Why does my Tru-Test Scanner switch off unexpectedly?
- JJennifer NielsenSep 1, 2025
If your Tru-Test Scanner has switched off unexpectedly, it is likely due to the auto power off feature, which is enabled by default. To change this, use the keypad to go to Home, then Settings, then General, then Auto Off, and press the ‘Scan/Select’ button to disable the auto power down or select a different auto power off period. Alternatively, the battery may be too low, so recharge it using the USB power adapter.
