If voltage selection in STEP 1 matches the expected battery voltage and there are no connection errors as described in
STEP 2, then fully automatic operation starts from STEP 3.

Confirms AC power supply to the charger and selected battery
voltage.
Changing voltage selection: Disconnect charger from battery. Push and
release the pushbutton switch. The mode selection changes when the
2
button is released. SAVE (#3), CHARGE (#4) and TEST (#5 & 6) LEDs flash
twice to confirm selection is in memory, confirming your battery can now
be connected.
LED #2 REVERSE POLARITY: Lights when the battery connections are
incorrect. The charger is electronically protected so no damage will result,
and the output will remain disabled until the connections are corrected.

VOLTAGE SAFETY CHECK:
6V (#1a) is flashing / blinking: 6V is selected and a battery with
voltage exceeding 8V is connected.
Connected battery may be 12V. Action: Disconnect battery, select 12V.
For an overcharged 6V battery: When battery voltage reduces below 8V the
charger will automatically activate. IMPORTANT: an overcharged battery
may have lost electrolyte. In the case of batteries with filler caps on each
cell, disconnect the battery from the charger, check the level of the
electrolyte and if necessary, top up the cells (with distilled water, NOT
acid), then reconnect.
12V (#1b) is flashing / blinking: 12V (#1b) selected and a battery with
voltage below 8V is connected:
The connected battery may be 6V or it may be a deep discharged 12V
battery.
Action: Physically check battery. If nominal voltage is 6V, disconnect
2
battery and select 6V.
If nominal voltage is 12V, push and hold pushbutton switch. After 3
seconds program will proceed to STEP 3.
The SAVE mode engages if the battery state of charge was less than
50% or the battery was diagnosed as sulphated (as tested in STEP 3).

Charge time: Minimum 15 minutes, maximum 2 hours.
A reconditioning charge is applied; current is delivered in pulses to prepare
the battery to accept normal charge.
READ the section VERY FLAT NEGLECTED BATTERIES.
The CHARGE mode engages if the battery state of charge was 50% or
higher (as tested in STEP 3) or once the battery has been sufficiently
