteries immediately. Leaking batteries can cause skin burns or other
personal injury.

• Lithium-Ion batteries are subject to disposal and recycling regulations that vary by country and region. Always check and follow
your applicable regulations before disposing of any battery.

• Many countries prohibit the disposal of waste electronic equipment in standard waste receptacles.

• Place only discharged batteries in a battery collection container. Use electrical tape or other approved covering over the battery

connection points to prevent short circuits.

Warning !

The use of this device may be subject to national restrictions or regulations. Check your local authority or dealer before purchasing and
using this product.

User Information
In accordance with 13 of the Legislative Decree of 25th July 2005, no. 15 ”Implementation of Directives 2002/95/EC, 2002/96/EC and
2003/108/EC, relative to reduction of the use of hazardous substances in electrical and electronic equipment, in addition to waste
disposal”. The crossed bin symbol shown on the equipment indicates that at the end of its working life the product must be collected
separately from other waste. The user must therefore take the above equipment to the appropriate differentiated collection centers for
electronic and electro technical waste, or return it to the dealer when purchasing a new appliance of equivalent type, in a ratio of one to
one. Appropriate differentiated waste collection for subsequent recycling, treatment and environment-friendly disposal of the discarded
equipment helps to prevent possible negative environmental and health effects and encourages recycling of the component materials of
the equipment. Illegal disposal of the product by the user will be punished by application of the administrative fines provided for by the
legislative decree no. 22/1997 (50 and following of the legislative decree no. 22/1997).

• The USB connection is required if you prefer to use power

(+5V/USB) and communication to the PC via USB cable
(included in the package).

! Caution

DO NOT Use Any Voltage Source Not Specified Herein

• When connecting the analyzer via the USB cable, you need
to install the FTDI drivers at the time of first use. A pop up
window will ask for a new USB driver device. Have the PC
search for them in the CD-ROM under the directory FTDI and
complete the installation process tas instructed. Next go to
the Control Panel → System and search in Hardware for a
newly added COM port. Record the number of the new COM
port which will be used in the miniVNA PRO software set-up
later on.

• The Power-On is used to supply the analyzer from the
internal battery or when the USB is connected to the PC to
charge the battery till the charge led is ON. If the unit is
battery operated, it is mandatory to use the Bluetooth to
communicate with the PC. The battery has a capacity of 1000
mAh and the charging time is about 3 hours. The PC must
also be Blue-tooth capable to use the wireless feature.

• The extension connector type RJ45 is used for connection
to future product.

• The reset switch is relevant to the main CPU and is also

used to upload firmware upgrades. Firmware upgrade is
performed using the . Load new firmware upgrades that may
