DUO 1025 Dual-Use Heart Rate Monitor  
INTRODUCTION  
Congratulations on your purchase of a Sportline Personal Fitness Monitor. Please keep in mind; your  
watch is a sensitive technical instrument. With proper care and maintenance, it will last for many  
years. However, improper care and handling can cause the various sensors to be damaged and to stop  
functioning.  
HOW TO USE THIS MANUAL  
Sportline Personal Fitness Monitors have many unique features and functions. Please read all sections  
of this manual carefully and become fully familiar with the operation of the watch before using it in  
the field.  
Proper setup and operation will greatly enhance the watches usefulness and your enjoyment.  
The manual is divided into sections outlining each of the major functions of the watch. A drawing of  
the watch screen that represents the starting point or other important screens for each operational  
process are shown adjacent to the instructions for the process; important keys are shown indicating  
PRESS & HOLD and PRESS.  
The steps for the programming or operation are adjacent to the screen illustration. Key points and  
important information are shown in highlighted blocks.  
ACTIVATING THE WATCH FROM POWER DOWN MODE  
PLEASE NOTE: Your watch was originally shipped in Power Down Mode to conserve battery life.  
To deactivate Power Down mode: PRESS & HOLD ANY KEY for 3 seconds (see page 10 for more  
information on Power Down mode).

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.

DO NOT expose the unit to extreme heat, shocks, magnetic fields, electrical noise, strong vibration  
or long-term exposure to direct sunlight.  
DO NOT drop or step on the watch.  
TO CLEAN THE UNIT: wipe with a lightly moistened cloth. Apply mild soap to the area if there are  
stubborn stains or marks. Do not expose the unit to strong chemicals such as gasoline, cleaning

ACQUIRING HEART RATE  
ACQUIRING HEART RATE: FINGER TOUCH  
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 of the watch) with your index finger.  
NOTE: If Heart Rate Sensors are 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 SENSOR. Heart Rate will continue to display for a period  
of approximately 5 seconds.  
OR  
 
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.  
NOTE: If Chest strap heart rate is captured, finger touch heart rate will be disabled.

DUO 1025 Dual-Use Heart Rate Monitor  
SETTING THE WATCH FUNCTIONS  
HEART RATE TARGET ZONES  
The Sportline Duo 1025 allows you to select from 3 preset Heart Rate Target Zones (ACTIVE, FAT  
BURN and ENDURANCE) 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 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.  
Active Zone: 50% - 60% 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: 60% - 75% of maximum heart rate.  
Exercising in this zone strengthens the cardiovascular system and nearly all the calories burned are  
from fats.  
Endurance 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.

REPLACING THE WATCH BATTERY  
The Sportline Duo 1025 uses a single CR2032 lithium battery.  
Battery replacement will be required from time to time, and should occur when:  
1. The display fades in part or completely  
2. The heart rate function will not activate  
3. Backlight System does not operate  
To replace the battery of your Sportline Duo 1025, we recommend you take it to a watch repair  
service center or certified jeweler. This will ensure that the water resistance will be retained after  
battery replacement.  
CUSTOMER SUPPORT  
If you have questions, comments or need assistance with your Sportline Duo 1025 Heart Rate Watch,  
you may contact Customer Support by calling 1-800-338-6337.  
 
25  
REPLACING THE CHEST TRANSMITTER BATTERY  
The Sportline Duo 1025 features a wireless heart rate transmitter, powered by a CR2032 3v Lithium  
battery. Under normal conditions you can expect to get approximately 300-400 hours of heart rate  
transmitter use with a fresh battery. To replace the battery:  
1. Using a coin, turn the battery door counter clockwise until the door comes free of the watch.  
2. Take care not to damage the O-ring seal for the battery compartment and carefully remove the old  
battery.  
3. Place a new battery in the battery compartment with the positive (+) side toward the battery door.  
4. Place the battery door over the opening and tighten it down by using a coin and turning in a  
clockwise direction.  
5. If the O-ring has been damaged, replace it before reinstalling the battery door. Most jewelers and  
watch shops should have replacement O-ring seals.  
NOTE: Extreme care should be taken when replacing  
the battery to ensure the unit remains fully water  
resistant. Failure to properly replace the battery and  
correctly seal the unit may cause the unit to become  
damaged and may void the warranty.

TROUBLE SHOOTING  
Apply conductive gel thoroughly to chest area (for Chest-Strap measurement) or finger (for  
Finger-Touch measurement). Tap water may help if conductive gel is not available.  
Make sure the chest strap is firmly over the chest and the Watch is securely on wrist.  
Decrease finger pressure on the Sensor Pads.  
Rub off excessive dead skin with a towel  
Wipe chest / wrist and the back of Chest Strap/ watch with a tissue or soft towel.  
Apply conductive gel to chest area or wrist.  
Replace the battery in watch/transmitter and try again.  
Leave the area where RF source potentially exist.
