Operation

Initial Operation

1. Make sure the TV7400 is plugged into the mains supply.

• Make sure the TV Headset is switched OFF (see figure (1)).

Routine Operation

1. Switch on the Audio Source (TV set or other audio device) that the Transmitter is connected to. The Power LED Indicator will glow continuously (see figure (3)).
2. Put the Ear Phone plug into the 3.5mm phone jack of TV Receiver. On the TV Receiver, switch ON the On/Off Switch (see figure (4)). The green Power LED Indicator will glow continuously.
