Heart Rate Alerts
Note: Heart rate alerts are a feature
of the Forerunner 305 only.
The heart rate alert notifies you if
your heart rate exceeds or drops
below a specific number of beats
per minute (bpm).
Heart rate alerts can also notify
you if your heart rate exceeds
or drops below a certain heart
rate zone—a range of beats

Training
Using Cadence Alerts
Note: Cadence alerts are a feature
of the Forerunner 305 only and can
only be set in Biking mode.
If you own an optional Garmin
cadence sensor (GSC™ 10), you
can use cadence alerts. The
cadence alert notifies you if your
cadence exceeds or drops below
a specific number of revolutions
of the crank arm per minute
(rpm).
Setting a cadence alert is similar
to setting a heart rate alert. The
maximum cadence value allowed
is 255. Be sure to change to
Biking mode when setting a
cadence alert.
Training with Cadence
Cadence is your rate of pedaling
or “spinning” measured by the
number of revolutions of the
crank arm per minute (rpm).
There are two sensors on the
GSC 10: one for cadence and
one for speed. Cadence data
from the GSC 10 is always
recorded. The speed data from
the GSC 10 is only recorded and
used for distance calculation
when the GPS signal is weak or
the GPS is turned off.
For information about speed
zones, see page 50.

range of heartbeats per minute
(bpm). The five commonly
accepted heart rate zones are
numbered from 1–5 according to
increasing intensity. Generally,
heart rate zones are calculated
based on percentages of your
maximum heart rate. See the
next page to learn some of the
Forerunner® 205/305 Owner’s Manual
effects of exercise as your heart
rate reaches each of these
zones.
How do heart rate zones
affect your fitness goals?
Knowing your heart rate
zones can help you measure
and improve your fitness by
understanding and applying these
principles:
• Your heart rate is a good
measure of exercise
intensity.
• Training in certain heart
rate zones can help you
improve cardiovascular
capacity and strength.
• Knowing your heart rate
zones can prevent you
from overtraining and
decrease your risk of injury.
57
Appendix
How can I determine my
heart rate zones?
See the next page to learn about
the benefits of training in each
heart rate zone.
If you know your maximum heart
rate, you can enter it and allow
the Forerunner to calculate your
Zone
% of Max.

About Pairing
Pairing is the process of matching
sensors, like your heart rate
monitor, with your Forerunner
305. This process occurs
automatically when you turn on
the Forerunner and only takes a
few seconds when the sensors
are on and functioning correctly.
Once paired, your Forerunner
will only receive data from your
sensor. Upon power up, the
Forerunner will automatically
scan for the sensors you
have enabled (see “Adding
Accessories,” page 46). Each
sensor has a unique ID. The
Forerunner learns and saves this
Forerunner® 205/305 Owner’s Manual
unique ID while pairing the first
time. The next time you turn on
the Forerunner, it will only pair
with the unique sensor ID. If the
Forerunner does not find the
sensor, you should restart the
scan to find your sensor ID.
Interference
Strong electromagnetic fields
can interfere with your heart rate
monitor and cause your heart
rate to appear unusually high,
freeze, or disappear. Common
sources of interference include
high voltage power lines, electric
motors, computers, televisions,
and mobile phones. After you
move away from the source of
interference, your heart rate
reading should return to normal.
59
Appendix
Heart Rate Monitor
Troubleshooting
• Replace the battery.
• Clean the sensors. Dirt and
sweat build-up on the sensors
can weaken signals.
• Reapply moisture. Use
electrode gel, water, or saliva.
• Make sure the heart rate
monitor is snug against your
body. If you have trouble with
erratic readings, position the
transmitter on your back.
• Wear a cotton shirt, or wet
your shirt. Synthetic fabrics
that rub or flap against the
heart rate monitor can create
static electricity that interferes
with heart rate signals.
60
Forerunner® 205/305 Owner’s Manual
If you have trouble pairing with
the heart rate monitor, or if your
heart rate readings are erratic, try
the following suggestions.
• Position the Forerunner within
3 meters of the sensor while
pairing.
• Stay far away from any other
sensors while pairing.
• Move away from sources of
interference (see the previous
page).
• Restart scan if your
Forerunner appears to be
paired with another sensor
(see page 46).
• Make sure scanning for the
heart rate monitor is enabled
(see page 46).
