We are delighted that you have purchased one of our products.
These are usage instructions to help you familiarise yourself with your new purchase. All the documents accompanying the product must be read
attentively before using the product, preserved carefully and if the product is transferred to a third party, the documents must be handed over as well.
This ensures that maximum benet is drawn from the product and questions from users are anticipated before they arise.
Above all, comply with the warnings and safety instructions and dispose of the packaging material properly.
Under point 13 and point 14 it is explained how the lamp head is separated from the Power Module and the rear part of the shaft of the lamp is
unscrewed. Both must be carried out before the rst use, so that the two insulating lms (one on each side) can be removed and disposed of. These
two lms serve as protection during transport of the "Safety Ytrion Cell" battery pack.
After taking off the insulating lms, be sure not to push the switch button when assembling the lamp. First, screw the rear part to the middle part-
otherwise the lamp might not work properly. Then screw the Power Module (rear part plus middle part) to the lamp head.

LED LENSER
8317-R Led Lenser M17R
Version of the operating manual: 1.0
1. Battery set:
1 × Power Module (shaft including “Safety Ytrion Cell” battery pack); no other batteries or accumulators are permitted
2. Switching on and off
In the front section of the M17R, directly behind the wide head, is the selection ring of the “Fast Action Switch”, in the groove of which the switch button
is located. The name “Fast Action Switch” describes the facility provided by this switch system to quickly select and use various Light Programs and
Light Functions (see Point 7). Turning the selection ring of the “Fast Action Switch” changes the position of the switch button in the groove. Its position
can be adjusted so that it clicks into place in 5 different settings. These positions represent the various Light Programs (see point 7).
In the extreme left position of the switch button, which is marked on the selection ring by a lock symbol ( – Lock Function), the M17R is protected
against accidentally getting switched on. In all the other positions, it can be switched on and the various Light Functions can be used.
What is important here is that there are three ways of actuating the switch button:
a) Switching
The switch button is pressed beyond the pressure point, i.e. so deep that the switch clicks into place. A small sound, a click, can be heard.
b) Brief tapping
The switch button is only tapped briey and not as deeply as in a) above. As a result, the switch does not click into place, there is no click audible and
the switch remains in the starting position when it is released.
c) Prolonged tapping
The switch button is pressed as under b), only slightly but for a longer time.
Here too, the button is not pressed so hard as under a. As a result, the switch does not click into place, there is no click audible and the switch remains
in the starting position when it is released.
This prolonged tapping is required, e.g. to be able to make various settings (see Point 7 and 8).
The descriptions above apply to the switch button of the “Fast Action Switch” in the front section of the M17R. Please do not confuse it with the switch
button (see Point 10), which is formed by the two concentric charging contacts at the end of the torch.
3. Focus
The focus of the M17R can be quickly adjusted with the help of the so-called Speed Focus. For this purpose, hold the torch on the serrated middle
section rmly with one hand and with the other hand, push the wider lamp head in which the reector lens is located, to the front or to the back. By
doing this, you can adjust the light beam continuously variably to suit your needs.
4. Fast Lock
If required, a desired focus setting can be locked by means of the so-called Fast Lock. What this does is to prevent the focus setting from getting
accidentally changed. To do so, the lamp head must be turned left with respect to the shaft, i.e. in the direction of the legend “Lock” on the lamp head.
To release this xed setting and to once again allow the continuously variable setting of the focus (see Point 3), the lamp head has to be turned in the
other direction, i.e. the direction of the legend “Unlock”.
5. Smart Light Technology (SLT)
The M17R is equipped with our Smart Light Technology (SLT). Thanks to the use of a microcontroller, the light output of the LED can be controlled and
the user can use various Light Programs and Light Functions. By using a single switch in conjunction with the selection ring in the “Fast Action Switch”,
it was possible to design the interface to be simple and user-friendly. The pocket torch can give the user light in various intensities and in various
different ways. There are thus two Energy Modes, four Light Programs and a number of Light Functions available. To switch the pocket torch on and
off and to select the various Light Functions, the switch in its front section has to be used. Here, the switch is used in the three ways described above
in Point 2.
What basically applies is that the brightness of the M17R is monitored by the in-built temperature control unit.
6. Energy Modes
By selecting one of the two Energy Modes (Energy Saving or Constant Current), you take a decision on how the energy contained in the accumulator
is used.
1. Energy Saving: The light output is controlled by the integrated Smart Light Technology (SLT). The brightness is matched to the real conditions that
occur during normal use of the lamp, thus providing a longer burn time.
