a) For some services, only the uplink frequencies are included
b) The carrier shall be modulated using a 50 % duty cycle square wave signal.
c) As an alternative to 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 com-
munication the equipment
The Handheld Pulse Oximeter is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer
or the user of The Handheld Pulse Oximeter can help prevent electromagne-
tic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Handheld Pulse
Oximeter 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 in metres (m) can be determined 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.
