Page 23: Step 6. Audio Integration
6. AUDIO INTEGRATION The next step in setting up your CAT 860 system is to connect it to the other multimedia devices in your classroom. You may have a computer, television, DVD/VCR player, a visual projection system or other devices. Below are instructions on how to integrate TV/VCR, CD/DVD or computer directly into the CAT 860. -
Page 24: Step 7. Charging The Redmike
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. - Page 25 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.

Page 30: Rs-232 Serial Interface Programming
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. -
