• Open the USB C waterproof cover (16);
• Insert the USB C end of the data cable (15) into the USB C socket (17)
on Dual;
• Connect the other end of the data cable to the power adapter (14), and
insert the adapter into a 100–240V power socket (13) for charging;
• When charging, a lightning charging icon appears on the battery
icon, flashing alternately with the current battery level, and the LED
indicator on the device is in red. When the LED indicator turns green, it
indicates that the charging is completed.
• During use, when displaying inside the icon, it indicates that the
power is higher than 20%, with sufficient power. If the battery icon turns
empty and flashes, it indicates a low battery level. Please charge the
battery in time to avoid the reduced service life of the device due to
battery over-discharging.

Safety Precautions
• When charging, please use the 5V2A power adapter compatible with
the device. Using any other type of power adapter may cause
irreversible damage to the battery or the adapter itself;
• If the device is not in use for a long time, the battery should be partially
charged, not fully charged or discharged.
• Do not charge the device immediately after it is moved to a warm
environment from a cold environment. Wait for 30 to 40 minutes for
preheating.
• Do not use the charger if it is modified or damaged;
• The device should be charged at a temperature of 0°C to +40°C.
Otherwise, the battery life will be significantly reduced.
• When charging, please do not leave the battery unattended;
• Do not connect the battery to the power supply for more than 24
hours after it is already fully charged;
• It is better not to connect the device to third-party devices that
consume more energy than the allowed value.
• The device is equipped with a short circuit protection system, but
conditions that may lead to a short circuit should be avoided.
• The recommended operating temperature for the device is from
-20°C to +50°C. Do not use the device beyond this temperature range,
or else, it may shorten the battery endurance.
• When the device is used under sub-zero temperature, the battery
capacity drops. This is normal and does not indicate a defect.
Dual supports external power supplies, such as the portable power
source for a mobile phone (5V).
• Connect an external power supply to the USB C port (12) of Dual;
• Then, the device automatically switches to the external power supply
and charges the internal battery pack at the same time;
• When the external power is turned off, the device will switch to the
battery pack for the power supply.
VII. External Power Supply

Notes:
• The maximum duration of a video recording file is 5 minutes. When the
duration is more than 5 minutes, the video will be automatically
recorded onto a new file;
• The number of files is fixed and limited by the memory space of the
device. Each device can store 1,650 photos and 850 videos. If it is
beyond this amount, the oldest photos or videos will be automatically
replaced. Please regularly transfer the material and photos to other
media to free up the space on the memory card.
• The interface icon information is not displayed on the captured video
or image.
Memory Access
When the device is powered on and connected to a computer, it will be
recognized by the computer as a flash memory card. Then, you can
access the memory of the device and copy images and videos.
• Connect the device to a computer through the USB cable;
• Power on the device;
• Double-click "My Computer" on the desktop of the computer, find the
device named "U disk" and double-click to open folders named
"VIDEO-CIF" and "PHOTO-CIF" to access photos and videos;
• Open the memory file, and there are different folders named after time
in the format of xx (day)xx (month) xxxx (year) in it;
• Select required files or folders to copy or delete.

In the observation mode, there are two modes of laser rangefinding:
single ranging and continuous ranging. The target distance is displayed
as 0000 m by default.
Single ranging mode: Align the center of the laser rangefinding reticle
with the target, press the Rangefinding button on the laser
rangefinding module, and the target range information is displayed on
the screen;
Continuous ranging mode: Align the center of the laser rangefinding
reticle with the target, press and hold (3s) the Laser Rangefinding
button to enable the continuous ranging mode, and the target distance
information is displayed on the screen and updated continuously, with a
1-second update time. Press the Rangefinding button to exit the
continuous ranging mode.
Note:
• After the device is connected to the computer, it prompts that only
part of the memory is available. This is because the storage algorithm
mechanism adopted by the device is different from that of the computer
and does not represent the actual memory occupation. Please check the
actual memory in Dual's device file management.
• After connecting the computer, do not use the computer's formatting
tool to format the device, because this operation will clear the program
inside the device!
