The TH9xyz series is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the TH9xyz series can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the TH9xyz series 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 separation distance for 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.

Floors should be wood, concrete or ceramic tile. If floors are
covered with synthetic material, the relative humidity should be at
least 30 %.

requires continued operation during power mains
interruptions, it is recommended that the TH9xyz series be
powered from an uninterruptible power supply or a battery.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commercial or
hospital environment.
