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 metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey¹,
should be less than the compliance level in each
frequency range.²
Interference may occur in the vicinity of
equipment marked with this symbol.
Note: At 80MHz and 800MHz, the higher frequency range applies. These guide lines may not apply in all situations.
Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
1 Field strengths from fixed transmitters, such as base stations (cellular / cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the Rodenstock Slit Lamp is used
exceeds the applicable RF compliance level above, the Rodenstock Slit Lamp should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orientating or
relocating the Rodenstock Slit Lamp.
2 Over the frequency range 150kHz to 80 MHz, field strengths should be less than 10 V/m.
9.3 RECOMMENDED SAFE DISTANCES
Recommended separation distances between portable and mobile RF
communications equipment and the Rodenstock Slit Lamp
The Rodenstock Slit Lamp is intended for the use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Rodenstock
Slit Lamp can help prevent electromagnetic interference by maintaining a minimum distance
between mobile RF communications equipment (transmitters) and the Rodenstock Slit Lamp
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 din metres (m) can be determined 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: At 80MHz and 800MHz, the separation distance for the higher frequency applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
