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.

2.5 Battery parts The LF10 primary battery configuration is the RRC2040, which is a small portable battery in an integrating housing. The RRC2040 battery option is presented in Section 2.5.1, while the second battery option called the Tracer battery – an external battery configuration – is described in Section 2.5.3. 2.5.
2.5.3 Tracer external battery parts If you purchase the LF10 supplied with the Tracer external battery, see the battery parts below: Bottom: The main battery of the LF10 1: Output connector for the battery cable 2: Charge gauge 3: Battery charger connector Top: 4: Battery cable connector Image 5: Tracer external battery parts 2.5.4 Tracer external battery charger The charger for the Tracer battery is an AC/DC converter with an output capable of charging lithium iron phosphate (LiFePO4) batteries.
3. GETTING STARTED The camera is powered by two sources of electricity: its own internal battery, and an external battery. The internal power supply is a lithium-based rechargeable battery installed inside the camera. To optimize internal power supply life during first operation, power on the LF10 camera for at least 45 minutes. When the internal battery needs to be recharged, the camera will prompt the following message: Please keep the camera on.
3.1.2 Charging the Tracer external battery Fully charging a discharged Tracer battery usually takes between 4 to 6 hours. Please note that the battery should be charged at ambient temperatures between 0°C and +40°C (32°F and 104°F). A new Tracer battery used under optimum environmental conditions yields up to 7 hours of usage. This depends, however, on multiple variables which may decrease usage time, including the cell temperatures, the load, and the age (i.e. charging cycles) of the battery.
3.2 Startup For startup, please see the sections below that provide instructions for starting up the camera using either the RRC2040 battery or Tracer battery. 3.2.1 Startup with the RRC2040 battery The RRC2040 battery set for the LF10 includes two batteries, a charger, a charger feeder cable, and a country-specific power supply cable. Please follow the instructions below and see Image 6 to start the camera using the battery, and if you need to attach the battery housing to the LF10 camera.
3.2.2 Startup with Tracer external battery 1. Attach the battery cable to the battery. There is only one way to attach the connector of the battery cable to the battery output connector. Push the connector downwards all the way. 2. Attach the connector to the LF10 by following the instructions in Image 8, with the orientation markings facing the same way: Image 9: Battery cable inserted in the LF10 camera. When the power is ON, the red Power LED of the camera is lit (Item 6 in Image 2).
3.3 Device setup wizard 3.3.1 Device registration The first time the LF10 is powered up, the device setup wizard will appear. The wizard will help you set up the settings needed for using the device, such as the WiFi settings (not supported in all regions), language, location, and time zone. This information can be changed later via the settings menu. Please see Section 4.7: Settings for more details. Create an account and register your device on the NL Cloud service.
4. USER INTERFACE You can control various LF10 functionalities and operations at the user interface. This section describes the functionalities and the settings available to the user when operating the camera, such as the heatmap, snapshots and video capturing, uploading and browsing through the snapshots, settings, real-time analysis, data transfer, and updates. 4.1 Heatmap The main view of the user interface shows the camera image with a heatmap overlay.
4.2 Taking a snapshot Press the Snapshot button to take a snapshot that contains the current camera image and heatmap. For analytics purposes, the snapshot includes a short video (4 seconds) and an audio clip of the strongest sound source. The video and audio clip are from the preceding 4 seconds before you press the Snapshot button. For this reason, you should keep the camera steady for a few seconds before taking a snapshot, in order to get a clear signal from the source of interest.
4.5 Zoom 4.7 Settings The LF10 is equipped with a 2x digital zoom that can be used for close-up snapshots. Press the Zoom Buttons to zoom in or zoom out. The zooming in option increases the directional resolution of the camera from 0.5° to 0.25°. 4.6 Quick settings Press the Quick Settings button to show the available quick settings. The possible settings are listed below. 4.6.1 Screen brightness The brightness of the display can be adjusted by pressing the Brightness button.
4.7.2 Time settings Remove all data The current time and date are shown under the time settings. Choose the correct time zone to see the correct local time. The time and date are automatically synchronized when connected to WiFi. All user data and settings can be removed from the device by pressing Remove all data. The snapshots and device registration will be removed. All users currently paired with this device will be unpaired from the device.
4.9 Cloud upload 4.10 USB export The LF10 will recognize the inserted flash drive and ask if you want to transfer snapshots to the USB device. If you press Yes, the transfer will begin. During the transfer, the progress will be displayed, and the transfer can be aborted by pressing the Stop button. Snapshots already transferred to the USB flash drive will remain on the flash drive and snapshots not transferred will remain on the LF10.
4.12 Remote update When connected to the Internet via WiFi, the LF10 will automatically download available software updates. If an update has been downloaded, it will be applied automatically the next time the LF10 is started. The current software version can be noted at the bottom of the screen when pressing the Settings button. 4.13 USB update If the remote update feature cannot be used, the LF10 can also be updated using a USB flash drive.
In challenging environments, the user can choose to modify the distance parameters manually. If the camera analytics recognize challenging environments, the display screen will make the user aware of the situation. The + and - buttons can be used to select the distance that you estimate to be the most accurate. 5.3 Specific settings Currency: Select the currency for the leak cost estimate from the available options.

6. USAGE TECHNIQUES See the sections below for recommendations on how to get the most out of your LF10. 6.1 General practice Use the wrist lanyard to ensure that you do not accidentally drop the LF10. Do not carry or lift the camera by the lanyard. Always carry it by its handle or body. Always keep the USB port covered. Water must not ingress the LF10, as this will damage the electronics inside. Do not touch the video camera lens or the conical microphone holes.
6.3 Reflections 6.4 Capturing distance The LF10 can sometimes show reflections of sound sources, most commonly in closed environments. In the event you suspect a reflection, move around the object you are inspecting and examine it with the camera from different directions. If the sound moves around or completely disappears, it is most likely a reflection or interference. If the source stays in one place when you move the camera, you have located an actual sound source.
7. NL CLOUD The NL Cloud is a free-of-charge online service that provides various analysis methods for sound imaging and signals, expanding the capabilities of the LF10. The NL Cloud stores the snapshots taken over a period of time, and reports can be generated. Connect to the NL Cloud by accessing it from any modern web browser (e.g. Google Chrome, Microsoft Edge, or Mozilla Firefox) at the following address: view.nlacoustics.
9. MAINTENANCE - NOTE: 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. The intended usage conditions and instructions are specified in this User Manual. Please read and follow the instructions carefully in order to maintain your LF10 in optimum condition and prevent damage to the device and accessories.
