Sam4s SPS-300 OP Manual v1.35 Service Mode Programming • 119
Service Mode Programming
Overview
The Service Mode programming is meant to be a one-time event, since the most basic register
and system options are fixed at this time. Changes to the Service Mode programming may
influence the way the machine operates, and it is recommended that they are not done by the end
user.
The Service Mode keylock position is only accessible with the "C" key. This key should be
released to the end user ONLY when they fully understand S-Mode programming procedures.
All S-Mode programming is best done at the dealer level. Existing totals may be reset to zero
accidentally, and the existing program may also be destroyed as well.
The following procedures are done from the Service Mode menu:
• Hardware Tests
• Clear all totals
• Clear grand total
• Clear PLU file
• FLASH ROM Information
• Memory Allocation
• Assignment of functions to keyboard locations
• IRC Options
• RS232C Port Options
• SD Card Operations, including Program Backup and Loading
• Clear Current Batch (Integrated Payment Applications only)
