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 acclimatize for a short period of
time before storing so that residual
moisture can dissipate.
