1.SPEAKER OUTPUTS (1-4): These binding post connectors are used to connect the 850iR to the loudspeakers. Depending on the speaker package, all the outputs may not be used.

2.SPEAKER ON/OFF: These individual speaker switches can be used to turn off the audio in a specific area of the classroom where there may be a learning group or quiet time.

3.DC POWER: Plug the 24 V power supply into this jack.

4.CHARGERS: These jacks charge the LightMic(s) and optional handheld microphone with the supplied charg- ing cable(s) and charging cradle.

5.ALD/AUX AUDIO OUT: These output jacks send audio signal to external equipment such as a recorder or an assistive listening device like the LES-370 Personal FM System.

6.ADJ: These controls adjust the output level of the audio being sent out of the receiver/amplifier via the ALD/AUX AUDIO OUT jacks.

PageFirst: Emergency Page Priority

This optional feature interfaces with an independent classroom paging system. When the page is broadcast, the system is muted, ensuring important and emergency school-wide messages are never missed.

How it works:

1.PageFirst sensor clip is hung around the lead wires attached to the in-room paging speaker.

2.The clip is hard-wired to the 850iR.

3.As a page is broadcast, the sensor clip detects the audio signal though induction and immediately mutes the 850iR.

4.When the page is over, the audio to the 850iR returns to normal.

(For full installation instructions refer to the install sheet included with the optional PageFirst sensor.)
