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 Te st

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.

2.7 Entering Sleep Mode

This feature helps to preserve battery life.

1. Position the transmitter horizontally on an even surface.

2. Press the transmitter's button for at least ten seconds.

3. As soon as the LED starts to blink, remove your finger from the button.

4. Press the button again (short press).

The unit blinks twice indicating that the unit is in sleep mode. The
transmitter immediately becomes operational upon a single press of
the button.

4. MISCELLANEOUS COMMENTS

4.1 Product Limitations

Our wireless systems are very reliable and are tested to high
standards. However, due to their low transmitting power (required by
FCC, DTI and other regulating authorities) there are some limitations
to be considered:
A. Receivers may be blocked by radio signals on or near their

operating frequencies, regardless of the code selected.

B. A receiver can only respond to one transmitted signal at a time.
C. Wireless equipment should be tested regularly (at least once a

week) to determine if there are sources of interference and to
protect against faults.

4.2 Battery Handling

Since the product has a Lithium battery, please observe the following
handling instructions:

• Do not dispose of batteries in fires

• Do not short circuit

• Observe correct polarity of cells

• Do not crush

• Do not puncture

• Do not open

• Do not dismantle

• Do not expose to temperatures in excess of 60°C

ATTENTION! The internal Lithium battery can be replaced in the
factory only.

4.3 Compliance with Standards

The 315 MHz version of this device complies with Part 15 of the FCC
Rules. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) This device must
accept any interference received, including interference that may cause
undesired operation.

WARNING! Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the
user's authority to operate the equipment.

The digital circuit of this device has been tested and found to comply
with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in residential installations. This
equipment generates uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio and television reception.
However, there is no guarantee that interference will not occur in a
particular installation. If this device does cause such interference,
which can be verified by turning the device off and on, the user is
encouraged to eliminate the interference by one or more of the
following measures:
– Re-orient or re-locate the receiving antenna.
– Increase the distance between the device and the receiver.
– Connect the device to an outlet on a circuit different from the one

which supplies power to the receiver.

– Consult the dealer or an experienced radio/TV technician.
