1 Introduction

Dear customer,
Thank you for purchasing this high-quality OMRON activity
monitor. The new Jog style will keenly measure your physical
activity and helps to assist with your diet or motivates you to
reach your daily walking target.
The OMRON Jog style HJA-300 uses OMRON’s new Active
Engine technology to measure the intensity and amount of
exercise, ranging from walking to jogging and running.
In addition to measuring the step count and the number of
calories burned during everyday activities, it can also keep a
record of each workout. This makes it useful for planning an
exercise program based on the intensity of your training.

■

Active Engine

This OMRON technology can accurately detect and calculate
any fast or slow signals caused by physical activity.
Active Engine makes it possible to monitor not only the
physical activity of walking, but can also capture the more
intense activity of jogging in real time and calculate the
amount of fat and calories burned.

■

Workout

For most health related activities, “workout” means a training
program to improve your fitness. However, in this instruction
manual it is used to refer to one training period of jogging or
walking.

■

The OMRON Jog style Features

Fat burned/Calories burned

By measuring the intensity of your activity, the unit can
calculate the amount of fat and calories burned.

Workout mode

Workout mode records the time between when a workout
is started and when it is stopped as single record, using
stopwatch like display (refer to Chapter 6.3).
The data includes the distance, time, calories burned and
average speed for each workout.
The unit automatically records the workout data for up to
7 previous sessions.

Workout stopped

If a workout continues for more than 30 minutes, the
message “Good job” scrolls on the display after you finish
Workout mode.

2 Use of the OMRON Jog style

2.1 Cautions

• Do not look at the display while jogging. Always stop where
it is safe to do so before checking the display.

• Contact your doctor or healthcare provider before beginning
a weight reduction or exercise program.

• Always take a rest if you feel tired or experience pain while
exercising. If the pain or discomfort continues, immediately
stop your exercise and consult a doctor.

• Keep the unit out of the reach of young children.

• If young children swallow the battery, battery cover or screw,
immediately consult a doctor.

• Do not swing the unit by the strap. Swinging the unit while
holding the strap may cause an injury.

• Do not put the unit in the back pocket of your shorts or
trousers. It could be damaged if you sit down while the unit
is still in your pocket.

• If battery fluid should get in your eyes, immediately rinse
with plenty of clean water. Consult a doctor immediately.

• If battery fluid should get on your skin or clothing,
immediately rinse with plenty of clean water.

• Do not insert the battery with the polarities in the wrong
direction.

• Always use the type of battery indicated.

• Replace a worn battery with a new one immediately.

• Remove the battery from this unit when you are not going to
use it for a long period of time (approximately 3 months or
more).

9 Battery life and replacement

If the symbol blinks or appears on the display, replace the
battery with a new (CR2032) battery.

Notes:

• Do not replace the battery around midnight (0:00). The
measurement results of the day when the battery was removed will
be added to the measurement results for the day the battery was
inserted.
(It is assumed that the battery will be removed and replaced with a
new one on the same day.)

• The measurement results for calories and fat burned, and the
number of steps are automatically stored in memory on the hour
(e.g. at 0:00, 1:00, 2:00, ... 21:00, 22:00, 23:00). The measurement
results from the hour until the time the battery is replaced will be
deleted for that day.

• When the battery is removed, the time will be reset to “0:00”. Set
the time after inserting the new battery (refer to Chapter 5
“Settings”).
(The measurement results stored in memory and the weight,
height, and stride length settings are not deleted.)

• The attached battery is for trial use. This battery may run out in 4.5
months.

Blinking Battery power is low.

Appears

continuously

Battery power exhausted.
The unit stops counting steps.

Battery life

The battery life will vary depending on how frequently you
workout and on how long the unit is worn.
The following examples offer a guide to expected battery
life.

• Worn during everyday life

- Approx. 4.5 months (4 hours of activity each day)
Everyday life is defined as wearing the unit for 15 hours a day,
of which 4 hours are counted as walking steps.

• Worn only during workouts

- Approx. 6 months
This assumes that the unit is only worn when jogging or
walking for 2 hours (approx. 10,000 steps) a day.

Note:

In both cases, the battery life may be shorter if the amount
of walking or activity increases.
