CHAPTER 8
Servicing the Pathfinder
Federal Signal recommends that the siren be returned to your local distributor or Federal Signal for
service. External components such as cabling are available as replacement parts (see Table 8.1).
Except for the slide switch in the siren, there are no other user-serviceable parts within the unit. After
servicing the system, test it to ensure that it is operating properly.
Replacing the Slide Switch
The slide switch can be removed from the siren without removing the siren from the vehicle in most
installations.
STATIC SENSITIVE DEVICE — The circuitry of the control head can be damaged
by electrostatic discharge. Follow anti-static procedures removing the slide
switch.
