Warning: the lamp is waterproof only when it is connected directly to the battery box or when using our IP69 connector. This one
must be connected male and female locked correctly. Outside these two contexts, we do not guarantee the watertightness of the
lamp. Before connecting your IP69 connector always ensure the connection system in clean, check the presence and the wear status
of the two O-rings seals and if needed replace or clean them. O-Rings can be lubricated using an hydrophobic silicon based lubricant
for facilitating connector sealing and enhance the O-rings lifetime.

Temperature of use:
Minimal service temperature: -40°C (-40°F) / Maximal service temperature: +50°C (+122°F). Our lamp is equipped with a temperature
control which will reduce automatically the light power to avoid overheating which can be expected in hot environment if the lamp is
used for a long time on the high level modes.
OPERATING INSTRUCTIONS
Battery insertion, charge and good practices to enhance their lifetime:
At delivery, the Ansmann batteries we provide are charged at approximately 20%of their capacity, please ensure to fully charge them
before first use especially if you plan to need lighting for a consequent time.
Our batteries are Lithium-ion batteries. They cannot suffer from any significant impact and especially not be thrown in fire.
At end of their life batteries should be collected according to local legislation regarding batteries recycling or storage.
For charging your batteries you can connect them directly to our Ansmann chargers, for lamps equipped with our IP69 or IP65
connectors, the connector can be directly connected to the charger. In all cases, even if all our connectors are indexed (see picture
below), be careful to respect polarity while connecting the components together.
Approximate time needed to charge your batteries:
Battery type 11.1V / 2.6Ah: 3h45
Battery type 11.1V / 5.2Ah: 7h30
During charging an orange LED indicates that the charge is in progress
Once the orange LED is not lighten anymore that means the battery is fully charged. Polarity index

To enhance your batteries lifetime never let them discharge totally and do not store them for a long time if they are close of total
discharge.
If you plan to do not use your lamp for more than one week disconnect the batteries from the lamp. A good practice for storing
batteries while not using them is to keep them disconnected in a cool and dry place at approximately 50% of their charge capacity.
Our battery boxes are provided with two types of closing screws, one of them is filled with plastic head allowing you to opening the
box by hands. For caving and some underwater activities (such as cave diving) the screws with plastic heads shall not be used as
they could induce an opening of the battery box in case of shocks or contact with the rocks in narrow passages. For such activities
always use the naked stainless steel screws provided (or equivalent) and remind to bring an adapted tool with you if you need to
replace the battery.
Please ensure before closing the battery box that the connecting cables are properly positioned as per drawing n°1 thereafter. Never
close your battery boxes with an excessive force applied on the screws, it will risks to damage the sealing gasket as well as damage
the box threads and there decrease the water resistance.
For activities implying the need of having fully charged emergency batteries (as for example long caving explorations activity), we
suggest you to sometimes make your rescue batteries works, it will increase their lifetime.
If you plan to travel by plane with your lamp please ensure with your flight Company that Lithium-ion batteries are allowed on flight
and ask them where and how they should be stored during the flight.
Risk of explosion: We guarantee our Ansmann branded batteries only with the use of Ansmann chargers.

Lamp mounting:
Our MEANDRE 1.0 is designed to be fixed by the means of two M5 stainless steel screws (as per drawings consigned later in the
document)
Depending on your will, we provide different types of mounting in order to fit with all possible activities. If you cannot find a mounting
solution for a special application, please contact us and we will try to propose you a solution.
Please note that for mounting your lamp on a helmet, depending on the type of helmet and mounting used, you may need to pierce
some small holes in your helmet. We underline the fact that such modification will certainly invalid the warranty of the helmet’s
manufacturer and we cannot take any responsibility about potential consequences of these modifications on your helmet.
Depending on your helmet type we can provide mounting solutions fully compatible with helmets manufacturer’s warranty, for more
information regarding this topic please contact us and provide us the type of helmet you are planning to use.

