NOTE

FCC ID can be found on the bottom of the units.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC

Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated

in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, but if not installed and

used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this

equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the

interference at their own expense.

COMPLIANCE WITH FCC REQUIREMENT 15.407(C)

Data transmission is always initiated by software, which is passed down through the MAC, through the digital and analog

baseband, and ﬁnally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital

baseband portion will turn on the RF transmitter, which it then turns o at the end of the packet. Therefore, the transmitter will

be on only while one of the aforementioned packets is being transmitted. In other words, this device automatically discontinues

transmission in case of either absence of information to transmit or operational failure.

RADIO FREQUENCY (RF) EXPOSURE WARNING

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio

frequency (RF) Exposure Guidelines. This equipment should be installed and operated keeping the radiator at least 20cm or

more away from person’s body (excluding extremities: hands, wrists, feet and ankles).

PAIRED MODE

MICROPHONE CONNECTED TO A RECEIVER

When a Teacher Microphone is linked to the receiver and the E2 buttons are pressed simultaneously

for 3 seconds or more the Teacher Microphone immediately sends an alert message to the receiver.

(MIC1/Power/MIC2 indicator: lights red.) The microphone continues to transmit audio before, during,

and after the alert message is sent. (If the microphone is moved to the Audio Mute Area* or the wireless

connection breaks location, the status changes from a linked alert to a non-pair alert.) Audio mute area:

Refer to Command List [SAA].

Even when the Teacher Microphone is o, an alert can be sent by pressing the E2 buttons on the

microphone. If the microphone is able to connect to its linked receiver, it will be in a linked alert state. (If

the microphone can not connect to its linked receiver, it will be in a non-pair state.)

NON-PAIRED MODE

MICROPHONE ISN’T CONNECTED TO A RECEIVER

If the Microphone is not linked to the receiver and the E2 buttons are pressed for 2 seconds or more:

1. The microphone uses the ALL command to search for nearby receivers.

2. The ﬁve closest receivers will return a signal to the microphone, helping software plot the E2

alert’s location on.

3. The Microphone will repeat #2 every 30 seconds until the microphone is turned o.

(MIC1/Power/MIC2 indicator: there is no change.)

*The microphone in non-linked mode never transmits audio.
