Purpose

The 

Tecline

TECLIGHT

 diving light is intended for under water use.

You can select one of 3 light modes:

1. Communication Mode

 (1300 lm, beam angle: 6°)

2. Combined Mode

 (Communi Video) (3900 lm, beam 

angle: 6° + 120°)

3. Video Mode

 (2600 lm, beam angle: 120°)

When using the lamp on the surface - use only Communication 

Mode. It will prevent the LEDs from overheating and save energy.

To avoid overheating and damage to the lamp on the surface, use 

the video mode only when checking the lamp (max. 1 minute).

Before using the lamp, check its sealing, i.e. check if all parts 

sealed with o-rings are properly tightened. Make sure the con

-

necting cable is properly tightened. O-rings must not be dirty. 

Any damage, e.g. scratches, cracks, cuts may cause leakage, and 

consequently damage the lamp.

Turning on / off / changing operating modes:

Use the main switch button, located on the back of the lamp head, 

to turn it on.

The same button is also used to change light modes.

To activate the lamp, connect the battery to the head and then 

briefly press the main switch (located on the lamp head).

The lamp is turned off by holding the switch for more than 3 

seconds.

Changing the operating mode:

Press the main switch once = Communication Mode

Press the main switch again = Combined Mode (Communication 

+ Video)

Press the main switch again = Video Mode

This sequence will be repeated when you press the main switch 

again.

Turning off the lamp:

Keep the main switch pressed until the lamp is turned off.

Burn time will be the longest in the Communication Mode. It will 

be reduced in Video Mode and in Combined Mode (Communication 

+ Video).

In Video Mode, the battery will discharge faster.

The 

Tecline

TECLIGHT

 lamp is equipped with a discharge control 

system. It will issue a warning to protect the lamp from excessive 

battery discharge. This will allow you to safely and optimally 

manage the lamp use and to ensure optimal burn time.

Low battery warning system

The lamp will signal that the battery is discharged to a level of 

10% by switching several times between Communication / Video 

Mode. After that, the lamp will switch to Communication Mode

with reduced power, so you will save energy to safely end the 

dive.

In this situation, the battery needs charging. Continued use of the 

flashlight in the Safe Mode is possible, but remember that the 

lamp will only work for about 60 minutes.

Mounting

Tecline

TECLIGHT

 battery canister can be mounted on the harness. 

To do so, we recommend to lead the waist belt through the 

canister loop and secure it with an additional buckle. 

In a sidemount configuration mounting system depends on the 

buoyancy device and the available attachment points.

In order to protect the cable from sharp bends, make sure you use 

the lamp with an optional 90° angle connector when diving in the 

sidemount configuration. 

Hold the lamp head by using the integrated “goodman” handle, 

so the lamp head rests on the back of your left hand. You will be 

able to use both hands during your dive. Be sure to adjust the 

goodman handle to your hand to optimize the grip.

The lamp handle is equipped with a “DPV Ring”. It allows you 

to temporarily hold the lamp head with your right thumb while 

diving with your diving scooter. In this way you can easily mani-

pulate your equipment (e.g. check your SPG with the left hand ).

The small hole on the right side of the goodman handle allows 

you to attach a fixed bolt snap. It serves to stow the lamp when 

it is turned off.

The loop on the cable, just behind the lamp’s head allows to stow 

the lamp temporarily (using a double-ender), when the lamp is 

turned on.

Transport

Tecline

 TECLIGHT

 lamp is entirely prepared for air transport 

(together with the battery). The lamp should be carried in hand 

luggage with the head disconnected from the battery. The 

flashlight must be protected from bumps and shocks. 

Before travelling by air, please read the carrier’s instructions for 

the Li-Ion battery transport.

The carriage of battery-powered electrical equipment is regulated 

by specific directives. Please read the local regulations before