2. Constant Current: This Energy Mode allows the continuous use of all the Light Functions with a more or less constant light output. This Energy
Mode is to be preferred when a high brightness level is more important than a long burn time.
Changing of the Energy Modes
For changing the Energy Mode, the lamp has to be off and the switch button must be in the second position ( ) of the “Fast Action Switch”.
If you now tap the switch button on the lamp head lightly 8 times, followed by a switching operation, and then the brightness increases jerkily, to later
reduce gradually to zero, the M17R is in the Energy Mode 'Energy Saving'. But if the brightness of the M17R remains constant for approx. 2 seconds
after the sudden increase, to then suddenly drop to zero, the M17R is thereafter in the Energy Mode 'Constant Current'.
With this procedure, you can switch between the two Energy Modes. It is not possible to determine in which Energy Mode the M17R is. To nd this out,
you must carry out the procedure. If the M17R is thereafter not in the desired Energy Mode any more, you must repeat the procedure again.
7. Light Programs and Light Functions
As has already been described in Point 2, by turning the black selection ring (with its 5 marks) below the narrowing point of the lamp head, you can
select from between 5 different positions and activate them with the switch button. The 5 positions represent the various Light Programs or the Lock
Function. Thanks to the permanent magnets that are embedded in the selection ring of the “Fast Action Switch”, the ring slides over the lamp housing
when it is turned, and thus ensures contact-less transmission of the selection to the microcontroller in the lamp housing.
7.1 Lock function
In the rst position from the left (the selection ring has been turned to the right till it comes to a stop), the M17R cannot be switched on, either
˚ English ˚ English
intentionally or unintentionally. Thus, the lock function is handy for when the M17R is transported. Also, there could be situations in which the M17R
may/should not be switched on, even unintentionally.
7.2 Light Program Low
If the switch button of the “Fast Action Switch” is in the second position of the selection ring, you can use the Light Function Low Power with its reduced
brightness. By briey tapping and letting go, you can switch to the Light Function Power with full brightness. When you tap it again, you can switch
between the Light Programs Low Power and Power. One more switching operation, and the lamp is off.
When the M17R is off, tapping can be employed, e.g. to send signals of various length in Morse code with reduced brightness.
7.3 Light Program Action
In the third position of the selection ring, by switching or tapping, the Light Function Power (full brightness) is immediately usable. As with Light
Program Low, here too, it is possible to use tapping for sending Morse signals, but with full brightness in this case.
Upon switching, the Light Function Power is rmly set and by brief tapping, it is possible to switch between the Light Functions Power and Dim.
Upon switching to ‘Dim’ by tapping, if the switch button remains tapped for a longer time (prolonged tapping), the M17R starts to slowly change the
brightness between low brightness and full brightness. The lamp will extinguish for one short moment if the brightest or lowest luminosity is reached.
Upon releasing the switch, the M17R continues to glow with the current brightness level. This brightness level remains saved, i.e. remains set for the
light function Dim, when the M17R is switched off. This brightness of the light function Dim is only lost, or changes, when the Power Module (shaft
with “Safety Ytrion Cell” battery pack) is unscrewed at the head (also see the Reset function under Point 9). Of course, it also changes if specically
changed by the user as described above.
One more switching operation, and the lamp is off.
7.4 Light Program Signal
In the fourth position, by switching or tapping, the Light Function SOS (3 short, followed by 3 long, followed again by 3 short ashes) can be invoked
immediately.
If, after a switching operation, the switch is tapped, the Light Function Blink (slow, continuous blinking) is activated. Tapping once again results in the
Light Function Signal Blink (2x blinking at short intervals)
One more switching operation, and the lamp is off.
7.5 Light Program Defence
The Light Mode Defence is the one on the extreme right on the selection ring; it can be selected by turning the selection ring completely to the left till it
comes to a stop.
Upon switching, the Light Function Strobe is set and by tapping briey, it is possible to toggle between Strobe and Power.
One more switching operation, and the lamp is off.
Here, too, the Light Functions are revolving, like with the Light Modes 2, 3 and 4. This means, for example, with Light Program 5, that after the Light
Function Power, one more tap leads to the Light Function Defence. Thus, tapping does not take you into a dead end; there is a continuous circular
series of selected light functions.
When the M17R is glowing in one of the Light Functions (2, 3 4 or 5), it also glows after a changeover (by turning the selection ring of the “Fast Action
Switch”) between these 4 Light Functions. With such a changeover, the M17R has the light function that it also had when switched on directly (e.g. with
the Light Program Signal, the Light Function SOS).
