SAM4S ER-350II SERIES 3-5
3-3 Operation
3-3-2 Initial Clear
The Initial Clear procedure clears keyboard lock-ups and clears most error conditions. This procedure finishes
the current transaction / operation and clears the Temporary Memory Buffers. An Initial Clear does not affect
register programming. Nor does it erase Totals stored in RAM memory
PROCEDURE
1. Turn the Mode key to the “S” position.
2. Connect the AC Power Plug into a power outlet while pressing the +%, VD and TAX keys.
(The pressing keys are buyer option)
3. After clearing all RAM memory the register prints the following line:
CAUTION: An Initial Clear causes balancing discrepancies if it is performed while in the middle of a transaction.
WARNING: If you ‘Power ON’ the ECR while the display connector on the PCB is open, the initial burst of
current may harm the system. The CPU is especially sensitive to power surges.
WARNING: Do an Initial Clear once only. Doing an Initial Clear more than once erases all programming and
Totals.
