810-digital500 Analog/Digital Audio Transmitter with RC
The product is rated both for telephone line and room acoustics monitoring, with transmission of the obtained intelligence via crystal controlled radio channel.
All operation modes are user-defined and are set with internal keys or with RC. RC unit is optional.
Basic user-defined operation modes:
Room acoustics or Telephone line control (with use of external microphone or inductive sensor accordingly);
Open/encrypted radio channel (delta modulation encoding);
Transmitter output power control (100 mW/450 mW);
VOX ON/OFF;
RC ON/OFF;
Transmitter ON/OFF with use of RC.
The intercepted signal has no attributes of voice information and is recognized as white noise.
Low output power mode (100 mW) guarantees longer operation time of the transmitter and makes it difficult to locate with special detectors. High output power mode (450 mW) increases the range of operation.
The product is equipped with voice activation function which activates the transmitter if triggered by signal from telephone line or microphone and deactivates the transmitter within certain period as the signal is lost. The Voice Activation function guarantees longer operation time.
The product is designed in metal case and equipped with input for external microphone or inductive sensor, input for charger, SMA socket for external universal antenna, power ON/OFF switch and battery low indication.
The product is powered with internal NOKIA BL-5C rechargeable battery. Standard ACP-12E (800 mA) charger for NOKIA phones is used for charging.
Transmitted intelligence is received with the use of special WFM receivers produced by special receiver.
