How can I charge my COOL-ER?
Connect your COOL-ER to a computer via the USB
cable and your COOL-ER will immediately begin to
charge while the computer is powered on. Your
COOL-ER will charge each time it is connected for
file transfers and even charge while transferring
documents. Your COOL-ER will be shipped with a
slight charge but to charge it completely from fully
empty takes a couple of hours. A full charge
should last for about 8000 button clicks.
How long will my COOL-ER’s battery last
between charges?
COOL-ER only requires battery power when
responding to button clicks or running the audio
function, so users can run it for weeks without
charging the battery. A single charge can last for
8,000 button clicks, which is equivalent to reading
an average novel fifteen times over!
How do I change the text size on my
COOL-ER?
Open a book on your COOL-ER and click the centre
button of the control wheel. This brings up your
main menu, scroll down to the ‘Font Options’
option and click the centre button again. You can
then scroll through the font sizes. Select your
favourite font size using the up/down buttons on
the scroll wheel, and then click the central button.
Your chosen text size will be applied throughout
the document and you’ll be returned to the ebook
to continue reading.
How do I select a book to read from the
library?
In the library scroll up and down using the
control wheel and, once you’ve chosen a
document to read, click the central button in
the control wheel. Your ebook will then load.
(The time taken to load is dependent on the file
size. Larger texts will take longer to load as
your chosen formatting is applied to the full
document at this time.)
How do I attach the USB cable?
While your COOL-ER is turned on connect the
smaller end of the USB cable to your COOL-ER
via the port on the bottom edge (next to the
headphone jack). Then connect the larger end
to your computer’s USB port. Your COOL-ER
should then be automatically recognised and
you can begin transferring files.
How do I turn on my COOL-ER?
Press and hold down the oval button positioned
next to the memory card slot on the top edge of
your COOL-ER for a moment. The green LED
will show on the upper right face of the COOL-
ER and you’ll see a display of your COOL-ER’s
greyscale on the screen. When the COOL-ER
has finished loading the greyscale image will
disappear and your COOL-ER take you directly
to the library page.
How can I turn my COOL-ER off?
You can switch off your COOL-ER by holding
down the on/off button on the top edge next to
the memory card slot.
