1. Description
LNK-DT1 diving torch which is controlled by three separated magnetic switch is a professional diving
equipment designed for deep-sea operators and divers. It adopts double-layer LED layout having
different functions with adjustable luminous intensity : strong light in the center used for searchlight over
long distance underwater; weak light in all round used for the photographing light at short range
underwater; SOS signals used for the emergency light underwater. Inbuilt multi rechargeable lithium
batteries, not only can guarantee the need for multiple diving over a long period of time, but also can be
used as a portable power source to charge other devices via standard external USB interface.
The product which is water-proof to a depth of 50m can be widely used in deep-sea fishing,
collection, photography, exploration , archaeological and other diving activities based on the functions of
underwater lighting, photography, SOS signal light and mobile charging.
2. Product Structure
LNK-DT1 diving torch adopts an integrated design, make main body sealing, and reserve underwater
camera installation hole. The base is provided with a charging socket ” IN”, a portable source socket ”
OUT”, a battery power indicating LED and a system reset button “ RESET”. The bottom cover is fitted to
the torch body through screw thread. Each product is equipped with a standard 5V2A charger and one
Micro-USB charging line. The configuration of the product is shown in figure1~2:

4. Installation and Operation Guide
4.1 Installation
（1）There is no need to install the diving torch on other devices because itself is a
stand-alone handheld device. Users can choose suitable bandage to fix it on the arm
according to diving needs.
（2）The LNK-DT1 diving torch has provided the installation position for the underwater
camera. Users can select the appropriate camera equipment according to needs and
install it with M5 screws and matching nuts.
4.2 Operation
（1）In order to guarantee transportation safety, the LNK-DT1 diving torch usually keeps
a low battery state when shipped out from factory. After receiving the product, users
shall charge the battery by opening the bottom cover of the torch, inserting the
charger into the IN interface, and then connect external power until the four red LED
lights are all in normal bright state which indicates that the battery is full, and stop
charging.
（2）Three manual magnetic control switches are arranged on the main body of the torch
to realize the functions of spotlight, floodlight and SOS. Users only need to drive the
magnetic control switch according to the corresponding mark to obtain the
corresponding function, and the switch will be automatically reset. Spotlight and
floodlight both are configured with three grades from weak to strong. Users can use
or mix using the strong / weak spotlight and strong / weak floodlight according to
the underwater environment.
The functions are as shown in Figure 3 below
Figure 3
（3）Users can check the red LED power indication state on the base through the
transparent window of the bottom cover before or after use. If 4 LED lights are
constant bright ,it represents full power. When there is only one constant bright, it
cannot be judged whether the power is nearly out or not. At this situation the

function may be abnormal, and it cannot be used for diving. In order to avoid
accidents, it is necessary to charge the battery before using it.
（4）The torch can be used as mobile power source to charge the mobile phone, camera
or other small electronic devices for a short time in the condition of sufficient
electricity. The charging time and efficiency will be different based on the different
power of equipment.
（5）If the product function is invalid for self-protection caused by short time operation
outside of water or frequent use of button, users can touch the RESET button on the
base with a small thimble, and then the torch will start again normally.
（6）When the bottom cover is opened for charging, reverse charging and resetting, users
need to install the cover back to the torch body and keep it tight to ensure the
product is waterproof.
5. Protection Requirements
（1）LNK-DT1 diving torch should be stored in a clean, no polluting and no hard object
contacting environment.
（2）The material of the torch lampshade is glass and the main body is aluminum alloy. In
order to prevent damage or surface abrasion caused by falls or crash, the torch
should be put back to original package after each use.
（3）Prohibit force opening the sealed structure parts of the torch to operate except the
bottom which can be separated.
（4）In the state of storage, charge and discharge should be carried out at intervals of 3
months to maintain the activity of the battery.
6. Service Life
LNK-DT1 diving torch adopts rechargeable lithium battery. Based on the charge and
discharge characteristics of lithium battery , the battery capacity is reduced by about 20% after
charging 500 times, and reduced by about 50% after charging 1000 times. Therefore, the
working time will gradually decline even the torch is full of electricity with the increase of
charging times. Users should pay attention to the actual performance, and recommend
replacing a new one when charging more than 1000 times.
