Precautions for Operations
You must observe the following instructions. Nikon is not responsible for the impaired safety or
reliability of this product due to your failure to follow the correct operating procedure.
(a) Do not set this instrument up other than as specified in this manual.
(b) Nobody other than Nikon-qualified sales or service personel should adjust or repair this instrument.
(c) Use this instrument only according to the instructions specified in this manual. Do not perform any
operations which is not described.
(1) Safety Precautions _
1) Never disassemble this instrument (which contains hazardous high-voltage parts which
can cause injury).
2) Do not drop the Retinomax. Use the accompanying strap when handling the measuring
unit and printer. Do not drop on the Retinomax.
3) Take precaution that the measuring unit does not
bump against the patient's face (when moving it
toward the patient or in the right or left direction).
(2) Environmental Requirements
1) The best environment for operation is between approximately 10-30* C room temperature,
and 70% or less humidity.
2} The Retinomax is not waterproof and therefore must not be placed in an environment
where water (such as rainwater) may come in contact with the unit.
3) When dew forms on the instrument, do not use it until the dew evaporates.
4) The Retinomax is reasonably dustproof, but use it away from dust.
5) Put on the place where air the station and printer. And do not put a thick cloth or paper
under the station and printer, because there raditate heat, in the charging case.
6) The best place for operation is in a dimly lit room.
The measuring window should not be subject to
bright, brightly light, because the measuring
accuracy may be reduced.
3

3) Handling Precautions _
1) Do not hold any part other than the grips of the measuring unit (such as the view finder or
forehead rest).
2) Handle the measuring unit with caution.
3) Do not unnecessarily swing the measuring unit.
4) Do not touch the contact points of the connectors or the charging terminals with your hand or
metal. If the contact points are stained, became farhshed turn the power switch off and wipe
them with dry and a soft cloth.
5) Do not place the measuring unit or the printer near any magnetic object.
6) Hold the plug when disconnecting the power cable or the optional communication cable
from the outlet or connector to not break or damage the cable.
7) Use only the Nikon-designated battery pack and optional AC adapter.
8) Never short-circuit the terninals the charging of the charging case. If you short-circuit the
teminal will blow the fuses.
4) Maintenance _
1) The measuring unit is a precision optical
instrument. If the measuring window glass is
smudged with grease from the patient's nose,
finger prints or dust, accurate measured values
will not be obtainable. Keep the measuring
window glass clean.
When you clean the glass, be careful not to scratch
or break it (see "(4) Cleaning the measuring window” in page 44).
2) After operation, turn the power switch off and cover the instrument with the vinyl cover
provided.
4

(5) Pre Cautions for the Battery Pack _
1) Use only the DURACELL nickel-hydrogen battery DR10 (manufactured by Duracell).
Nikon will not assure proper operation if you use any other type of battery pack.
2) Never disassemble the battery pack.
3) Never short-circuit the battery pack terminal, because you may get burned by the
generated heat. Take recaution so that any metal (such as a coin and clip) does not touch the
terminal.
4) Charge the battery pack with the specified printer or station (if the battery pack is installed
in the measuring unit).
5) Do not expose the battery pack to any source of excessive heat or flames, because it may
explode, leak or cause a fire.
6) Do not leave the battery pack in an excessively hot place (such as inside a car).
7) Not using the measuring unit or printer, remove battery.
8) If the metal terminal of the battery pack is tarnished, wipe it with a dry and soft cloth.
9) Do not jar or drop the battery pack.

E] 4. Preparation
(1) Attach the strap to the measuring unit.
(see Figure 4-1)
(2) Connect the power cable to the power cable
receptacle located on the station.
(3) Make sure that the station power switch is set to
OFF, and plug the power cable into a wall outlet
(AC100 V).
(4) Turn the stations power switch on.
The power lamp will illuminate.
(5) I nstall the battery pack in the measuring unit.
— See "5. Charging the Battery Pack"
(Figures 5-1,5-2 and 5-3 in page 15).
(6) C harge the battery about 90 minutes by placing
the measuring unit on the station.
See "5. Charging the Battery Pack"
(page 16).
* A new battery pack is fully discharged and must
be charged about 90 minutes before initial use.
** When a new battery pack is installed or after the
unit has not been for a long time, it will require
the battery to charged/discharged a few times in
order to permit the battery to hold a proper
charge for use.
When you charge your battery for the first
time you may get an indication of charging
complete after just 10 to 15 minutes. This is
normal and can happen with all rechargeable
batteries when first charged.
i
Push the CHARGE key. If the CHARGE lamp is
not illuminate, repeat the pushing the CHARGE
key.
(7) Install the print on paper roll.
See "8, Maintenance" (page 41).
(8) Connect the printer with the station.
(see Figure 5-10 in page 18)
(9) Turn the printer power switch on.
* When the printer is connected with the station,
it cannot be used unless the station is ON.
(10) Remove the measuring unit from the station,
and turn the measuring unit on.
Figure 4-2

(11) Complete various settings.
— See "7. Initial Settings (SETUP)" (page 36).
(12) Measure the modelege which was provided
with the unit. Make sure that the model eye
and measuring window are clean. If they are
tarnished, carefully, clean them referring to
sections "(4) Cleaning the measuring window"
and "(5) Model eye" (page 44) in "8.
Maintenance".
® Place the model eye on the model eye
mount on the station (see Figure 4-3).
® Refer "6. Measurement Method" (page 22)
for measuring the model eye .
(D The measured values must be within the
following range;
SPH +4D - +5.5D (CYL is 0)
(CYL. Power should be set to 0 diopters.
Otherwise, the measurment will vary from -
0.25 ~ +0.25 dioptors. This is a normal
variance.)
If the measured value is out of the range,
make sure that the measurement was
correct performed correctly and do the
measurement again (see "6. Measurement
Method" (page 22).
When measuring the model eye, keep it in a
stable position (for example, place your
elbow on the table) to accurately use the
measuring unit.
(13) Clean the forehead rest by using ethyl alcohol or other cleaning liquid.

the battery and starts charging automatically.
When the charging is started, the
CHARGE lamp for the measuring unit is
illuminated.
However, when the battery capacity is
50% or more . it will not be charged and
the CHARGE lamp remains off to ensure
a long life of the battery pack. When the
battery capacity is less than 50%, it will be
charged to the maximum capacity
(charging requires about 90 minutes).
Automatic charging is performed. Figure 5-6
When charging is complete, the CHARGE lamp for the measuring unit goes off.
The charger will turn on automatically when the battery has less than half a charge. If the
battery is at more than 50% of its charge and you would like to charge it futher, you must
press the charge, button again.
* This value will change when the battery life has decreased its capacity according to the
number of charge/discharge cycles.
Note: The Pattery is not always full charge. To make it full charge^ use the CHARGE dr

(2) Automatic charging of the printer battery pack
The printer can be operated with an optional battery pack (of the same type is used for th
measuring unit). It is located and installed in the printer battery box. The battery charge i:
performed in the printers battery box.
Remark: No battery pack is provided for the printer. You must purchase an additions
battery pack for battery operation. The printers battery pack is the same type usee
for the measuring unit.
1) Replacing the battery pack
Place the printing unit on its side. Then slide
the battery release button upward to pop the
battery outward for removal.
Figure 5-7
Remove the battery pack and install the new
one as shown in the figure 5^. Ensuring
the correct orientation of the battery pack,
first slide the side of the battery pack (1) into
the battery box and then push down the
side (2) until it clicks shot.
