BATTERY AND SAFETY

Finder II series is supplied with a quickly removable 18650 Liion battery pack, which enabled the device to be used for up to 5.5h. The battery should be ully charged before ﬁrst use.
Battery Pack Installation

Turn up the puller (15) on the battery pack (8), and align the orange line (D) on the battery pack (8) with the triangle symbol (C) on the battery slot (16) and push the battery pack (8) into the battery slot (16).
When the battery pack is completely inserted into the battery slot, turn the puller (15) clockwise to lock the battery pack.
Close the puller (15), and the battery pack is completely installed.
Finder II series can only be powered by this battery pack. If other battery packs are used, it may cause irreparable loss, damage to the device, and can even possibly cause ﬁre.

Method 1: Charging with Type-C Port

Align the orange vertical line on the battery pack with the white triangle symbol next to the battery compartment on the Finder II, and install the battery pack into the battery compartment of the product. For details, see Battery Pack Installation.
Connect the Type C end of the data cable (18) to the Type C port (13) of the product.
Connect the other end of the data cable (18) to the power adapter (19) that comes with the product, or connect to another USB power socket with a rated output voltage not exceeding 5V.
Plug the adapter (19) into a 100-240V power socket (20) for charging.
when charging, the LED indicator will change to red. LED indicator displaying the current status of the device

Method 2: Charging with Battery Charger

Align the positioning block (A) of the battery pack (8) with the groove (B) of the battery charger (15), and insert the battery pack (8) into the battery charger (15).
Connect the plug of the USB Type-C cable (18) to the USB connector of the power adapter (19). Plug the power adapter (19) into a socket 100-240V (20) (110V for US).
Connect the other end of the USB cable (18) to the Type-C port (16) of the battery charger (15).
After ﬁnishing the above steps, the LED indicator (17) on the battery charger (15) will display the battery charge state.
After the battery is fully charged, remove the battery pack from the battery charger.

Battery charge status (see table).

LED Indicator	Battery charge status
Battery level is from 1% to 25%.

Battery level is from 25% to 50%.
Battery level is from 50% to 75%.
Battery level is from 75% to 99%.
Battery is fully charged.

Note: Two batteries can be charged at the same time: the second slot is designed for it.
Safety Measures

Use this battery charger to charge the battery pack only. Otherwise it will cause irreparable damage to the battery pack or charger and even may cause ﬁre.
Before a long storage time, the battery pack should be partially charged, not fully charged or discharged.
Do not charge the battery immediately after you bring it from the cold to the warm. Wait 30 to 40 minutes for it to warm up.
Do not use the charger if it is modiﬁed or damaged.
The device should be charged at a temperature of 0°C ~ +45°C. Otherwise the battery life will be signiﬁcantly reduced.
When charging, please don’t leave the battery unattended.
Do not expose the battery to high temperature or open ﬂame.
Do not immerse the battery in water.
The battery pack has short circuit protection. But situations that may lead to short circuits should be avoided.
Do not charge the battery for more than 24 hours after it is already fully charged.
It is not recommended to connect third-party devices that consume more power than allowed.
Do not disassemble or modify the battery pack without professional instructions. Do not knock or drop the battery pack.
The recommended operating temperature for the device is 20°C ~ +50°C. Do not use the device beyond this temperature range, which may shorten the battery life.
When the device is used under sub-zero temperature, the battery capacity drops, which is normal and does not indicate a defect.
Please keep the battery pack out of the reach of children.

EXTERNAL POWER SUPPLY
Finder II series supports external power supply, such as the portable power source (5V).

Connect the external power supply to the Type-C port (13) of the device.
The device will automatically switch to the external power supply and charge the battery pack (8) at the same time.
At this time, the battery icon on the display will become to the charging icon and the power indicator will turn red, and then turn green after the battery is fully charged.
If an external power supply is connected, but no battery pack is installed, the battery icon will become a USB icon and the power indicator will turn green.
When the external power supply is disconnected, Finder II series will automatically switch to the battery pack power supply and will not shut down.

The image is too dark.| Low brightness level set.| Adjust display brightness.
Colored lines appeared on display or the
image has disappeared.| The device was exposed to static electricity during operation.| After exposure to static electricity, the device may either
reboot automatically or require turning off and on again.
Poor image quality/ reduced detection
distance| These problems may occur during observation in difﬁcult weather conditions(snow, rain, fog, etc. ).
Smartphone or tablet cannot be
connected to the device| The device password has been changed.| Delete the network and reconnect using the device
password
The device is in an area with a large number of Wi-Fi networks that may cause interference.| To ensure stable Wi-Fi operation, relocate the device
to an area with fewer Wi-Fi networks, or into an
area with none.
Malfunction| Possible reason| Correction
---|---|---
Wi-Fi signal non existent or interrupted| Possible reason The device is outside he area of Wi-Fi coverage. There are obstacles between the evice and the receiver (e.g. concrete alls.)| Relocate the device into direct line of sight f the Wi-Fi signal.
When used in low-temperature conditions, the image quality of the surroundings is worse than in positive temperature conditions.| In positive temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high-temperature contrast. Accordingly, the image quality roduced by the device will be higher. In low-temperature conditions, objects being observed (background) do, as a ule, cool down to roughly the same temperature because of which temperature contrast is substantially reduced nd he image quality (detail) ispoorer. This is a feature of thermal imaging evices.
