7.1.3 ERROR MEESAGE "CHECK TEMP"
7
CLEARNESS of EEPROM ( When you exchange IC709 )
If recording is operated on CDR-830 at high or low temperature atmosphere, a message "CHECK TEMP" is displayed the operation
halts.
This message is displayed to indicate clearly the problem that would probably happen to recording and playback operation if the
product is placed on a heating object like an amplifier or in a closed space like a rack in which heating object such as an amplifier
causes utmost high temperature, and then if the product is moved into different atmosphere then the problem disappears. The
temperature sensor which is placed inside of the product b70Åé or higher or -15Åé or lower, the message is displayed.
Once this is displayed, all the actions stop. In addition, the product itself has its own temperature rise, outside product threshold
temperature would be a little lower. And these temperatures are not the specification values that guarantee the operation.
After replacing the EEPROM (IC709 mounted on the
system controller), press the SCROLL button and
the MENU button simultaneously with no disc loaded to
initialize the EEPROM.
* It's because EEPROM's with some TEXT and CLIP data recorded
are supplied as spare parts.
* Make sure that there is no disc loaded before the EEPROM
initialization. If a disc is loaded, the TEXT data memorized in
the SRAM will be recorded in the EEPROM at the same time when
the tray opens.
