Erika User Manual
How to Wear the Erika Mic
When wearing Erika, we suggest keeping the microphone in a vertical orientation with the mic port facing
forward and the USB port pointing down, as this helps prevent rain from entering the USB port.
Erika is typically worn in the center of the chest, over the sternum 4 to 5 inches down from the wearer's chin.
Other positions can work well also. If you have an implanted medical device, observe all recommendations
concerning these devices. For example, since the Erika Mic has an embedded magnet and a backing magnet,
keep the magnets at least 6 inches from your implanted devices.
You may also use Erika as a conference room mic; just set it face-up on the table.
After using Erika, you may set the Erika Mic face-down. Or you may disconnect the Erika Receiver from the
USB port. Either way, the Erika Mic will power off. When appropriate, you may use the supplied cable to
recharge Erika.
You may hide Erika behind a lapel, in a pocket, under clothing, or covered with a piece of matching fabric,
with minimal effect on audio quality.
How do I charge the Erika Microphone?
You may use a computer USB port, or an AC Powered USB power supply/charger. Most USB power
banks/batteries will not charge the Erika Mic, as Erika requires so little power that the power bank/battery
will turn off the USB port. Note that attaching an Erika to a laptop, then closing the laptop will STOP the
charging. The Blue LED will flash while charging, and a solid Blue LED indicates a full charge. While charging,
the Erika microphone is muted.
Erika Transmission information
Erika uses 2.4 GHz radio spectrum to communicate between transmitter and Receiver. Erika utilizes random
frequency hopping. This technique improves security and helps Erika to coexist with other 2.4 GHz devices. If
interference does occur, Erika then avoids using frequencies with interference.
AutoMute
AutoMute is an Erika feature designed to help reduce “Hot Mic” moments. The goal is to help prevent private
conversations and embarrassing moments from becoming public. Our AutoMute feature is not a guarantee
that “Hot Mic” moments will never occur, as it requires some action on your part to set up correctly.
AutoMute is a benefit of Erika’s multiple radio power levels. With Erika, you may select an appropriate power
level for your needs. The power levels are numbered 1 to 5, with 1 being the lowest power level, thus the
shortest range. 5 is the highest power level, for the longest range, approximately 300 feet or 91 meters.
We recommend using the lowest power level that suits your needs. For example, many videos are created
with a camera close to the subject. Thus, the distance is relatively short. In this case, the power level of 1 may
be very appropriate. In other cases, Level 2 or 3 may be best. Levels 4
and 5 are the highest power
levels
and use more battery power.
