Elikliv model DM9 Digital Microscope
Enhanced User’s Manual
Overview
The DM9 is a ‘monocular’ microscope that uses a solid-state sensor element to capture an
image(s) of the subject, and a back-illuminated LCD display screen to allow viewing of the
captured image(s). A microcontroller inside the LCD display handles image processing and
display. In addition to capturing still images, the microscope also allows capturing video.
Because the microscope is ‘monocular’, it can only manage 2-dimensional images, and cannot
depict the third ‘height’ dimension, thus the user cannot perceive or judge depth in the displayed
image.
The captured still images are stored as JPEG (JPG) files, and captured videos are stored as AVI
files, with both types of files being saved to a microSD memory card (SD for short) that plugs
into the side of the LCD display (“LCD” for short). The microscope does NOT save images and
videos to the SD card if the LCD is plugged into a PC (personal computer) via a USB cable; in
that case, the photo/video capture software on the PC will handle recording of images and videos
to files, and the file types will depend on the application software used.
The microscope has an integral annular set of LEDs encircling the lens to provide illumination of
the subject; a control wheel on the LCD allows adjustment of the brightness from this light
source. The base of the microscope also has two auxiliary “gooseneck” LED lamps (henceforth
referred to as “auxiliary lamps”); these have their own dedicated brightness control wheel on the
rear of the base. Note that both brightness control wheels are poorly scaled, thus most of the
adjust occurs near one end of the control wheel rotation, the rest of the rotation being a ‘dead
zone’.
Basic Microscope Operation
Review the rest of this manual for details.
Turn on the LCD using the Power button. Turn the annual LED lamp in the microscope on or off
as required, and adjust the brightness as desired; do similarly with the Auxiliary LED lamps on
the Base. Place the ‘subject’ (the object that you will be looking at) on the Base, with the area of
interest positioned directly below the lens in the bottom end of the microscope. Adjust the Focus
Wheel near the bottom end of the microscope until the area of interest is in clear focus. To
change the magnification, raise or lower the microscope on its stand by use of the two black
knurled knobs that are on either side of the Holder by the Stand; it will be necessary to re-focus
every time the magnification is changed. Minimum magnification is obtained with the
microscope fully raised, maximum magnification requires the microscope to be fully lowered.

Power Source
The microscope and the LCD get their power from an integral, replaceable, type 18650 lithium-
ion battery, which is located behind a sliding cover on the rear of the LCD. The 18650 produces
3.7V with a capacity of about 3000mAh. Circuitry integral to the LCD boosts the battery voltage
as required, and also handles charge management of the battery. There is reason to expect that
the LCD will not charge the battery very much, if at all, while the microscope is turned on; for
best/fastest charging, the microscope should be turned off. Charging a mostly depleted battery
should take between 1 and 2 hours, assuming that a USB power adapter/charger of at least 2A
capacity is used (it is not included with the microscope and must be obtained separately). The
battery can also be charged by connecting the LCD to a personal computer (PC) via a suitable
USB cable. The cable must have a micro-USB plug on the end that will connect to the LCD.
The auxiliary gooseneck LED lamps are powered via another micro-USB socket, located on the
rear of the microscope’s Base. A PC or a USB power adapter/charger may be used as the power
source for the Base’s auxiliary lamps. Alternately, the same cable that is used to connect the
wired remote control to the LCD has a branch cable that can reach the micro-USB socket on the
Base, so that the LCD’s battery (or USB power source) also supplies power to the lamps on the
Base.
Memory
The microscope can store still images (as JPG files) and video (as AVI files) locally on a
microSD memory card that is plugged into the LCD. Any images or video saved to the SD card
can be read back and viewed on the LCD. Purportedly, any connected PC might be unable to
read the contents of the SD card while it remains plugged into the LCD, although the SD card
may be unplugged from the LCD and inserted into an SD card reader on a PC for purposes of
reading the card’s files in that manner. If the LCD is connected via USB to a PC, the
microscope’s camera can be read directly and continuously as a generic ‘PC camera’ and
whatever it sees can be viewed, manipulated, and stored on the PC.
When the LCD is connected to a PC, all pushbutton controls on the LCD and the wired remote
control are disabled, so the only access to the microscope’s camera is by way of the PC and its
software.
Because most PC’s do not have microSD card slots, it will be necessary to have a microSD to
SD card adapter, in order to transfer saved image and video files to the PC (which is not the same
thing as using the PC to directly read the microscope camera via the USB connection).
The microSD card plugs into a slot labeled “TF” on the right edge of the LCD; the card must be
oriented with any writing or logos facing forwards and the notched/serrated edge facing upwards.
Press the card into the “TF” slot until it is flush with the edge, and it should click into place. To

