Once the compartment is open insert the batteries as shown: 

 

Ensuring the flat section of the battery is placed on the spring terminals. 

Wearing the unit 

The IR~RX is designed to be worn around the neck using the neck 
loop cable as a support, with the logo face pointing outwards. 

The receiver needs to be over any clothes as it needs to receive the 
infrared light from the transmitter. 

The receiver is very sensitive and can receive clear audio from 
reflected infrared light, but for best operation the user should face 
the general direction of the transmitter(s) 

Controls 

The IR~RX has only one control, a combined volume and ON/OFF 
switch. 

The switch has a positive click action and can be slowly adjusted 
until the correct listening volume is achieved. When using 
headphones near the microphone, feedback may occur in the form 
of a loud whistle, either move away from the microphone or reduce 
the volume control to stop this. 

When using the device with the neck loop, ensure the hearing aid is switched to the “T” position before 
adjusting the volume level. 

If the audio is distorted, either the level is too high, the batteries are low on charge, or the incorrect 
impedance headphones have been used, IR~RX is designed for 32

 headphones and will not work 

correctly with 600

 units. 

 

Important Safety Information 

When using the IR~RX with headphones there is a tendency to use a higher volume than 
for normal listening, this should be avoided as it may lead to long term hearing problems.
