Trek Lync Owner's Manual Supplement
Explanation of the system
The Lync lighting system uses a
rechargeable Lithium Ion battery to power a
headlight and two rear lights. Each light uses
a high-output LED (Light-Emitting Diode)
with a specially-designed reflector. This
combination creates a beam that is visible
from a wide angle.
Tools needed
The Lync includes a micro-USB cable for
recharging the battery. You will need a
2mm Allen key to adjust the angle of the
headlight.
Parts of the system
This section explains each component of
the Lync system (Figure 1): battery pack,
dock, headlight, rear lights, control panel
and wires.

Battery pack
The Lync system uses a Lithium Ion battery,
which is housed inside a small case- or
battery pack. The battery pack can easily
be removed from the bike for recharging.
Specifications:
• Lithium Ion battery
• 3100mAh 3.7V

Warning: Avoid mishandling of the battery
pack. These actions or others can cause
damage to or permanently disable the
battery pack:
• Recharging the battery when hot, such as
when sitting in direct sunlight
• Cleaning the battery pack under a high-
pressure tap
• Dropping the battery or exposing it to
sudden impact
• Immersing the battery pack in water
• Opening or puncturing the battery pack
• Short-circuiting the terminals
With a full charge, the battery should power
the Lync light system for about two hours
forty minutes at full power, or five hours at
low power. This time will vary according to
battery condition, temperature and other
environmental factors. When the battery
charge is at 10% or lower, a red indicator
light will flash on the upper portion of the
battery pack. The indicator light stops
flashing if the battery pack is removed from
the bike.
Travelling with Lithium Ion batteries
With a Lithium Ion battery, certain
restrictions on travel apply. If the terminals
are shorted on a Lithium Ion battery, it can
cause the battery to overheat and possibly
cause a fire. For this reason, airlines do not
allow Lithium Ion batteries in checked-in
baggage; you must put Lithium Ion batteries
in your carry-on luggage. Always check with
the carrier before travelling with Lithium Ion
batteries.
Extending the battery life
The Lync system battery is a long-life system.
The expected life of the battery is 300 to 400
charges. To extend the battery life, store it
in an almost-charged (not fully-charged)
condition at room temperature and avoid
extreme temperatures when recharging.
Storing the battery pack
When not using the battery pack for long
periods of time such as a week or more,
store it at room temperature in a dry place.
Avoid moisture, or extreme hot or cold.
Store the battery pack in a charged state.
Battery life will decrease if the battery pack
is stored in a fully-discharged condition.
