To check or reset the Alarm Settings, push the "UP" button for 1 second then at the same time push the
"MODE" button for 5 seconds. The display will read CUSTOMER CAL.. Push the "MODE" button to
change the display to the next desired setting. To raise the setting, use the "UP" button, to lower use

TIMER MODES
NOTE: IN ALL MODES, THE UNIT WILL RETURN TO FLOAT IF THE EQUALIZE SWITCH IS PUSHED.
MODE 0
DISPLAY indicates P00
This is the standard timer mode. If the "EQUALIZE" switch is pushed the timer will switch the charger
into the equalize mode and the equalize "LED" will indicate. The timer will automatically return the
charger to the float mode when the equalize cycle is complete.
MODE 1
DISPLAY indicates P01
This mode of operation automatically starts an equalize cycle every 7 days after. The length of this cycle
is again determined by the timer setting. After the equalize period the timer will wait for another 7 days
and then restart.
MODE 2
DISPLAY indicates P02
This mode of operation automatically starts an equalize cycle every 14 days. The length of this cycle is
again determined by the timer setting. After the equalize period the timer will wait for another 14 days
and then restart.
MODE 3
DISPLAY indicates P03
This mode of operation automatically starts an equalize cycle every 30 days. The length of this cycle is
again determined by the timer setting. After the equalize period the timer will wait for another 30 days
and then restart.
MODE 4
DISPLAY indicates P04
This mode of operation automatically starts an equalize cycle when the DC voltage drops below the low
voltage setting for 30 seconds or longer. The battery voltage must rise approximately 8% above the low
voltage set point.
