READ ME FIRST
For accurate readings and best performance, please read the following
suggestions:
★This product is intended only for the purpose of displaying heart rate
during physical activity and cannot predict the Intensity level that is safe
for you.
It is not a medical device, nor is it intended for medical diagnostic
purposes. Before you begin any exercise program, consult your
physician or doctor.
★Skin types and heart rate signals differ in people. You may need to
take some time to be familiar with the transmitter strap to achieve stable
signals.
Please be patient, especially during the cold, dry winter months.
★Dehydration and alcohol consumption can affect the detection and
accuracy of the heart rate display.
For accurate readings it is advised to wait until your body condition
stabilizes before using the transmitter.
★Body hair can affect the detection and transmission of heart rate
signals. If necessary, trim or shave chest hair where the transmitter
sensing electrodes will contact your skin.
IMPORTANT:
1. Make the metal shell a little stick up, not flat.
2. Make sure to close the battery cover very tightly to prevent sweat and
moisture from spoiling the battery composition.
WEARING THE HEARTRATE CHESTBELT
This heart rate chest belt has a soft textile strap with adjustable buckle design.
Please adjust to proper length to get the effective heart rate detection.
★Before wearing the chest belt, you may check the transmission by pressing
the electrode area with your fingers.
Notice:
1. Use water, ECG gel or other conductive liquids to moisten the conductive rubber skin contact.
2. Do not use vasoline or oils which may insulate the transmitter and make it unable to detect the heart rate signals.
3.
To save power
please make
sure to take off the transmitter when not in use.
TURN ON HEART RATE TRANSMITTER
Bluetooth smart:
The BLE smart Heart Rate Transmitter is compatible with iPhone 4S/5/6,
iPod Touch (5th generation), iPad (3rd and 4th generation) and Android
4.3 or higher. It is also compatible with some sport watches with BLE
smart support such as Polar loop, etc…
Please follow the following steps to connect to a smartphone.
Step 1. Go to Device Settings->General->Bluetooth.
Step 2. Turn On Bluetooth. The Bluetooth©smart device will pair directly
with an application.
Step 3. Pick a compatible fitness application from the “app store” and
download it to the phone. Select a fitness application. For example,
Wahoo fitness, Endomondo, Runtastic, Starve, RunKeeper,
Cyclemeter, 321Run, BLE Heart Rate Monitor, MapMyFitness,
MapMyRide, etc…
Step 4. Pair the Bluetooth Heart Rate Transmitter with the fitness
application in the application settings.
Note:
Some applications may not be compatible. Check the published
specifications.
Remark:
1. Every Bluetooth smart device has its setting and operating method, how
to pair with the chest belt, please refer to the devices’ user manual.
2. Bluetooth smart can be used simultaneously. There’s no interference
problem.
MAINTENANCE OF THE ELASTIC STRAP
The textile strap can be washed in delicate machine wash at +40°C/104°F
with most common laundry detergents. Use of detergents with optical
brightening agents, detergents with bleaching agents, soap or fabric
softener is not recommended. Use of a laundry pouch is recommended.
Machine washing has less variation than hand washing and for this reason
the machine washing is recommended instead of hand-washing.
★ The strap does not resist soaking，dry - cleaning or bleaching.
★ The strap should be dry flat, hang dry or drip dry.
NOTICE:
1 .Wet strap should not be stretch unnecessarily. Strap does not tumble
drying and should not be wring dry. Ironing and pressing with heat are
forbidden.
2. Detach the connector from the strap and rinse the strap under running
water after every use.
3. Sweat and moisture may keep the electrodes wet and the transmitter
activated. This will reduce the transmitter battery life.
4. To keep the product best performance，please wipe out the sweat on
metal buttons with clear water to avoid rusty, causing bad transmission.
TROUBLE SHOOTING:
No Heart Rate or “ZERO” Display
★ - Re-wear it as instructed.
★ - Stay away from power lines or other electromagnetic sources.
★ - Moisten the electrode sensing area of the textile strap.
★ - If there’s no heart rate value display, please take out the battery and
wait for about 1 minute, then re-install the battery.
★ - Avoid using the device outside of the following temperature Range
0°C ~ 50°C (32°F~122°F), slow or black display may occur.
