Cultural Tip
In Latin American Spanish the informal command ‘revisa’ is very common in technical instructions. In Spain you might hear ‘comprueba’ or the more formal ‘verifique’ in written manuals. Remember that ‘interferencia’ stays singular even when you talk about multiple sources, so avoid saying ‘interferencias’.
