Operator’s Manual  ZM-520PA/521PA/530PA/531PA

The ZM-520PA/530PA is intended for use in an electromagnetic environment in which radiated 
RF disturbances are controlled. The customer or the user of the ZM-520PA/530PA can help 
prevent electromagnetic interference by maintaining a minimum distance between portable and 
mobile RF communications equipment (transmitters) and the ZM-520PA/530PA as recommended 
below, according to the maximum output power of the communications equipment.

150 kHz to 80 MHz
d = 1.2 P

80 MHz to 800 MHz
d = 1.2 P

(For respiration:
d = 3.5 P)

800 MHz to 2.5 GHz
d = 2.3 P

(For respiration:
d = 7.0 P)

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. 

(* For respiration)

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.

The transmitter returns to the normal operating mode within 10 seconds after defibrillation. The 
stored settings are not affected.

The ZM-520PA/530PA bedside monitor is tested to comply with IEC 60601-1-2: 2001 with the 
following composition.
