WARNING: 

If you choose to use the eTrex in a vehicle,

it is the sole responsibility of the owner/operator of the eTrex
to secure the GPS unit so that it will not cause damage or
personal injury in the event of an accident. Do not mount
the eTrex over airbag panels or in a place where the driver
or passengers are likely to have an impact with it in an acci-
dent or collision.

WARNING: 

If you choose to use the eTrex in a

vehicle, it is the sole responsibility of the operator of the
vehicle to operate the vehicle in a safe manner, maintain
full surveillance of all driving conditions at all times, and
never become distracted by the eTrex to the exclusion of
safe operating practices. It is unsafe to operate the eTrex
while you are driving. Failure by the operator of a vehicle
equipped with an eTrex to pay full attention to operating
the vehicle and road conditions while the vehicle is in
motion could result in an accident or collision with
property damage and personal injury.

CAUTION:

 IT IS THE USER’S RESPONSIBILITY TO

USE THIS PRODUCT PRUDENTLY. THIS PRODUCT IS
INTENDED TO BE USED ONLY AS A TRAVEL  AID
AND MUST NOT BE USED FOR ANY PURPOSE
REQUIRING PRECISE MEASUREMENT OF DIREC-
TION, DISTANCE, LOCATION, OR TOPOGRAPHY.

CAUTION:

 The Global Positioning System (GPS) is

operated by the government of the United States, which is
solely responsible for its accuracy and maintenance. The
system is subject to changes which could affect the
accuracy and performance of all GPS equipment.
Although the eTrex is a precision electronic NAVigation
AID (NAVAID), any NAVAID can be misused or misinter-
preted and, therefore, become unsafe.

Warnings and

Cautions
