All procedures can be split into these steps:

  1. Before picking up your screwdriver, check the OLED module. Connect it to a +12 V power supply; see the image in one of the steps below. The welcome screen should appear.
  2. Remove the top, bottom, and side panels of the FT-290 case.
  3. Remove all the front-panel knobs by simply pulling them off. Then unscrew the rotary controls located behind the knobs.
  4. Gently pull the front panel forward. The control board and the keyboard are held together by a couple of bolts, forming a sandwich-like assembly that needs to be separated.
  5. Once this is done, you will have access to the display unit. Disconnect it from the keyboard unit using the 9-pin connector.
  6. Desolder the red and black wires from the original—old and unattractive—display. These two wires provide a +12 V supply and power the S-meter backlight. We will use them to power the OLED module.
Original module connection
  1. Install the OLED module pcb in the place of the original pcb.
  2. Solder +12V from the step 5 to the OLED module. Please no mistakes here, +12V is going to Gray wire and the ground is the Orange wire (see photo). Starting from version v1.2 : +12v is Red and Ground is Black
  1. Reinstall everything back.
  2. Last important thing, make sure the switch on the back side of the rig is in LAMP position.
