turning leD lighting on/oFF
Your Pebble has built-in LED lighting to illuminate
your reading material. By default, this lighting will
turn ON automatically whenever the Pebble is
powered on. It is also possible to turn OFF the built-
in LED lighting, if desired. This may be useful when
magnifying certain objects with a highly reflective
surface, such as a glass medicine bottle or glossy
photo. Turning the LED lighting off in these instance
may improve visibility and help to reduce glare. Use
the following procedure to turn off the LED lighting:
Static/Dynamic leD Modes
There are two modes in which the built-in LED
lighting of your Pebble can function, which can be set
according to your own preferences:
1) Static leD Mode:
In “static” mode, the built-in LED lighting of your
Pebble maintains a constant intensity (brightness) to
illuminate your reading material at all times.
2) Dynamic leD Mode:
In “dynamic” mode, the built-in LED lighting of your
Pebble will vary in intensity (brightness) according to
ambient lighting condition and the the contrast of your
reading material.
Note: With “dynamic” LED mode, the lighting will provide
maximum intensity when viewing dark contrasted
surfaces or in low lighting conditions. Conversely, the
brightness of the LED will decrease when viewing
illuminated surfaces or in bright ambient lighting
conditions. Using the “dynamic” LED Light mode will help
to maximize battery life, and may improve image quality
depending on the contrast of your reading materials.
Use the following procedure to change the leD modes:
1) With the Pebble power turned
on, press and HOLD the
[MODE] button for approximately
4 seconds. This will turn off the
LED lighting (see Figure 1).
1) With the Pebble power
turned on, press and HOLD the
[SIZE] button for approximately
4 seconds to toggle between
either “static” or “dynamic” LED
modes (see Figure 1).
2) To restore the LED lighting, either press and
HOLD the [MODE] button again for ~ 4 seconds, or
turn off the power of your Pebble. Each time the
Pebble is powered on, it will automatically default to
the factory setting with the LED lights illuminated.
(see Figure 1).
Note: The selected “Static” or “Dynamic” LED mode will
be retained in memory, even after powering off Pebble
.
