● good (green),

● weak (yellow),

● almost empty (red).

If the display shows red, an additional shrill alarm signal will sound to make the driver aware of the critical

battery charge level.

PLEASE NOTE:

The B

doesn't just monitor the current battery level by means of the applied voltage but also has the

attwatch

patented technology of „determining the discharge curve" to show the actual battery level. For that reason the

headlights have to be turned on when the battery level is checked, so that the battery is undergoing a discharge

process. Here the voltage displayed on the B

shows the battery's decrease in voltage that is caused by

attwatch

the drain. That is the foundation for the determination of the actual battery level.

Battery status okay (illustr. 4)

If the voltage is more than 11.5 Volts, the B

shows the green OK symbol – for the user, this means that

attwatch

the battery level is okay and the vehicle can be started without any concerns.

Battery status weak (Illustr. 5)

The display of the yellow B

symbol ("LOW") appears when the voltage is between 11.3 – 11.4 volts and

attwatch

shows that the battery capacity is low. Although the vehicle can be started, we recommend that it be driven for

approx. 30 minutes so that the battery can be recharged again through the generator. When the yellow symbol

is displayed, we recommend that the engine is not idling for a long time; instead you should begin driving im-

mediately if possible. If the engine is idling for a longer period, the battery is discharged further and may even

lead to a complete discharge depending on the battery level. Then the vehicle would no longer be capable of

being driven.

Battery almost empty or empty (display with alarm signal) (illustr. 6)

If the red X symbol is displayed, accompanied by a shrill alarm signal – for a displayed voltage of less than 11.2

volts – the B

signals that the battery is now almost empty. In that case the user has to drive for much

attwatch

more than 30 minutes to properly recharge the battery again.

But if the user checks his car battery with the B

on two or more subsequent days and the red X symbol

attwatch

appears every time, this means that the car battery has reached the end of its life cycle or - if the battery is still

relatively new - that there is a defect and that it can no longer be charged with the generator. In that case we

urgently recommend that the user have his battery checked or replaced at a car repair shop.

PLEASE NOTE:

After you have finished checking the battery status, turn off the headlights and start the engine. With nearly all

vehicle models, the red X symbol will flash for a fraction of a second and a short beep will sound when the engine

is started. This is caused by the high strain on the battery at the moment when the engine is started; it is quite

normal and not an indication of any defect.

5. Control of the regulator function

Regulator function is flawless (illustr. 7)

When the engine is switched on, the B

indicates a flawless functionality of the vehicle's energy system

attwatch

with a green display of the „Chg." symbol. Here the green OK symbol shows the intact condition of the charging

system. If different electricity consumers are turned on before the vehicle is driven – e.g. air conditioning, hi-fi

system, etc. - the green "Chg." display turns off. This has no negative significance for the vehicle's energy system

but only shows that the B

constantly monitors the energy system of the vehicle and registers every

attwatch

change. (Model B

1000: the flawless function of the vehicle's energy system is shown only by the green

attwatch

OK symbol; the "Chg." symbol does not glow in green.)

The same applies after the vehicle starts driving. During a slow drive (below 50 km/h) and if several electricity

consumers are switched on, the green "Chg." symbol will be turned off here too. In this case there is also no

adverse effect on the vehicle's energy system.

The following applies for the user of the B

in general: as long as only green symbols are displayed,
