Why Upgrade to V103.5?

1. Bug fixes from earlier versions
2. Improved stability for continuous operation
3. Enhanced compatibility with modern tooling programs
4. Required for memory expansions (like the 8MB PCB-0043)

Installation Process

Before Starting:
1. Back up all machine parameters
2. Have your SETP values recorded
3. Ensure proper ESD precautions

Step-by-Step Installation:

1. Power down the CNC completely
2. Remove the existing program module
3. Install the new PCB-0159 in the same orientation
4. Reconnect all cables securely
5. Power on and initialize the system

Post-Installation Checks:

1. Verify software version shows "103.5"
2. Test basic movements and program execution
3. Confirm all parameters were retained
4. Maintenance Best Practices

To ensure long-term reliability:

1. Keep the control cabinet clean - Dust causes overheating
2. Check connections annually - Vibration can loosen cables
3. Monitor for error messages - Early detection prevents bigger issues
4. Update backups regularly - Especially after parameter changes

Troubleshooting Common Issues

1. Symptom: Version not displaying
Likely Cause: Improper installation
Solution: Reseat the module carefully, ensuring proper connection

2. Symptom: Random resets
Likely Cause: Power fluctuations
Solution: Check voltage supply and stabilize power input

3. Symptom: Parameter loss
Likely Cause: Backup battery failure
Solution: Replace the backup battery immediately
