Before Using the Unit
INTRODUCTION
Thank you for purchasing the OMRON HJA-313
activity monitor. This monitor uses OMRON’s
proprietary “Active Engine 2” technology to
measure your physical activities, including
household chores, desk work and walking, and
calculates the number of calories you have burned
in a day. This monitor is an everyday tool that can
help you find a healthy balance between diet and
exercise.
THE OMRON JOG STYLE FEATURES
 Keeping your jogging records
Records of your jogging such as the amount of
time, distance, calories burned during the run,
and pace at which you run can be checked at
any time.
 Measurement accuracy will still be
assured even when kept in a pocket
Even when this activity monitor is kept in a
pocket, it will deliver accurate measurement
results. You can wear it anywhere.
 Weekly diet support function
This activity monitor has a function that
supports your weight reduction program (refer
to “Weekly Diet Support” on page 3).
 Backlight
This activity monitor has a backlight for night

INTRODUCTION
Workout
This term generally refers to exercise or training
conducted to improve health or tness. However,
in this manual, it refers to one jogging or walking
training session that you perform.
Calories Burned
This monitor displays activity calories and
total calories burned separately. The number of
activity calories serves as an exercise guideline.
The total number of calories burned is useful for
controlling your diet.

Weekly Diet Support
yWhen you set how much weight you want to
lose in the next four weeks (weight reduction
target), the activity monitor calculates the
target amount in terms of activity calories
you should burn in a week and supports your
weight reduction goals.
yThe weekly target of activity calories is
displayed as 100%.

INTRODUCTION
yThe value for the usual activity calories
is updated every four weeks according to
your activities. However, the average value
calculated from your personal data is used for
the rst few days.
yThis activity monitor cannot measure the
amount of calories you have taken in. If you
have failed to achieve the weight reduction
target, you may have taken in more calories
than you have burned.
yThe weight reduction target is a guideline. It is
not guaranteed that you will lose that amount
of weight.
yThe week starts on a Sunday.
* If you set your target on any
day other than Sunday, it is not
displayed until the next Sunday
comes.
Example of display:
when the target is set on a
Thursday
NOTE: DLeft 3 indicates that Weekly Diet
Support will start after three days
have elapsed.

INTRODUCTION
 Displayed values
The display shows a guideline for the amount of
activity time per day required to achieve your
weekly target* and a percentage indicating the
level of achievement.
* The activity period is calculated on the assumption
that all of your activities involve walking (4 km/h).
Actually, your daily activities also reduce the activity
period, however, jogging or other vigorous activities
reduce it faster.
Today’s target amount of activity time changes
depending on the activities you performed on
previous days.
 Achievement level indicator
This indicator shows how much of your weekly
target has been achieved.
 Congratulations mark
This mark is displayed when you have achieved
your weekly target. When you have almost
achieved your weekly target, the mark raises one
hand to encourage you.

 Stride length
yThe value blinking on the display is a reference
value calculated according to the height you set.
Adjust your stride length by considering your
walking style and physical size.
yTo calculate your stride length more accurately, walk
or run about 10 steps and then measure the length of
one step (from toe to toe or from heel to heel).
yThe unit automatically differentiates between
walking and running and separately measures the
distances based on the respective stride lengths and
step counts.
For this reason, you need to set your walking stride
length for the WALK stride length, and running
stride length for the JOG stride length.
