1. INTRODUCTION
The MCT-241 MD 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-241 MD 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 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 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. OPERATION AND ENROLLMENT
2.1 Transport Mode
New MCT-241 MD 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 the upright position.
This allows the user to prevent an accidental "tilt alarm" message from being
transmitted. If a tilt alarm had been transmitted and the unit was subsequently
returned to the upright position, a "tilt restore" message will be transmitted.
Note: Please refer to the AMBER user manual for further details on this
feature.

2.3 Low Battery Voltage Indication
The battery is automatically tested under load once in 12 hours. If a low
battery state is registered in 3 consecutive tests, a "low battery" message will
be transmitted, and a "low battery" digital marker will be included in every
transmission, "alarm" or "tilt". In addition, when the battery voltage is low, the
LED flashes while the pushbutton is pressed.
2.4 Transmitter Stand
When putting the transmitter away, it is recommended to use the special
stand included in the package (Fig. 5). The stand will maintain the unit in a
vertical (upright) position, thus preventing accidental activation of the tilt
sensor. Place the stand on a flat surface, then insert the bottom end of the
unit into the stand.

2.5 Initial Test
Upon press of the transmission button, the control panel will sound and display
simultaneously CALLING SERVICE BUREAU... until contact is established.
This means that the transmitter is working properly.
Note: If for any reason the MCT-241 MD does not result in the above response
from the control panel, please contact the central station and verify the PowerCode
ID located both on the unit's package and on the reverse side of the transmitter.
2.6 Teaching the Target Receiver
To provide the desired response, the target receiver must "learn" to identify
the Transmitter ID code. Advise the Central Station (either by telephone or by
fax) of the Transmitter ID located both on the unit's package and on the
reverse side of the unit.
