Goldzila… I know this is will be viewed as a smart ass question but is your Icon hooked up to a air or nitrox cylinder? The tank level will not display without being connected to a pressurized tank. If connected to an air or nitrox cylinder pressurized and it does not show tank level, does it show a pressure (PSI) above the tank level? The first thing I would do is update your firmware. You should be on version 4.2.2. If that does not help, then check the battery level for the transmitter, it may be weak and need a may need a battery change in the transmitter. Again this check will need connection to cylinder pressurized.
