Safety Advice
 Before using the torch, ensure that you read and understand the safety advice leaflet so that the torch is
always operated correctly.
 Never point the light beam at your or other persons eyes. Doing so could damage the retina.
 Keep the torch away from children.
 Never attempt to take the torch apart unless it is specifically directed in the operating instructions. Doing so
can result in severe in uries and electric shocks. Servicing of internal components, servicing or repairs have
to be carried out by qualified persons, authorized by the manufacturer.
 If smoke or steam appears, switch off the mains or battery supply immediately. Disconnect the torch head
from the battery and remove the charger from the socket.
 Do not touch the charger’s power cable with wet hands as there is danger of an electric shock or short
circuit. To disconnect, depress the catch on the connector whilst withdrawing it from the charging adapter
plug. Do not disconnect it by pulling on the cable.
 To prevent overheating, damage, fires, electric shocks or other dangers only use the charger and
attachments supplied.
 Keep the torch and battery pack away from open fires or sources of heat as it could lead to overheating,
fires, electric shocks and explosions and cause severe in ury.
 Never attempt to change or take apart the battery pack. To do so could lead to in ury by explosion.
 Do not drop the batteries or battery packs and protect them from impact. Damage could result in leakage of
the battery chemicals and result in in uries.
 Clean with water all areas of the body (especially mouth and eyes) or clothing that come in contact with
battery chemicals.
 Never short across the battery contacts with metal ob ects (e.g. key rings, screwdrivers etc) as this could
result in overheating and to burns and other in uries.
 After charging disconnect the charger from the battery pack and the mains socket to avoid fires or other
damage.
 The charger supplied with the torch has been developed for use exclusively with the torch and battery pack.
Do not use it with other products or batteries as this could result in fires or damage.
 Use and store the torch, battery pack and charger away from exposure from heavy solar radiation or high
temperature (e.g. the dashboard or the boot of a car etc.). Heavy solar radiation and heat can lead to
leakage, overheating or explosion of the batteries which can result in fire other damage.
 While charging the battery pack keep it in a well ventilated area.
 Charge the battery pack at room temperature.
 If the batteries become too warm, cease charging immediately. Normal temperature is slightly higher than
“hand-hot“ ( +/- 50 degree )
 Let the batteries cool down after charging.
 Use the torch, battery pack and accessories only when diving. Using the products or other component parts
for other purposes is not allowed.

General Care and Usage Instructions
 The O-rings (sealing rings) should only be removed if they require replacing.
 Lubricate the O-rings occasionally with a smear of silicone grease. Please do not apply
to much grease. Do not use silicone spray !
 Regularly inspect the O-rings for damage or contamination, and change them if
necessary. We recommend that you carry spare O-rings.
 The torches can be operated out of water for a short time, however they will become
very hot very quickly so do not leave unattended. Only operate until the torch head
becomes warm.
 After use rinse the torch thoroughly with fresh water whilst still attached to the umbilical
and battery pack. Never use any other cleaning agents.
 Do not shine the torch into your eyes or the eyes of others as severe damage to the
retina could result.

otes on the use of mechanical dimming
The mechanical dimming does not work as a electronics, it works with a spring. Switch on the
dimming as follows:
 Screw in the battery tube short completely = light power 100 %
 Screw the battery tube short few millimeters in the direction of „OFF“ = light power is
dimmed
 Screw battery tube short further in the direction „OFF“ = the light is off
As long as the battery tube is turned, the light is flickering. This is normal and owed to the
mechanics.
If the battery tube is not turned, the light no longer flickers.
If the light flickers even in the position, when the torch is completely on, clean first the silver border
of the battery tube short. Over time of using the torch deposits (grease rests etc.) can place here,
which must be removed. Please also note that the contacts on the LED module are kept clean.
Which one LED module is used ?
Usually there is no optical recognition of which LED module is installed.
Thats why you should read the following hints :
The LED module is marked on the back of the LED board.
Unscrew the short battery tube or the battery tube short compact or the umbilical from the lamp
head.
Then look into the open lamp head from behind.
There are 4 coloured dots, always starting with white.
So the first white dot plus 3 additional coloured dots.
This results in a colour code.
The colour code you find under www.TillyTec.de in the downloadcenter under :
INFORMATION
User manuals / possible components
Possible – components view / download
Find the appropriate colour code from the table. You will see here the name of the LED module, as
well as the possible configurations with batteries and rechargeable batteries, as well as the
corresponding burning times.

