INTRODUCTION
Thank you for selecting the Oregon ScientificTM Heart Rate
Monitor (SE128). The SE128 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 SE128 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 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 exercise 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.
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.
SE128 EN R5.indd 2 2007.7.6 10:27:22 AM

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 effi cient
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 specifi c 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 fi lm of sweat to improve contact with
the skin.
THE RECEIVER
The receiver comes in the format of a wristwatch.

EFFECTIVE RANGE
The transmitter and receiver will start transmitting and
receiving signals after the batteries are in place. When
the battery is full, both units can be worn or mounted up
to 76 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.

ADDITIONAL INFORMATION
BATTERY
The SE128 uses a CR2032 lithium battery for the
transmitter and a CR2032 for the receiver. Both are
included with the unit. When the receiver battery is
running low, the low battery indicator will light up
on the watch display.
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
