charger cannot deliver this current at the voltage set on the display. At this voltage level, the charger will
be running at maximum power. However, this current could be delivered at lower voltage depending on
the power output of the charger.
• Start of the charge:
To start the mode, press the START/STOP button.
1
If the AUTO-DETECT function is active, charging
will start automatically after 5 seconds if a
battery is present.
2 During the mode, your Explorer 120/130 indicates the battery
voltage and the current delivered by the charger.
3 Press the START/STOP button to stop the mode.
Precautions :
When starting the mode, a current displayed above 10 A means that your battery is discharged. The device
will start charging automatically Check that there is no electrical consumer on the vehicle. Wait until the
current supplied drops below 10 A before starting any action on the vehicle (use of the vehicle's electrical
accessories, diagnostic operation, etc.).

• «No battery» function (not recommended):
This function allows you to use the SHOWROOM power mode when there is no
battery. To do this, press the START/STOP button for 3 seconds. The «No battery
mode» indication is displayed for 3 seconds before forcing the power supply.
It is strongly recommended not to use the «no battery» function if a battery is present.
This function disables the «Integrated charging» function, as well as some of the protections such
as abnormal undervoltage protection or disconnection detection.
In this configuration, reverse polarity can damage the vehicle electronics.
• «Integrated charging» function:
The SHOWROOM mode (outside of the «no battery» function) incorporates an automatic charging algorithm
adapted to all types of batteries (lead and lithium), in order to guarantee an optimal charge level for de-
monstration vehicles. This function is perfectly compatible with the presence of consumers on the battery.
