UHF- Transmitter
Mode of Operation
The transmitter is able to transmit coded signals to a matched receiver via radio transmission. The operation
corresponding to these signals depends on the receiver and its wiring.
It should be noted that for applications that could put human life at risk, by using radio connection
there is always present a potential hazard due to extraneous disturbances.
It is forbidden to modify or change component parts of these product !
Range of operation
The system is designed for large operating ranges up to 1000 meters and even obstructing walls or steel reinforced
constructions can be penetrated.
The range may be reduced for the following reasons:
•
Buildings, vegetation or any other objects will substantially reduce the operating range.
•
The distance between the antenna and the human body or other conducting objects (e.g. Earth)
•
"Background electrical noise" could be relatively high so that the signal-to-noise-ratio decreases and there for the
range.
Also other devices, with similar operating frequency, located within the neighbourhood may disturb the receiver.
•
Operating the receiver next to inadequately shielded electronic boards or other devices (e.g. PC's) that produce
electromagnetic radiation, can substantially reduce the range of operation and could result in an apparent
intermittent operation.
•
It is forbidden to modify, change or manipulate component parts of the product!
Description of Operation
The transmitter SHT-12 C4 is able to control up to 4 different functions of a matched receiver. This could be 4
Signals to only one receiver (e.g. SHR-12 K4) or a number of receivers at different locations.
A green flashing LED acts as a transmission indicator for each signal.
Key stroke
1x Beep:
Device is activated
1x Beep:
Deactivated
3x Beep after 2 seconds: no connection
Each transmitter has an individual serial number. If more transmitters for one receiver are used, than each transmitter
must be programmed to the receiver.
For customized projects it is possible to program all the corresponding transmitters with the same number. You only
need to program the receiver once.
Operating Instructions (GB)
3 flashes per second: The receiver confirms the connection
Multiple flashes within 2 sec.: no connection
Constant blinking: low battery
Depending on the receiver: Either indicates low battery or
confirmation of the receiver.
(please read the corresponding instruction)

Batterij vervangen
De levensduur van de batterij hangt van het gebruik van de handzender af. Indien de reikwijdte sterk verminderd
wordt, of wanneer een functie meer geactiveerd kan worden dan moet de batterij vervangen worden. Hiervoor maakt
u de twee schroeven (4) los en neemt u de behuizingshelften uit elkaar.
Op de juiste polariteit letten!
Uitsluitend 12V-alkaline-batterijen gebruiken!
De lege batterij mag niet met het huisvuil verwijderd worden, maar moet naar een hiervoor
bevoegde instantie gebracht worden. Gebruik hiervoor de openbaar-rechtelijke installaties of de in
de handel opgestelde containers met het GRS-symbool.
Frequentieverandering
Zelden kan het gebeuren dat de in de fabriek ingestelde frequentie door
andere radiotoestellen gestoord wordt. In dit geval kunt u door de
contacten te verbinden (zie rechts) naar de tweede arbeidsfrequentie schakelen.
De bijhorende ontvanger moet dan eveneens naar de tweede
frequentie omgeschakeld worden (zie handleiding ontvanger).
