Hand Held Products 3700 CCD manual Diagnostic Procedure, Troubleshooting Checklist

5.2.2Diagnostic Procedure

The SCANTEAM 3700 Machine Mount CCD may be reset to the last saved configuration parameters by issuing a Reset Command. (A list of these parameters may be found on in section 4.6 and C.4.)

•To perform a Reset Command, send an <A> serial command to the 3700. This action causes all data in memory to be erased and the current user configuration parameters to be loaded from non–volatile memory. In the absence of a user configuration, the default configuration is loaded into memory. This action allows the user to clear memory of any corrupt data from scanned data.
