3.1.4.1 To charge the Focus battery while using the power supply with Focus
1a) Using AC Power: Follow the instructions in the Connecting Focus to AC electrical power
section.
1b) Using DC Power: Follow the instructions in the Connecting Focus with the Battery section.
2) Connect the battery cord without the on / off switch into the power supply outlet marked DC
OUT To Battery. Connect the other end to the battery.
Note: The battery is charging whenever the unit operates on AC or DC power.
• The Focus battery will completely recharge from its fully depleted state in
approximately four hours, whether or not the unit is in use on AC or DC power.
• While charging a fully discharged battery, the LED will continue to blink until 25%
capacity is reached. The LED will then turn solid.
• Each of the four LEDs, 25% -100%, will blink as stated above, then turn solid when
they reach their capacity.
• When all LEDs illuminate solid, the battery is fully charged and the LEDs will remain
solid for a period of time, then all four LEDs will turn off .
• Wherever storing Focus battery for an extended period of time, ensure that the battery state of
charge (SOC) is not depleted or stored at 100%. Both these conditions can result in
unrecoverable capacity loss. The recommended SOC is 25% to 50% for long-term storage.
The recommended storage temperature is 23
o C +/- 2 o C.
The Battery can be recharged from the power
supply
while using Focus AC or DC power.
