To recharge with the in-car DC charging adaptor.
Note: This method of charging is not automatically protected
against overcharging and must be constantly monitored by
the user as described below. IMPORTANT: Ensure that the
vehicle's accessory socket is rated at 12V.
3.6.1 ensure that the power clamps are in the designated holsters.
3.6.2 With the vehicle's engine running, plug the in-car dc charging
cable into the charge input socket on the front of the roadstart
(refer to 4 in fig.1) and then the other end into the vehicle's
accessory socket. the unit will be charged by the alternator. It
will be necessary to press the test button once every hour to
monitor the level of charge. When all of the red lights are
illuminated plus the green 'charged' light, continue to charge for
another 1 to 2 hours and then disconnect the unit from the
vehicle lighter socket to avoid overcharging which could
damage the unit.
Note: If the amber charging light begins to flash or the battery
becomes completely flat, then a 72 hour charge will be
necessary using the Ac power adaptor.
4. OPERATION
WARNING! YOU MUST FOLLOW THE SAFETY INSTRUCTIONS
Preparation and precautions
WARNING! ENSURE THAT YOU ARE FAMILIAR WITH THE VEHICLE'S BATTERY VOLTAGE AND
THE VOLTAGE PRESENT IN THE VEHICLES ACCESSORY POWER SOCKET (CIGARETTE
LIGHTER SOCKET). THESE SHOULD BE EITHER 12V OR 24V DC
Apply the vehicle hand brake and place in neutral gear (or "Park" if automatic transmission).
turn ignition and electrical accessories off. NOTE: some vehicle ignition systems must be turned to "Accessory" to activate the
accessory socket.
use in a well ventilated area and wear protective eye shields and clothing.
NOTE: A defective battery may not accept a charge from the portable power source.

Roadstart Safety Features
this roadstart unit is fitted with a number of safety devices which ensure that the operator does not damage the vehicles battery or the
roadstart unit. the roadstart is fitted with an override switch which should be used only in a pre-described set of circumstances. In the
event of misconnection, the safety devices will cut power to the clamps and will also sound a buzzer and flash the led charging lights.
the circumstances of operation are as follows:

the roadstart determines the battery voltage of the circuit to which it is attached by reading the voltage in the vehicle's system. In the event
that the roadstart is correctly connected to a 24V volt vehicle with a badly discharged battery (below 16V), it is possible that the roadstart
may interpret the vehicle's battery voltage as 12V causing the safety function to prevent the unit from working properly. using the same format
