Important Safety and Product

Information

Connecting the Device to

Your Computer or Charger

NOTICE

To prevent corrosion or short circuit,

thoroughly dry the USB port and the

surrounding area before charging or

connecting to a computer.

Device Care

• Use air to blow out dust that may

accumulate in the USB port

• Do not direct a spray of water at the

device

• Intermittently check that the bolts on

the bracket are tightened and not

loosening while riding. Suggested

torque for bolts is 1N.m

• After very muddy or rainy rides,

remove the back cover and clean the

Karoo and cover under cool running

water. Do not use strong detergents or

solvents. Ensure that the buttons and

ports are free of debris.

• Only use a coin that ﬁts the slot well to

gently remove the bottom cover. Do

not use a tool, as this may damage

the device.

• Do not store the device where

prolonged exposure to extreme

temperatures can occur, because it

can cause permanent damage.

• Never use a hard or sharp object to

operate the touchscreen, or damage

may result.

• Avoid chemical cleaners, solvents, and

insect repellents that can damage

plastic components and ﬁnishes.

About the Battery

A lithium-ion battery can be used in

this device. If these guidelines are not

followed, batteries may experience a

shortened life span or may present a risk

of damage to the device, ﬁre, chemical

burn, electrolyte leak, and/or injury.

• Do not disassemble, modify,

remanufacture, puncture, or damage

the device or batteries.

• Do not remove or attempt to remove

the non-user-replaceable battery.

• Do not expose the device or batteries

to ﬁre, explosion, or other hazard.

• Do not use a sharp object to remove

the removable batteries.

• Do not leave the device exposed to a

heat source or in a high-temperature

location, such as in the sun in an

unattended vehicle. To prevent the

possibility of damage, remove the

device from the vehicle or store it out

of direct sunlight, such as in the glove

box.

• If an event causes the device to ignite

only use a Class - D ﬁre extinguisher.

• Do not operate the device outside of

the temperature ranges 10°C to 50°C.

• When storing the device for an

extended time period, store within the

temperature ranges of 5°C to 25°C

• Do not use a power adapter that

exceeds an output of 3A

• Contact your local waste disposal

department to dispose of the

device/batteries in accordance with

applicable local laws and regulations.

• KEEP BATTERIES AWAY FROM CHILDREN.

• NEVER PUT BATTERIES IN MOUTH.

Swallowing can lead to chemical

burns, perforation of soft tissue, and

death. Severe burns can occur within

2 hours of ingestion. Seek medical

attention immediately.

WARNING

Failure to heed the following warnings

could result in an accident or collision

resulting in death or serious injury.

• Always consult your physician before

beginning or modifying any exercise

program.

• If you have a pacemaker or other

internal electronic device, consult your

physician before using a heart rate

monitor.

• The Hammerhead device, accessories,

heart rate monitor, and related

data are intended to be used only

for recreational purposes and not

for medical purposes, and are not

intended to diagnose, monitor,

treat, cure, or prevent any disease or

condition.

• The heart rate readings are for

reference only, and no responsibility is

accepted for the consequences of any

erroneous readings.

Bicycle Warnings

• Always use your best judgement, and

operate the bicycle in a safe manner.

• Make sure your bicycle and hardware

are properly maintained and that all

parts are correctly installed.

Off-Road Navigation Warnings

If your Hammerhead device is able

to suggest off-road routes for various

outdoor activities, such as biking, follow

these guidelines to ensure safe off-road

navigation.

• Always use your best judgment and

exercise common sense when making

off-road navigational decisions. The

Hammerhead device is designed to

provide route suggestions only. It is

not a replacement for attentiveness

and proper preparation for outdoor

activities. Do not follow the route

suggestions if they suggest an illegal

course or would put you in an unsafe

situation.

• Always carefully compare information

displayed on the device to all available

navigation sources, including trail

signs, trail conditions, weather

conditions, local government law and

other factors that may affect safety

while navigating. For safety, always

resolve any discrepancies before

continuing navigation, and defer to

posted signs and conditions.

• Always be mindful of the effects of the

environment and the inherent risks of

the activity before embarking on off-

road activities, especially the impact

that weather and weather-related

trail conditions can have on the safety

of your activity. Ensure that you have

the proper gear and supplies for

your activity before navigating along

unfamiliar paths and trails.

GPS Notice

The navigation device may experience

degraded performance if you use it

in proximity to any device that uses

a terrestrial broadband network

operating close to the frequencies

used by any Global Navigation Satellite

System (GNSS), such as the Global

Positioning Service (GPS). Use of such

devices may impair reception of GNSS

signals.

The navigation device may experience

degraded performance when used

under heavy tree coverage, within

tunnels, or within large sheer-walled

canyons or valleys. This is inherent to the

antenna being shielded from available

satellites; always use caution when

planning routes through this type of

terrain and ensure that you have a clear

understanding of what navigational

decisions may be required should you

lose navigational guidance.

Radio Frequency Radiation Exposure

This device is a mobile transmitter

and receiver that uses an internal

antenna to send and receive low levels

of radio frequency (RF) energy for data

communications. The device emits

RF energy below the published limits

when operating in its maximum output

power mode and when used with

Hammerhead authorized accessories.

The device should not be used in other

conﬁgurations. This device must not be

co-located or operated in conjunction

with any other transmitter or antenna.

Regulatory Labeling

This device uses e-labeling to display

regulatory information. To access

regulatory information on the device

follow these steps:

• Tap “Settings”

• Tap “About”

• Tap “Regulatory Information”

All regulatory and certiﬁcation

information for the device will be

displayed.