otes for using of charger
 The hints of the operating instructions of the manufacturer are to be observed.
 The charger has several LED lamps that indicate the progress of the battery charge.
 The charger can connected to the battery verytime. You do not have to discharge
the battery !
IMPORTA T: Use chargers only indoor or in dry rooms. The voltage values and
settings must be respected.
Burn time and light power
 The burn time and the light power of the torch depends on
- the used LED modul
- the used type of battery or accumulator.
TIP : When the LED module of the MAXI uni is not bright enough
we will send a stronger LED module for trial for free.
 More information about burning time and light power you will find on www.TillyTec.de –
on register „information“.
Operation and Handling / Changing the LED moduls
 To turn your torch on and off, rotate the torch head. A half rotation is sufficient to
engage the contacts. Further rotation when switching off is not a problem as the
system is protected with 3 O-rings, however it should be stopped when the first O-ring
is visible.
 How to change the LED modul you can see on the website www.TillyTec.de or at the
TillyTec youtube channal. Please have a look !
IMPORTA T : Tighten the space holder very strong by hand. Otherwise the cooling of
the LED module is not enough. So the LED module will be destroyed immediately !
 The space holder is hand tightened to press the LED module against the glass. This is
necessary so that the LED module can be cooled well. Without cooling the LED module
is destroyed ! The space holder should be clean and free of grease on the flat side,
where the LED module lies cloosly for cooling (cooling paste may be used).If you use a
version where the LED module is screw on the pace holder with socket screws, please
screw the LED – module tightly tot he space holder.
Videos, which explain the change of the LED modules, can be found on the homepage of
TillyTec (www.TillyTec.de) or on our own Youtube channel. PLEASE LOOK THEESE
VIDEOS !!!

 After the space holder is screwed hand tight, the battery tube is screwed together with
the battery in the lamp head to see if the torch is working.
Screw the battery tube only
slightly ! not strong ! Screw it only until the torch is on. Repeat the turning on and off
several times and watch the LED module . But never look directly into it ! When
switching on and off the LED module should not or only very little rotate (only a few
millimeters). If the LED module rotates to much the space holder is too loose.
 Please check the space holder every 15 to 20 dives and if it is nessesary please
screw it a little bit stronger !
IMPORTA T !
To ensure the tightness of the torch please grease the parts as following is
shown regulary:
 The three O-rings on the lamp head ( 1 ) are only visible, when the torch is opened to
change the LED Module. In this case please grease always these O-rings !
 The tread of the space holder ( 2 ) inside please grease all 10 - 20 dives . This do only
in the range of 10 - 15 mm from the beginning of the hexagon . The tread of the spacer
( 2 ) outside always grease when the LED module is changed .
 The three O-rings in the protective ring (3) are only visible when the space holder (2) is
completed removed. When the LED Module will changed always grease the three O-
rings.
 The three O-rings on the battery tube ( 4 ) are always visible, when the battery tube is
unscrewed This must be greased at least every 10-20 dives regularly or whenever the
lamp is not used for a long time ( approximately 3 months ) .
GREASE MEA S : It is to see a glossy film - it is not swimming in grease !

screw and moving the Goodman's
plate.
Here it can also be rotated
completely for transport and
protection of the lamp head.
The Goodman can also be
ad usted in size by
loosening and sliding the
a
llen screw
The hose supplied can be
mounted around the lamp
head/battery tube of the
Maxi uni. This means that
the Goodman's clamp sits
more firmly at the lamp
head / battery tube and the
lamp head / battery tube
does not spin when the
lamp is switched on.

The Goodman hard heavy
duty offers the possibility to
use different combinations of
the Maxi uni and Mini uni at
the same time. The battery
tube short compact can also
be used instead of the maxi
uni.
Maxi uni / Mini uni
Goodman hard heavy duty
-
adapter
The following combinations are possible:
- 1 x Maxi uni / battery tube short compact
- 1 x Maxi uni / battery tube short compact + 1 x Mini uni
- 1 x Mini uni
- 2 x Mini uni
- 3 x Mini uni
For use the Mini uni S3, the red adapter ring must ALWAYS be
installed. Before mounting on the Goodman hard heavy duty, we
recommend first mounting the adapter ring on the Mini uni S3.

