Warning:
Portable RF communications equipment
(including peripherals such as antenna
cablesand external antennas) should be
used no closer than 30 cm(12 inches) to
any part of the tbCOMPASS,including
cables specified by the manufacturer.
Otherwise,degradation of the performance
of this equipment could result.

7. Essential performance
Unless operated by the chair control switch, the chair will not make any movements. Unless operated by the
foot controller, the handpiece will not move except for sounding a buzzer and switching the indicator on/off.
Loss or decline of essential performance may cause the chair or handpiece to move unexpectedly, causing
harm to the patient, operator or people or objects around the patient or operator.
