My product is on, but the display is black. What should I do?
Try the following:
- Make sure the batteries are inserted correctly.
- Replace the batteries with new ones, or use the optional AC adapter (APT0615Z1-1).
Warning: Make sure to use AC adapter APT0615Z1-1 or damage may occur.
- If you are using an AC adapter, make sure that it is securely connected to both the wall outlet and the product.
- Adjust the contrast setting.
