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 860 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 860 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 860.

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

10. 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 860:

• “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 860.

5. With the CAT 860 and ALD turned on, speak into the REDMIKE and slowly adjust the corresponding volume control on the CAT 860 until the appropriate audio level is obtained in the ALD.

11. 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 860 (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 860 receiver which corresponds to selected mic channel A or B.

12. 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

860.

3. As a page is broadcast, the sensor clip detects the audio signal through induction and immediately mutes the CAT 860.

4. When the page is over, the audio from the CAT 860 returns to normal volume level.

(For full installation details refer to the install sheet included with the optional PageFirst sensor clip)

13. RS-232 SERIAL INTERFACE PROGRAMMING

The CAT 860 uses standard RS-232 protocols as a serial link to an external control module such as an intelligent wall panel, or a personal computer. When the Control Select switch in the “RS-232” position, the serial link offers remote access to operational control circuitry within the CAT 860 for the purpose of controlling the volume of the audio input and output ports. Additionally, the serial links allows remote queries of internal CAT 860 system status.

Command and parameter characters travel serially along the RS-232 signal link between the external controller and the CAT 860. The command and parameter information is in the form of two hexadecimal values contained in the 8-data bits of each RS-232 character. The above graphic illustrates a typical RS-232 logic waveform representing a character (Data format: 1 Start bit, 8 Data bits, No Parity, 1 Stop bit). The data transmission starts with a Start bit, followed by the data bits (LSB sent ﬁrst and MSB sent last), and ends with a “Stop” bit.

The voltage of Logic “1” (Mark) is between -3VDC to -15VDC, while the Logic “0” (Space) is between +3VDC to +15VDC.

PROGRAMMING CONT’D

An external controller, in the form of an intelligent wall panel or a personal computer, can use the RS-232 serial link to remotely send commands to initiate actions or queries for the CAT 860. In response, the CAT 860 uses the RS-232 serial link to send acknowledgements or status data back to external controller.

There are two operational command sets; the Basic Command Set for audio switching and the Advanced Command Set for audio mixing. It is not recommended to intermix commands from the two command sets.

The Basic Command Set treats the CAT 860 as a simple audio switcher where only one of four audio/video sources is enabled at one time. The two microphone channels are controlled as a pair independently from the audio/ video sources. The low-cost serial controllers with their limited functionality will typically will be restricted to a subset of the Basic Command Set. These controllers usually cannot utilize the query commands, or the response packets. More capable high-end serial controllers can take advantage of the complete features of the Basic Command Set.

The Advanced Command Set treats the CAT 860 as an audio mixer which is aligned with the traditional usage for Lightspeed CAT 800 series products. The Advanced Command Set requires the more capable high-end serial controllers to utilize the CAT 860 to its greatest potential.

It is expected that each button press from the serial controller would use only a single action/query command packet. If a single button press must issue a string of multiple action/query command packets then each packet must be separated by at least a 10ms delay, or alternately, a new command packet must wait until the CAT 860 issues a response packet/character before it can be sent.

This command determines which volume-level will be affected by the AIDI (<0x92>), AIDD (<0x93>), and AIAV (<0x94>) commands.

If the command is properly received, the CAT 860 responds by repeating back the command packet where the <Param> character contains the selection status.

If the command is not received properly, the CAT 860 responds by sending a <NACK> character.

Power up default is TV/VCR selected.

These items are included for controllers limited to only a single volume control, the three parameters on the left allow the AIDI (<92>), AIDD (<93>), AIAV, (<94>) and AIAV? (<95>) commands to have the same capabilities as the AODI (<A2>), AODD (<A3>), AOAV (<A4>), AOAV? (<A5>), IIDI (<B2>), IIDD (<B3>), IIAV (<B4>), and IIAV? (<B5>) commands.

That is, multiple commands will be able to independently affect the values of the same volume-level EEPROM variables which correspond to the IR CH-A, the IR CH-B, and the AUX OUT. This is true even if the two commands have been directed to the same volume-level EEPROM variable. In this case the EEPROM variable retains the value from the last command issued from the serial controller.

Deﬁnition: This command modiﬁes the volume-level EEPROM variable which was selected by the AICH (<0x90>) command. The EEPROM variable is decremented by the amount indicated in the <param> character.

Afterwards, the value in the EEPROM variable is unconditionally loaded into the corresponding volume control hardware register. This overrides any prior mute operation.

If the command is not received properly, the CAT 860 responds by sending a <NACK> character.

For the audio inputs, the power up default values for all six input volume-level EEPROM variables is set for -40dB.

Deﬁnition: Based on the value in the <param> character, this command unconditionally sends the appropriate EEPROM variable content(s) into the corresponding volume control hardware register(s). None of the volume-level EEPROM variables are modiﬁed.

If the command is properly received, the CAT 860 responds by repeating back the command packet where the <Param> character contains the un-mute selection status.

If the command is not received properly the CAT 860 responds by sending a <NACK> character.

Note: The un-mute operations will override any mute operations performed as part of any command from the Basic Command Set.

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 860.
