NL Acoustics LF10 - Introduction; User Safety

2. INTRODUCTION
Thank you for choosing the LF10 camera! The LF10 is a
standalone system for acoustic image measurement and
signal analysis. The 124 microphones of the LF10 are used
to form a precise acoustic image of a specific location.
This acoustic image is superimposed in real-time over
adigital camera image. The location of the sound source
is shown on the camera screen. Sound sources of interest
are separated from background noise. The details of each
acoustic image can be saved onto the NL Cloud for further
viewing and AI-backed analysis.
The LF10 camera is much more sensitive and accurate
than the human ear. The camera can locate sound sources
that are inaudible to the human ear as well as sound
sources that humans cannot reliably locate. The LF10 has
a frequency range that extends to ultrasonic frequencies,
which is a huge advantage since many relevant
problems and phenomena can be precisely located
using ultrasound. One of the core benefits of using the
LF10 camera comes from its ability to hear and analyze
ultrasonic frequencies. Most maintenance and operational
problems can be identified and accurately located at
these frequencies.
2.1 User safety
Only genuine parts from NL Acoustics should be used
with the LF10 camera. Under no circumstances should
users make use of third-party parts.
Do not try to repair or open the enclosure of the LF10
camera or the batteries. Do not use any damaged device,
battery, or cables.
Protect the device and accessories from dirt, dust,
impacts, and liquids. Also protect the camera lens,
themicrophone array, and the USB port from any kind
offoreign objects, dust or liquids.
Charge the battery only when it is disconnected from the
LF10 camera.
The LF10 camera is not intended to be used while the
battery is charging. Charge the battery only when it is
disconnected.
Charge the battery at ambient temperatures between 0°C
and +40°C (32°F and 104°F).
Do not leave the battery unattended during charging.
Do not expose the battery to flame or excessive heat.
Hold the LF10 firmly by the handle and fasten the safety
lanyard to your wrist.
Do not touch the heat sinks when the device is on,
as the heat sinks become hot when the camera is on.
Long-term contact may cause burns. For this reason, it is
recommended that any USB flash drives be connected
directly aer starting the device.
Consult with your safety officer in your facility or working
environment about using the LF10 and, if powering the
device by external battery, about using the carrier bag
with shoulder strap. In you use the shoulder strap with
your LF10, particular care should be taken to prevent
getting entangled in your working environment.
Use only the USB flash drives supplied with the LF10
camera. Using third-party mass storage drives may lead
todata loss or corruption.
