Battery Charging; Replacing The Diaphragm - ADC Adtemp 658 Instructions For Use Manual

Battery Charging

When you see the low battery icon on the LCD display, you'll need to charge the unit. To
charge, make sure the unit is off, then open the USB cover and use the enclosed cable to
connect the scope to a power source. A full charge takes about 70 minutes.
When the unit is off and the battery is charging, the backlight display will be red. A blue
backlight while charging simply means the unit is on, and does not reflect when charging
is complete. To confirm that the unit is fully charged, remove the USB cable, power on,
and check the battery icon.
