After installing batteries in the Foretrex 101, it is ready for use.  

To turn on the Foretrex 101: 
1.  Press and hold the 

button until the Satellite Page is 

displayed.  

2.  Allow the Foretrex time to track satellites the first time you use 

it.  Leave the Foretrex outside with a clear view of the sky for 
15–30 minutes.  After the first use, it should take less than one 
(1) minute to acquire satellites.  

3.  When the Foretrex acquires enough satellite signals to 

determine your location, “3D GPS FIX” or “2D GPS FIX” is 
displayed, and the satellite dish icon in the upper left corner of 
the screen stops flashing.  Also, the Signal bar fills up to show 
the strength of the satellite signal.  

Foretrex 101 Icons
Three icons in the upper left-hand corner provide at-a-

glance-status of the Foretrex: battery, stopwatch (timer), and 
satellite dish icon.  

Battery icon: The battery icon indicates how much 

power the batteries have.  A full battery icon indicates new  
batteries are installed in the Foretrex 101.  

Timer icon: When the timer feature of the Foretrex is 

being used, the stopwatch (timer) icon displays just below 
the battery icon.  

Satellite Dish icon: When the Foretrex has acquired 

enough satellites to establish your GPS location fix, this icon 
displays solid (not flashing) just below the timer icon.  The Satellite 
Dish icon flashes while it is acquiring satellites and determining 
your location.

The Foretrex 101 operates on two AAA alkaline batteries (not 

included), which are placed in the back of the unit.  Rechargeable 
alkaline, NiMH, NiCad, or lithium batteries may be used.  See the 
section titled “Set System Page” in the Owner’s Manual for instruc-
tions on selecting battery type.

Stored data is not lost when you change the batteries.  However, 

if batteries are completely discharged and are not changed within a 
couple of days, it may take longer for the unit to get a GPS signal fix.

To install the batteries:
1.  Remove the battery cover by inserting a coin in the bottom 

slot.  Twist the coin to lift the cover up and pull away.

2.  Compare the battery polarity with the diagram in the battery 

compartment and install the batteries accordingly.
