GETTING STARTED
Basic use
You need to insert the battery into
the device to turn it on. Take one
battery of the two included in the
package, and carefully remove the
transparencies. Unscrew the Battery
Cover of the device. Insert the
battery minding the polarity. Make
sure that the "+" and "-" signs of the
battery and the device match. Swivel
the Battery Cover back to the device.
NOTE: Inserting the battery
incorrectly will not damage the
device, but it will not work.
Press the Top Cap of the device firmly against the
neck and then press the Start Button. The device
will start to emit sound. This allows the proper
function of the product.
