Recommended separation distances between portable and mobile RF communications equipment
and the Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display Interface
The Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display Interface is intended for use
in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display Interface can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display
Interface 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.