8. Emergency Mode / Emergency Light Function
When the Emergency Mode is activated, the M17R has an emergency light function. For this purpose, the mode has to be activated and the M17R
has to be connected to the charger (position light at the charger glows blue, see Point 10). In this case, the pocket torch automatically goes on when
the electric supply that is providing energy to the charger fails. If positioned meaningfully, the M17R, when it is glowing, can facilitate quickly nding
an escape route in an emergency, or the lamp can be quickly found and picked up, already on. If this function is active, the M17R glows automatically
even if the charging process is interrupted by removing the M17R. Therefore, the function can also be used when the M17R has to be ready for
immediate use.
To set the Emergency Mode, set the “Fast Action Switch” to Light Program action and tap prolonged for about 10 seconds. The M17R glows for these
10 seconds and then blinks. After blinking, the light turns off. When it ashes 4 times, Emergency Mode is activated; if it ashes twice, Emergency
Mode is disabled. If this procedure is carried out again, the setting toggles between activated and disabled and signals this by a corresponding
blinking.
9. Reset function
If the Power Module (shaft with “Safety Ytrion Cell” battery pack) is unscrewed completely at the head and the two parts are screwed together again
only after a little while, you have "reset" the M17R. You have thus reset a few functions:
- As Energy Mode, Energy Saving is active (see Point 6).
- The Emergency Mode (see Point 8) is active.
- This lamp function Dim (see Point 7.3) is set to the lowermost brightness
10. Charging
The Power Module (shaft without lamp head) contains the “Safety Ytrion Cell” battery pack, the accumulator.
Charge your M17R only in a dry place.
For charging, connect the mains plug on one side to the accompanying charger (Input: 100 V to 240 V / 50 Hz to 60 Hz) and on the other side, to a
power socket. Then connect the extension cable of the charger to the cable of the magnetic charging socket, whose blue position light then starts
to glow. You can now connect the concentric charging contacts at the end of the M17R to the magnetic charging socket. When the lamp has been
correctly connected, the charging display glows red (see Point 11) and the charging starts. The Power Module (shaft with the “Safety Ytrion Cell”
battery pack) with the unscrewed lamp head can also be charged.
See the following section on the subject of the charging indicators (see Point 11) for more information.
Note – Please ensure that there is no short-circuit at the charging contacts. The charging contacts may not be touched with moist or metallic objects.
The magnetic charging socket can also be inserted in the cylindrical part of the charger bracket, which is a part of the supplied kit, and then locked in
place by turning a couple of times in the counter-clockwise direction like a bayonet catch. The lock is released by rotating in the other direction. The
bracket can be fastened on the wall with dowels (not scope of delivery) in such a way that the blue position lamp of the magnetic charging socket, for
example, glows downwards. Please use a sufcient number (min. 4 pieces) and suitable dowels, depending on the material of the wall.
The orientation described suggests itself when you wish to use the Emergency Module / Emergency Light function (see point 8) since the M17R glows
upwards in case of a power failure. On the other side of the bracket, the M17R can be joined to the bracket with 2 rubber rollers and xed permanently
by using the rubber gusset that is located at the level of the two rubber rollers. The latter suggests itself if there are acceleration forces acting on the
M17R. In this manner, the M17R can be xed in the bracket inside the vehicle if the charger bracket is xed permanently to a vehicle.
Using an optionally available car charger connection, the M17R can also be charged at the cigarette lighter and sockets in the vehicle. These
accessory units match themselves automatically to the respective input voltage (12 V to 24 V).
11 Charge indication
Approx. 2 cm before the end of the shaft of the M17R, there is a narrow ring, which, during the charging process, indicates the charge status of the
battery through lamps of different colours.
04
03

Red (glowing continuously) – charging ongoing.
Green (glowing continuously) – Charging completed, the M17R is ready for use with the full capacity of the battery. It generally takes 2 to 3 hours for
an empty M17R to get fully charged.
No light– The cause of this can be that the Floating Charge System Pro is not getting adequate electric power. But it can also be that there is a loose
contact. Therefore, check whether (magnetic) objects or dirt are hindering a good contact between the charging contacts at the end of the M17R and
the magnetic charging socket. If required, remove them. If required, also correct the position or the angle of the M17R in the charging socket. If, given
an adequate electric power supply, the charge indicators still do not glow, immediately isolate the transformer or the optional car charger of the M17R
from the present power supply system and get in touch with your dealer.
