Power-Up Idle Time Limit: If no button is pressed within 10 minutes after the battery
charger is first powered up, the charger will automatically switch from tester to charger
if a battery is connected. In that case, the charger will be set to charge at the maintain
mode and gel cell battery type.
Testing After Charging: After the unit has been changed from tester to charger (by
selecting a charge rate), it remains a charger. To change the battery charger back to a
tester, press the CHARGE RATE button until all charge rate LEDs are off.
