Guidance and manufacturer's declaration – electromagnetic immunity

The Ameda Penguin Warmer is intended for use in the

electromagnetic environment specified below.

These guidelines may not apply in all situations. Electro-

magnetic propagation is affected by absorption and

reflection from structures, objects and people.

Recommended separation distances between portable and mobile

RF communications equipment and the Ameda Penguin Warmer

The Ameda Penguin Warmer is intended for use in an

electromagnetic environment in which radiated RF disturbances

are controlled. The customer or the user of the Ameda Penguin

Warmer can help prevent electromagnetic interference by

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.

electromagnetic site survey should be considered. If the measured

field strength in the location in which the Ameda Penguin Warmer is

used exceeds the applicable RF compliance level above, the Ameda

Penguin Warmer should be observed to verify normal operation. If

abnormal performance is observed, additional measures may be

necessary, such as re-orienting or relocating the Ameda Penguin

Warmer.

Electromagnetic environment – guidance

Portable and mobile RF communications equip-

ment should be used no closer to any part of the

Ameda Penguin Warmer,

including cables, than the recommended

separation distance calculated from the equation

applicable to the frequency of the transmitter.

Recommended separation distance

d = 1,2√P

d = 1,2√P 80 MHz to 800 MHz

d = 2,3√P 800 MHz to 2,7 GHz

Where P is the maximum output power rating

of the transmitter in watts (W) according to the

transmitter manufacturer and d is the recom-

mended separation distance in meters (m).

Field strengths from fixed RF transmitters, as

determined by an electromagnetic site survey,

should be less than the compliance level in each

frequency range.

Interference may occur in the vicinity of equip-

ment marked with the following symbol:
