INTRODUCTION
Thank you for selecting the Oregon ScientificTM Heart Rate
Monitor (SE122). The SE122 is a very useful sports &
fitness product that can help you achieve and maintain your
optimum exercise zone by monitoring your heart rate while
exercising. The SE122 bundles a heart rate transmitter and
receiver watch complete with real-time clock, stopwatch,
and backlight functions.
KNOW YOUR DATA
To help achieve the maximum health benefits from your
workout program, it is important to know your:
• Maximum heart rate (MHR) training zone
• Upper heart rate limit
• Lower heart rate limit
MHR is expressed in beats per minute. You can get your
MHR from a MHR test, or you can estimate it using the
following formula:
220 - age = MHR
There are several training zones that are relevant to a
fitness program. The most popular zone range is from
50% to 80% of your maximum heart rate. This is where
you achieve cardiovascular benefits, burn fat, and become
fitter. When programming your watch, the lower % of the
zone you choose becomes your lower heart rate limit and
the higher % becomes the upper heart rate limit.
50%
60%
70%
80%
90%
100%
Moderate Activity
Weight Management
Aerobic Zone
Anaerobic Threshold Zone
Red Line Zone ( maximum capacity )
The upper and lower heart rate limits are calculated by
multiplying your MHR by the percentages of the selected
training zone.
For example:
A 40-year-old user training for basic health maintenance:
• His Upper Heart Rate Limit [220 - 40(age)] x 78%
• His Lower Heart Rate Limit [220 - 40(age)] x 65%
TRAINING ZONES
Always warm up before exercising and select the training
zone that best suits your physique. Exercise regularly, 20
to 30 minutes per session, three to four times a week for a
healthier cardiovascular system.

EN
3
There are three training zones, as described below:
TRAINING
ZONE MHR% DESCRIPTION
Health
Maintenance 65-78%
This is the lowest
training intensity level.
It is good for beginners
and those who
want to strengthen
their cardiovascular
systems.
Aerobic
Exercise 65-85%
Increases strength
and endurance. It
works within the
body’s oxygen intake
capability, burns more
calories and can be
maintained for a long
period of time.
Anaerobic
Exercise 78-90%
Generates speed
and power. It works
at or above the
body’s oxygen intake
capability, builds
muscle, and cannot be
maintained for a long
period of time.
WARNING Determining your individual training zone
is a critical step in the process towards an efficient and
safe training program. Please consult your doctor or
health professional to help you determine your maximum
heart rate, upper and lower limits, exercise frequency and
duration appropriate for your age, condition and specific
goals.

THE TRANSMITTER
The transmitter is used to count your heartbeat and transmit
the data to the receiver. To put it on:
1. Wet the conductive pads on the underside of the
transmitter with water or a conductive gel to help
establish a solid contact.
2. Strap the transmitter across the chest. Adjust the strap
until the transmitter sits snugly below the pectoral
muscles for an accurate heart rate signal.
HINTS
• The position of the transmitter affects its performance.
Move the transmitter along the strap for the best
transmission. Avoid areas with dense chest hair.
• In dry, cold climates, it takes the transmitter a while to
function steadily. This is normal, as the conductive pads
need a film of sweat to improve contact with the skin.
NOTE To maintain the best performance of your chest belt,
please handle it with care according to the following:
• Do not wrap the chest belt in a wet towel nor with other
wet materials.
• Do not store the chest belt in a hot (about 50°C) and
humid (about 90%) environment.
• Do not place or wash the chest belt under running
water, instead clean it with a wet cloth.
• Do not place the conductive rubber face down on a
metal table or surface.
• Properly dry the chest belt immediately after use.

cm (30 inches) apart.
If signals become unsteady:
• Shorten the distance between the transmitter and
receiver.
• Re-adjust the position of the transmitter.
• Check the batteries. Replace them when necessary.

If the heart rate readings become erratic or stop, your
transmitter battery may need replacing.
To change the battery:
1. Open the transmitter battery lid with a coin by turning it
counterclockwise.
2. Insert a new CR2032, 3V lithium battery.
3. Replace the battery compartment door.
NOTE Take care not to touch the two contacts otherwise
the battery can discharge. If you are unsure about the
procedure consult your dealer.
ENERGY SAVING FEATURE
