b. Recommended separation distance
The device is intended for use in a electromagnetic environment in which RF radiation disturbances are
controlled.
The user or installer of the device can help avoid electromagnetic interference by maintaining a minimum
distance, depending on the maximum power of the radio frequency transmission equipment. Portable RF
communications devices (including devices such as antenna cables and external antennas) must not be
used closer than 30 cm (12 inches) to any part of the device, including cables specified by the
manufacturer. Otherwise, the performance of these devices could be affected.
c. Electromagnetic emissions
This product is intended for use in the electromagnetic environment specified below. It is up to the
customer or the user to verify that the instrument is used in this environment.
