Troubleshooting

If you suspect a malfunction, please check the following points. If
this does not resolve the problem, please contact a nearby dealer.
1. Power does not turn on
q Have the batteries have run down?
q When the batteries run low, the program/value display will
be dark. We recommend that you replace the batteries as
soon as possible. If batteries become unusable, remove them
immediately. Leaving drained batteries in the unit can cause
malfunctions (such as battery leakage). You should also remove
the batteries if you won't be using the StompLab for an extended
period of time.
q Make sure the batteries are inserted with the polarities (+, -)
in the correct orientation.
