SHOWROOM MODE
On a stationary vehicle, the GYSFLASH supplies up to 40A to test high-energy consumers (engine fan, window regulator, electronic
suspension, etc...) by supplying a steady voltage adjustable:
- 12V to 14.8V
Volatage adjustment:
It is possible to adjust the voltage in steps of 0.1V according to manufacturer's specifications.

Start without battery (not recommended)
It is possible to supply power to the vehicle without a battery by pushing the START/STOP key for 3 secondes. The screen will
display "no battery" for 1 second before starting to supply the vehicle.
Warning: polarity reversal can damage vehicle electronics.
Precaution :
If the screen displays a current higher than 10A, it indicates the battery is discharged. The device will start charging automatically.
Check all electrical consumers are switched off on the vehicle. Wait until the current falls below 10A before using any electical func-
tions of the car.
CHANGE BATTERY MODE (OPTIONAL)
The GYSFLASH will maintain a stabilised power supply to the vehicle during battery replacement to preserve memory settings. By
default this mode is inactive and doesn't appear in the mode list. It can be activated via the Advanced menu (see page 19).
Start up :
• Connect :
1 : Red clamp to the (+) of the battery / battery terminal, in such a way that the battery can be changed without disconnecting
the clamp.
2 : Black clamp to the vehicle chassis or earth.
• Press the START/STOP key to start the mode.
• During use, the current consumed and the instanta-
neous voltage are displayed.
• When changing the battery ensure the polarity is
correct.While exchanging the batteries, be careful
not to disconnect the charger clamps to avoid loss of
electronic data.
aWarning: polarity reversal can damage the vehicle electronics.
POWER SUPPLY MODE (OPTIONAL)
This mode is intended for expert users only. This mode enables the charger to be used as a stabilised power supply, with regulated
voltage and adjustable maximum current. By default this mode is inactive and doesn't appear in the mode list. It can be activated
via the Advanced menu (see page 19).
Adjustment of the voltage regulation and current limitation :
The voltage regulation can be adjusted from 2V to 30V and the maximum current from 2A to 40A. For an adjustable voltage above
16V, the maximum current can be set up to 20A:
