1.2 Safety Precautions
CAUTION
•Please read and follow all safety precautions to ensure your own safety and to protect
your device from potential damage. The warranty does not cover damage caused by
negligence or misuse, for which we shall not be held liable.
•Keep this user manual in a safe place where anyone can access it.
■This device has been manufactured and certified for industrial use only, not for individual
purposes.
■Do not poke eyes, ears or other body parts with the device, nor put it in your mouth.
Otherwise, it can cause severe injuries or pose a choking hazard.
■Wear appropriate clothing to avoid skin contact with your neck camera, system body and
external battery. Make sure the system body or external battery is kept in the pouch when in
use. Otherwise, it can pose a risk of low-temperature burns if exposed to heat or used by
someone with poor blood circulation or sensory impairments.
■Do not let the device in use or AC adapter come into contact with the skin. Otherwise, it can
cause low-temperature burns from the heat produced by prolonged use of the device.
■If the AC adapter or any optional accessory becomes hot, discontinue use immediately.
Otherwise, it can cause low-temperature burns or product damage.
■Do not use the device in areas affected by heavy smoke or steam. Otherwise, it can lead to
product failure or damage.
■Always use genuine accessories, batteries and cradles specified or provided by LINKFLOW.
Unauthorized components may shorten the product life or cause overheating, a fire or an
explosion, possibly resulting in serious injuries and product damage.
■We do not take any responsibility for issues caused by improper operation during an update.
They may require paid repair services.
■Always keep a backup of your important data. We will not be held liable for any data loss.
■Make sure the system body is turned off when installing/removing a neck camera or a
memory card.
■Memory cards are consumables and need to be replaced periodically (after 3 months is
recommended). Check your device specifications for supported memory card types before
replacing the memory card. (Up to 64GB, Class 10 memory cards supported)
■In wireless networks, security settings are particularly important. Please note, however, we will
not be liable for any security issues resulting from your wireless network environment or
security settings.
■Anyone who uses this device must comply with the Personal Data Protection Laws and
portrait rights. Unauthorized surveillance, secret recording or invasion of privacy is prohibited
and may lead to criminal prosecution.

■It is recommended that the cradle be stuck to a large, flat fixed glass surface.
■The AC adapter supplied with the device is only for use with NEXX_ONE cradles. Do not use
any charger other than this adapter. Using any other charger can result in an explosion
damaging your device.
■Do not connect the negative and positive of the cradle directly. Doing so can cause a fire or
serious injury.
■Keep the cradle connection area free of any substances, including moisture, dust, metal filings
and pencil leads. Do not poke with sharp objects or apply excessive weight or pressure. This
can cause corrosion on the power terminals or a short circuit, possibly resulting in a fire or
explosion.
■Do not bend, pull, heat or place heavy objects on the power cord. A damaged power cord
may cause an electric shock or fire.
■Do not use power sources other than AC 100-240V. They may cause an electric shock or fire.
■Only use the AC power cord supplied with the device.
■Unplug the cradle when not in use.
■Do not pull on the cord when removing the plug from the outlet. It may lead to an electric
shock or fire. Unplug from the power socket by grasping the AC plug body.
■Do not cover the cradle with clothing, cushions, etc. The cradle can overheat, possibly
distorting the device or causing a fire.
■Do not use a frayed or damaged cord, broken plug or loose outlet. Poor connections can
pose a risk of electric shock, fire or injury, and the battery may not be charged.
■Do not place your device near heat sources. It may cause a fire or damage to the device.
■Do not attempt to modify or take apart the device. It can pose a risk of electric shock or fire.
■Avoid causing damage to the lens. The lens elements are made of glass and are susceptible to
breakage or damage.
■For safety reasons, the battery may stop charging if overheated or charged at a high
temperature.
1.2.1 RF Safety Guidelines
This device uses the 2.4GHz/5GHz frequency bands. A radio communication license is not
required to use this device, but it is recommended that you read and follow the safety guidelines
below.
■Do not use your device in an automobile, in a hospital or near medical equipment that may
be affected by radio frequency radiation. If you have a medical device for your own personal
use, please contact the manufacturer to make sure the device is not affected by high RF
intensities.

9
■Use of electronic devices on aircraft may interfere with aircraft navigation systems. Follow the
instructions of crew and on-board procedures when on board. Remove the wireless dongle
even if allowed to use electronic devices in flight.
■Automotive electronic systems may not operate properly while being exposed to high RF
energy. Contact the manufacturer to make sure the vehicle is safe from high RF intensities.
■Do not use your device in close proximity to medical devices such as a cardiac pacemaker.
The RF energy from your device can interfere with some medical devices such as a cardiac
pacemaker.
■Do not use near a microwave. RF interference may occur when the device is used near a
microwave, causing a breakdown or slowdown in communicating.
■A wall or partition, made with any metal, steel or concrete, between this device and a wireless
device may cause a breakdown or slowdown in communicating. If such a situation occurs,
please change the installation location of this product or wireless device or remove the
partition.
■Do not use in the vicinity of on-premise or certain low-power radio stations for mobile
identification. On-premise stations for mobile identification that are used by factory
production lines, along with industrial, scientific and medical devices, operate on the
frequency band used by this device.
■Before using this device, make sure that no on-premise, low-power or amateur radio station
operates nearby.
■If your device interferes with any such station, discontinue using it immediately and contact
the seller or LINKFLOW to enquire about measures to avoid interference, such as by installing
a partition.
■Please contact the seller or LINKFLOW regarding any other product interfering with an on-
premise, low-power or amateur radio station.
1.2.2 Safety Precautions for Handling Batteries
CAUTION
•These safety precautions apply to the system body and external battery. Neglecting
these instructions may result in serious damage or other dangerous situations.
■Please stop charging or using the device immediately if:
-there is smoke, a leak or odor coming from the battery;
-the system body or external battery expands, distorts or discolors;
-the system body or external battery is too hot.
■If the system body, external battery or cradle malfunctions, immediately remove and place the
device on a concrete slab away from buildings and combustible materials. Do not reuse or

10
recycle the battery. Dispose of it immediately in accordance with applicable waste regulations.
■Keep the battery and cradle out of the reach of children. Call an ambulance, if you suspect a
battery has been swallowed.
■Do not use batteries other than those designated. Otherwise, there is a risk of battery
explosion, leakage, damage or fire.
■Only use the specified cradle. Using an unspecified charger can result in an explosion or
breakdown.
■Do not touch the device, power cord, plug or outlet with wet hands or body. This increases
the risk of electric shock.
■Never disassemble, cause a short circuit or expose the battery pack to fire. This poses a risk of
battery explosion, leakage or fire.
■If you intend not to use the camera for a long time, please remove the external battery before
storing.
■Do not shock or shake the battery. Applying excessive force can lead to a battery explosion,
leakage or fire.
■Do not attempt to modify or take apart the battery. This poses a risk of electric shock or fire.
■Using the device in a cold environment may shorten the battery life even though it’s fully
charged.
■Comply with your local waste regulations when disposing of batteries.
■Do not place or dispose of batteries in a general waste bin.
