5.3.1.1 TEST (UNIT CONNECTED TO MAINS)
The mains cord must be connected to a line receptacle with the correct
characteristics (check for the voltage), the "CHARGE" LED must be ON. A
charging process must be NOT already running (the LED indicators of the three
batteries must be OFF).
Press for at least one second the "TEST" button and release it: the
"BATTERY#1" and "TEST OK - FAULT" LED's will start to flash (green light)
while the test of the corresponding battery is carried-out. The "BATTERY#2" and
"BATTERY#3" will also start to flash in sequence. If the battery passes correctly
the test, the corresponding LED will stop to flash and will remain ON steady
(green), if otherwise any problem should be encountered, a RED light will turn ON
signaling a FAULT situation.
5.3.1.2 TEST (UNIT NOT CONNECTED TO MAINS)
The battery test can be also carried-out on the field when the Battery Pack is not
connected to the mains. The procedure (and the results too) are identical to the
ones previously described: it will be only necessary to HOLD DOWN THE
"TEST" KEY AS LONG AS THE TEST PROCEEDS

5.3.3 BATTERY TEST BEFORE CHARGING
The test before charging (or just to check the System before using it) must be
carried-out MANUALLY by the operator pressing the TEST key.
For every battery contained inside the Battery Pack, it will be first measured the
voltage OPEN-CIRCUIT: if this reading is below the table value, the
corresponding RED LED will turn ON and the test UNDER LOAD will NOT
take place (the battery needs charging ANYWAY). The battery is then loaded , the
voltage is measured again and the variation percentage with respect the first
OPEN-CIRCUIT reading is then calculated. If this percentage falls between the the
specified limits, the battery can be safely used being the internal resistance good and
