Volume
Pressing
the
Volume Up
or
Volume Down
button adjusts the audio volume. Each press
of the control will make one adjustment. There is a total of 45 dB of volume control in 15
steps. Each step is either three or four dB. The lowest volume setting will not mute the
audio output.
A distinct double beep sounds when the volume is adjusted to the maximum or minimum
to inform the user that no more adjustment is available.

If the volume is adjusted to the lowest setting when the machine is powered off, it will be
reset at a slightly higher level when the player is subsequently turned on. This is done to
ensure that the user can hear the player power up.
Sleep
Sleep
Primary
Pressing
the
Sleep
button starts both playback and a timer that will turn the player off
after 15 minutes. If the button is pressed again, within 5 seconds, the sleep timer is
increased in 15 minute steps up to 1 hour. When the timer expires the audio will fade out
over 5 seconds and playback will stop.
Pressing the
Play/Stop
button while the sleep timer is active will disable the sleep
function. Pressing any other controls, such as volume, will have no effect on the sleep
timer.
Secondary
The player’s
serial number
and
software version
can be played by rapidly pressing the
Sleep
button 10 times or more when a cartridge is not inserted. The informational
message will repeat until the
Play/Stop
or
Power
button is pressed.
Tone
Tone
Pressing
the
Tone Up
or
Tone Down
buttons adjusts the tonal quality of the player
audio. The treble (high frequencies) can be boosted by up to 10 dB with the
tone up
control, and the bass (low frequencies) can be accentuated by the same amount with the
tone down
control (compared to the mid setting, which is flat). At the extreme
Tone Up
setting, there is a 10 dB boost in treble and a 10 dB cut in bass. An analogous effect
occurs at the extreme
Tone Down
setting.
A distinct double beep sounds when the tone is adjusted to maximum or minimum to
inform the user no more adjustment is available. A different beep and announcement
sound at the neutral tone setting.
The tone adjustment is only active when a book cartridge is inserted. When a book
cartridge is inserted for the first time, the player sets the tone level to neutral. The player
remembers the setting for each book so that the tone setting for that book is recalled when
the book cartridge is reinserted.
