Radio operation
The transmission of a switching command from the transmitter to
the receiver takes about 80 to 100 ms, based on the sWave® data
transmission. The switching signal from a transmitter may not be gen-
erated at a shorter interval, otherwise the signal will be suppressed.
The receiver must conform to the sWave.NET® protocol of the steute
modules. To avoid too fast actuation, there is, by default, a delay time
of 1 s when processing one switching command from transmitter to
receiver (if the radio interface is unoccupied and there are no repeat
telegrams). The preset delay time of 1 s can be adjusted from min.
125 ms to max. 31.9 s (see RF RxT SW868/915/917/922-NET,
»Description of interface/Wireless receiver«, section »StateMes-
sage-Response«, paragraph »RECORD.CYCLETIME«, download
from www.steute.co.uk).

Battery
The battery charge is displayed in the description of interface in par-
agrph »RECORD.BATT« as mV (see RF RxT SW868/915/917/922-NET,
»Description of interface/Wireless receiver«, section »DataMessage«,
download from www.steute.co.uk).
When the battery voltage acc. to the radio protocol drops below approx.
<3200 mV (at 20°C, load approx. 20 mA), it may be assumed that the
battery is empty.
Attention: The open circuit voltage measurement
does not provide reliable information!
In order to ensure reliable func-
tioning, the battery must be replaced.

Maintenance and cleaning
We recommend regular maintenance as follows:
1. Removal of all dirt particles.
Clean enclosure on the outside only. Clean enclosure with household
cleaning agents. Do not use compressed air to clean.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately. Dispose of possibly contained
batteries correctly.
