1. Introduction
1.1. Outline of product
HUVITZ HCP-7000 is an automatic chart projector which provides 41 different charts
including red/green and polarized filters for the eye optometry. Users can select the
desired charts instantaneously by cordless remote controller. Charts move quickly and
quietly. The customized two programs will help you to perform more convenient and
effective examination. You can also execute the binocular balance tests, stereo tests,
fixation disparity tests, fusion tests and aniseikonia tests with HCP-7000. This
automatic chart project is compatible with HUVITZ digital refractor, HDR-7000.

propagation is affected by absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the EUT is used exceeds the applicable RF compliance level above, the EUT should be observed to
verifynormal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the EUT. b Over the frequency range 150 kHz to 80 MHz, field strengths
should be less than [V1] V / m.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and

-------------------------------------------------------------------- HCP-7000 Opreator’s Manual 9
The Model HCP-7000 system is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the HCP-7000 system can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the HCP-7000 system 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 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.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies NOTE 2:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
