 (SSI # F2h 22h)
Unlock Parameter #

 (SSI # F2h 23h)
This feature locks parameter settings with a 4-digit code to prevent the user from changing parameter values by scanning parameter barcodes. This provides an added level of security not offered via
Disable Parameter Barcode Scanning
.
After locking parameter settings, only the
Unlock
 parameter barcode is accepted with the correct code.
Parameter Barcode Scanning must be enabled in order to scan the
Lock
 parameter barcode. Once parameter scanning is locked, using the
Enable
 or
Disable Parameter Barcode Scanning
 parameter option results in a parameter error beep.
To lock parameter scanning:
  1. Scan the Lock barcode.
  2. Scan four barcodes from Numeric Barcodes that represent the desired code. Enter leading zeros for numbers below 1000, e.g., to program a code of 29, enter 0, 0, 2, 9. A "lock" beep sounds (two long high beeps) in addition to the parameter entry beep.
