FCC Declaration of Conformity
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Actuate flush
A toilet flush is triggered manually by pressing the buttons on the actuator plate.
For testing purposes, the flush can also be actuated with a Geberit app.
Setting the interval flush
The Geberit HS05 hygiene flush unit is particularly suitable for buildings with high stagnation times in the drinking water pipes. It regularly replaces the drinking water in the pipes, thus preventing stagnation. With the Geberit HS05 hygiene flush unit, only the cold water pipe connected to the cistern can be flushed.
The flush interval and flush time are set with an Geberit app → see “Make settings with the Geberit app”, page 22. The flush time must be selected such that the entire volume of the pipeline to be flushed is flushed.

Troubleshooting
