Pairing of the transmitter and the receiver

If you want to add additional receivers (headsets or neckloops) to the transmitter, then the new receivers must first be paired with the transmitter. This is required to ensure that the transmitter and receivers recognize each other and that they can transmit the encrypted data.

This is only required once for each additional receiver. A maximum of 4 headsets or neckloops can be paired with a transmitter.

If the receiver does not find a transmitter, then the red LED 4 blinks and no signal will be received.

Balance control

(Digimax RF under the chin headset receiver and the 3.5 mm stereo output of the neckloop.)

The balance controls the volume distribution between the right and the left ear with the head set or when the 3.5 mm stereo output is used on the neckloop with earphones, headphones or induction hooks. Adjust the balance so that you have the same volume level in both ears.

The balance adjustment does not work when the neckloop is used with hearing aids.

Tone control

(Digimax RF under the chin headset receiver and Digimax RF neckloop)

The tone control is used to adjust the frequency response independently in the left and right ears on the headset.

For the neckloop, the (R) tone control adjusts the sound of both the right and left equally.

Volume control

Set the volume to a comfortable listening level by rotating the volume control from low to high (0-5).

Transparent cover

A transparent cover (included) may be installed to protect the volume control against unintended adjustments and against contamination by dust or fluids.

Remove both rubber covers and click the transparent cover into the openings.

Range

Digimax RF uses the newest 2.4GHz technology. In optimal cases the range is up to 145 feet.

The range depends greatly on the building and the environment. The 2.4GHz radio frequency technology also works through walls.

Battery charging

Once the battery is fully charged, it can be used for up to six (6) hours. The red LED 4/13 starts flashing once the battery is almost empty. The battery should now be charged or exchanged. The operating time is dependent on the listening volume.

Cleaning and care

Cleaning the transmitter and the receiver

If the device becomes dusty or dirty, you can clean it with a soft, clean and damp cloth.

Please disconnect the transmitter from the power supply before cleaning.

Cleaning the silicone ear adapters

After use, put the receiver into the charging cradle of the transmitter, without applying pressure.

Ensure that the receiver is placed correctly. If the receiver is charging, the red LED 18 at the left side of the receiver is illuminated. The LED 18 is illuminated green as soon as the battery in the receiver is charged. For first time operation, it is recommended that the battery be charged for eight (8) hours.

You can remove the ear adapters from the fixture. Clean the ear adapters with mild soapy water. Dry the ear adapters thoroughly and reattach them.

An additional battery can be charged in the transmitter. Additional batteries are available through your Digimax RF distributor.

The additional battery can be plugged into the side charging bay 19. Please ensure that the sloped side points upward and that you insert it without applying too much force. The LED 20 is illuminated red when the battery is charging. If the LED 20 is green, it is ready for use.

We recommend that you exchange the battery in the receiver with the optional spare battery in the transmitter weekly. This ensures that the batteries are used regularly and that they achieve a maximum service life.

All batteries lose their capacity over time. This is characterized by a shorter usage time.

Replacing the silicone ear adapters

The hypoallergenic silicone ear adapters should be replaced if they become worn or damaged.

New silicone adapters can be ordered from your Digimax RF distributor.
