TELEMETRY TRANSMITTER (96281) OPERATIONS MANUAL A-4
A PPENDIX A — GUIDANCE AND MANUFACTURER’ S DECLARATION
Separation Distances
The 96281 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or user of the 96281 telemetry transmitter can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the 96281 as recommended below,
according to the maximum output power of the communications equipment.
Table 3—Separation Distances
Recommended separation distances between portable and
mobile RF communications and the 96281 telemetry transmitter
Rated maximum output
power of Transmitter (W)
Separation distance according to
the frequency of transmitter (m)
0.01 0.117 0.234
0.1 0.37 0.738
1 1.17 2.34
10 3.69 7.37
100 11.7 23.4
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
Notes:
• At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
• These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
