Welch Allyn Propaq LT Vital Signs Monitor

Recommended separation distances between portable and mobile RF communications equipment

and the battery-operated Propaq LT Series monitor

The battery-operated Propaq LT Series monitor is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the battery-operated Propaq LT Series monitor can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the battery-operated Propaq LT Series monitor 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.
