Based on the NW8 Manual and Troubleshooting documentation, here is a step-by-step guide to reset the camera on the NW8 Fundus Machine (TRC-NW8 Non-Mydriatic Retinal Camera):

Step-by-Step: Resetting the NW8 Fundus Camera

1. Power Off the Machine

Locate the power switch on the main unit.
Turn OFF the power completely.

2. Disconnect the Digital Camera

Gently unplug or detach the digital camera connection cable from the main unit. (Including the cable that connects to the flash)

3. Check and Reconnect Camera Connection

Make sure the camera is seated correctly and the connector is not loose or damaged.
Reconnect the digital camera cable securely to the appropriate port on the instrument.

Note: If using a digital SLR camera, ensure it has no battery inside and receives power solely from the fundus unit.

4. Power the Machine Back On

Once the camera is securely connected, turn ON the machine using the main power switch.

5. Perform a Camera Reset Using the Green-Dot Buttons

Locate the two buttons with green dots (typically on the top of the attached digital camera).
Press and hold both buttons simultaneously for a few seconds.
Continue holding until the screen blinks off and then back on.
This signals that the camera reset has been triggered successfully.

6. Confirm the Error is Cleared

Test the unit with a test patient and see if the issues you were experiencing are gone!

Additional Notes & Safety Warnings

Do not attempt to disassemble the unit beyond cable reconnection. Internal repairs should be performed only by trained service personnel.
Always ensure the cover is closed during operation—an open cover may trigger an “INTERLOCK ERROR!!”
