Data Recording
Data recording controls how the
Forerunner records detailed data
for your runs or other activities.
By default, the Forerunner uses
Smart Recording to record your
movements and create detailed
history. Smart Recording picks
up key points where you change
direction, speed, or heart rate.
You can also record data every
second. Doing so creates the
most accurate record possible of
your activity. However, with this
setting, the Forerunner can only
record up to 3.5 hours of detailed
data.
NOTE: When the history is full,
older history data is overwritten
automatically. Be sure to transfer
history to Garmin Training Center
often.
To change data recording:
1. From the Main Menu, select
Settings > General > Data
Recording.
2. In the Record Data Points
eld, select Every Second or
Smart Recording.
Adding Accessories
The Forerunner 305 has two
possible accessories: a heart rate
monitor and an optional Garmin
cadence sensor. You can enable
these accessories from this menu
or restart scanning if you are
having trouble receiving data.
To scan for accessories:
1. From the Main Menu, select
Settings > General >
Accessories.
