7. 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 kept in the cradle – microphones can be left in a charging cradle constantly for up to 2 weeks without causing degradation to battery life.

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 # BA-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. Ensure that the REDMIKE is turned OFF.

3. Place the REDMIKE into the cradle. 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.

8. SETUP AND OPERATION OF REDMIKE

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

1. Turn the CAT 855 power on. The blue LED will glow.

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

3. Slip the REDMIKE with lanyard around the neck and position the top of the microphone just below the collarbone. NOTE: Positioning of the REDMIKE is critical for proper volume adjustment.

4. While speaking in a normal voice slowly increase the volume of the corresponding channel on the CAT 855 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 4-Band Equalizer on the back panel of the CAT 855.

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

OUTPUT TO PERSONAL ASSISTIVE LISTENING DEVICE (ALD)

1. Turn the ALD (Assistive Listening Device) volume control on the back 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 LES-370 Personal FM System requires a 3.5 mm to

3.5 mm patch cable (part# CAMMC3535, not included).

3. Connect a patch cable from the ALD’s microphone jack or AUX input to one of the following

3.5mm audio jack on the CAT 855:

• “ALDOUT”onthefrontpanel

• “AUXOUT”onthebackpanel

4. Adjust the volume control on the ALD’s receiver to maximum output. NOTE! This is to set the maximum allowable signal from the CAT 855.

5. With the CAT 855 and ALD turned on, speak into the REDMIKE and slowly adjust the corresponding volume control on the CAT 855 until the appropriate audio level is obtained in the ALD.

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 mike) to amplify the external audio equipment so the teacher’s volume on the Channel A (teacher mike) 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 mike or speak into one of the mics and watch which set of LED’s glow on the front panel of the CAT 855 (A Volume or 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 CAT 855 receiver which corresponds to selected mic channel A or B.

PAGEFIRST: PRIORITY MUTE

This optional feature 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.

How it works:

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

2. The clip is hard-wired to the CAT

855.

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

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

3. Slip the LT-71 with lanyard around the neck and position the top of the microphone just below the collarbone. NOTE: Positioning of the LT-71 is critical for proper volume adjustment.

4. While speaking in a normal voice slowly increase the volume for Channel B on the CAT 855 until your voice is barely audible.

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.

REDMIKE Share: Initial Set-up

1. Ensure the CAT 855 is ON. The RED LED on the power switch will glow.

2. Turn on the REDMIKE Share by sliding the switch to the top position.

3. Grip the barrel in the center section. Avoid covering the

infrared emitters circling the base. This could interrupt signal transmission.

4. While speaking in a normal voice, increase the B VOLUME level until your voice is barely audible.

REMEMBER: This equipment is designed to supplement and distribute 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.

INITIAL SET-UP: OPTIONAL IR MEDIA CONNECTOR

1. Turn off the second microphone. The iR Media Connector uses the same channel (channel B) as the optional second microphone (REDMIKE, LT-71, 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 CAT 855.