12. 360° Power Indicator
The 360° Power Indicator consists of 10 blue-glowing elements, which are arranged in a circle around the two concentric charging contacts at the end
of the shaft of the M17R.
During use, the number of blue-glowing elements reduces further and just before the Power Module is empty, the last element glows in red.
Depending on when the charging contacts are pressed, the following can be determined from the number of elements glowing.
1.) Battery status indication
If the charging contacts are pressed while the M17R is off, the elements serve as a battery charging status indication. If, for example, all the 10
elements briey glow blue, the M17R is fully charged.
2.) Operating time indication
If the charging contacts of the M17R are pressed while the M17R is being operated with a Light Function, the number of glowing elements provides an
indication of the remaining relative lighting duration of the current Light Function.
The M17R also shows this information for a brief moment when a light function has been selected by tapping or switching at the “Fast Action Switch”, i.e.
even without the 360° Power Indicator having been actuated.
13. Changing the Power Module
Please charge the rechargeable battery in time. If the Power Module exhibits any atypical behaviour, please change it. For changing this accumulator,
please rst switch off the pocket torch without fail, and unscrew the part behind the “Fast Action Switch”. You have thus separated the lamp head from
the Power Module (shaft including “Safety Ytrion Cell” battery pack). For the disposal of the used Power Module, please read Point 14.
Screw on a new Power Module onto the lamp head till it cannot be turned any more. Thanks to the innovative new contact system and the xed
connection between the lamp shaft and the “Safety Ytrion Cell” battery pack (Power Module), transposition of the polarity is not possible.
14. Rechargeable batteries / Accumulators
Only the correspondingly approved LED LENSER Power Module, consisting of the “Safety Ytrion Cell” battery pack and shaft, may be used in this
pocket torch. The Power Module was developed to ensure the highest level of safety and benet.
If you have separated the used Power Module from the lamp head as described in Point 13, please unscrew the rear part of the shaft at the level of
the charging display. You will then see a PCB of the “Safety Ytrion Cell” battery pack on this side as well, upon looking into the tube. The PCB is held
in place on this side in the shaft by a narrow plastic ring with thread. For removing the “Safety Ytrion Cell” battery pack from the shaft, unscrew this
plastic ring from the shaft. For doing so, use the two grooves in the plastic ring that are displaced 180° from one another but make sure that that you
do not short circuit the contacts of the “Safety Ytrion Cell” battery pack. The “Safety Ytrion Cell” battery pack can now be easily removed and disposed
of in keeping with the national laws. The shaft can be disposed of in the domestic trash.
In contrast to the Power Module (shaft with “Safety Ytrion Cell”), a replacement of a “Safety Ytrion Cell” battery pack in a Power Module may not
be carried out. Neither is it permitted, after removal of the “Safety Ytrion Cell” battery pack, to charge it in any other manner or instead, to use
accumulators or batteries in the Power Module. The Power Module may only be opened once, for separate disposal of the Ytrion Cell battery pack and
the shaft; otherwise, the manufacturer’s warranty will be rendered null and void.
In general, for the disposal of batteries as well as particularly for Lithium batteries, accumulators and accumulator packs, the applicable rule is that
they may only be disposed of in discharged state and in a technically correct manner. If they are not discharged, then before disposal, by sticking non-
conducting adhesive tape over the contacts, it has to be ensured that short-circuits are not possible.
Basically, the possibility of short-circuits of accumulators and batteries must be eliminated and they may neither be opened, nor enter the human body
in any way, nor may they be thrown into a re.
15. Cleaning
For cleaning, please use a dry, lint-free clean cloth.
If salt water is spilled on the lamp, it must be immediately entirely removed with such a cloth.
If it is not possible to rotate the selection ring of the “Fast Action Switch” smoothly any more, it must be separated from the M17R, and the underside
and the lamp tubes cleaned of dirt. To do so, with the screws, separate the lamp head from the Power Module. Carefully remove the black O-ring of
rubber that is located above the lamp head thread. When the switch button is now pressed deep, the selection ring can be removed over the switch
button in the direction of the thread. Please ensure here that the small spring-loaded ball including its casing above the switch button is not lost.
Both surfaces can now be cleaned and the parts can be assembled again in the opposite sequence.
If the reector lens has got loose in the lamp head or, e.g. dirt has got deposited on its inner side, you can apply the following remedial measures.
