MIC/EAR Jack
You may connect the supplied CT-60 Headset Cable
or the (optional) MH-44
this jack.
Never connect any Speaker/Microphone that
is not recommended by the manufacturer. Be-
cause these jack connections are unique, using a
Speaker/Microphone that is not specified by Vertex
Standard may damage the VXA-210. Accessories for
the Vertex Standard Amateur or Vertex Standard Com-
mercial radios will not work with the VXA-210.
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. Do not connect any wire to
this jack if that wire is connected directly to a 28-
Volt DC source. Connecting the VXA-210 directly to
a source which exceeds 15.0 Volts DC will result in
damage to the unit.
