Headphone Jack
Volume Control
This BOOKMAN is equipped with several special features that many, but not all,
BOOKMAN books can use. To learn if you can use the special features with a particular
BOOKMAN book, read its User’s Guide.
Headphone Jack:
The headphone jack is designed for 3.5 mm, 35 ohm impedance
stereo headphones.
Caution:
Monophonic headphones will not work with this
BOOKMAN.
Volume Control
: The dial controls the volume of the speaker or headphones.
Speaker:
The speaker is located next to the screen. For best results, do not cover the
speaker with your hand.
Backlight:
Your BOOKMAN has a backlight to illuminate the screen at night and in other
low-light conditions. To turn on the backlight, first turn on your BOOKMAN and then press
. The backlight will turn off after 30 seconds of non-use. It will also turn off while the unit
pronounces words, but will resume automatically. To turn off the backlight sooner, press
again.
Caution:
The backlight uses a significant amount of battery power. To extend
the life of your batteries, use the backlight only when needed.
