Volume control
Adjust the volume level on the headset initially to a low volume to protect your hearing.
The volume increases when you turn the dial toward “10” and it decreases when you turn
the dial in the direction of “0”.
Range
EarTech TV Audio uses the newest 2.4GHz technology. In optimal cases the range is up to
30.5 meters (100 feet).
The 2.4GHz radio frequency technology also works through walls. The range depends
greatly on the building and the environment.
Mono/Stereo Switch
You can switch to stereo when using the headset or the 3.5mm output on the neckloop
with earbuds or headphones. When using T-coil enabled hearing aids with the neckloop,
the signal will always be mono.
Battery charging
Once the battery is fully charged, it can be used up to six (6) hours. The operating time may
vary, depending on the listening volume.
Headset: The green LED on the headset will blink slowly and beep every minute when the
battery is low.
Neckloop: When the battery level is low, you will hear 3 beeps every minute in the
neckloop. The neckloop will be switched off automatically after 5 minutes.
After use, gently place the receiver into the charging cradle of the transmitter.
Ensure that the receiver is placed correctly in the transmitter. If the receiver is charging,
the green LED at the right side of the receiver is illuminated. For first time operation, it is
recommended that the battery be charged for at least three (3) hours.
An additional battery can be charged in the transmitter. Additional batteries are available
through your EarTech TV Audio distributor.
The additional battery can be inserted into the charging bay behind the receiver charging
cradle. Please ensure that the sloped side points upward and that you insert it without
applying too much force. The LED on the base is illuminated green when the battery is
charging.
We recommend that you exchange the battery in the receiver with the spare battery in the
transmitter weekly. This ensures that the batteries are used regularly and that they achieve a
maximum service life.
