For transmitters rated at a maximum output power not listed above, the
recommended separationdistance d in meters (m)can be estimated using the
equation applicable to the frequency of thetransmitter, where P is the maximum
output power rating of the transmitter in watts(W)accordableto the transmitter
manufacturerNOTE I At 80 MHZ and 800 MHZ. the separation distance for the
higher frequency range appliesNOTE 2 These guidelines may not apply in all
situations. Electromagnetic propagation is affected byabsorption and reflection from
structures, objects and people.
Recommended separation distances between portable and mobile RF
communications equipment and the model.
Apex locator in the above specified electromagnetic environment, it will be safe, and
it can provide the basic properties such as article 1.6.1-1.6.3;
1. Measurement of pulpitis, pulp necrosis, periapical periodontitis and tooth length.
2. Measurement of the tooth length before restoration of post crown.
3. Measurement of the tooth length of transplantation and retransplantation.
