## BATTERY NOT CONNECTED INDICATIONS 

Battery not connected is indicated by FLASHING GREEN. In this mode charger will apply short pulses attempting to wake up deeply discharged batteries. 

## ERROR INDICATIONS 

2 red blinks: Battery is connected to charger with wrong polarity! 

3 red blinks: Charger output is shorted. Check output cable connection! 

4 red blinks: Battery voltage is low. Check battery status or voltage. 

5 red blinks: Safety timer has run out. Check battery status or capacity. LED off: Battery voltage is too high. Check battery voltage. 

## WAIT MODE INDICATIONS 

Yellow with 1 red blink: Battery temperature is too low (<0°C) Yellow with 2 red blink: Battery temperature is too high (>45°C)
