CAUTION:
Risk of injury - Only use the battery charger supplied to charge
batteries.
As the IMPULSE S (6 A) charger aligns the charge curve with the AGM batteries' charge
level, you can recharge your wheelchair after each use. This avoids any aggressive battery
charging and the "memory effect".
Recharge the wheelchair, at the latest, when the charge indicator on the steering unit goes
into the red zone. If, despite this, you continue driving, eventually only the last red diode
lights up and flashes continually, indicating that the batteries are nearly flat. If you disregard
this warning signal, too, an error message will shortly appear indicating that the batteries can
no longer provide power for driving. The batteries should therefore be charged before these
error messages appear, using the supplied battery charger IMPULSE S (6 A). Avoid the
batteries becoming drained, in any case.

FIRST USE
First put the plug into the wall socket. After an LED combination has lit up, the charger
switches to STANDBY. Both LEDs (green and yellow) are active.
Next, connect the charger cable with the three-pin plug to the loader socket on the electric
wheelchair's operator control. Once connected to the batteries, the charger automatically
begins charging. Now only the yellow LED is active.
When charging is complete, the yellow LED goes out and the green LED comes on. Now
remove the charger cable from the operator control. The charger switches back to STAND-
BY mode (yellow and green LEDs active).
If the charger cable is not removed, a tiny current will keep the batteries topped up (trickle
charging).
If you decide not to use your electric wheelchair for an appreciable period, you must
nevertheless recharge it regularly to keep it in a running condition ready for immediate use.
The manufacturer accepts no liability for damage caused by improper charging.
For further information, please refer to the user instructions provided with the charger.
