The display on my PCM70 is garbled. Is there anything that I can do to correct this?
The PCM70 has extensive protection against power line noise, etc. but can still have its memory become scrambled by power line noise, glitches, etc.
You can try the following to correct the problem. BE AWARE however, that the second option listed here WILL CLEAR THE ENTIRE MEMORY, INCLUDING REGISTERS.
1. Turn off the power switch for a few moments, then turn it back on. When the software version number appears on the display, press the 8 key.
2. After a few moments you will be asked: CLR ALL BUT REGS
3. Press the LOAD key. The display flashes: CLEARING
If this fails, try the following: (REMEMBER, ALL MEMORY CLEARED)
1. Turn off the power switch for a few moments, then turn it back on. When the software version number appears on the display, press the 0 key.
2. After a few moments, you will be asked: CLEAR MEMORY?
3. Press the LOAD key. You will be asked: ARE YOU SURE?
4. Press the 1 key. The PCM70 will briefly flash: CLEARING MEMORY and then load program 0.0. All registers will be erased and all control parameters will be returned to factory presets.
Your display may be pretty garbled but you should be able to tell when the listed steps occur.
