Machine Charging
The TTB-1840 come with its own stand-alone charger.
Insert the charging lead required for your country into the charger.
Connect the charger to a suitable power supply.
The battery meter displays the charge level of the batteries; when fully charged,
all meter lights are illuminated (Fig 54).
As the machine is used and the batteries are discharged, the meter lights will go out from
top to bottom.
If the battery-charge level is allowed to discharge to the point that only one red light remains
illuminated, the operator should either replace or charge the battery.
Once mains power is connected the red charging indicator will illuminate.
To ensure a full charge, the battery should be left for a period of 6 hrs.
Once fully charged, disconnect the charging lead from both the power supply and the machine.
The battery charge state is shown by the light sequence on the front of the charger (g 54).
