Charging the Battery and Using the AC Adapter

Recharge the battery as soon as "LOW BATTERY"
appears on the display.
The battery symbols on the display show the status of the
battery:
++ The battery is in "Fast Charge" mode.
The ac adapter/charger is connected and the
battery is charging. When the battery is below
95 % of its charge, the Particle Counter uses
"Fast Charge" mode to bring the battery back up
to 95 %.
+
The battery is in "Trickle Charge" mode. Once
95 % of the charge is attained, the Particle
Counter switches to "Trickle Charge" mode to
charge the remaining 5 % of the battery.
The battery is fully charged.
The battery is partially charged.
The ac adapter is used to recharge the battery as well as
power the Particle Counter. This feature allows the
counter to be used while the battery is charging.
To connect the ac adapter/charger:
1. Attach the power cord to the end of the charger.

2. Plug the charger into the 12V jack on the base of the
Particle Counter.
3. Plug the ac adapter into an ac outlet. The Particle
Counter will take two hours to fully charge.
If the Particle Counter is powered off during
charging (Trickle Charge mode), the battery will
require up to 18 hours for a full charge. To
charge the battery in 2 hours, the Particle
Counter must be turned on while charging (Fast
Charge mode).
If the Particle Counter is charged while powered
off (Trickle Charge mode) the battery symbol in
the display will not update to show the actual
charge status until the Particle Counter is turned
on with the charger plugged in for approximately
five minutes.
