The GSH822 Blood Pressure Monitor is intended for use in the electromagnetic

environment specified below. The customer or the user of the GSH822 Blood

Pressure Monitor should assure that it is used in such an environment.

Electromagnetic environment guidance

Portable and mobile RF communications

equipment should be used no closer to

any part of the GSH822 Blood Pressure

Monitor, including cables, than the

recommended separation distance

calculated from the equation applicable to

the frequency of the transmitter.

Recommended separation distance

d=1.2 P

d=1.2 P 80MHz to 800 MHz

d=2.3 P 800MHz to 2.5 GHz

where P is the maximum output power

rating of the transmitter in watts (W)

according to the transmitter manufacturer

and d is the recommended separation

distance in meters (m).

Field strengths from fixed RF transmitters,

as determined by an electromagnetic site

survey , should be less than the

compliance in each frequency range.

Interference may occur in the vicinity of

equipment marked with the following

symbol:

a. Field strengths from fixed transmitters, such as base stations for radio (cellular/

cordless) telephones and land mobile radios, amateur radio, AM and FM radio

broadcast and TV broadcast cannot be predicated theoretically with accuracy.To

assess the electromagnetic environment due to fixed RF transmitters, an electro-

magnetic site survey should be considered.

If the measured field strength in the location in which the GSH822 Blood

Pressure Monitor is used exceeds the applicable RF compliance level above,

the GSH822 Blood Pressure Monitor should be observed to verify normal

operation. If abnormal performance is observed, additobal measures may be

necessary,such as reorienting or relocating the GSH822 Blood Pressure Monitor.

b. Over the freqnency range 150 kHz to 80 MHz, field strengths should be less than

3 V/m.

NOTE 1 : At 80 MHz and 800 MHz, 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.
