LED LENSER X21R.2 - Manual (Page 4)

We are delighted that you have purchased one of our products.
These are usage instructions to help you familiarize yourself with your
new purchase. All the documents accompanying the product must be
read attentively before using the product, stored for future use and if the
product is transferred to a third party, the documents must be handed
over as well. This ensures that maximum benefit is drawn from the
product and questions from users can be resolved when they arise.
Above all, comply with the warnings and safety instructions and dispose
of the packaging material properly.
Under point 13 and 14 it is explained how the lamp head is separated
from the Power Module and how the rear part of the shaft of the lamp
is unscrewed. Both actions described under point 13 and 14 must be
carried out before initial use of the lamp; they are necssary in order to
remove and dispose of the two insulating films (one on each side). These
two films serve as protection during transport of the "Safety Ytrion Cell"
battery pack.
After taking off the insulating films, you must screw the rear part to the
middle part first before pushing the switch button; otherwise the lamp
might not work properly. Now, you can screw the Power Module (rear
part plus middle part) to the lamp head.

LED LENSER
9421-R Led Lenser X21R.2
Version of the operating manual: 1.3
1. Battery set:
1 x Power Module (shaft including “Safety Ytrion Cell” battery pack); no
other batteries or accumulators are permitted
2. Turning on and off
The “Fast Action Switch“ is a selection ring located on the X21R.2 shaft
directly behind the lamp head. It is used to quickly select and use various
Light Programs and Light Functions (see Point 7). Rotating selection ring
lines up the switch button with one of 5 different symbols on the ring.
Thereby selecting different settings when the switch button is pressed.
This feature is called “Fast Action Switch“ and is further described under
Point 7 along with the various Light Programs and Light Functions that
can be selected in this manner.
In the extreme left position of the switch button, which is marked on
the selection ring by a lock symbol ( – Lock Function), the X21R.2
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.
Please note, that there are three ways of actuating the switch button:
a )Switching
When the switch button is pressed beyond the pressure point, (deep
enough so that the switch clicks into position) a small clicking sound can
be heard when the button locks into position.
b) Brief tapping
When the switch button is only tapped briefly and not pushed as deeply
as in explained above. As a result, the switch does not lock into position,
there is no audible click and the switch returns to its untouched starting
position when it is released.
c) Prolonged tapping
This is when the switch button is pressed as hard as what is described
under b), but held in the unlocked position for a longer time. Here too,
the button is not pressed as hard as under a). As a result, the switch does
not lock into position, there is no audible click and the switch returns to
its untouched starting position when it is released.
This prolonged tapping is required to be able to select 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 X21R.2. Please do not confuse it with
the switch button (see Point 10), which consists of the two concentric
charging circles at the end of the torch.
3. Focus
The focus of the X21R.2 can be quickly adjusted with the so-called Speed
Focus feature. For this purpose, hold the torch on the serrated middle
section firmly with one hand and, with the other hand, pull the reflector
lens lamp head forwards or backwards. By doing this, you can adjust the
light beam continuously to suit your needs.
4. Smart Light Technology (SLT)
The X21R.2 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 various Light Programs and Light Functions can be utilized. By using
a single switch in conjunction with the selection ring, the “Fast Action
Switch“, it was possible to keep the interface simple and user-friendly.
The torch can provide the user with light in various intensities and in
various different ways. There are 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 the
front section has to be used. Here, the switch is used in the three ways
described above in Point 2.
The brightness of the X21R.2 is additionally controlled by the built-in
temperature control unit.
5. Energy Modes
By selecting one of the two Energy Modes (Energy Saving or Constant
Current), you make a decision on how the energy contained in the
rechargeable batteries are used.
5.1 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.
5.2 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 ideal when a high brightness level is more important than a long
burn time.
6.Changing of the Energy Modes
To change the Energy Mode, the lamp has to be off and the switch button
has to line up with the second position ( ) of the “Fast Action Switch“.
Tap the button near the head of the lamp lightly 8 times. On the 9th tap,
press the button so you can hear it click. If the brightness first increases
and then gradually reduces to zero, this indicates that the X21R.2 is now
in the Energy Mode 'Energy Saving'. If after the button is pressed and the
brightness of the X21R.2 quickly increases, remains constant for approx.
2 seconds, then suddenly drops to zero, the X21R.2 is now in the Energy
Mode 'Constant Current'.
With this procedure, you can switch between the two Energy Modes
however, it is not possible to determine in which Energy Mode the X21R.2
currently is. To find this out you must carry out the procedure again. If
the X21R.2 is thereafter not in the desired Energy Mode any more, you
must repeat the procedure again.
7. Light Programs and Light Functions
As already described in Point 2, by turning the black selection ring
(with its 5 marks) below the lamp head, you can select from 5 different
settings and activate them with the switch button. The 5 positions
represent the various Light Programs or the Lock Function. The ring
uses embedded permanent magnets and thus ensures contact-less
transmission of the selection to the microcontroller in the lamp housing.
(see figure 5 on page 1)
7.1 Lock function ( )
In the first position from the left (the selection ring has been turned to
the right till it comes to a stop), the X21R.2 cannot be switched on, either
intentionally or unintentionally. Thus, the lock function is handy for when
the X21R.2 is transported. Also, there could be situations in which the
X21R.2 should not be switched on unintentionally.
7.2 Light Program Low ( )
If the switch button of the „Fast Action Switch“ is in the second position
from the left of the selection ring, you can use the Light Function Low
Power with its reduced brightness. When the lamp is switched on, it will
be initially in the Light Function Low Power. By tapping the switch when
the lamp is on, the Light Function can be switched from Low Power to
Full Power and back, thus providing light output at 10% or 100% of the
output power, respectively. Pressing the button a second time will turn
the lamp off again.
When the X21R.2 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 ( )
If the selection ring is in the third position from the left and the lamp is
switched off, pressing the button will turn on the lamp at full brightness
level (Light Function Power).
If the lamp is switched off but the button is tapped, Morse signals can
be transmitted with full brightness. If the tapping lasts for more than 3
seconds, the boost mode (130% of full brightness) will be entered. This
mode will stay on as long as the switch is held in the tapped position.
If the lamp is switched on, tapping will switch between the 100%
output level and a stored dimming level. The dimming level can be set
(Light Function Dim) tapping and holding the switch for more than 3
seconds when the lamp is on and in dim. While holding the switch, the
brightness level will cycle through all possible dimming settings. It will
slowly increase to the maximum output level, then slowly decrease to
the minimum level and finally restart the cycle and increase again. The
maximum and minimum levels in the cycle are marked by a short blink.
When the desired dimming level is reached, the switch can be released.
The lamp will continue to output light at the chosen dimming level; in
addition, the dimming level will be saved and is available the next time
the Light Function Dim is activated. The setting of the dimming remains
stored until a new level is stored by the user or when the Power Module
(shaft with „Safety Ytrion Cell“ battery pack) is unscrewed at the head
(also see the Reset function under Point 9).
