Side car helmet connections
Please consider that, when using 3 or 4 helmets, the
power-on automatic is only activated with the driver’s and pillion driver’s helmet
Important advice for the sound volume
Absolutely do not use a higher volume than necessary!
Your hearing can be damaged by a volume that is too high.
Additionally, the driver’s concentration
on the traffic is not ensured any more.

The power amplifier has a overcharge switch-off for the loudspeakers. When the
volume is too loud, the amplifier exit will temporarily be shut down. In such a case
it is essential to reduce the volume, a damage of the loudspeakers might
otherwise be possible! Especially when using ear protection plugs the volume is
adjusted at a much higher level as usually.
