CTEK MUS 4.3 TEST&CHARGE Manuel page 9

TIPS
1. If the error lamp (2) immediately illuminates, the battery
is incorrectly connected. Unplug the charger, correct the
connections to the battery, and return to step 1.
2. If the lamp don't illuminate, this may be because the battery
is so discharged it cannot support the unit. If so, fully
charge the battery.
3. If mains mains voltage is detected, the MUS 4.3
TEST&CHARGE automatically enters Charging Mode. Press
the MODE-button (3) for two seconds to switch back to
Testing Mode, as signified by an illumination sequence in
lamp 4–6.
4. Start Power Test
OK (6) will illuminate at the start of the test, but may drop
down to BAD (4). Before discarding a battery, it's worth
charging it using the charger's Recond Mode and trying
the START POWER test again. Batteries failing this test in
warm weather will almost certainly fail completely when
temperatures drop.
