Erika User Manual
With Power Levels 1, 2, and 3, you can expect about 24 hours of battery runtime in Speech Mode, which we
will cover later, and less in Music Mode. With Power Levels 3, and 4, expect about 16 hours of runtime in
Speech Mode. Thus, a side benefit of choosing a lower power level is additional runtime.
Ideally, you will experiment, in your environment, to determine the lowest power level that gives you perfect
audio transmission.
With the lowest power level determined, your Erika Mic will automatically mute when you leave your
approximate area or room. It may not immediately mute when you leave the room, but as you walk further
away, it will. AutoMute is a considerable advantage, as when you leave the room and have a private
conversation or use the facilities, your Erika Mic will probably be muted. Of course, this depends on two
things: you set the power level to the lowest workable power level and left the area. We highly recommend
that you test this feature in your environment.
You may be in a room in many cases, and others may be using Erika in an adjacent room. In these cases, it is
best to set your power level to the lowest acceptable level so that the two Erika systems do not interfere with
each other. Of course, Erika is designed to avoid interference, but it helps when the minimum acceptable
power levels are used.
Firmware Updates
Erika contains firmware, which is fully upgradeable in the field. This function enables us to add features over
time and to fix problems that might occur. While most computers can be used with Erika, a Windows 10
computer is needed for the firmware update process.
The firmware update process is easy.
1.
Download the latest firmware update app from
computer.
2.
Install the app on the computer.
3.
Open the app.
4.
Connect the Erika Mic to your computer using the supplied USB cable.
5.
Click on Update Firmware. The process will take approximately 10 seconds.
6.
Connect the Erika Receiver to your computer using the same USB cable.
7.
Click on Update Firmware. The process will take approximately 10 seconds.
Music and Speech Modes
Erika supports high-quality audio optimized for either Speech or Music, your choice.
Many will use Erika for speech, so Erika comes from the factory optimized for speech.
But, for those that want to use Erika for music, we have a Music Mode.
Enabling Music Mode is accomplished via a quick firmware update.
