How to fix a blank screen on my Optimum Handhelds terminal?
- J
  justinhooverAug 21, 2025
  If your Optimum Handhelds terminal screen is blank, ensure the power supply or mains cable is correctly plugged into a working electrical wall socket and the switch is in the 'on' position. If using an extension cable, verify the fuse. For power supplies with a separate mains cable, ensure it's firmly connected. Hold the blue FUNCTION button for eight seconds. If it doesn't turn on, connect the power supply to the red socket labeled POWER or place it on a powered Charging Dock and repeat holding the blue FUNCTION button for eight seconds. If problems persist after checking these steps, please call the helpdesk.

Why does my Optimum Handhelds say 'LINE BUSY, WAIT'?

  Jeffery SimpsonAug 27, 2025
  The 'LINE BUSY, WAIT' message on your Optimum Handhelds indicates that the terminal is not detecting a normal dial tone on the telephone line. This could be because the line is in use, dead, or faulty. Also, check for faulty telephone cables or adaptors, ensure the terminal is properly connected, and verify the connection to the line isn't loose.

  If the Battery Module is not charging on your Optimum Handhelds (M4230/M4240), check that the power supply or mains cable is plugged into a working electrical wall socket and that any switch is in the on position. If an extension cable is being used, it may be fused, so check the fuse.
