There is no power on the device. How can I do?


Try the following:

  • Replace old batteries with new ones.
  • Make sure the batteries are aligned with the polarity in the battery compartment correctly.
  • If you use an AC adapter, make sure the AC adapter is connected properly.
  • Make sure the HOLD switch is switched to the OFF position. (Depending on models, the HOLD switch is usually located on the bottom of the unit.)