4
remove the card, press the end of it slightly into the “TF” slot (using a finger nail), and release it
so that an internal spring can eject it.
The microSD card must have a capacity within the range of 8GB ~ 32GB.
The SD card must be formatted by the LCD’s formatting function in order to work correctly; do
not format the SD card in any other device, unless then re-formatting is done by the LCD before
use with the microscope.
An SD card-shaped icon on the LCD’s screen, centered vertically along the screen’s right edge,
shows the status of the SD card and/or its “TF” slot. If an SD card is not installed in the LCD, or
an unformatted SD card is installed, the icon will have a red “X” across it. Once a properly
formatted SD card is installed in the LCD, the red “X” will disappear and just the shape of the
SD card will remain as the status icon. Note that after formatting an SD card, the icon will
continue to show the red “X” until any active menu has been closed.
On occasion, when trying to save/record an image or a video to the SD card, the LCD display
might show a message about there being “No SD Card” (or similar) even though a formatted SD
is in fact inserted into the LCD. When this happens, eject the SD card and re-insert it, giving the
LCD controller a few seconds to evaluate the card and update the screen icon.
Power & Battery Charging
The LCD has a small round LED located just above the three buttons at the lower right corner of
the screen. It lights up red when the battery is charging, or green when the battery has been fully
charged, and flashing blue when the LCD’s integral controller circuit is functioning correctly
(the LCD must be turned on (powered up) for the LED to light up as flashing blue).
To turn the LCD on (this includes the microscope itself), press the POWER button for about 2
seconds. To turn the LCD off, press the POWER button again for about 2 seconds.
At the lower right of the display screen is an icon that looks like an ‘A’ cell (battery). This is the
battery charge level indicator, and it will be filled in when the battery is fully charged, and
should be progressively less filled in as the battery’s charge is depleted. When the battery is
being charged via USB power, this same icon will change to show the image of an AC power
plug superimposed over the battery symbol, and the composite icon will flash.
Assuming that the battery is mostly depleted, it should take between 1 and 2 hours to fully
recharge, assuming power is coming from a USB power adapter/charger of at least 2A capacity.
Sometimes the LCD’s controller might ‘crash’ or otherwise lock up, and all buttons are likely
to become unresponsive and the display screen might show a static image. In this situation, it

5
will be necessary to reset the controller. Press and hold the POWER button for perhaps 20
seconds, or until the display screen changes, then allow the LCD to power up normally again.
Parts of the Microscope
To clarify the terminology/nomenclature used, the following part names are used:
-“LCD”: this is the microscope/LCD assembly
-“Holder”: this is the metal bracket that mounts to the “Stand” on its rear end and into
which the microscope body fits on the front of the “Holder”
-“Stand”: this is the vertical post that the “Holder” & “LCD” raise and lower on
-“Base”: this is the metal plate which supports the “Stand” and the two auxiliary
gooseneck LED lamps
The names of the major parts are listed below:
LCD
-7” diagonal backlit color LCD display, actual image is about 153mm wide
-Microscope with integral lens, surrounded by an annular array of LEDs, and with a
transparent lens protector
-Focusing wheel located just above the bottom end of the microscope
-Battery cover on the rear of the LCD, slides down to open and detach
-Lithium-Ion battery, type 18650, under the battery cover
Holder
-The front ring of the Holder has two small thumbscrews for securing the microscope that
passes through the ring from the top
-Two large magnification adjusting thumbscrews, located at the rear of the Holder, a
pinion gear inside the rear of the Holder engages the rack on the front edge of the Stand
-Magnification adjustment friction thumbscrew, which presses against a friction pad that
slides inside an extruded groove on the rear of the Stand’s post
-
Stand
-The vertical post screws into a threaded hole on the top-rear of the Base, and is secured
using a knurled locking ring (similar to a jam-nut)
-The vertical post has a threaded rack running vertically along the post’s front, which is
engaged by the pinion gear on the Holder

