1. 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 Figure 1 - Using the MCT-241
unique and virtually impossible to reproduce. * An alarm system with PowerCodeTM receiver or interface (like POWERMAX, MCR-308, EXP-1600W, etc.), in which the RFR-4 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. Figure 2 - MCT-241 with Neck Cord
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. Figure 3 - Clip Attachment

3.1 Product Limitations
• 868.95 MHz (wide band) is allowed in all EU member states
Our wireless systems are very reliable and are tested to high • 869.2625 MHz (narrow band) is not restricted in any EU
standards. However, due to their low transmitting power (required by FCC, DTI and other regulating authorities) there are some limitations to be considered: 3.3 Battery Replacement/Handling
A. Receivers may be blocked by radio signals occurring on or
The internal Lithium battery replacement can be done only in the near their operating frequencies, regardless of the code Since the product has a Lithium battery, please observe the B. A receiver can only respond to one transmitted signal at a time.
C. Wireless equipment should be tested regularly (at least once
• Do not dispose of batteries in fires. a week) to determine if there are sources of interference and 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
• Do not expose to temperatures in excess of 60°C • 433.92 MHz has no restriction in any EU member state.
