The above event codes notated with an asterick have a default setting to not sound the
siren but ONLY display a message and light the yellow LED when received. This is not an
indication the radio is not working properly, but the intended functionality. All other alerts are
defaulted to sound the siren and display the alert message. You may reprogram the default
setting of the above advisories and most other alerts by following the instructions on page 9.
