Chronis RTS/RTS L is the programmable radio time switch in the new inteo-control range
from SOMFY,which controls your electrically operated roller shutters or external blinds.
Operating commands are transmitted by radio signal,significantly reducing the cost of installation.
The radio signal has a range of up to 300 metres in free field,or 20 metres through two concrete walls in buildings.
Hereby, SOMFY, declares that this equipment is in
compliance with the essential requirements and other
relevant provisions of Directive 1999/5/EC.

Assembly
1.)Fix wall mounting
plate to the wall
using two screws
3.)Place the cover.2.)Slide the Chronis
RTS/RTS L onto
the wall mounting
plate from above
The range of radio control is limited by laws regulating radio devices and by building design. When planning,please ensure that there is adequate radio
reception.
In order not to affect quality of reception,a minimum distance of 30 cm between a Chronis RTS/RTS L unit and a radio receiver should be maintained.
Chronis RTS/RTS L should not be installed in the immediate vicinity of metal surfaces. Powerful local transmitter equipment (e.g.cordless headphones)
with a transmission frequency identical to the Chronis RTS/RTS L can affect its function.
The equipment is delivered with the batteries installed.
An insulating strip is placed between the battery pole and the contact.
This must be removed before installation,then the time is shown on the display.
