SVS SHT-12 C4D 4-Channel Hand-Held Transmitter

Please read carefully!
These operating instructions form an integral part of this product and contain important information on how to commission, install and operate it. They must be taken into consideration and given to the end user or other third party when the installer hands over the product. These operating instructions must be retained for future reference.
Damage resulting from abuse or misuse is not covered by warranty. The manufacturer accepts no warranty for consequential losses that may result directly or indirectly from use of this equipment. Any changes or modifications not expressly approved by the party responsible for compliance could void the user´s authority to operate the equipment.
The product meets the requirements of the current European and national guidelines for electromagnetic compatibility. Conformity has been established and the relevant statements and documents have been deposited at the manufacturer.

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.
The Operating Instructions need to be followed at all times.
It is forbidden to modify or change component parts of these product.

System operating range

The system SH-12 is designed for a large operating range of many hundred meters. Walls including steel reinforced concrete can be penetrated. The maximum range can be achieved under optimum conditions and by line-of-sight contact between transmitter and receiver without disruption by external high frequency disturbances.
The following are possible causes that could reduce range of operation:

Obstructing buildings, vegetation or other factors will substantially reduce the operating range.
The distance between the antenna and the operator’s body or other conducting objects (e.g. Earth) may influence the working range.
Background “electrical noise” could be relatively high so that the signal-to-noise-ratio may decease and therewith the operating range. Also other devices, with similar operating frequency, operated in the neighborhood of the receiver may reduce the sensitivity.
Operating the receiver adjacent to badly shielded electronic components (e.g. PC’s) that can produce electromagnetic distortion, may severely reduce the range of operation and could result in intermittent operation.
Adjustable and open components should not be adjusted or modified.

Description

The transmitter is able to control up to 4 different functions of a matched receiver (e.g. SHR-12 K4). The user gets information about the radio system and the communication by following visual and auditory signals:

LED 1 (blue) flashes 3 times per second while pressing a button: Proper reception is acknowledged
LED 1 (blue) double-flashes 3 times per second while pressing a button: Proper reception is acknowledged and transmitter battery is low
LED 1 (blue) flashes often within 2 seconds: The receiver does not answer
LED 2 (red) blinks 3 times: Weak receiver supply
LED 2 (red) blinks 8 times: Critical receiver supply
1 x Beep = switch on acknowledgement received
1 x Beep = switch off acknowledgement received
3 x Beep after 2 seconds: No switch on acknowledgement received
3 x Beep after another 2 seconds: No switch off acknowledgement received

SH-12 receivers acknowledge a proper reception by using the weak receiver supply signal.
Each transmitter has an individual serial number. If more transmitters for one receiver are used, than each transmitter must be programmed to the receiver.

Battery change
Depending on the frequency of use the battery life can vary. If the transmitter signalizes low battery or typical range of operation weakens substantially or the transmitter is without function, the battery should be replaced. Open the housing and replace the batteries.
Pleas check for correct polarity! Use only 12V-Alkaline batteries!

Frequency change
In rare cases it is necessary to change the frequency because of interference from other devices. In this case switch to the second frequency ( f2 ). (right picture) Therefore you have to open the housing. Please note that the corresponding receiver should have the same frequency (see the receiver instruction).
