performed, the denomination of the bill is announced when both buttons
are released. The unit turns itself off automatically after completion of bill
identification or a volume or mode change.
3.2 Canceling the current identification cycle
Once the identification cycle has begun, you may wish to cancel the
current cycle and restart it due to several reasons, for instance, realizing
that the bill was not properly inserted, or if the identification is taking long
due to poor condition of the bill. The bill can simply be re-inserted and
identification re-started by pressing one of the buttons.
Upon pressing the button, the unit indicates the start of identification just
as in the case of normal turn-on, by providing a beep or vibration pulse.
3.3 Changing the Output Mode and Volume Level
The unit provides three output modes: Speech, Tone and Vibration.
Three volume levels are available in the Speech output mode. The
modes and volume levels are selected by using both push-buttons
together. The loudness of the tones in tone mode is fixed and cannot be
increased or decreased. It will decrease at low battery levels
automatically to extend the life of the battery.
Pressing and holding any one button, and then pressing and releasing the
other button changes the volume or mode. Each time the second button
is pressed and released, the Output Mode setting cycles between Speech
Mode volume levels 1, 2, 3, Vibration Mode and Tone Mode, and then
back to Speech Mode volume level 1.
A tone of appropriate volume is emitted at each volume setting to indicate
the level chosen. For the Tone Mode, a double-tone of different pitch is
emitted. For the vibration setting, a short vibration pulse is emitted.
The Output Mode and volume level can be changed at any time while the
device is turned on, even while the unit is in the identification process. The
unit continues the identification process upon completion of the mode or
volume change.
If either one of the buttons continues to remain pressed after the mode or
volume change, the unit will wait until it is released before continuing
operation and announcing the denomination.
