3）Determine the function of the basic performance
This product is used for the measurement of the length of apical teeth.
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.
