11. SPECIFICATIONS AND PERFORMANCE
REQUIREMENT TO THE EXTERNAL CONNECTION DEVICES
The accessory devices that are connected to the analog and digital interface must comply with
the relevant IEC standard.
(Example: IEC60950-1 for the data processing devices and IEC60601-1 for the medical
devices)
All of configuration must comply with IEC60601-1.
Those who connect the additional device to the signal input/output units should make a medi-
cal system and therefore take total responsibility to obey the requirements of IEC60601-1
about their system. If someone has a question, he/she must contact the TOPCON authorized
dealer or TOPCON office at the address on the back cover.
Recommended separation distance between
portable and mobile RF communications equipment and the CV-5000
The CV-5000 is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of the CV-5000 can help prevent electromag-
netic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the CV-5000 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 recommended separa-
tion 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
NOTE 2
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.
