Re-program the trickle speed to a slower speed.
1.) Turn unit on and let it stabilize.
2.) Press the "0" button (unit should beep once)
3.) Press the CAL button once.
4.) A number between 0.0 and 25.5 will appear
5.) Press CAL button repeatedly until a number between 0.5 and 1.0 appears. The normal trickle speed is 0.6.
NOTE: pressing CAL will increase the number in 0.1 increments until it reaches 25.5. However, if you continue to press CAL the number will cycle back to 0.1. This is usually the fastest way to reset the trickle speed.
NOTE: Pressing UNIT will decrease the number in 0.1 increments.
6.) After reaching the new trickle speed, press BACK/CANCEL to store trickle speed and return to normal operation.
NOTE: The new trickle speed should be permanently stored even if the Auto Charge is turned off.
