IMPORTANT !
The RLS Series Siren has two distinct modes of operation. These are Hit-N-Go mode and SCROLL
mode. The desired mode of operation can be selected via the amplifier rear panel slide switch. Each
mode will affect the siren operation as described below. The Hit-N-Go mode should be most familiar to
existing
users.
The configuration of the SirenLock and Park Kill features
will, in some cases, prevent the siren from producing
siren tones. The siren will not produce tones when the
vehicle is in "PARK" if the PKILL feature has been
connected and the PKILL enable switch is ON. If the
Siren Lock feature is enabled (lighting Level-2 or 3), the
siren will not produce tones until the appropriate lighting
level is selected by the progressive warning light switch.
To test the siren tones the vehicle must not be in "PARK".
The following assumes that PKILL has not been activated
and that the progressive warning light switch is set to the
appropriate position.
