Maintenance Tips
-
Keep BNC Connectors Clean – Use compressed air or a soft brush to remove dust.
-
Avoid Cable Strain – Do not bend or pull SDI cables sharply; use proper cable management.
-
Ensure Secure Installation – Firmly seat the module in the monitor slot.
-
Use Certified HD-SDI Cables – Maintain optimal signal quality and reduce dropouts.
-
Power Off Before Handling – Prevent damage when installing or removing the module.
-
Inspect Regularly – Check ports and cables for wear, looseness, or signal issues.
