Description:
- Matrix flashes "R" and "-" at power up.
- If pressing Softclip it will show "L" (as if the unit was powered on while holding the Enter- or OK button)
- If choosing "S", the unit works normally.
These messages will "normally" occur if the battery is low.
The problem could be due to a SRAM chip which draws too much current from
the battery.
Please check if the SRAM chip ( IC8 ) is marked "ISSI".
We have found that this brand of chip drains the battery way too fast.
The remedy is to replace this "ISSI" SRAM chip with another brand and the battery.
