indicates the ROM checksum used for ROM collection, and if the unit is not loaded with ROM, "NO" appears. When the TUNING UP button is pressed, the sub micro computer program filing number (ex. S90_***" for MA678_90) appears. The *** digit indicates the ROM checksum used for ROM collection, and if the unit is not loaded with ROM, "NO" appears. 4. When the MEMORY button on the remote controller, the function is switched to "Input Inspection Mode", which output analog input signals at L channel of VCR analog input to all channels. 9.4. Returning to Normal Display
Press the POWER button on the unit to exit the function. The power is turned off.
