Charging The Battery
Always fully charge the battery before using the instrument. The
instrument’s Li-ion battery is charged by placing the instrument in its
cradle. (The battery can also be charged by placing the instrument in
an AutoRAE 2 Cradle.) Contacts on the bottom of the instrument
meet the cradle’s contacts, transferring power without other
connections.
Note: Before setting the instrument 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 instrument:
1. Plug the AC/DC adapter’s barrel connector into the
instrument’s cradle.
2. Plug the AC/DC adapter into the wall outlet.
3. Place the instrument into the cradle, press down, and lean it
back. It locks in place and the LED in the cradle glow
The instrument begins charging automatically. The “Primary” LED in
the cradle blinks green to indicate charging. During charging, the
diagonal lines in the battery icon on the instrument’s display are
animated and you see the message “Charging...”
When the instrument’s battery is fully charged, the battery icon
is no longer animated and shows a full battery. The message
“Fully charged!” is shown. The cradle’s LED glows
continuously green.
