Connect AC Cord: Insert the female end of the AC power cord firmly into the input port on the main transformer unit.
Connect DC Cord: Plug the 5.5mm O.D./2.5mm I.D. barrel connector of the DC output cord into the 12V DC input jack on your Meade telescope or compatible accessory. Ensure a secure connection.
Connect to Power Outlet: Plug the AC power cord into a standard 110-120V AC, 60Hz wall outlet.
Verify Power: Once connected, the adapter should provide power to your device. Some adapters may have an indicator light to confirm power is active.

Note: Always connect the adapter to the device before plugging it into the wall outlet to prevent potential power surges to your equipment.

5. Operating Instructions

Once properly set up, the Meade 12V DC Power Adapter operates automatically to provide continuous power to your connected device. There are no user-adjustable settings on the adapter itself.

Ensure your device is switched off before connecting or disconnecting the power adapter.
The adapter delivers a steady 12V DC at up to 5 Amps, sufficient for most compatible Meade telescopes, even when operating features like built-in dew heaters at full capacity.
To power off, first switch off your connected device, then unplug the adapter from the wall outlet.

6. Maintenance and Care

Cleaning: Disconnect the adapter from all power sources before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cables to prevent damage.
Inspection: Periodically check the cables and connectors for any signs of wear, cuts, or bends. Replace the adapter if any damage is observed.

7. Troubleshooting

Problem	Possible Cause	Solution
No power to device	Adapter not plugged in. Wall outlet is not active. DC connector not fully inserted. Incorrect DC connector size. Damaged adapter or cable.	Ensure AC cord is securely plugged into adapter and wall. Test wall outlet with another device. Push DC connector firmly into device's input jack. Verify DC connector matches device specifications (5.5mm O.D./2.5mm I.D.). Inspect for damage; replace if necessary.
Adapter feels hot	Normal operation under load. Poor ventilation. Overload (device drawing too much power).	Some warmth is normal. Ensure adapter is in an open area, not covered. Verify device power requirements do not exceed 12V 5A (60W). Disconnect if excessively hot.
