Recommended separation distances between portable and mobile RF communications equipment and the Therma
The therma is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the Therma can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Therma as recommended below, according to the maximum output power of the communications equipment.

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.
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Acceptable Compliance Criteria
The following shall be degradation of performance that does not affect essential performance or basic safety:
- interruption of output power or reset into standby mode when clearly indicated on the operational panel of Therma..
