Affiliate Disclosure

Some pages may eventually include affiliate links or ads. If you click a link and make a purchase, the site may earn a commission at no extra cost to you.

How affiliate links may be used

Affiliate links should only appear where they are helpful and relevant, such as replacement batteries, smoke alarms, carbon monoxide detectors, chargers, surge protectors, routers, printer supplies, cables, or other items directly related to a troubleshooting guide.

Editorial approach

Affiliate relationships should not change the meaning of a device light or the safety guidance on a page. The main purpose of every guide is to help visitors understand the signal, check safe basics, and find the correct official source when needed.

Advertising

The site may display ads in the future. Ads should not be placed in a way that hides safety warnings, makes troubleshooting steps hard to read, or confuses visitors about what is editorial content.
