Battery protection system

The device is equipped with a battery protection sys-
tem. This system automatically cuts off power to the
motor to extend battery life.
If the remaining battery capacity is too low, the device
will not operate. When you turn the device on, the motor
will run again, but stops soon. In this situation, remove
and recharge the battery cartridge.
Air flow
Air flow inside the jacket is shown below.
► Fig.22
For the jacket with the hood, wear the hood over your
helmet. The air from the fan goes through the helmet
and cools your head.

Battery pocket
NOTE: Some jacket/vest does not have the battery
pocket. Refer to the section for the specifications for
