during power mains interruptions, it is recommended that the
TMS-51A be powered from an uninterruptible power supply or a

Recommended separation distances between
portable and mobile RF communications equipment and the ME EQUIPMENT or ME SYSTEM
The TMS-51A is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
TMS-51A can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the TMS-51A 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.