6
Base
-At the top rear corners of the Base are the mountings for the two auxiliary gooseneck
LED lamps
-Under the rear edge of the Base is a plastic enclosure which houses the electronic
dimming circuit for the auxiliary gooseneck LED lamps. A microUSB connector allows
5VDC power to be applied for use by the two lamps. A small knurled brightness control
wheel allows adjustment, from OFF to full brightness, of the two auxiliary lamps. Note
that most of the control’s rotation has no affect on the lamp brightness, with its effective
range being a small portion of the rotation
Light Barrier
-The Light Barrier is a metalized plastic ring that can be used to replace the normal
“transparent lens protector” that normally surrounds the lens.
-The “transparent lens protector” fits tightly, but can be removed from the microscope by
firmly pulling down (away from the body of the microscope) while also using a wiggling
or rocking motion.
-Once the “transparent lens protector” has been removed, the Light Barrier can be attached
to the microscope using a ‘bayonet’ action; press it up against the bottom of the
microscope near the lens, and twist about 45 degrees to lock it in place.
-The function of the Light Barrier is to reduce reflection when using the microscope for
doing micro-soldering, for example of SMD electronic components on a printed circuit
board.

Menu
The microscope can be configured in many ways by use of a menu that is integral to the LCD.
-To enter the Menu, press the “M” button on the bottom edge of the LCD, or alternately
press the [M] button on the wired remote control; this will bring up the menu.
Henceforth, this text will simply refer to “M” to mean either of the two buttons described
above.
-The menu is divided into two tabs, one being for camera settings (either Still or Video,
depending on the currently selected mode) and the other being for general microscope
settings; the Camera menu (represented by a camera shaped icon) is the first to be
selected by the above step. Make any desired camera settings and configurations here.
-There are actually three versions of the Menu, and the one you see depends on which
mode the microscope is in: Still, Video, or Playback. The following Menu description is
based on the appearance of the Menu while the microscope is in the Still mode.
-Pressing “M” will change the menu from the Camera to the General Settings menu
(represented by a wrench-shaped icon). Make any desired non-camera settings and
configurations here.
-Pressing “M” again will exit the menu and return the LCD to normal operation.
oUse the ^ and v buttons on either the LCD, or the wired remote, to select options
within each of the two menus.
oPress the “OK” button on the LCD, or the Camera icon/OK button on the wired
remote, to open the currently selected option. Henceforth, “OK” will refer to
either method.

screen’s backlight off if no buttons are pressed during the
selected time period
oThis option can be turned on while the more general
Automatic Shutdown (see above) is turned off, and thereby
function as a semi-battery saver
oThis option, if turned on, might be confusing because if the
screen goes blank, the user might not be able to easily tell
whether the microscope is turned off, or if it is turned on
but the screen is turned off
Language Selection. The choices are:
•English (default)
•Portuguese
•Simplified Chinese
•Japanese
•French
•German
•Korean
•Italian
•Dutch
•Russian
•Spanish
•Arabic
oUse ^ and v buttons to select the desired option, then press
“OK” to select and return to the menu

11
Light Source Frequency. The choices are:
•50 Hz (default)
•60 Hz
oUse ^ and v buttons to select the desired option, then press
“OK” to select and return to the menu
oThis selection changes the microscope’s operation to
minimize visual artifacts (banding, etc) in recorded videos,
as a result of ‘beat frequency’ interaction with area lighting
which invisibly pulses rapidly according to the AC line
frequency in the part of the world where the microscope is
being used; set according to the local AC line frequency
oThis may also be influenced by, or associated with, the TV
video standard used in the part of the world where the
microscope is being used; the PAL video format is mostly
used where 50Hz AC power is used, and the NTSC video
format is used on many areas where 60Hz AC power is
used
Line Assist. The choices are:
•Off (default)
•On
oUse ^ and v buttons to select the desired option, then press
“OK” to select and return to the menu
oThe purpose of this option is unclear, and is not described
in the DM9 product’s Instruction Manual. However, a
different Instruction Manual for the similar Elikliv DM3
microscope briefly mentions this feature without actually
describing its function
oBy empirical experimentation, this Line Assist option, if
turned on, simply places a crossed pair of vertical and
horizontal red lines on the screen image, something like a
target cross-hair. However, the red cross-hairs do not seem
to be stored as part of the still and video files, so they do
not appear in Playback of still images or videos
Formatting (of the microSD card)
•To use this menu option, there must be a microSD card inserted
into the “TF” slot on the LCD
oSelect Cancel (default) or Confirm
oIf confirmed, it will probably be necessary to re-confirm,
because proceeding will erase all photos and/or videos on
the microSD card
oA message “Hold On” appears while the microSD card is
re-formatted/erased

