11.1. Battery installation
There is a sliding battery door located on the back of the Ultrasonic Sound
Generator.
Turn the unit over so that the controls are facing the floor, and the sensor is
facing away form your body.
At the opposite end from the sensors (the end closest to you) there is a
sliding panel.
Apply minimal pressure to the center of the panel and slide it towards you
exposing the battery compartment.
Install a new 9 volt battery noting the (+) and (-) positions which are indi-
cated on the inner label.
If you plan to store the instrument for an extended period of time, remove
the battery.
12. Care and maintenance
The Ultrasonic Sound Generator can be cleaned with a towel using dish
soap and damp cloth. Remove the batteries and close the door before
cleaning. Do not allow water to enter the unit, especially the front where the
sensor is located. After cleaning, dry the units with a paper towel. The
same procedure can be used on the carrying case.
13. Headset
To use the system, plug the headphone into the jack located on the right
side of the instrument. The loudness can be controlled by a sensitivity ad-
justment which is integrated in the cable.
