Optional AirBelt
Optionally, you may also have an AirBelt for extended use of Focus.
The optional AirBelt (Figure 14), can power the Focus unit for up to 4 hours.
Before using AirBelt, check that it is sufficiently charged. It requires
approximately 3½ hours to completely charge. AirBelt is equipped with a
battery gauge/indicator to indicate the level of battery charge (25-100%). To
check the level of charge, press the button on the AirBelt keypad. The
battery gauge/indicator(s) illuminate to indicate the level of battery charge
(25-100%). Connect the interface cable (Figure 15) into the AirBelt, then
plug the other end of the interface cable into the Focus, as shown in Figure
16. For correct orientation of the connector, see Connecting to the Focus
Power Inlet section.
