22 Technical Information
RF Operating Frequencies
Nearby equipment emitting strong magnetic fields can interfere with the PA inductive communication,
even if the other equipment complies with CISPR emission requirements. The operating characteristics of
the PA is as follows:
• Inductive Telemetry
- RF Transmission – Carrier frequency centered at 60 kHz (inductive telemetry). The effective
radiated power is below the limits as specified in EN 302 195.
- RF Reception – Centered at 60 kHZ (inductive telemetry).
2. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be con-
sidered. If the measured field strength of the location in which the PA is used exceeds the applicable RF compliance
level above, the PA should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the PA.
Note
Maintain a reasonable distance between other electronic equipment and the PA.
