Setup
- Identify the Power Port: Locate the DC input power port on your Capello CR10 or CR10W Glow Clock Alarm. This port is typically a small, circular opening.
- Connect the Adapter: Carefully insert the barrel connector end of the GUY-TECH AC Adapter into the power port of your Capello device. Ensure a snug fit.
- Plug into Outlet: Insert the two-prong plug of the AC adapter into a standard wall electrical outlet (100V-240V).
- Verify Connection: The LED indicator on the adapter should illuminate, confirming that power is being supplied. Your Capello device should now power on or begin charging.

Operating Instructions
Once the GUY-TECH AC Adapter is correctly connected to your Capello CR10 or CR10W device and plugged into a live electrical outlet, the adapter will automatically supply power. The LED indicator on the adapter will glow to confirm active power delivery. Your Capello device should then function as expected, receiving the necessary power for operation. No further user interaction is required for the adapter itself during normal operation.
Maintenance
- Keep Dry: Ensure the adapter and its connectors remain dry. Avoid exposure to liquids or high humidity.
- Temperature: Do not expose the adapter to extreme temperatures, either hot or cold. Store and operate within typical indoor environmental conditions.
- Cable Inspection: Periodically inspect the power cord and connectors for any signs of damage, such as fraying, cuts, or bent pins. If damage is observed, discontinue use immediately.
- Cleaning: To clean the adapter, unplug it from the wall outlet and wipe it gently with a dry, soft cloth. Do not use liquid cleaners.
- Storage: When not in use for extended periods, unplug the adapter from both the wall outlet and the device. Store it in a cool, dry place.
