Charge the Battery
IMPORTANT: Before installing the battery for the first time, charge the battery for at least an hour and a half to ensure
a fully charged unit. A fully charged battery lasts approximately 40 hours between charges.
The battery charger has an LED, shown in Figure 23, that displays two (2) color states:
Green LED – The charger is on.
Red LED – The battery is being charged. Once the battery is done charging, the green LED appears.
NOTE: If the battery is damaged and not able to charge, the red LED does not display.
The power module for the battery charger comes with the US connection adaptor as standard. There are three (3) optional
connection adapters (Euro, UK, and Australian), known as the world adapters.
To change the connection adapter for the power module, do the following:
1. While pressing the adapter lock, turn the adapter counter-clockwise to release the adapter.
2. Replace the current adapter with the desired power module adapter.
3. Turn the new adapter clockwise to lock it in place.
