If ‘GARMIN  DGPS’ or ‘RTCM/NMEA’ format is selected,

additional fields are provided to control a GARMIN
differential beacon receiver (e.g. GBR 21) directly from your
eTrex. You can enter the beacon frequency and bit rate when
you select ‘User’ from the Beacon pop-up list to manually
tune the receiver (you can also ‘scan’ if you don’t know what
the nearby station is, but the unit could continue scanning
if reception is temporarily lost).

1. Press the PAGE button and switch to the ‘MENU’

Page. Use the UP and DOWN button and highlight
the ‘SETUP’ field. Press ENTER. The ‘SETUP’ Page
appears.

2. Press the UP or DOWN button and select the

‘INTERFACE’ field. Press ENTER. The ‘INTERFACE’
Page appears.

3. Press ENTER on the ‘I/O FORMAT’ field. Press the

UP or DOWN button to select the desired format.
Press ENTER. Press PAGE to return to the page of
your choice.

The System Page shows you the current software

version and allows you to choose from three modes of
operation:

• Normal

• Battery Save

• Demonstration (DEMO)

The GPS receiver is turned on all the time when it’s in

‘NORMAL’  mode. The normal mode is more sensitive to
sudden turns or change of speed/acceleration.
