Haven’t used the pair of HX471S radios in a couple of years. I installed new battery’s in each but they is no response when I turn them on. Any idea why that is?

If the Standard Horizon HX471S radios do not turn on after installing new batteries, possible reasons could include:

1. Battery voltage is too low.
2. Battery is not properly connected or seated.
3. Battery is not compatible or defective.
4. Microprocessor needs to be reset.

Check the battery connections and voltage, and if needed, perform a microprocessor reset.
