Technical Information
This device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. Customers or
users of this device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communication equipment (transmitters) and the device as recommended below, according to maximum output power of the
Rated Maximum Output Power

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.
NOTES:
• At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
• These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects, and people.
