Designed for models:

240, 250, 250C, 260, 270, 270B, 300, 350, 350C, 400, 500, 500CX, 600, 700S, 700CX, and 750CW.
Simply turn a trimpot until the IF frequency of your radio is displayed.

For those with a 5.1735MHz IF, a switch on the back decides 80 and 40  or  20, 15 and 10 meters

For the other models, with 5.5 MHz IF, the switch decides Normal or Reversed SSB to match the setting of the switch on the radio.

For the 250 and 250C the vfo reading is multiplied by 3 and added to the IF.  The switch does nothing.  Resolution is 100Hz instead of 10Hz.

For many of these radios the VFO signal is available on the accessory socket on the back panel.
