Some newer model NWR receivers, including but not limited to the Midland WR-100 and First Alert WX-167, will not sound an audio alarm when the RWT is sent. In those cases where the audio alarm is blocked, an LED should light up and a visual message should appear acknowledging the RWT on the receiver display screen. This is consistent with the CEA 2009-A Public Alert standard which states that the audio RWT alarm may be disabled (blocked) by the manufacturer at the factory. NWR listeners concerned about receiving the Routine Weekly Test (RWT) should consult the owner’s manual to see how your receiver handles the test, and whether it allows them to turn the audio alarm for the RWT back on.

As an example: The following is the language from page 10 of the updated Midland WR-100 Owner’s Manual, which is available on the Midland Radio website:

"During a test, the yellow advisory LED will light up and the “Weekly Test” or “Monthly Test” message will be visible on the display. The radio will not sound an audible alert tone to avoid giving the impression of an actual alarm. The visual response to the test is confirmation that your radio is working properly. Please note: If your advisory light is on and continues to stay on, the radio will reset this function within 6 hours."
