Recommended separation distance between portable and mobile RF
communications equipment and the MEDICAL SCALE
The MEDICAL SCALE MS4971 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the MEDICAL SCALE MS4971 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MEDICAL SCALE
MS4971 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 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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.

Click OK button to complete the setting. The PC will retrieve the
weighing & BMI data from the CHARDER scale and display on the
HyperTerminal program similar to the layout below.
While the Hyper Terminal program is running, type “P” KEY on the PC
keyboard to transmit a print command to printout from the thermal
printer on the CHARDER scale for hard copy of weighing data & BMI.
Or, press the [PRINT] button on the display panel of CHARDER scales,
the printout presented below is the standard format print layout as
well as shown on the HyperTerminal computer screen.
