  If your Alinco Transceiver powers on but the display remains blank, there are several potential causes: * The polarities of the power connection might be reversed. Ensure the red lead and black lead of the DC power cable are correctly connected to the positive and negative terminals, respectively. * The fuse could be blown. Inspect the fuse, address the reason it blew, and replace it with a new fuse of the same rating. * The ACC power supply might be connected but turned off. Verify that the ACC power supply is switched on.

  If you're not getting any sound from your Alinco Transceiver's speaker and the unit isn't receiving, consider these possibilities: * The volume knob may be turned too far counter-clockwise. Adjust the volume knob to an audible level. * The squelch might be muted. Decrease the squelch level. * Tone or DCS squelch could be active. Deactivate tone or DCS squelch. * The PTT key on the microphone may be pressed, causing transmission. Release the PTT key. * An external speaker might be connected. Disconnect the jack from the external speaker terminal.