Lamp settings:
The lamp has only one push button. This push button makes it easy to switch between the five modes. Just one press will switch
from a mode to the next mode.
Switch on: Press the push button on the back of the lamp during 3 to 4 seconds. The lamp always starts in mode 1 (100 lumens)
Change of mode: Press the button once to change the light setting to the next mode.Activating the push button will change the
setting in the following cyclic way: 1-2-3-4-5, 1-2-3 …
Switch off: Press the push button on the back of the lamp during 3 to 4 seconds regardless of the mode on which the lamp is set.
Information on lamp autonomy as function of the light output settings:
The following values are resulting from tests carried out using our batteries in their delivery state at a room temperature of 20°C.
Please note that autonomy of batteries is a function of their temperature, in cold environment autonomy of your batteries will be
lower than indicated in the following table:

End of battery charge prevention:
When your battery will arrive at approximately 10% of its total capacity for the mode on which the lamp is set, a luminous signal will
inform you that your battery arrives at end of its capacity. You will then see a micro cutting in the light (during 30 milliseconds
approx.) which will repeat itself every twenty seconds. This signal will stop if you set your lamp to a lower light output and this same
signal will appear again when your lamp will be at 10% of battery capacity for this new mode.
For example, if you are using our 11.1V 5.2Ah Li-ion bat battery on mode 5 (3000lm) at 20°C, when the luminous signal will activate
itself that will mean you still have the following autonomy :
Mode 1: 14 hours
Mode 2: 2 hours and a half
Mode 3: 50 minutes
Mode 4: 50 minutes
Mode 5: 30 minutes
Depending on your activity you can decide to switch the lamp to one of the lower modes or directly replace the battery.
Warning: the discharge of the battery is not linear. It accelerates when the battery reaches the end of its capacity.

PREVENTIVE CARE
If you use the lamp for diving, cave diving, underwater activities, canyoning or all kind of activities involving consequent submersion
of the lamp in water : Always ensure, through a visual examination during your equipment preparation, that all the sealing gaskets
are in good conditions, that the lamp glass is not cracked and that your connectors (if any) are properly sealed. Deformed, damaged
of too old gaskets shall be replaced. To enhance gasket lifetime do not expose them to hot water and direct UV light (include sun
light) and periodically clean them if necessary using cold tap water and lubricate them using hydrophobic silicon based lubricant.
If you are using the lamp in highly dirt environment (such as muddy caves for example), try as far as possible to remove periodically
the excess of mud which can fill between the fins and decrease heat exchange between the lamp and its environment. This remark
is particularly important in case you want to use the high light output modes continuously.
Even if the material chosen for your lamp glass is highly resistant to impacts and therefore should not crack, such situation can be
observed in case of extremely strong shock or force applied on the glass. If you notice a crack or a consequent damage of the glass
you should then not wait and replace it.
The cable we use for the connection between our battery boxes and our lamp is highly resistant to wear but if you are often caving
or diving in caves where you have to pass through narrow passages close to abrasive minerals we would suggest you to pass your
cable mostly inside of your helmet in order to protect it from excessive wear. If during your equipment preparation you notice one or
more localized excessive wear zone on the cable do not use the lamp and contact our customer service for a cable replacement.
Be sure to charge your battery before each use. You will then be able to take advantage of the autonomy that is offered to you in
case of an unplanned event. The human eye adapts itself after few minutes to faint darkness. The progression mode (mode 2) is
thus for most of time sufficient for ensuring you a comfortable lighting in most of situations. If you need a long prolonged autonomy,
and want to avoid taking with you several batteries, use modes 3, 4 and 5 only when necessary.
If you are using your lamp in seawater always rinse your lamp with tap water after your activity as salt could generate different types
of corrosion of stainless steel screws as well as on the aluminum in contact with the stainless steel (galvanic corrosion). Seawater is
considered as a corrosive media for most of stainless steels and metallic alloys, in order to avoid such problems we suggest you to
perform an in-depth cleaning of your lamp after your diving period. Such cleaning should consists in removing the glass and opening

7
the battery boxes in order to be able to rinse the screws under tap water and gently swab the salt residues on the aluminium parts
using a wet clean cloth, ensure to let all the components dry before re-assembling the parts and take advantage of the situation to
inspect, clean and lubricate the sealing joints.
Cleaning: As the lamp is totally waterproof (except for the connector if you have chosen the IP65 one), you can clean it with a cold
tap water to remove the major part of dirt, and using a gentle brush to remove dirt between the fins and the rest of the lamp. Don’t
use an aggressive / abrasive brush to avoid scratching the glass. Washing with hot water is not recommended, it could induce
gaskets ageing prematurely.
