Steps to troubleshoot scanner is not working:
1. Remove the Socket scanner from the PDA
2. Look inside PDA CF slot, and make sure all pins are all straight up. If not, this could be the problem.
3. If you have a backup scanner (B) and you know it is working, insert it into the PDA. If the PDA detects this scanner (B), then your current scanner is defective.
4. If you have a backup PDA (B) and you know it is working, insert the scanner into this backup PDA (B). If the PDA (B) detects the scanner, then your current PDA is defective.
