Recommended separation distances between portable and mobile RF
communications equipment and the E-CUBE-Plus
The E-CUBE-Plus is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the E-CUBE-Plus can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the E-CUBE-Plus as recommended
below, according to the maximum output power of the communications equipment
Rated maximum output
Power of transmitter
(W)
For transmitters rated at a maximum output power not listed above, the recommended separation distance ‘d’ in meters (m) can
be estimated by 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 higher frequency range applies.
Note 2: These specifications may not be applicable in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and persons.

Description of BASIC SAFETY and ESSENTIAL PERFORMANCE
The E-CUBE-Plus is intended for use in the electromagnetic environment specified above.
The following essential performance of E-CUBE-Plus should be running in such an environment.
1) Frequency of handpiece should be a value between 20 to 30 ㎑.
2) Irrigation volume should be over the 25 ㎖/min during handpiece is operated.