IMPORTA T !!!
The clamp of the Goodman hard heavy duty MUST be flush with the
battery tube short compact.
If the clamp is not mounted in this way, the battery tube short compact
will be LEAKI G !!!!
The same applies to your own attachments that are mounted around the
battery tube short compact (for example your own clamps, stainless steel
clamps an so on)
Fastenings in the rear area of the battery tube are also not
permitted and lead to leaks!

Important notes for the use of the battery cells
 LiCoMn (Lithium Cobalt Manganese) or LiCoNi (Lithium Cobalt Nickel) battery cells
do not have any self-discharge.
 Full charged batteries must be recharged after 12 months of storage.
 For a charge after a storage period, the charger can be connected to the battery
cells without prior discharge. The charger calculates the remaining capacity and
charges the battery cells.
 After each use the battery should be charged. It does not matter how long the torch
was used.
 We recommend to remove approx. 30-80 % of the capacity of the battery to
improve the lifespan.
 Complete discharges until the end of battery capacity reduce the lifespan of
battery.
 The lifespan of battery depends on the following points :
- how many times is between the using of battery cells and the recharging ?
Battery cells should recharged after using as soon as possible.
- how much rest capacity is in the battery cell after the using ? The lifespan of
the cell is much higer if the battery cell is only 30 % of capacity unloaded
than 80 % of capacity.
- how often you use the battery cells ? For daily use of the battery cells
the lifetime is many times better than a few uses a year.
 Generally the battery life depends very much on the handling of the user.
 The battery life is between 7 days and 7 years !
 Are the battery cells daily used than are 500 to 1000 charging cycles possible.
 Are the battery cells using only some times in the year than the the end of life can
be reached after very few charging cycles.
 In order to guarantee the safety in the TillyTec dive light, we only recommend
the use of LiCoMn or LiCo i accumulators. The use of other Li-Ion batteries,
with a different chemistry, is at your own risk. Li-ion battery cells can
explode.

the torch. After the using of the torch remove the batteries as soon as possible, charge the
batteries immediately and store the batteries fully.
Die Akkus dürfen ICHT im Akkuhalter verbleiben oder dort gelagert werden
EVER left in the batteries in the battery holder or store the batteries in the battery
holder !
That means :
 Insert batteries before the dive
 Immediately remove and recharge the batteries after the dive
 Store the batteries necessarily in the battery box
To improve the lifetime of the batteries, please note the following aspects :
 all used batteries are from the same manufacturer
 all used batteries have the same capacity
 all used batteries have the same numbers of charge cycles
 all used batteries have the same age
 the battery holder should always be equipped with the number of batteries for which
it is intended (here 3

Advice on using LED modules
 There are many different so called „P60 Drop in“ LED modules, not only the original
from TillyTec.
 To install and remove the LED modules you can see videos on www.TillyTec.de or at the
TillyTec youtube channel!
otes for using of charger
 The hints of the operating instructions of the manufacturer are to be observed.
 The charger has several LED lamps that indicate the progress of the battery charge.
 The charger can connected to the battery verytime. You do not have to discharge
the battery !
IMPORTA T: Use chargers only indoor or in dry rooms. The voltage values and
settings must be respected.
Burn time and light power
 The burn time and the light power of the torch depends on
- the used LED module
- the used type of battery or rechargeable battery.
TIPP : Various LED modules can be purchased on the internet market, starts from
about 6 Euro. Search for "P60 drop in" modules !
Operation and Handling / Changing the LED moduls
 Unscrew the rear part of the Mini uni (has a spring).
 Install the 18650 / 21700 rechargeable battery or non rechargable batteries AAA with the
positive pole pointing upwards towards the head.
 Unscrew the rear part (with spring).
 Switching on and off is done by turning the rear part of the battery tube ( OT AT THE
FRO T OF THE FRO T ATTACHME T !). Half a turn is enough to start the process. If
you turn several times when switching off does no harm, because the seal is made with
three O-rings. The turning should be stopped when the last O-ring is visible.
 The LED modules are changed according to the instructions on www.TillyTec.de or at the
TillyTec youtube channel. Please take a look necessarily !
