User Operation and Controls Section 2
Power
Power
Primary
Pressing the Power button turns the player on and off when it is being powered from the
battery. When the player is powered by AC, the Power button enables and disables the
keypad and USB ports, but part of the circuit is always powered (battery
monitoring/charging).
The player turns on automatically when AC power is applied.
Secondary
Pressing and holding the Power button for 7 seconds will apply a hardware reset to the
microprocessor. This should be necessary only when the player has become unresponsive
to other controls. Resetting the player does not erase any stored data or bookmarks.
Key Describer
If the player has no cartridge inserted, pressing the Power button plays an informative
message describing the use of the Power control and the remaining battery capacity.
Pressing the Power button again during this message or shortly thereafter turns the player
off.
Volume
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.