The foremost one centimetre of the M17R, with the 12 indicated holes along the periphery, can be unscrewed. There is a plastic ring that xes
the reector lens in it, and it can be tightened or removed for cleaning. You can clean the reector lens if required, with a dry, lint-free clean cloth.
Thereafter, please assemble everything in the opposite sequence.
16. Scope of delivery

17. Caution:
Do not swallow any small parts or batteries that are present. The products or parts thereof (including batteries) must be stored outside the reach of
children.
For reasons of safety and approval (CE), the product must not be modied and/or changed. The product is to be used exclusively as a pocket torch.
If the M17R is used for any other purpose, or used incorrectly, it can get damaged and hazard-free use is not guaranteed any more (danger from re,
short-circuit, electric shock etc.). There is then no liability for harm to persons or damage to property, and the warranty of the manufacturer is also
rendered null and void.
The temperature range in which the M17R can be operated is -20 C° to +50 C°. Ensure that the M17R is not subjected to extreme temperatures,
intense vibrations, explosive atmosphere, solvents and/or , vapours. Also continuously exposed to direct sunlight, high humidity and/or moisture have
to be avoided.
Changes, repairs and maintenance over and above those described in the documents accompanying the product may only be carried out by
authorised technical personnel.
Once it is found that the product is charged and correctly screwed/closed, but nonetheless, normal, safe operation is not possible or the product shows
damage, it must be rendered inoperative and not used any further. In this case, for warranty matters, contact your dealer.
18. Safety instructions
• This product is not a children's toy.
• Since it has small parts that can be swallowed, it is not suitable for persons below 5 years.
• The article may not be used for examinations of the eyes (e.g. for the so-called pupil test).
• When using it, the accumulation of heat, e.g. by covering, must be avoided.
• If the product does not work correctly, the rst thing that must be checked is whether this is due to a discharged battery or because the shaft and the
lamp head are not screwed tight enough together.
• If using in trafc, please follow the respective legal regulations.
• Owing to the permanent magnets in the selection ring of the “Fast Action Switch” and in the magnetic charging socket of the Floating Charge System Pro,
both the parts must be at a safe distance to, for example, heart pacemakers or magnetic storage media.
The hazard that poses the main threat in this product through optical radiation is the Blue-Light-Hazard (400 nm to 780 nm). Thermal hazard threshold
values are clearly not reached.
The risk for the viewer depends on the use or on how the product is installed. However, there is no optical hazard as long as the aversion responses
limit the time of exposure and as long as the information contained in this instruction manual is observed.
The aversion reactions are triggered by the exposure and they are to mean all natural reactions that protect the eye from hazards through optical
radiation. This includes in particular conscious aversion reactions such as eye or head movement (e.g. turning away).
When using the product it is of particular importance to bear in mind that the aversion reactions of persons at whom the light is directed at may be
weakened or completely suspended as a result of medication, drugs or illness.
Because of the blinding effect of the product, improper use may lead to reversible, i.e. temporary impairment of sight (physiological blinding) or
afterimages, or it may trigger feeling unwell in the sense of feeling queasy and tired (physiological blinding). The intensity of the temporary feeling of
being unwell or the time until it subsides depend primarily on the difference in brightness between the blinding-light source and the surrounding area.
Photosensitive persons in particular ought to consult a medical consultant prior to using this product.
As a matter of principle the rule is that high-intensity light sources carry a high secondary hazard potential due to their blinding effect. Just like
looking into other bright light sources (e.g. headlights of a car), the temporary limited impairment of vision and afterimages may lead to irritation,
inconveniences, impairments and even accidents, depending on the situation.
The information applies to the use of a single product. If more light-emitting products of the same type or of a different type are used together, the
intensity of the optical radiation may increase.
Every longer viewing/eye-contact with the source of radiation of this product by the user or other persons, with and without other light-bundling
instruments, is to be avoided as a matter of principle! Instead, the eyes are to be closed deliberately in such cases and the head ought to be turned
away from the light beam.
In case of a commercial use or the product’s use by public bodies, the user must be instructed as to all applicable laws and regulations that correspond
to the individual case of usage.
Important rules of conduct:
• Do not aim the light beam directly into the eyes of a person.
• The user or any other person should not look directly into the light beam.
• In the event of optical radiation hitting the eye, the eyes must deliberately shut and the head is to be turned away from the beam.
• The instruction manual and this information must be stored safely and must be passed on together with the product.
• It is prohibited to look straight into the light that is being emitted by this product.
