• Activate the heart rate detection mode. A green pulse sensor will light up on the back of the watch or band if it’s operating.

How to Activate Heart Rate Detection

PS-500

Press the A button. Heart rate detection starts and the progress bar will display.

PS-100

Attach the PS-100 to your wrist. Heart rate detection starts when you move the PS-100. All blue LEDs will light up in the sequence shown below when your heart rate is detected.

• Press the B button until the PS-500 displays the time, then press the B button again to hide the heart rate display. The PS-500 is now in privacy mode. To see the heart rate again, press the B button to scroll through screens until the time screen appears again.
  The process will stop when the Pulsense device is still for 10 seconds. With the PS-500, you can also press the B button to stop the process.

• When the device is taken off during pulse measurement, pulse information will not be entered into the pulse sensor.
  *"---" is displayed on LCD when there is no pulse information.
  Specification is set to stop the measurement with no pulse information and no device movement (no acceleration is added) for 1–6 minutes and the device is considered as taken off from the arm.
• When there is no device movement for 10 minutes after the pulse measurement has stopped, LCD on PS-500 turns off and the device goes into power save mode.
  Power save mode is cancelled and LCD turns on when the device is moved.

Try the following:

• Make sure it fits snugly around your wrist and that it does not touch your ulna bone.

• Make sure you’re wearing the device. It will display (---) when it’s not on your wrist.
• Position your arm below your heart. Do not cross your arms.
• Certain types of light can affect the pulse sensor. If (---) is displayed on the screen, keep your body and arms still for a while. Your device will display your heart rate again.

• This indicates your Pulsense device isn’t detecting your heart rate. This can happen during vigorous exercise. The heart icon will become solid again when your movement slows down.

• Can be worn on either arm
  PS-100 can does not have a set orientation
  　* The direction the “Epson Logo” is facing will not affect measurement
• The sensor on the underside of the device should be on the same side of the arm as the back of the hand when worn.
  Make sure that it is worn further up the arm than the ulna bone.
• When fastening the band, tighten until the device fits snugly without shifting.

• While in airplane mode, remove the device from arm and tap the top of the device repeatedly.

• Stay rested until the device detects pulse.
• Move your arm below your heart.
• Avoid conditions such as crossing your arm that block blood flow.
• Blood flow is reduced and pulse detection becomes more difficult when ambient temperature is low.
  Exercise in warm clothing when you get low temperature error.

• Pulse is difficult to detect and measurement error occurs when band is not secured properly (too loose/too tight).
  Adjust the band so the device is not wobbly and does not move easily.
• When "Low temperature error" is displayed, raise the wrist temperature by wearing warm clothing, etc.
  Low wrist temperature causes reduced blood flow and pulse becomes difficult to detect.

• Measurement cannot happen when band is not secured properly (too loose/too tight).
  Adjust the band so the device is not wobbly and does not move easily.
• Pulse is hard to measure when you squeeze your hand tightly.
• Pulse may be hard to measure when a shock is applied to the hand such as clapping, holding and letting go off of an object.
• Stable measurement cannot occur when the device is on the elbow bone.
  Move the device to shoulder side.
• Pulse is hard to measure when the arm is held up high or being crossed.
• Measurement may be difficult in exercises other than the recommended.

• Measurement may not happen when band is not secured properly (too loose/too tight).
  Adjust the band so the device is not wobbly and does not move easily.
• Pulse may be hard to measure depending on sleeping positions that put pressure on the arm.

• Specification is set to stop the measurement after 1–6 minutes of inactivity, but it might not stop in following conditions:

  1. The device goes into measure ready mode and does not stop when there is a movement from vibrations, etc.
  2. When the device is rested on a surface with an angle that is greater than the set criteria.
  * Rest the device so the side is facing straight down. (It will stop around 15º angle.)

• Depending on the condition when the device is taken off of the arm, it may not be determined as taken off and measurement might continue:

  1. When the amount of light coming into the sensor did not change dramatically.
  2. Taken off in the dark such as while sleeping.

• When the device is stored in a bag without being put into airplane mode, vibrations from movements might trigger the pulse detection.
  Then pulse measurement might start and continue since inside of a bag is dark and the amount of light coming into the sensor does not change dramatically. (120 or 60 RPM will be displayed in the app)

• There may be a difference in pulse rate value when not properly worn.

• When the device has no communication with PC or smartphone, it can record up to 480 hours.
  Measurements after 480 hours will overwrite the old data, so we recommend regular backup communication.
• When the device has no communication with PC or smartphone, 2,480 measurement data can be recorded.

• When the device has no communication with PC or smartphone, it can record up to 480 hours.
  Measurements after 480 hours will overwrite the old data, so we recommend regular backup communication.
• When the device communicates with PC or smartphone, data will be erased.

  Data will remain on the device until next backup communication.

• Yes, calories can be measured.

• [PS-500]

  Measurement result can be confirmed on the device.

• Can be confirmed in Web/smartphone application.

• [PS-100]

  Can be confirmed in Web/smartphone application.

• The device uses your BMR (Basal Metabolic Rate) when it calculates calorie consumption. This is the rate you use when you’re at rest.

• Because calculations are based on the results of heart rate and movement detection, readings may differ from those of other devices on the market.

• Because calculations are based on the results of heart rate and movement detection, readings may differ from those of WristableGPS
  * SF-810 uses the same calculation methods to measure heart rate

• Approximate distances can be measured.
  The body height entered in the profile is used to calculate the approximate length of each step, so measurements should be for reference only.
  Distance = step count x length of step
  Length of step = height x coefficient
  (Coefficient　　Walk = 0.45, Run = 0.5)
• Error tolerance
  Generally within ±10-20%
  May change 30% or more on hilly roads, while wearing a backpack, etc.

• Yes. You can see the count in the PULSENSE View app or the web portal. The PS-500 will also display the count on its screen.

• Steps are counted from regular arm movement of walking and jogging (change in acceleration).
  When regular arm movement (similar to walking) continues, it may be counted as steps.
  Eg: Brushing teeth, using hair dryer, etc.
• It is not counted as steps when arm moves in irregular motion, such as deskwork.
