1-4 Safety Information
For your safety please strictly comply with the following precautions. Failure to comply may
cause safety problem or device failure.
Do not illuminate the light more than required to observe the fundus of
patient’s eye. It may damage the patient’s eye.
Do not use together with parts other than standard accessories
including in this package. Problems or damage may occur.
Do not apply a strongly impact. It may cause injury or device failure.
Do not turn the illumination on when covered with the plastic bag and
the like. It may cause the inside high temperature and result in injury,
device failure or fire.
Do not touch the bulb with bare hands immediately after turned off
since it is still hot. It may result in injury.
Do not
impact to the device during the bulb is lighted or immediately
after turning the bulb off. It may cause breakage of bulb filament.
Do not operate in direct sunlight or harmful light. Doing so may create
high heat or damage of the device.
Do not use in extremely humid place orcome in contact with salt water,
or allow water to come in contact with the device. It may cause device
failure.
Do not sterilize the device. It may cause deformation or device failure.
Do not use thinner, cleaning agents, or boiled water to clean the
device. It may cause deformation or device failure.
Do not insert any foreign materials
into the gaps of device. It may
cause device failure.

4
Be sure to use original Carrying
case during movement or
transportation. Doing so may protect against deformation or device
failure.
Be sure to use genuine battery without fail. Not doing so may cause
device failure.
Remove the battery when the device will not be used for long periods
of time to prevent from electrolyte leakage.
Do not attempt to disassemble or modify the device. Doing so may
result in electrical shock, fire or device failure.
Do not touch the device with wet hands. Doing so may cause device
failure.

3. Operation
3-1 Charging RX-RC
Charge the RX-RC with the optional Dual Desk Charger RC-II (hereinafter, called as
“RC-II”) sold separately.
RX-RC
It is available to charge 2 sets of the RX-RC
simultaneously
ME System
Charging Ports
RC-II (Non-medical device)
Insert the Handle of RX-RC into the charging port of RC-II, which is exactly connected
to theAC power through theAC adaptor, until it stops as shown in the above figure. Be
sure to turn the RX-RC off during charging.
Full charging of battery is completed after approx. 15 hours from an uncharged
condition.
When fully charged the RX-RC can be illuminated for approximately 80 minutes at the
maximum amount of light.
Read the instruction manual for RC-II
Be sure to charge the RX-RC after turning it off. If still ON, it
may create high heat felt hot in touch as well as charging is
unable.

3-2 Turning Illumination ON/OFF
While pressing the Switch button on the Handle,
rotate the Switch ring to the left (towards ON) to
turn the power and light on. (Fig. 3-1)
Since the light adjustment function is built in the
RX-RC, the further the Switch ring is rotated to the
left (towards ON), the brighter the light becomes.
To turn the light off, rotate the Switch button to the
right until it completely returns to the OFF position.
3-3 Varying and Rotating Streak
By shifting the Streak varying lever upward anddownward based on the reference line,
it is available to vary the streak as follows. The reference point on the Streak varying
lever is the top of it.
(1) Upper position than the reference line: Convergent ray (Fig. 3-2a)
(2) On the reference line: Parallel ray (Fig.3-2b)
(3) Lower position than the reference line: Divergent ray (Fig. 3-2c)
In addition, the streak can be rotated 360 degrees with no limit by turning the Streak
rotation ring (see Fig. 3-3).
3-4 Screening
(1) Turn the RX-RC on and shift the Streak varying lever fully downward to observe
the divergent ray.
When the divergent ray is used, follow the procedure below.
