About Your Pebble
Congratulations on your purchase of the Pebble
from Enhanced Vision. The Pebble is a handheld
electronic video magnier 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 t in your pocket or purse,
the Pebble is the ideal companion to provide
magnication, on the go.
With the Pebble, you can easily read bank
statements, coupons, prescriptions, restaurant
menus, sign checks - anywhere you need portable
magnication. The Pebble provides hours of low
vision enhancement.
Featuring a built-in, 3 ½” LCD screen, 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 magnication. 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.

This product is intended to be used as a portable•
device. Please use care when connecting/discon-
necting cables and accessories.
Care & Maintenance:
Always turn the power OFF on the Pebble when•
the system is not in use.
To prolong battery life, remove the battery from•
the Pebble if the system is not being used for one
week or more.
If needed, clean the surface of the Pebble with a•
soft damp cloth or an electrostatic dusting wipe.
DO NOT use liquid cleaners on the plastic surfac-
es. No additional methods of sterilization or clean-
ing are recommended or required.
Susceptibility to Interference:
There may be temporary performance degradation
of the Pebble when subjected to a strong magnetic

Power Options
Your Pebble can be powered using:
The included AC adaptor/power supply •
Rechargeable batteries (included)•
When using the Pebble for the rst time,
please power the unit using the included AC Adaptor/
power supply. This will ensure that the rechargeable
batteries can fully charge, even while the Pebble is
in operation. Although regular Alkaline batteries may
work to power the Pebble, the battery life may vary
and will be reduced signicantly compared to using
rechargeable batteries.
Note: Using regular alkaline batteries while
inadvertently plugging in the AC power supply
can damage the unit and WILL void the warranty.
Connecting the AC adaptor/power supply
Use the following procedure to connect the Pebble to
the AC adaptor/power supply:
1) Connect the tip of the included
AC adaptor/power supply to the
DC IN port on the bottom edge of
the Pebble (See Figure 1).
2) Plug in the remaining end of the
AC adaptor/power supply to an
available AC wall outlet (mains)
(See Figure 2).

Using the Pebble
Freezing an Image (Snapshot function)
If desired, you can take a temporary snapshot
(freeze) an image on the display. You can also adjust
the size and color modes after freezing an image.
This feature is quite useful for reading price tags,

capture the image (See Figure 2).
Pebble will sound a short conr-
mation tone (“beep”) when the
image is captured. After capturing
the image, you can adjust the size
or color modes as described pre-
viously on pages 11 & 12.
3) Press the FREEZE button
again (Figure 2) to exit and
resume normal operation of your
Pebble. Turning off the power of

Charging & Using Batteries
Important Points When Using Battery Power
The Pebble should ONLY be used with•
rechargeable batteries.
Rechargeable batteries should be rated at•
2400mAh or greater.
Rechargeable batteries should be fully charged•
prior to rst use.
Using new batteries, your Pebble should last over•
1.5 hours when fully charged. The total usage time
will gradually reduce with subsequent charges.
It is not recommended to use standard “AA”•
batteries (or alkaline) inside the Pebble. Standard
batteries are not capable of being recharged
inside the Pebble charging system and may pose
certain safety risks.
Using Rechargeable Batteries
Your Pebble includes two, rechargeable Nickel-
Metal Hydride (NiMH) batteries that can be
continuously charged inside the Pebble, even
while the unit is in operation (see page 10). It is
recommended to leave the unit connected with the
included AC adaptor when the unit is not in use to
maintain a continuous charge on the batteries. This
way, your Pebble will always be ready for portable
use. It is not possible to overcharge the included
Nickel-Metal Hydride (NiMH) batteries. Please refer
to the instructions on the next few pages for more
information on replacing and charging the batteries.

Charging & Using Batteries
To charge the Nickel-Metal Hydride (NiMH) batteries
inside your Pebble, simply connect the included AC
adaptor/power supply as described on the bottom of
page 10. You can continue to use the Pebble even
while the batteries are being charged.
Your Pebble has two small
indicator lights (LEDs)
located on the side of the unit.
The LEDs indicate the current
power state and charge status
of the batteries (see Figure 1).
Refer to the table below for more information
regarding the meaning of each LED indicator light:

of battery power remaining, Pebble will begin
to sound a series audible short beeps every 30
seconds. When this occurs, please recharge or
replace the batteries soon.
