Chapter 3 Preparation and Inspection
Before each case, prepare and inspect this instrument as
instructed below. Inspect other equipment that are used with
this instrument as instructed in their respective instruction
manuals. Should the slightest irregularity be suspected, do
not use the instrument and see Chapter 6, “Troubleshooting”.
If the irregularity is still suspected after consulting Chapter 6,
contact Olympus.
Damage or irregularity may compromise patient or user
safety and may result in more-severe equipment damage.
Do not connect the power cord of the MU-1 to a different
voltage electrical outlet. Fire and smoke may result.
According to the “System Chart” in the Appendix, prepare this instrument, other
equipment that are used with this instrument, paper towels, basin, gauze and
protective equipment, such as eye wear, a face mask, moisture-resistant clothing
and chemical-resistant gloves, for the procedure.
Refer to the respective instruction manual for each piece of equipment.
3.1 Preparation of the Equipment
Use 70% ethyl or isopropyl alcohol as directed on the
container’s label. Store 70% ethyl or isopropyl alcohol in an
air-tight container. 70% ethyl or isopropyl alcohol stored in an
open container may cause fires and will lose its efficacy due
to evaporation.
Use basins which are at least 40 cm by 40 cm (16” by 16”) in
size and deep enough to allow the endoscope to be
completely immersed. Do not coil the endoscope’s insertion
tube or universal cord with a diameter less than 40 cm.
The endoscope can be damaged if coiled too tightly.

3.2 Preparation and Inspection of the Maintenance
Unit
Confirm that the Wall Mains Outlet that you connect the
Maintenance Unit to has more capacity than the total power
consumption of all connected equipment (including this
Maintenance Unit). If the capacity is inadequate, fire can
result or the Circuit Breaker may trip and turn OFF the
Maintenance Unit and all other instruments connected to the
same breaker.
• Do not place the Maintenance Unit on its side or upside
down.
• When installing the Maintenance Unit on the hooks, confirm
that the screws which attach the hooks to the wall are not
loose and that the Maintenance Unit is stable when attached
to the hooks . When a hook comes off, the Maintenance Unit
drops and is damaged, and there is a fear that a user hurt by
the Maintenance Unit which dropped.
• The Maintenance Unit’s Ventilation Grills should be clear of
ancillary equipment. Blockage can cause overheating and
equipment damage.
• Do not connect the power cord of the MU-1 to a different
voltage electrical outlet. Fire and smoke may result.

an area where the unit will not be exposed to the water splashed during
operation. When installing the unit using the feet, confirm that the feet stick firmly
to the installation surface, when attaching the unit to the Hook, confirm that the
screws that attach the Hook to the wall are not loose, and that the Hook does not
move when the unit is attached to it (see Figure 3.1).

If Power Fails to Come on
If power fails to come on, inspect the system as follows:
1. Confirm that the Power Cord is connected securely to a Wall Mains Outlet
and the Power Cord Receptacle on the Maintenance Unit.
2. Confirm that the Circuit Breakers have not tripped by checking that the
breaker buttons have not popped up. If the buttons have popped up, reset
the breakers according to the following procedure 3. and 4.
Reset the Circuit Breakers only once. If the power is still not
supplied to the Maintenance Unit after resetting the Circuit
Breakers, immediately turn the Power Switch OFF “ ”
disconnect the Power Cord from a Wall Mains Outlet and
contact Olympus. This condition can result in electrical shock
and/or fire.
When the Circuit Breakers trips, do not reset the Circuit
Breakers immediately. Turn the Power Switch OFF “ ”. Wait
at least 15 seconds before resetting the Circuit Breakers to
prevent Circuit Breaker damage.
3. Turn the Power Switch OFF “ ”, disconnect the Power Cord and depress
the Circuit Breaker buttons until it stops with a click.
