Choosing your settings
Failure to correctly set the system voltage (VOLT) and select the
correct program (PROG) for your battery may result in damage
to the battery or connected equipment. Follow this procedure:
1. Set the Time
a. Short-push until the display shows “SET”.
b. Long-push once and the display will show “TIME”.
c. Long-push again, and the time will start flashing. (Note that
the time is displayed in hours and tenths of hours. For
example, “6.5” means 6:30am, and “13.1” means 1:06pm.)
d. Short-push until the time shown is correct. If you reach 23.9
(11.54pm), it will cycle back to 0.0 (midnight).
e. When the time shown is correct, long-push to set it.
Note: time setting does not affect battery charging.
REVERSE & FAST FORWARD
If you overshoot the setting you want and need to go back, you can
use reverse. Do a long push. The number stops flashing. Do another
long push. The number starts flashing again but this time goes down.
More than 5 quick pushes will start the fast forward mode.
To return to normal mode, stop pushing for 1 second.
2. Set the System Voltage (! Important)
a. Short-push to move from “TIME” to “VOLT”.
b. Long-push and the voltage will start flashing.
c. Short-push until the voltage is correct for your battery. If
you pass 48V, it will cycle back to 12V.
