2 Charging The QRAE II Battery
Always fully charge the battery before using the QRAE II. The QRAE II’s Li-ion battery
is charged by placing the QRAE II in its cradle. Contacts on the bottom of the QRAE II
meet the cradle’s contacts, transferring power without other connections.
Note:
Before setting the QRAE II into its charging cradle, visually inspect the contacts to
make sure they are clean. If they are not, wipe them with a soft cloth. Do not use solvents
or cleaners.
Follow this procedure to charge the QRAE II:
1. Plug the AC/DC adapter into the QRAE II’s cradle.
2. Plug the AC/DC adapter into the wall outlet.
3. Place the QRAE II into the cradle and press down until the LED glows.
The QRAE II begins charging automatically. The LED in the cradle should glow red to
indicate charging. During charging, the display shows this message:
Charging...
At the same time, the voltage is indicated in the QRAE II’s display, as well as an
electrical plug icon is shown next to the battery:
When the QRAE II’s battery is fully charged, the message “Fully Charged!” is shown in
the display, and the icons for the electrical plug and the battery are shown.
When charging is complete, the LED in the cradle glows green.
