For sale in the following countries: All countries in Europe and North America In the Classroom Using the Neck Cord Attachment, the teacher wears the Microphone when instructing the whole class. The teacher‘s conversation is trans- mitted to the student wearing the Pendant Receiver with enhanced clarity up to 25 metres away. During group discussions, the student may wish to place the Microphone on his or her desk, and point it at whoever is speaking at the time. One-to-One Conversation At home, most couples do not spend all of their time together in the same room. Have your companion wear the Microphone using the Neck Loop Attachment. By wearing your Receiver, you will hear the other person with clarity and be able to converse at comfor - table levels, despite being in different rooms. This mode of use can also be employed when out and about, whether shopping or simply going for a walk, allowing relaxed conversation.

Declaration of Conformity GLENTRONICS LTD. 64 Mallusk Road Newtownabbey Co. Antrim BT36 4QE Type of Equipment: Radio Microphone & Receiver Model: Conversor 16 1 At a Lecture or Conference The Conversor has a unique tech- nology that gives you the ability to listen to speakers clearly from a considerable distance. There are two ways to achieve this: Hold the Microphone in your hand and point it at the source of desired sound up to 15 metres away. In a large quiet room, you can use the Zoom setting at a high sound level to focus on a distant speaker. Or, place the Microphone on the lectern, or ask the speaker to wear it using the Neck Cord Attachment. The Microphone will transmit the speech up to 25 metres away with enhanced sound level and clarity to your hearing aid. Out Shopping Place the Microphone on the countertop to hear the shop assistant clearly. Or, if you have a child who is hard of hearing, you wear the Microphone and your child wears the Pendant Receiver. Your child will be able to hear your voice loud and clear anywhere in the store. Held in your hand, pointed at the speaker Placed near or worn by the speaker Welcome!

F3-Conversor Transmitter USA Frequency Band 216MHz Circuit Diagram Description: This circuit description should be read in conjunction with the circuit diagram (PCB01AKZ.) from Conversor Limited. The F3- Conversor transmitter is a phase lock loop (PLL), narrow band, frequency modulated (FM) radio transmitter operating in 216MHz frequency band and is used for transmitting audio signal. There are two possible ways to input the audio signal into the F3-Conversor transmitter and they are by Microphone mounted in the device (Con2) or direct connection socket (Con1). The microphone Mic-EL3078 is a two port device, directional and omidirectional and by mechanically (TS1) closing the omidirectional port of the microphone, the device become highly directional selective. IC1 and its associated circuitry form an audio amplifier, filtering and buffering circuit. This part of the circuit also form an audio input limiter with limiting diodes. There are two possible audio amplifier gains, “LOW” or “HIGH” and they can be selected by using slide switch (SW1) that also switch “ON” or “OFF” the F3- Conversor Transmitter. The device’s ON, OFF, or low battery states is indicated by the green LED (D2) on the F3- Conversor Transmitter. TR2 and its associated circuitry form the Voltage Controlled Oscillator (VCO) that generated the transmitted radio frequency or the carrier frequency signal. The VCO centre frequency is set by variable capacitor (VC1). The transmitted radio frequency is controlled and locked by IC2 that is programmed by IC3 with a 10 MHz reference frequency oscillator (TCXO). IC2 and its associated circuitry form the is the phase lock loop (PLL). IC3 is a microcontroller that is pre-programmed (Con5) to control and set the transmitted radio signal using IC2. The locking radio transmitted frequency data is programmed into the IC2. VD1 is used to module the audio signal on the radio frequency signal and also to control the transmitted radio frequency with IC2. TR3 and its associated circuitry form a buffer RF amplifier and a band pass filter. TR4 and it associated circuit form the RF power amplifier with a band pass filter that is tuned using variable capacitor (VR2). IC4 and its associated circuitry is a DC-DC converter with a battery output voltage range 1.2V to 1.5V that convert to a fixed output voltage of 3.3V. The battery is charged by the connector (Conn4) and is protected by fuse (F1).

The EUT is intended to be operated under the LPRS rules of CFR 47 part 95G. The EUT utilises the extra band channels listed in part 95.629(c). The sample tested was set to use the channel with centre frequency 216.025MHz. The EUT has an integral antenna. In normal use it is powered from an internal battery. The battery can be charged from an external adapter. Details of the EUT and associated peripherals…
