1. INTRODUCTION
1. INTRODUCTION
The MCT-241MD RL is a miniature,
microprocessor-controlled personal UHF
transmitter. It is designed to transmit coded alert
signals manually (when the user presses the
button) or automatically (when the user falls
down). The transmitter is waterproof and suitable
for wearing in a shower. Operating power is
obtained from an internal 3V CR-2 Lithium battery.
Transmission is initiated in the following cases:
!
Depressing the recessed oval pushbutton (see
Fig. 1). A built-in timer determines the
transmission time to 3 seconds, even if the user
maintains the button pressed shorter or longer
than that.
!
Tilting the transmitter by more than 60° in any
direction. In this case, the 3-second transmission
will take place after a 2- second delay.
When triggered, the MCT-241MD RL transmits a
unique 24-bit digital ID, randomly selected in the
factory. This code is one of 16 million possible code
combinations and is therefore virtually impossible to
reproduce. The ID code is followed by the
appropriate digital marker that indicates an “alarm”
or a ‘fall-detector” event, as the case may be.
A red LED (see Fig. 1) lights steadily during
transmission, to reassure the user that a
transmission is taking place and to indicate that
the battery condition is good. If the LED flashes
each time the transmitter is triggered, this
indicates that the voltage is low and the battery
must be replaced as soon as possible.
If the transmitter is triggered while the battery
voltage is low, a ‘low battery’ digital marker is
included in the transmitted message. In addition,
the battery is self-tested every 12
hours. A
supervisory ‘low battery’ message is transmitted
after detection of 3 consecutive “low battery” states.
The transmitter case is hermetically sealed (no
screws) to ensure complete waterproofing of the
case. Battery replacement can therefore be carried
out in the factory only.
The transmitter is supplied with two wearing
accessories, a neck cord (to be worn around the
neck - see Fig. 2) and a clip (to be attached to the
user belt or shirt pocket - see Fig. 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.

2.1 Transport Mode
New MCT-241MD RL units are shipped with the tilt
(fall-detector) function in ‘deep sleep”, to prevent
inadvertent transmissions until the unit is placed
into service. To ‘awaken” the tilt function, the
alarm pushbutton must be pressed at least 5 times
in succession.
2.2 Tilt Alarm/Tilt Restore
A built-in tilt sensor is activated once the unit is
tilted over by more than 60
°
in any direction. The
Base Unit will notify the user after 30 seconds, and
the actual tilt alarm transmission to the central
station will take place after an additional 30-second
delay, throughout which the unit may be restored to
