5.9 Activation of the Second Functions
The “S3” button activates the SL4 (Slide Switch 4) function, which means the user can manually
select the desired Flash Pattern (check the lightbar´s manual selection description) and activate
it once the “S3” button is pressed.
Pressing and holding the “S3” or the “Radio” buttons activate their second functions. In order to
activate them, their primary functions have to be inactive –this is a must. Either way, turning
back to their primary functions also need their second functions to be inactive.
The second function for the “S3” button activates the Siren´s WAIL Tone and also the Hands-
Free function. The second function for the “Radio” button activates the lightbar´s Dimmer. The
dimming only enters the active mode if the lightbar is connected in digital mode control.
Note that any Siren tone has higher priority over the Radio audio, so if you activate any of the
possible Siren tones with the Radio audio turned on, it will immediately cut the Radio audio and
produce the selected Siren tone until you stop it. Once you stop the Siren tone, the Radio audio
will NOT be activated automatically. You must turn it on again after turning off the Siren tone.
The same occurs with the second functions, like the dimmer and Hands Free. Once you have
activated one of these functions, any further generated Siren tone will quit them and wait until
you stop the Siren tone and then, if you want, activate again the previous active second function
of the buttons.
