WINDTONE HORNS
Each electric horn, before being passed out of the works, is adjusted to give its best
performance, and will give long periods of service without any attention. No adjustment is
required in service.
If for any reason the note is unsatisfactory do not attempt to dismantle the horn, but return
it to a Lucas Service Depot for examination.
