11.3 Determine the function of the basic performance
This product is used for the measurement of the length of apical teeth.
11.4 The equipment is not provided for use only in the shielding place, for
the non life support equipment
Recommended separation distance between Portable and mobile RF communications
equipment and apex locator
The apex locator is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the apex locator can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF 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 meters (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.
NOTE 1
: At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2
: These guidelines may not apply in at I situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
