MCT-241 (868)
The MCT-241 is a PowerCodeTM miniature, microprocessorcontrolled personal UHF transmitter. It is designed to transmit coded alert signal in distress or in other emergency situations. The transmitter is waterproof and suitable for wearing in a shower.
The transmitter is activated by depressing the recessed oval pushbutton at the center of the unit. A built-in timer determines the transmission time to 3 seconds, even if the user maintains the transmission button depressed shorter or longer than that.
When triggered, the transmitter transmits a unique, factory programmed, randomly selected 24-bit digital alarm code. This code is selected from 16 million possible codes and is therefore unique and virtually impossible to reproduce.
Operating power is obtained from an internal 3V Lithium battery. A red LED (see Fig. 1) lights steadily during the transmission, giving reassurance to the user and indicating that the battery condition is good. If the LED flashes each time the transmitter is activated, it indicates that the battery voltage is low and must be replaced as soon as possible.
The transmitter case is sealed (no screws) to enable the waterproof feature. Therefore, battery replacement can only be done in the factory. If the transmitter is activated while the battery voltage is low, a ‘low battery’ alarm code is transmitted. If the transmitter is not activated for a long period, the battery is self-tested every 12 hours. After three consecutive “low battery” states, a supervisory ‘low battery’ alarm code is transmitted.
The transmitter is supplied with two wearing accessories, a neck cord (to be worn around the neck) and a clip (to be attached to the user belt or shirt pocket).
The neck cord includes a built-in safety release mechanism. This neck cord must never be replaced with a cord that does not include a safety release.
