1. Overview

1. CHARGING THE REDMIKE

Before use, the REDMIKE should be charged. It will take 8-9 hours for the REDMIKE to obtain a full charge. A fully charged REDMIKE will last for over 7 hours of use. If microphones are used daily, they should be stored in the cradle charger after each use. Microphones can be left in a charging cradle constantly for up to 2 weeks without causing degradation to battery life. For longer storage periods, microphones should be fully charged and then taken off the cradle charger until use of the system resumes.

A red light on the charging cradle indicates the REDMIKE is charging. A green light indicates that charging is complete and a full charge has been reached. A blinking light indicates a charging or sensing error. See Troubleshooting section for more information.

REDMIKE incorporates alkaline protection into the microphone design. Always use a Lightspeed rechargeable sensing battery. Replacement AA NiMH batteries may only be purchased through Lightspeed Technologies (part# NH2A27). Do not attempt to charge alkaline batteries. They can overheat and expand creating a signiﬁcant hazard and damaging the microphone (this is not covered by warranty).

1. Plug power cord into the cradle charger and then plug the AC end into an electrical outlet.

2. Place the REDMIKE into the cradle. The REDMIKE will automatically turn off. The LED on the cradle will glow red indicating charging has started. When the REDMIKE is fully charged the LED on the cradle charger will change to green.

2. OPERATING THE REDMIKE

Once the REDMIKE is charged, follow these steps to set it up for use.

1. Turn the 820/855/885 power on. The red LED will glow on the 820 and the blue LED will glow on the 855/885.

2. Remove the REDMIKE from the charging cradle and turn it on.

3. Slip the REDMIKE with lanyard around the neck. The mic will be positioned at approximately the top of the collarbone.

4. While speaking in a normal voice, slowly increase the volume of the corresponding channel on the 820/855/885 until your voice is barely audible. Each REDMIKE has its channel pre-set to either A or B, as indicated on the back of the Mic.

REMEMBER: This equipment

supplements the user’s voice so they are able to speak in a conversational tone. Having the volume set too high will result in feedback and listener fatigue.

5. Once initial volume level is set, walk around the room and listen for audio dropout and overall audio quality. Fine-tuning the audio is accomplished by making minor adjustments to the equalizer on the back panel of the 820/855/885.

6. If a second REDMIKE was purchased, repeat steps 2-4.

3. USING THE REDMIKE TO AMPLIFY EXTERNAL AUDIO EQUIPMENT

The REDMIKE includes a 3.5mm audio input jack to connect to an audio source like a laptop or MP3 player. The REDMIKE will transmit the audio signal to be played through the system.

If your system includes two REDMIKEs, we recommend using channel B (student mic) to amplify the external audio equipment so the teacher’s volume on the channel A (teacher mic) does not have to be adjusted.

To determine which REDMIKE is set to channel B, you can look at the switch on the back of the mic or speak into one of the mics and watch which set of LED’s glow on the front panel of the 820/855/885 (A volume and B volume correspond to channels A or B).

1. Plug your external audio equipment (for example, laptop), into the input on the REDMIKE labeled “INPUT” using a 3.5mm patch cable.

2. Adjust the volume on the 820/855/885 receiver which corresponds to selected mic channel A or B.

1a. Turn the ALD volume control

on the 820/855/885 front panel all the way down (fully counterclockwise).

2. Determine the size and type of audio input jack on the device as many manufacturers’ products differ in connector size and shape. The Lightspeed 370 Personal FM System requires a 3.5 mm to 3.5 mm patch cable (part# MMC3535, not included).

3. Connect a patch cable from

the ALD’s microphone jack or AUX input to one of the following 3.5mm audio jacks on the 820/855/885:

OPTIONAL PAGEFIRST KIT

This optional feature for CAT 855/885 interfaces with an independent classroom paging system. When the page is broadcast, all audio from the system is muted, ensuring important school-wide messages are never missed. Please note that PageFirst is not compatible with telephone or IP-based paging systems.

How it works:

1. PageFirst sensor clip is hung around a lead wire attached to the classroom paging speaker.

2. The clip is hard-wired to the CAT 855/885.

3. As a page is broadcast, the sensor clip detects the audio signal through induction and immediately mutes the CAT 855/885.

4. When the page is over, the audio from the CAT 855/885 returns to normal volume level.

OPTIONAL IR MEDIA CONNECTOR: Initial Set-up

1. Turn off the second microphone. The iR Media Connector (iRMC) uses the same channel (channel B) as the optional second microphone (REDMIKE, LT71, or REDMIKE Share). As a result, they cannot be used simultaneously. If you have a second microphone, turn it off before transmitting audio from the iRMC.

NOTE: If you adjust the CH B volume on the classroom audio system, you will also be changing the volume for your second microphone. Return the CH B volume knob to the original position before turning the second microphone back on.

2. The iR Media Connector volume is preset for most standard audio signals. If you need to turn the volume up or down, follow this procedure:

A. Adjust the volume at the

computer, television, or other audio source if possible.

B. If the audio source does not have a volume control (such as many DVD players) adjust the volume at the iRMC.

C. If the ﬁrst two options do not give optimum volume level, the last place to adjust the volume is the CH. B Volume on the 820/855/885.

820/855/885: AUDIO EQUALIZATION

The 820/855/885 use a 4-band audio equalizer designed to optimize and ﬁne-tune the microphone sound quality for the classroom. Below are some tips on proper system equalization:

• Thevoiceshouldbenatural,

very clear and without any audio feedback (ringing)

• Walktheroomlisteningfor

the overall quality and any feedback that is present

• Ifthereisalotofaudio

feedback, it is likely the volume is too high. Ensure the volume is at the appropriate level, a second person is helpful to determine this.

• Iffeedbackisstillpresent

with the audio set at the right level, make the following EQ adjustments:

– High pitched ring: lower the

2K and/or 4K adjustment by 1/4 turn

– Lower pitched ring: lower

the 500 and/or 1K adjustment by 1/4 turn

• Ifyounoticethesoundis

“muddy” or has too much bass:

– Reduce the 500 adjustment

by 1/4 turn and/or

– Raise the 2K or 4K

adjustment by 1/8 turn

• Note:theEQadjustments
