WARNINGS & CAUTIONS  
WARNING: Before starting any exercise program or performing any vigorous physical activity, we  
strongly suggest you visit your doctor for a complete physical and to discuss your plans.  
CAUTION: Your watch is designed to be water resistant to a static pressure of 5 ATM and can be worn  
while showering and light swimming. However, we recommend that extensive use of the unit in the  
water be avoided whenever possible. Care should be taken not to press any keys while the unit is  
submerged as this can force moisture past the key seals and damage the unit.  
CAUTION: Avoid exposing your watch to extreme conditions for a prolonged period of time.  
CAUTION: Avoid rough usage or severe impacts to your watch.  
DO NOT use hand cream as it will insulate the signal between the skin and sensor contacts.  
DO NOT use the fingertips where the skin is dry and thick. For those with extremely dry skin, moisten  
fingers and wrist with tap water or a conductive gel.  
CLEAN the Back Cover occasionally by using a damp cloth. Then wipe dry to remove any residual  
grease.  
CLEAN your skin and fingers with soap and water for a better signal transmission.  
AVOID doing awkward motions during measurement. It may create inaccurate heart rate readings.

Heart rate may be acquired from any operating mode (not in any Setting Sequence).  
1. With the watch attached to your wrist, TOUCH & HOLD the HEART RATE SENSOR (anywhere on the  
metal top plate) with one finger.  
NOTE: If Heart Rate Sensor is accidentally touched, the watch will automatically attempt to acquire heart rate. If no  
heart rate is detected, watch will resume operating mode in approximately 10 seconds. This will not interfere with  
any timing functions in progress.  
NOTE: You may exit Heart Rate mode at any time by Pressing the Mode, Start/Stop or Reset key.  
2. Continue TOUCHING & HOLDING until heart rate displays.  
3. Once Heart Rate is acquired, RELEASE THE SENSORS. Heart Rate will continue to display for a  
period of approximately 10 seconds.  
 
7
ACQUIRING HEART RATE  
ACQUIRING HEART RATE WEARING THE CHEST STRAP TRANSMITTER  
The Chest Strap Transmitter provides constant heart rate information throughout the duration of your  
workout. To ensure a proper heart rate display, the chest transmitter must be properly adjusted. Snap  
the plastic tabs at the end of the elastic belt into the holes at the end of the transmitter and adjust the  
strap so that the transmitter fits tightly below the pectoral muscles, as shown in the drawing.  
NOTE: Users with significant chest hair may have a problem obtaining contact between the transmitter electrodes and  
their skin, resulting in poor performance. It may be necessary for these individuals to shave the area of their chest  
beneath the transmitter.  
NOTE: In dry and cold climates it may take a few minutes for a layer of perspiration to form between the chest strap  
and the skin. Moistening the electrodes with saliva or ECG conductive gel can speed up this process.

Duo 1010 Dual-Use Heart Rate Monitor  
SETTING THE WATCH FUNCTIONS  
HEART RATE TARGET ZONES  
The Sportline Duo 1010 Heart Rate Watch allows you to select from 3 preset Heart Rate Target Zones  
(AEROBIC, FAT BURN and HEALTH) and 1 user-defined Target Zone. The watch tracks time IN, ABOVE  
and BELOW Target Zone during exercise.  
SELECTING YOUR TARGET HEART RATE ZONE  
Losing weight and managing to keep it off is a lot easier when you exercise in your target heart rate  
zone. To determine your target heart rate zone, first subtract your age from 220. That’s an estimate of  
your maximum heart rate. To get the most out of any exercise program, you should target 50% to 85%  
of your maximum heart rate depending on your fitness level and objectives.  
Health Zone: 50% - 65% of maximum heart rate.  
This zone is ideal for fitness beginners on a low to moderate intensity program. Exercising in this zone  
reduces blood pressure and cholesterol.  
Fat Burning Zone: 65% - 75% of maximum heart rate.  
Exercising in this zone strengthens the cardiovascular system and nearly all the calories burned are  
from fats.  
Aerobic Zone: 75% - 85% of maximum heart rate.  
Reaching this zone requires more intense aerobic activity and is perfect for fitness enthusiasts  
working to burn maximum calories from fat and carbohydrates. Cardiovascular strengthening,  
increased metabolism and elevated caloric burn are the primary benefits.

CAUSE: DEAD SKIN ON WRIST, FINGER OR CHEST.  
SOLUTION: Rub off excessive dead skin with a towel  
CAUSE: A THIN LAYER OF BODY GREASE INSULATES THE ECG SIGNAL PREVENTING THE CHEST STRAP OR  
WATCH FROM DETECTING ECG HEART RATE  
SOLUTION: Wipe chest / wrist and the back of Chest Strap/ watch with a tissue or soft towel.  
CAUSE: HAIRY SKIN  
SOLUTION: Apply conductive gel to chest area or wrist.  
CAUSE: LOW BATTERY  
SOLUTION: Replace the battery in watch/transmitter and try again.  
CAUSE: ELECTRICAL FIELD INTERFERENCE FROM RF DEVICES (CHEST-STRAP MEASUREMENT) SUCH AS  
OVERHEAD POWER LINES, ETC.  
SOLUTION: Leave the area where RF source potentially exist.
