NOTICE:
Before touching anything inside the carriage
assembly, ground yourself by touching an unpainted
metal surface on the unit such as an exposed bolt,
or one of the mounting screws on the
electrical panel. While you work, periodically touch
an unpainted metal surface to dissipate any static
electricity that could harm internal compo
nents.
CIRCUIT BOARD DIAGNOSTICS
Also located on the 4-ganged DIP switch are switches #3 Installation and #4
Coast Delay. The coast delay option (Switch #4) has been provided in cases of
interference which may cause intermittent operation. The normal setting is 600
mSec. of coast. Should the unit lose the remote call/send signal, this can be
increased to 900 mSec. by moving Switch #4 to the `ON’ position.
