Icom IC-2820H Basic Operations

These instructions are not a substitute for reading the manual 

NOTE: The IC-2820 is a dual receive radio with a left and right side and set of  keys and 

knobs.  The active side is identified by a MAIN icon in the top “left” corner of  the ac-

tive display.  When the instructions refer to MAIN key or knob, they refer to the active 

transceiver side and do not affect the inactive side until the inactive side is made active. 

To select the MAIN band, either press the DIAL knob on the side you wish to set ac-

tive. 

The IC-2820 has a magnetic attached face plate.  The connector cable may not be attached to the radio initially (use the short one, not 

the long extender cable).  Note that the six-pin end goes into the main unit and the four-pin end goes into the face plate.  The micro-

phone should already be attached and covered by a faceplate.
