use of continuous spraying can increase the possi-
bility of vaginal mucosa drying and potential reduc-
tion in desirable microbial organisms.
Although these studies have not been validated,
please consult your healthcare provider for con-
cerns regarding whether these circumstances may

offvalve.
When the ambient temperature is likely to drop to
32 °F (0 °C) or lower, prevent damage to the pipes
and hoses due to freezing.
Frozen water pipes could cause the top unit and the
pipes to break, resulting in a water leak.
Regulate the room temperature to prevent the pipes
and hoses from freezing during cold months.
When not using the product for a long time, close
the shutoffvalve, drain the water from the top unit
and water supply hose, and then turn the power
OFF.*2
When using the product again, allow the product to

inflammation or other problems. (
 Refer to Page 58
for instructions on replenishing the water.)
Leaving the power on may cause fire or heat.
When installing the drain plug with water supply
filter, make sure that it is securely tightened in its
proper position.
Failure to securely tighten it may cause a water leak.
If the bowl is clogged, turn the power OFF*2 and
remove the clog.
If the auto flush were allowed to function, it would
make the wastewater in the bowl unit overflow and
may result in water damage.
Use commercially available tools that are made for
unclogging the bowl unit to remove the clogging.
Make sure of the plus and minus signs on the bat-
teries before inserting them.
Remove depleted batteries immediately.
When replacing the batteries:
Replace both batteries with new ones.
Use the same brand for both new batteries (any
brand available).
Failure to do so may cause the batteries to leak fluid,
generate heat, rupture, or ignite.
When the product is supposed not to be used for
long time, remove the batteries from the remote
control.
Failure to do so may cause the batteries to leak fluid.

SAVE THESE INSTRUCTIONS
About the built-in body sensor
The body sensor detects human movement.
The toilet lid opening or "Auto bowl CLEAN" operation
may be triggered by someone outside the bathroom as
the sensor detects human movement through the door
or wall in front of the top unit.
The sensor may not detect properly depending on the
bathroom layout, resulting in the toilet lid not opening
automatically.
For someone small such as a child, the body sensor
may not detect properly, resulting in the toilet lid not
opening automatically.
When you are using the toilet in standing position, the
length of time it takes for "Auto flushing" to complete or
for the toilet lid or seat to close automatically depends
on the bathroom layout, etc.
About the Flush button
The toilet can be flushed when this button is pushed.
Push the FLUSH button with your finger directly on the
button.
Water droplets collecting on the FLUSH button may
cause the top unit to malfunction. Be sure to wipe off
any water droplets on the button.
About the built-in seat sensor
When you sit on the toilet seat, the seat sensor turns
ON, enabling you to use various features.
(The deodorizer starts when the seat sensor makes a
detection.)
A label indicating the position of the seat sensor is
attached to the seat.
Detection by the sensor may be difficult when the toilet
is used by someone small, such as a child, depending
on how the person sits.
Sit on the seat with the label as a guide. (The label can
be peeled off).
Sit down so that the seat sensor touches your skin
directly.
The seat sensor may not detect properly if there is a
seat cover or clothing. If you use the booster seat for
infants, the seat sensor may not detect properly, result-
ing in the toilet lid closing automatically during use.
Turn "Auto open / close" OFF before use.
Water droplets collecting on the seat sensor may cause
the top unit to malfunction. Be sure to wipe offany
water droplets on the sensor.

Doing so may cause changes in color, irregular heated
seat temperature or remote control malfunction.
It may also cause product malfunction due to the
change in temperature.
Use radios, etc. away from the product.
The product could cause interference with the radio
signal.
If you use a booster seat for infants or a soft
highchair, remove it after use.

What is meant by "EWATER+" ?
"EWATER+" helps the self-cleaning wand feature work
effectively and by preventing the accumulation of dirt
that can cause stains.
"EWATER+" is generated from chemicals already
present in potable water.
"EWATER+" helps to minimize dirty surfaces, but
does not make cleaning unnecessary.

The effect of rinsing with "EWATER+" can vary depending
on the frequency of toilet use and other conditions.
Operation under the default settings is described
in "Mechanism of Auto Functions".
These mechanisms be changed.
