It is quite straightfoward to set up this digital body tape measure.

STEP 1: Download the Ejeray Health phone app from either App Store or Google Play and complete the simple user profile setup process.

STEP 2: Open the cover at the back and insert the included battery carefully but firmly. 

Tip: The battery may not settle in the casing easily the first you install the battery. In such cases, place just lower right edge of the battery fully inside the casing and close the cover slowly.

STEP 3: Turn on the device by pressing the power button. Press the M button for 2 seconds or more to toggle between inches and centimeters.

You can track the measurements of 11 body locations with the app. 


Please note that the tape measure does not recognize the body part you are measuring. You need to select the body part you measured by tapping the corresponding body part on the phone app before sending the measurement data.

One tape measure can be used to track the measurements of more than one person. You can do this by creating multiple profiles inside the phone app. Alternatively, each person can download the app into their mobile phone and tracking their own data individually. 


Once you create your user profile and input data, the app will also show your BMI (body mass index), wasit-to-hip ratio and body shape.

For more information about the app, please refer to the included user's manual.
