MC-10 Operation and Language Reference Manual Chapter 3

3/OPERATING THE MC-10 Only after all connections (TV, recorder, printer, and power source) have been made should you power up the Computer. Never turn any accessories on or off while the Computer is in use. Doing so can cause abnormal operation of the Computer or cause it to "hang up". If this occurs, you may have to press the RESET Button (located on the back of the MC-10) or turn the system off and on again. Be aware that when you turn the Computer off, all data currently in memory will be erased. Turning the Power On At this stage, the Computer and all accessories must be OFF! 1. Turn on the TV and adjust the volume to a normal listening level. 2. On the TV, select either channel 3 or 4 (whichever is weaker or not used in your area). 3 On the MC-10, select the same channel by positioning the CHANNEL SELECT Switch (on the bottom of the Computer) to the appropriate setting. 4. Set the Antenna Switchbox to the COMPUTER position. 5. Turn the MC-10 Computer ON. The Power On/Off Switch is on the right side of the Computer. 6. Turn any accessory equipment (printer, cassette recorder, etc.) ON. Your TV Screen should then turn green and display the following message: MICROCOLOR BASIC v.r. COPYRIGHT 1982 MICROSOFT OK where v.r. is a pair of numbers specifying which version and release you have. If the message does not appear: Be sure your TV is turned on and is operational. Check your TV's Brightness, Contrast, and fine tuning adjustments. If the message still doesn't appear, turn the entire system OFF, recheck all connections and try again. For further assistance see "Troubleshooting and Maintenance" later in this manual. Pressing the RESET Button If the system ever "hangs-up" or you ever want to start over, press the red RESET Button on the back of the MC-10. The Screen will clear and the OK prompt should return. Turning the Power Off Always turn the Computer off first-then turn accessories off. If you tune the Computer off for any reason, leave it off for at least 15 seconds before turning it back on again. The Computer's power supply needs that much time to discharge its stored energy before starting up again. Whenever you turn the Computer off, all programs and data in memory are erased. If you have data or programs you want to use again, save that information before turning the Computer off. See "The MC-10 and a Cassette Recorder" later in this manual for details on saving and re-loading information.
