Zeiss 3000 - Accessory Equipment

Recommended separation distances between portable and mobile RF communications equipment
and the Stratus OCT
The Stratus OCT is intended for use in an electromagnetic envir
onment in which radiated RF disturbances are
controlled. The customer or the user of the Stratus OCT can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the Stratus OCT as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the r
ecommended separation distance d in
metres (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 higher frequency applies.
Note 2: These guidelines may not apply in all situations. Electr
omagnetic propagation is affected by absorption
and reflection from structures, objects and people.

Accessory Equipment
WARNING: Accessory equipment connected to the analog and digital
interfaces must be certified according to the respective IEC standards (e.g.,
IEC 60950 for data processing equipment and IEC 60601-1 for medical
equipment). Furthermore, all configurations shall comply with the system
s t a n d a rd I E C 6 0 6 01-1-1. A n y p e r s o n w h o connects additional equipment to
the signal input part or signal output part configures a medical system, and is
therefore responsible for ensuring that the system complies with the
requirements of the system standard IEC 60601-1-1. If in doubt, consult the
technical service department or your local representative.
