Sonic Water Level Meter Maintenance
Batteries and power: The 6 AA batteries should be replaced at 6.5 V. Old batteries should be removed as soon as possible to prevent damage from leaking. To access the batteries, undo the screw from the back of the Control Unit and remove the battery cover and batteries. Ensure the new batteries are installed in the correct polarity, as labeled. Do not kink or damage the ribbon cable inside the Control Unit and be careful when reinstalling the battery cover. If the Control Unit is going to be stored for longer than a two month period, the 6 alkaline batteries should be removed to avoid any potential leakage.
Factory Reset: It is good practice to perform a Factory Reset before starting a new application, or at a minimum, once a month. A Factory Reset will default measurements to Metric.

| SYMPTOM | CAUSE | REMEDY |
| Will not power on / Display is blank | Contrast of the Control Unit is too low. | If the Probe makes the normal "popping" sound when powered on, but nothing is displayed, check the contrast of the Control Unit screen. You may be able to see the screen in a different lighting condition to adjust it. If this still does not work, a hard reset can be done by removing one of the AA batteries and waiting a few minutes before reinstalling. |
