Sound Switch Pro
Operation
•
Firstly, If the ‘mains plug pack’ is not used check that the unit contains batteries (2 x AA) and that they are
installed with the correct polarity (
If not, see
Changing the Batteries
)
•
Position the Sound Switch Pro as close as practical to the user
•
If this is not possible, plug an extension microphone into the 3.5mm microphone jack and position the
microphone close to the user
(Plugging in an external microphone will disable the internal microphone)
•
Turn the unit on with the
On / Off
switch
•
Initially set the
Sensitivity
adjustment to the maximum (clockwise)
•
Initially set the required sound length to the minimum by pressing the
Delay
button, holding it until the
beeper sounds and then quickly releasing it. This setting will trigger the device as soon as the sound level
exceeds the trigger level.
•
Turn the
Sensitivity
back (anti-clockwise) to the point where the LED lights red reliably with the user's
voice but is
not triggered by background noise
•
To set the sound length needed to activate the switch press and hold the
Delay
button, holding it until the
beeper sounds and then further holding it for the desired delay.
•
Pressing the
Delay
button and releasing it as soon as the beeper sounds will program the Sound Switch
Pro such that
short sounds
(normal conversation) will activate the switch
•
Pressing the
Delay
button and holding it for a while as the beeper sounds will program the Sound Switch
Pro such that a
longer continuous sound
will activate it. The maximum delay is about 12 seconds.
•
Connect the switch output lead to the toy or equipment to be used, adjust the
Sensitivity
and
Delay
to
ensure desired operation
•
Note that it is very important to adjust the Sensitivity and Delay so that the Sound Switch Pro is
not inadvertently operated
by extraneous noises in the room
•
When using the Sound Switch Pro with noisy equipment, remember to keep a reasonable
distance between the Sound Switch Pro and the equipment.
Otherwise the switch may be 'locked on' by the sound from the equipment
•
An external push button switch may be connected to the
Input socket
, to directly trigger the output. The
output will operate continuously while the button is pressed, and extend the output for the same length as
the output setting described below.
Output Settings
In
most
cases it is
not
necessary to change the output settings.
Output settings change the length of time that the output remains active after it is triggered.
•
Turn the unit off with the
On / Off
switch.
•
Hold the
Delay
button.
•
Turn the unit on with the
On / Off
switch
•
Keep holding the
Delay
button until the beeper sounds.
•
Hold the
Delay
button for the length of time that the output will remain active (the beeper is still
sounding), then release it. The maximum time is 16 seconds
