b) The carrier shall be modulated using a 50% duty cycle square wave signal.
c) As an alternative FM modulation, 50% pulse modulation at 18 Hz may be used because while
it does not represent actual modulation, it would be worst case.
Recommended separation distances between portable and mobile RF communications
equipment and the EQUIPMENT or SYSTEM
Recommended separation distances between
portable and mobile RF communications equipment and Holter System Recorder
Holter System Recorder is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of Holter System Recorder can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and Holter System Recorder 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.
