Your unit is equipped with several special features that many, but not all BOOKMAN book cards use. To learn if you can use the special features with a particular book card, 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 unit.
Volume Control: The dial, located under the headphone jack, controls the volume of the speaker or head- phones.
AC Adaptor Jack: The AC/DC adaptor is in the 9 volt range within a current range of 200 to 300 milliamperes.
This symbol indicates that the inner core of the plug of an AC adaptor is negative and that the outer part of the plug is positive. If the symbol on our AC/DC adaptor does not match the above symbol, confirm its compatibility at its place of purchase.
Speaker: The speaker is located on the back of your unit, above the book card slot. For best results, do not cover the speaker with your hand.