12
oIt is necessary to use the LCD to format the microSD card
before the LCD will recognize it as a valid memory device
for storage of still image and/or video files; formatting the
SD card in a personal computer will probably result in the
LCD not recognizing the SD card
Default Setting. The choices are:
•Cancel (default)
•Confirm
oIf confirmed, the LCD will set all menu options back to
their defaults
oIf cancelled, all menu options will remain as set by the user
Version
•Pressing “OK” shows the LCD’s current firmware revision level
•Pressing “OK” a second time will return to the menu
oIf there is a method for updating the firmware, it is not
described in the User’s Manual, and is not apparent from
the context of the menu
Selecting the Mode
-Press “M” on the LCD (or “[M]” on the wired remote) for 3 seconds (or, briefly
click/press the [>] button on the wired remote) to cycle between the following three

Connecting to a PC
The microscope’s integral camera can be used as a camera for a PC, either Windows or Mac.
Connect a USB cable (having a microUSB plug on one end) into the LCD’s ‘DC5V’ jack. The
PC will now power the microscope. Note that some USB cables only have two wires inside, and
are only useful for providing USB power to devices; make sure to use a USB cable that is fully
wired and thus can be used for USB communications.
On a Windows PC, run the “Windows Camera” or similar function (details of this will vary with
the version of Windows). If the PC does not have this application, it might be necessary to do a
Google search to find a download for “Windows Camera” and install it. With the application
ready in Windows (but not yet running), connect the microscope LCD to the PC, and a menu will
appear on the LCD, showing options for “Mass Storage” (the PC can access the files stored on
the LCD’s installed microSD memory card), “PC Camera”, and “Charging Mode” (where the
PLC is only being used as a USB power source for the microscope, not for communication).
Select the “PC Camera” option and Confirm. Start the “Windows Camera” application on the
PC, and it should detect the microscope and should show a real-time display, and the
microscope’s image can be viewed on the PC, and recorded (still image and video). If the PC’s
“Windows Camera” software does NOT automatically detect the microscope (and there might be
an error message), unplug the USB cable from either the PC or the LCD, and plug it back in
again.
On an Apple PC such as a MacBook or an iMac, make sure that the PC already has the “Photo
Booth” application installed; if not, download it from the Apple ‘App Store’. Connect the
microscope LCD to the PC using a USB cable (it may be necessary to use a USB hub if the PLC
does not have enough USB sockets available). A menu will appear on the LCD, showing options
for “Mass Storage” (the PC can access the files stored on the LCD’s installed microSD memory
card), “PC Camera”, and “Charging Mode” (where the PLC is only being used as a USB power
source for the microscope, not for communication). Select the “PC Camera” option and Confirm.
On the PC, start the “Photo Booth” application (Finder > Application > Photo Booth) and choose
“General – UVC #2 (Default)” on the menu bar.
Note that when the LCD is plugged into a PC via a USB cable, all pushbuttons on the LCD and
the wired remote control are inactive. Use the PC software to interface with the microscope, take
pictures and videos, and optionally access the microscope LCD’s microUSB memory card.

A Note on the Magnification
The Amazon listing for this microscope, and the “Instruction Manual” included with the
microscope, both specify the magnification as 50x minimum and 1200x maximum, a ratio of
roughly 24. By contrast, the “Instruction Manual” specifications page gives the ‘magnification’
as “500/1000”, a ratio of 2; a big difference between this and 24!
The author of this “Enhanced User’s Manual” has done empirical evaluation of the actual
magnification. A thin metal ruler with 1mm graduations was placed on the Base and the
microscope’s “transparent lens protector” was lowered until it touched the ruler, then the focus
wheel was adjusted for a clear image on the LCD screen. A distance of approximately 2.14mm
on the ruler was magnified to take up the entire width of the screen. Then the microscope was
raised on its stand as high as it would go, and the image was focused once more. Now a distance
of approximately 14.5mm was magnified to take up the entire width of the screen. This gives a
ratio of about 6.8, again quite different from the ratios of 24 and 2 given in the “Instruction
Manual”. Based on these measurements, the microscope’s maximum magnification, subject-to-
screen (the screen is 153mm wide), is 153/2.14 = 71.5x, and the minimum magnification is
153/14.5 = 10.5x ….. so the magnification specification SHOULD BE 10.5x ~ 71.5x.
