LI-282 Rev. 2.2 September 2019
The voltage reading that the Activator 282 uses to regulate the battery charge is
the same as the displayed voltage. If the voltmeter reading is more than ±0.20
Volts different from the display, it may be necessary to calibrate or repair the
Activator 282. This is best done by the distributor or factory.

Verifying Fan Operation
It is recommended this be performed each time the unit is switched on.
It does not matter if the Activator 282 is connected to a battery. Connect AC
power and check for air movement through the top fan vent holes. Use a
flashlight or strong room light to verify that the fan is rotating. Listen for any
ticking or grinding sounds that indicate a bad fan bearing.
The fan is very small, and the airflow is not strong. That is normal.
A bad fan can be replaced by the distributor or by the factory.
