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 taillights: one
in each of the rear dropouts. The taillights
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 hex wrench. The adjusting
screw is located just above the light (Figure
7) and accessible through the cover. Do not
turn the screw past the stop; overtightening
can damage the bracket.

CAUTION: If left On for an
extended period of time, especially
if the bike is stationary, the
headlight may be hot.

Control panel
The control panel is located under the top
tube of the frame, near the head tube
(Figure 8). It has two buttons; the front
button is for the headlight, the rear button
is for the taillights. They control the light
functions.
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 can lead to a short circuit that could
cause the lights on the Lync to malfunction.
