Interpupillary distance is the distance between the 
eyepieces of a binocular. Easy adjustment will ensure
that your binoculars are giving you the view you
want. To adjust interpupillary distance, follow these 
simple steps:

1.

  Hold binoculars in the normal viewing position.

2.

  Grasp each barrel firmly.

3.

  Gently move the barrels closer together or farther  

     apart until you see a single circular field.

4.

  When your view appears as a single circle, the  

     interpupillary distance is correct. Note the settings
     for easy adjustment in the future.

INTERPUPILLARY DISTANCE

CENTRAL AND DIOPTER FOCUS

USING YOUR

ZHUMELL BINOCULARS

To get the most from your Zhumell binocular, take 
some time to acquaint yourself with its features 
and settings. Customizing each setting for you and 
your eyes will lead to the most satisfying experience 
possible with your new optical equipment.

1.

  Start by setting the diopter ring (for most models,  

     it will be located on the right eyepiece) to zero ( - ),   
     then select a distant object to view.

2.

  Cover the right objective lens with your hand or a  

     lens cap and rotate the center focus wheel until  
     the image in the left eyepiece becomes sharp.

3.

  Cover the left objective lens and rotate the diopter

     ring on the right eyepiece until the image in the  
     right eyepiece becomes sharp.

4.

  Now, with both lenses exposed, the image should

     be perfectly clear. Make minor tweaks if necessary,  
     and remember these settings for the future.

Your Zhumell binoculars have both a main focus 
and a diopter focus, which allows for greater 
control over your view. To bring your binoculars 
into focus, follow these steps:
