EXT DC
Jack
When an external 12-Volt DC power source is avail-
able, you may connect the (optional)
E-DC-5B
Ex-
ternal DC Cable here.
1) Do not allow the
FTA-310
to become
submerged in water while the rubber cover
is removed.
2) Do not connect any wire to this jack if that wire
is connected directly to a 28-Volt DC source. Con-
necting the
FTA-310
directly to a source which
exceeds 15.0 Volts DC will result in damage to the
unit, and this type of damage is not covered by the
Limited warranty on this product.
