Lights
The headlight of the Lync system is in the
head tube (Figure 7). It can be switched to
Off, High or Low. There are two rear lights:
one in each of the rear dropouts. The rear
lights can be switched to On, Flash, or Off.
The Lync system lights are maintenance
free; because they use LEDs, there are
no bulbs to burn out. If your lights do not
work (but your battery pack is charged
and connected), take your bicycle to your
dealer for service.
The headlight on the Lync is a "To See"
system, intended to illuminate the road
ahead of you. This system provides light in
a focused beam. It does not provide the
wide, dispersed beam of a 'to be seen'
light. For any amount of night riding, you
should add a 'to be seen' light to your
bicycle.
The angle of the headlight can be adjusted
with a 2mm Allen key. The adjusting screw is
located just above the light (Figure 7) and
is accessible through the cover. Do not turn
the screw past the stop; overtightening can
damage the bracket.

CAUTION: If left switched on for
an
extended
especially if the bike is stationary,
the headlight may become hot.

Wires
The wires run inside the frame. On any
electrical system, the integrity of the
wires and connections are critical for the
system to function. The connections on the
Lync system are a high-quality, positive-
engagement type and resistant to water.
Avoid contaminating the wires or
connections with excessive moisture (such
as immersion or power washing the bike),
which could result in a short circuit, causing
the lights on the Lync to malfunction.
