Determining Eye Distance
The distance between one's eyes varies from person to person, so it is essential that you adjust your
binoculars before you use them. Take the binoculars in both hands (Fig. 1) and hold them to your eyes.
Fold them so that you see a single circle when looking through them (Fig. 2).

Adjusting The Focus

To adjust the focus, simply turn the center focus wheel (Fig. 3).

Cleaning Instructions

To clean the eyepieces and/or objective lenses, only use a soft, lint-free cloth like a microfiber cloth. Do
not apply excess pressure to the cloth to avoid scratching the lenses. To remove more stubborn dirt,
moisten the cleaning cloth with an eyeglass-cleaning solution and wipe the lenses gently being careful
to avoid excess pressure. Protect this device from dust and moisture. When using in high humidity
conditions, let the device sit for a short period of time before storing so that residual moisture can
dissipate.
