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 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 SA series device
The SA series device is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the SA series device can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the SA series device as recommended
below, according to the maximum output power of the communications equipment.

(W)
Separation distance according to frequency of transmitter (m)
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (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.
