2.  Connect the power cable to the magnetic loop on the back of the case using the power plug. The red indicator light will blink.
3. The indicator light will stay green when charging is complete.

Adjusting the portable magnetic loop

1. Place the portable magnetic loop between the wearer of the hearing aid and the second person on the desk.
2. Make sure that the back of the magnetic loop, equipped with the microphone, is directed towards the person who is not fitted.
3.  The front of the device must face the person with hearing loss.

 Usage

Once the magnetic loop is turned on, you can start your conversation normally:
In normal operation, if the LED lights red when you speak, it indicates that the system is working. If the prosthesis wearer does not pick up a clear signal:

1. Make sure the portable magnetic loop is fully charged.
2. Adjust the position of the buckle on the desk, the holder of the prosthesis should not be more than 1.1 meters from the buckle.
3.  Ensure that the wearer has properly engaged the T-position of the hearing aid.
4.  Ask the wearer of the hearing aid to check the sound volume settings on the hearing aid.

If you have followed the above steps and the prosthesis wearer is still unable to hear a clear signal, this may be due:

• A failure of the loop
• A defect in the wearer’s hearing aid
• The wearer’s hearing aid coil is not activated.

 Additional connections

External microphone
If more than two people are involved in the conversation, it is strongly recommended to use a loop adapted to the large surface area. If you do not have a microphone available, it is nevertheless possible to use an external microphone.

1. Insert the microphone jack into the EXT-IN jack on the back of the unit.
2.  Place the external microphone towards those who speak.

External sound source
To connect the loop to a TV or other external sound source, connect the loop with a jack/jack cable.

1. Insert the jack connection into the appropriate outlet on your sound source.
2. Insert the jack plug into the EXT-IN socket on the back of the portable loop.
3.  Position the buckle so that it faces the wearer of the hearing instrument.

Note: The internal microphone is inactive when the external microphone is connected.

Important information

• A green LED indicates that the unit is functioning properly.
•  If the battery is low, a yellow LED lights.
• The device can be charged while in use.
• When the portable magnetic loop is not in use, it should be connected to its mains charger. This will consume very little power.

Note: The operating time of the device with full charge and not plugged into the mains is approximately 4 hours.
