|---|---|
| + | [* black] First we must check if this device would benefit from battery revival / recharging. Plug in a charger and make sure that the ear piece red lights illuminate. This will indicate that the onboard charger, regulator, and electronics are functioning. |
| + | [* black] However, if the unit is incapable of holding a charge, you should see that it will pull no current from the wal-wart charger. Not required, but you can see charging current from a USB power monitor such as the Klein Tool ET920. |
