“To See” light system

The lighng system on the Lync is a “To See”

system, intended to work as a head light

in low-visibility situaons. The high-output

LEDs (Light Eming Diodes) provide a bright

550 lumens headlight in a focused paern to

illuminate the road ahead. The taillights (two)

are 3 lumens each.

This type of light meets lighng requirements

in most areas. Check with local authories for

the requirements in your area.

The other type of light system, “To Be Seen”

lights, provide a wide beam in a dispersed

paern so that the light is visible from a wider

angle. For best results, use both types of lights.

WARNING: A bicycle without

correct lights and reflectors might be

dicult for other people to see, and

you might not be able to see. If you

cannot see, or other people cannot see

you, you could have an accident. Make

sure your lights operate correctly

and that batteries are charged.

Trek Lync Owner’s Manual Supplement

Parts of the System

Explanaon of the system

The Lync lighng system uses a rechargeable

Lithium Ion baery to power a headlight and

two taillights. Each light uses a high-output

LED (Light-Eming Diode) with a specially-

engineered reector. This combinaon creates

a light that is visible from a wide angle.

Tools needed

The Lync includes a micro-USB cable for

recharging the baery. You will need a

2mm hex wrench to adjust the angle of the

headlight.

Baery pack

The Lync system uses a Lithium Ion baery,

which is housed inside a small case, or baery

pack. The baery pack can easily be removed

from the bike for recharging.

Parts of the system

Specicaons:

• Lithium Ion baery

• 3100mAh 3.7V

Noce: Avoid mishandling of the baery pack.

These acons or others can cause damage to

or permanently disable the baery pack:

• Recharging the baery when hot, such as when

sing in direct sunlight

• Cleaning the baery pack with a high-pressure

washer

• Dropping or impacng the baery pack

• Immersing the baery pack in water

• Opening or puncturing the baery pack

• Short-circuing the terminals

With a full charge, the baery should power

the Lync light system for about two hours

forty minutes at full power, or ve hours at

low power. This me will vary according to

baery condion, temperature, and other

environmental factors. When the baery

charge is at 10% or lower, a red indicator light

will ash on the upper poron of the baery

pack. The indicator light stops ashing if the

baery pack is removed from the bike.

Traveling with Lithium Ion baeries

With a Lithium Ion baery, certain restricons

on travel apply. If the terminals are shorted on

a Lithium Ion baery, it can cause the baery

to overheat and possibly cause a re. For

this reason, airlines do not allow Lithium Ion

baeries in checked baggage; you must put

Lithium Ion baeries in your carry-on. Always

check with the carrier before traveling with

Lithium Ion baeries.

Extending the baery life

The Lync system baery is a long-life system.

The expected life of the baery is 300 to 400

charges. To extend the baery life, store it in

a mostly-charged (not fully-charged) condion

at room temperature, and avoid extreme

temperatures when recharging.

Storing the baery pack

When not using the baery pack for long

periods of me such as a week or more, store

it at room temperature in a dry place. Avoid

moisture, or extreme hot or cold.

Store the baery pack in the charged condion.

Baery life will decrease if the baery pack is

stored in a fully-discharged condion.

To remove the baery pack

1. Push and hold the latch (Figure 2) while you slide

the baery pack along the down tube (Figure 3)

about 5mm (1/8“).

2. Li the baery pack away from the dock (Figure 4).

To install the baery pack

1. Make sure the baery pack and dock are clean.

If required, wipe the contacts with a damp cloth,

ngerp, or pencil eraser.

2. Place the baery pack at on the dock in posion

for installaon (Figure 3) so that the hooks (Figure

3. Slide the baery pack along the dock unl the

latch locks the baery pack into place.

You should hear a ‘click’ when the latch engages.

The red indicator light on the baery will

illuminate for about three seconds, and the front

and taillights will ash momentarily.

Recycling

The baery will eventually lose

strength. When the charge no

longer lasts as long as it should,

purchase a new baery pack

from your dealer. When you do,

please recycle the old baery

pack. In the U.S. go to

hp://www.call2recycle.org/

Outside the U.S., ask your dealer

for the locaon of a recycling center.

Dock

The dock is located on the down tube of the bike

frame, near the crankset (Figure 5). When the

baery pack is removed from the bike, use the

dock cover to protect the electrical contacts of

the dock (Figure 6).

If the baery pack (Figure 2) is on your bike, the

dock is underneath the baery pack.

Wires

The wires run inside the frame. On any

electrical system, the integrity of the wires

and connecons are crical for the system to

funcon. The connecons on the Lync system

are a high-quality, posive-engagement type

and resistant to water.

Avoid contaminang the wires or connecons

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 malfuncon.

FIGURE 8

Control panel with buons

for headlight and taillights

Control panel

The control panel is located under the top tube

of the frame, near the head tube (Figure 8). It

has two buons; the front buon is for the

headlight, the rear buon is for the taillights.

They control the light funcons.

Lights

The headlight of the Lync system is in the

head tube (Figure 7). It can be switched to O,

High, or Low. There are two taillights: one in

each of the rear dropouts. The taillights can

be switched to On, Flash, or O.

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

baery 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 adjusng screw

is located just above the light (Figure 7) and

accessible through the cover. Do not turn

the screw past the stop; overghtening 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.

Parts of the System

To recharge the baery

1. Remove the baery from the dock.

2. Plug your computer to a power source.

3. Connect the baery pack to the computer with

the supplied micro-USB cord. To access the port

on the baery pack, li the cover (Figure 11).

Alternately, connect the baery pack to a wall

charger with the micro-USB cord.

Note: There is no data exchanged with the

computer.

Time required

With a completely empty baery, it takes

about 6 hours to achieve a full charge.

When using a USB hub, charging may be slow.

In that case, connect the USB cable directly

to a computer’s USB port or use a USB wall

charger.

Indicator lights while charging

While charging, the baery pack indicator

light is red. When the baery pack has a full

charge, the indicator light changes to green.

Riding with the Lync

This secon explains the very easy operaon

of the Lync lighng system.

Switching the lights o, on, and

ashing

The control panel has two buons; the front

buon is for the headlight, the rear buon

is for the taillights. They control the light

funcons. To switch to On or change the

mode, push a buon. To switch to O, hold

the buon:

• Front: High, Low, and O

• Rear: On, Flash, and O

If you choose to use the control panel while

riding, be careful to maintain control of the

bike while your hand is o the handlebar.

Baery pack indicator light

When the baery charge is at 10% or lower,

the indicator light on the baery pack (Figure

9) will show red. In addion, the headlight

will start a slow-blink paern and the taillights

will ash.

Recharging the baery

This secon explains about recharging the

baery on the Lync system.

For best results, recharge the baery at

room temperature. Recharging the baery

at extremes of temperature can result in less

than a full charge. Also avoid moisture when

recharging. It is best to do so inside your

home or oce.
