TO CONTROL FAN SPEED
ViVi
All
®
helmets provide the user with two options to control the fan speed,
manual and automatic. To manually change the fan speed the user will pre-
form the following:
1. From a natural starting position the user should tilt there head straight back.
2. Once a "beep" sound is heard, the fan speed has changed.
3. The user returns there head to the starting position.
The "beep" sound will correspond with the speed of the fan. A low pitch sound will
be heard for the low speed, two "beeps" will be heard for the middle speed and a
higher pitch sound will be heard for the fastest fan speed.
The second option for the fan speed control is an automatic system built into
all
ViVi
®
helmets. When the helmet is powered on it starts in automatic mode;
it can also be placed in automatic mode using the head gestures to reach the
middle speed (two "beeps"). The automatic mode of the helmet will adjust the
speed of the fan based on the activity of the user. As the user becomes more
physically active, the fan will automatically begin to speed up; as activity levels
begin to lower the fan speed will also lower.
NOTES:
• The user can manually switch out of automatic mode at any time using the
previously described head motion.
• Familiarization with the fan speed control system is recommended to
ensure user comfort during operation.

• DO NOT doff the helmet together with the hood/toga and pull on the hood
to remove it from the helmet. This might damage the helmet.

cord in a counter clockwise direction.
2. Unplug the power cord from the battery, the fans will automatically turn off .
3. Loosen the headband adjustment knob and remove the helmet from your
