EXT DC
Jack
When an external 12-Volt DC power source is avail-
able, you may connect the (optional)

Ex-
ternal DC Cable here.
1) Do not connect any wire to this jack if that
wire is connected directly to a 28-Volt DC
source. Connecting the
VXA-220
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.
2) Do not allow the
VXA-220
to become submerged
in water while the rubber cap over the
EXT DC
jack
is removed.
