“Power” button (3). A red LED will light up under the button and shortly the screen 

will light up as three LEDs will illuminate the screen. To change the LEDs (the default 

setting is 3 LEDs on), press the “Up” button for 6 LEDs on. Press the button again, 

and the LEDs are turned off. To turn off the microscope, press (on some units press 

and hold) the “Power” button, and the screen will show “Shutting Power Off”. To 

change from Viewing Objects/Taking Snapshots to Taking Videos to Review Images, 

press the “M” button to rotate to the desired function.

A. Viewing Objects 

— To view objects, use the Viewing/Snapshot mode.

1. 

Icons seen on the LCD Screen

 — in the top right, “A” indicating viewing 

mode. In the top left, shows battery condition. The bottom right shows the 

resolution selected as well as the number of images available (to take) at 

the chosen resolution. Also at the bottom right, is “M” or “SD” (or similar 

designations) to note if internal memory or an optional SD Card is being 

used. On the left side, digital zoom power is displayed (if using this function).

2. 

Focusing and changing Power

 — use the Focus Ring (8) to change power 

and focus to see a sharp image. You can rest the LED Cover (9) directly on/

over an object to view. Always start with the low power (3.7x) by rotating 

the focus ring to the far left and move the ring slightly to get a sharp focus. 

The most enjoyable views may be seen at low power which has a wider 

field of view and a brighter image. To achieve an even lower power setting 

(varying from 3.7x down to 1x),raise the microscope above the object. As 

the microscope is raised higher and power decreases, refocusing may be 

necessary. To change to high power (54x), rotate the Focus Ring all the way 

to the right and turn the ring slightly to obtain a sharp focus. You must use 

the high power directly on or slightly above an object to obtain a sharp 

focus. For low power, the three LEDs should be adequate, but you may 

need six LEDs when using high power to illuminate the object. Remember 

that using all six LEDs reduces the life of the batteries. To achieve higher 

powers than the standard low and high power, you can use the digital 

zoom feature by pressing the “Down Button” in the Viewing or Video 

modes. Pressing once will go to 2x digital zoom and pressing again will go 

to 4x. Pressing the button again reverses the zoom function. This feature 

gives you additional benefit by allowing you to digitally magnify an image 

to make it more enjoyable on some objects.

B.  Taking Snapshot Images

 — To take snapshots, you must be in the Viewing/

Snapshot mode. Press the “Snapshot/Video Button”, and the images will then 

be stored in internal memory or on an SD Card if using one.

C. Taking Videos

 — To take videos, you need to be in the Video Mode (the video 

icon will be in the top right of the LCD screen). Once the image is in focus, 

press the “Snapshot/Video Button” (4) and recording will begin. To stop the 

recording, press the same button again. The time of the video as it is being 

recorded, is shown at the bottom of the LCD. 

D. Using an SD Card

 — You can also take images (snapshot or video) by using an 

SD (Secure Digital) Card. Your SD card is inserted in the SD Card Slot (10) on the
