Warning:
1. The device should not be used adjacent to or stacked with other equipment. If adjacent or stacked
use is necessary, the device should be observed to verify normal operation in the configuration in
which it will be used.
2.Use of accessories, transducers and cables other than those specified or provided by the
manufacturer of this equipment could result in increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment and result in improper operation.
3. Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the CPAP, including cables
specified by the manufacturer. Otherwise, degradation of the performance of this equipment could
result.
