Range and Function Disclaimer
BLUETOOTH
®
is the name for a short-range radio frequency (RF) technology that operates at 2.4 GHz. The
effective range of most BLUETOOTH mobile devices is 30’ (9.14 m). BLUETOOTH is designed for very low
power use. The compatibility of the BLUETOOTH wireless speaker to mobile/portable devices differs
according to the various individual devices and, in particular, may vary with different software versions for a
device. The normal mobile device BLUETOOTH range can be up to 10 m, however, placement of your
mobile device and the BLUETOOTH wireless speaker’s installation environment will impact your reception
range.
Water and walls can act as blocking agents to the BLUETOOTH signal that your mobile device is using to
broadcast to your BLUETOOTH wireless speaker. Therefore, selecting an installation location that removes
these range blocking obstacles will increase the effective range and performance of your BLUETOOTH
wireless speaker.
You can test your BLUETOOTH reception by performing simple range tests using your mobile device prior
to performing a permanent installation. The best way to make use of the short BLUETOOTH range is to
make sure your BLUETOOTH wireless speaker is as close to the BLUETOOTH transmitter (mobile phone,
Kohler Co. 3 1197249-5-D

Range and Function Disclaimer (cont.)
tablet, etc.) as possible. The less distance between the two devices, the greater will be the reliability of your
BLUETOOTH audio signal, and the less distance means less obstacles in the medium through which the
transmission is passing, so there is a reduced chance of audio signal loss.
The compatibility of the BLUETOOTH wireless speaker to mobile/portable devices differs according to the
various individual devices and, in particular, may vary with different software versions for a device. All
functions are based on industry-wide communications standards. Compatibility between the BLUETOOTH
wireless speaker and mobile device is therefore largely dependent upon the software version of the mobile
device. Other factors (e.g. installation location, walls, distance) mean that in individual cases, sporadic
impairment of functions may occur in devices that otherwise function reliably. Not all functions are
supported in all countries.
Because of these reasons, Kohler Co. can assume no guarantee for the unlimited compatibility and
functionality of your mobile device in conjunction with the BLUETOOTH wireless speaker.

Flushing Your Toilet
IMPORTANT! The flushing action for your toilet is unique. Full flush is a two stage flush designed for
superior performance while using a small amount of water. It will seem as if your toilet is flushing twice.
This is proper operation.
NOTE: When you receive your toilet it is set to flush automatically. The toilet will flush automatically 6
seconds after the user stands up, 60 seconds after use with the seat in the raised position. The toilet will
determine the appropriate flush type ([flush-eco] or [flush-full]) automatically. Refer to the ″Settings -
Auto Open, Auto Flush, Deodorizer″section for instructions on enabling or disabling the auto flush
feature.
NOTE: There are two flushing options. The [flush-eco] option uses 0.6 gallons (2.27 L) of water and is
intended for liquid waste removal. The [flush-full] option uses 1.28 gallons (4.5 L) of water and is
intended for solid waste removal.
For liquid waste removal, select [flush-eco]. The flush takes approximately 30 seconds. There is an
initial flush, then the bowl is refilled.
For solid waste removal, select [flush-full]. The flush takes approximately 45 seconds. There is an
initial flush, the bowl is partially refilled, and a second flush takes place.
