for two minutes.

magnet with the mark

The Automatic Inter-3 returns to 1st gear when the bicycle stops.
When riding the bicycle, a beep will be heard before a gear shift
occurs to notify the rider that a gear shift is about to take place.
When the battery is nearly spent, a long beep (about three seconds),
and the gear mechanism will return to 1st gear. If you continue to
use the unit with spent batteries still inserted, the unit will not operate
correctly, and the batteries may leak. Replace spent batteries with
new alkali batteries as soon as possible.
Some types of batteries may become spent more quickly than usual
when used in cold temperature conditions.

The Automatic Inter-3 is an automatic gear shifting system
in which the shifting points are determined by the speed of
the bicycle (the rotating speed of the wheels). Because of
this, gear shifting can occur independently of the rider's
intentions, and so shocks may be felt during shifting. Make
sure that you understand and become accustomed to these
shifting characteristics before using the system extensively.
Make sure that the bicycle has been secured in a stable
position before replacing the batteries or adjusting the bell
crank or the magnet. If the bicycle is not stable, it may
cause injury, or the main unit may not operate correctly.
CAUTION
Cable adjustment bolt
Turn the cable adjustment bolt of the bell crank counterclockwise so
that the end of the hub axle and the red line on the push rod are
aligned.
Magnet holder
Align the red line with
the end of the hub axle
Use a Phillips screwdriver to loosen the two cover fixing screws,
and then remove the
main unit cover.
