MCT-241
Pendant Transmitter
1. INTRODUCTION
The MCT-241 is a PowerCode
TM
miniature, microprocessor-
controlled 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 (see Fig. 1). 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 case is waterproof, hermetically sealed (no screws) and
therefore disposable. Do not attempt to open the transmitter case or
replace the battery; such action will void the warranty.
The transmitter is supplied with two wearing accessories, a neck
cord (to be worn around the neck - see figure 2) and a clip (to be
attached to the user belt or shirt pocket - see figure 3).
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.
