Portable and mobile radio frequency-based communications equipment must not be used closer to the device, including conductors, than the recommended distance calculated based on the applicable formula for the transmitter's frequency. Recommended distance between devices d = 1.2√P d = 1.2 √P From 80 MHz to 800 MHz d = 2.3√P From 800 MHz to 2.5 GHz, where P is the maximum rated output power for the transmitter in watts (W) as per the manufacturer of the transmitter, and d is the recommended, seperation distance in metres (m). The field strengths from fixed radio frequency transmitters, as measured in an electromagnetic examination of the location, a ought to be lower than the compliance level in each frequency range b. Interference may occur in the area around devices, which is marked with the following symbol:

At 80 MHz and 800 MHz the higher frequency range applies. It is possible that these guidelines do not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from buildings, objects and people. a) Field strengths from fixed transmitters, such as base stations for radiotelephones (mobile/wireless) and land mobile radios, amateur radio equipment, AM and FM radio transmitters and TV broadcasting, cannot be estimated reliably theoretically. Consider performing an electromagnetic field survey in order to assess the electromagnetic environment that is caused by fixed radio frequency transmitters. If the measured field strength at the location where the device is being used exceeds the compliance level for radio frequency energy that will be used, then you should observe the device in order to check that its operation is normal. If abnormal operation is observed, further precautions may be necessary, for example turning or relocating the device. b) Over the frequency range from 150 kHz to 80 MHz the field strength should be less than 3 V/m.

The model RS electronic digital scale is intended for use in the electromagnetic environments as specified below. The customer or the user must ensure that the scale is used in such an enviroment.
