Explanation of the Battery Low Message on a PSR540

The 'Battery Low' message can appear for various reasons:
  1. The six installed D-Cell batteries are worn out and need to be replaced. Check the batteries and install fresh ones if necessary.


  2. The wrong power supply is being used with the PSR540. Make sure that the correct power supply is being used. Click on "Dealer Locator" (found at the top of this page) to locate a dealer in your area.
