dealer or the agent who/where you purchase this instrument.
When there is smoke, strange odor or abnormal sound.
When liquid has been spilled into the instrument or a metal
object has entered through an opening.
When the product has been dropped or its housing damaged.
CAUTION
This instrument is shipped with a grounding type power cable. To
reduce the risk of electric shock, always plug the cable into a
grounded power outlet.
CAUTION
Wipe the forehead rest with ethanol or glutaraldehyde solution to
disinfect it each time a different examinee uses it, in order to
prevent infection.
CAUTION
Do not use the device near, on, or under other electronic equipment
to avoid electromagnetic interference with the operation of the
device.
CAUTION
Do not use the device in the same room with other equipment such
as life-support equipment, other equipment that has major affects
on the life of patient an results of treatment , or other measurement
or treatment equipment that involve small electric current.
CAUTION
Do not use the device simultaneously with portable and mobile
radio frequency communication systems because it may have an
adverse effect on operation of the device.
CAUTION
Do not use cables and accessories that are not specified for the
device because that may increase the emission of electromagnetic

1 BEFORE USE
1.1 Outline of the Refractor
The RODENSTOCK REFRACTOR Model Phoromat 2000 is a computerized refractor
used for subjective refraction with the connected RODENSTOCK AUTO
REF/KERATOMETER, LENSMETER, CHART PROJECTOR.
The Phoromat 2000 includes a refractor head, control box, junction box.
The control box includes the key panel and display. The display is touch-screen panel.
The control box allows the data to be displayed and almost all operations to be
performed. In addition, the control box operates the refractor head and also connected
chart presenting device. It allows the refractor and charts to be controlled together.
1.2 Indications for Use
Instrument providing means of positioning spherical and cylindrical lenses, prisms and
other optical devices in front of a subject's eyes for purpose of determining refractive
error and binocular functions.
In this operator's manual, the keys on the control box are indicated by key representa-
tions like [Shift] or
The touch buttons on the touch panel other than chart buttons are indicated by
brackets like [LAMP].
The touch panel chart buttons are indicated by button representations like
