Congratulations on your purchase of the Pebble
from Enhanced Vision. The Pebble is a handheld
electronic video magnifier that you can take
anywhere. Weighing less than 8 ounces, Pebble
features a uniquely-designed folding handle and
includes both near-viewing and table reading
modes. Small enough to fit in your pocket or purse,
the Pebble is the ideal companion to provide
magnification, on the go.

With the Pebble, you can easily read bank
statements, coupons, prescriptions, restaurant
menus, sign checks - anywhere you need portable
magnification. The pebble provides hours of low
vision enhancement.

Featuring a built-in, LCD screen (3.5” or 4.3”), the
Pebble allows you to magnify images up to 10
times. A built in Freeze-Frame feature allows you to
capture any still image and adjust magnification. Six
different viewing modes allow you to choose
alternate color combinations based on your
personal preference.

The Pebble includes a convenient carrying case, a
built-in wriststrap, rechargeable batteries and has
an integrated battery charger. Pebble comes with a

2 year warranty.
