1. INTRODUCTION
. INTRODUCTION. INTRODUCTION
. INTRODUCTION
The MCT-241 is a PowerCodeTM 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 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.

3.1 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 occurring 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.
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.
3.2 Frequency Allocations for Wireless
Devices in European (EU) Countries
• 433.92 MHz has no restriction in any EU member state.
• 315 MHz is not allowed in any EU member state
• 868.95 MHz (wide band) is allowed in all EU member states
• 869.2625 MHz (narrow band) is not restricted in any EU
member state.
3.3 Battery Replacement/Handling
The internal Lithium battery replacement can be done only in the
factory.
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.
