6.4 Receiver Synchronisation to new RF Channel
The transmitter features an automatic RF channel synchronisation. It will automatically find its corresponding
transmitter and adjust its RF channel to the new channel.
NOTE
!
After the first activation of the transmitter, following a RF channel change, it can take up to 1
minute before the receiver will have adjusted itself to the new RF channel and is ready for
operation.
6.5 Re-Activating the TransKey RF Channel
The RF channel programmed by the factory remains stored in the TransKey and can be re-activated if
required.
⇒
Bring the transmitter unit into programming mode (see above). If already in programming mode continue
with the next step.
⇒
Holding both and pressing
Enter Enter
re-activates the RF Channel stored in the TransKey stored.
⇒
The STATUS LED changes from blinking red to permanent red, all other LEDs are off.
⇒
In order to take the transmitter into operation it must be turned off and on again.
⇒
It now transmits on the RF channel stored in the TransKey.
6.6 Indication of the Interference Field Strength
This is a helpful feature to determine whether other systems are transmitting on the currently selected RF
channel. The level of interference, i.e. the field strengths of such systems can be indicated. The interference
field strength is displayed via the S
tatus LED in combination with the internal acoustic buzzer signal.
In the event that there is interference on the selected RF channel, it is recommended that a different, free RF
channel is selected.
NOTE
!
This feature is not available for the 869 MHz frequency band.
⇒
Bring the transmitter unit into programming mode (see above). If already in programming mode continue
with the next step.
⇒
Press the HORN push-button briefly.
⇒
If there is any interference, its severity will be indicated by a combination of the STATUS LED and the
internal buzzer for 3 seconds. There are 3 levels. See the below table.
⇒
Should there be no interference, exit the programming mode by turning the unit off.
Status LED Buzzer Interference Corrective action
green no sound low None required
Status LED Buzzer Interference Corrective action
orange no sound medium If possible change the RF channel
Status LED Buzzer Interference Corrective action
red sounding high The RF channel must be changed
NOTE
!
The field strength received from other transmitters should be as low as possible in order to avoid
possible interference of the radio path between the transmitter and the receiver.
