Power Supplies (Overview)
Focus can be powered in four different ways – the battery, AC power, DC power, or an optional AirBelt. The Focus power
supply functions both as an AC power supply and a DC power supply.
(Refer to
Connecting to Focus’s Power Inlet
section for
specific instructions regarding the connection of optional
power sources.)
Battery: Two rechargeable batteries are supplied with Focus. Each battery, when fully charged, supplies power to the
Focus unit for up to 1 ½
hours. An audible alarm sounds when the battery power is getting low. The alarm is discussed in
the Audible Alarm and Indicator Lights section of this manual. The 25% capacity LED will blink every ½ second to
indicate a low state of charge when the button is pressed.
During this condition, change to another battery or alternate power source.
Battery Charging (Battery Charging section):
To charge the battery, connect the battery to either the power supply and
a 100-240 volt, 50/60 Hz AC power outlet, or connect the power supply to a DC power outlet in an automobile (boat,
motor home, etc.). A discharged battery requires approximately four hours to fully charge. It is recommended to
recharge the battery, even if only partially depleted, as often as possible.
Universal Power Supply
The AC power supply side of the universal power supply, allows the Focus unit to connect to a 100-240 volt, 50/60 Hz
outlet. The power supply converts 100-240 volt AC to a DC voltage for the Focus unit to operate while recharging the
Focus battery simultaneously.
The DC power inlet on the universal power supply, allows the Focus unit to connect to a motor vehicle’s 12-Volt DC
outlet for the Focus unit to operate while recharging Focus’s battery simultaneously.
Optional AirBelt: Focus can also be powered with AirBelt. AirBelt can be worn around the waist. When fully charged,
the battery supplies power to Focus for up to 4 hours. AirBelt connects to the Focus unit’s power inlet. It can be recharged
by connecting it only to the AirBelt AC power supply.
