3.2 Understanding Smart Sensor Technology

The Omron HJ-203PK utilizes advanced 2D Smart Sensor Technology. This sensor accurately detects walking movements and filters out non-walking motions, such as sitting or standing still, to provide a precise step count. This technology allows for flexible placement of the pedometer.

4. Operating Instructions

4.1 Basic Tracking

Once set up, the pedometer automatically begins tracking your daily activity. It records:

• Steps: Total steps taken throughout the day.
• Distance: Total distance walked or run.
• Calories Burned: Estimated calories expended based on your activity and personal data.
• Fat Grams Burned: Estimated fat grams burned.

The display will cycle through these metrics. Use the 'MODE' button to manually switch between different display modes.

4.2 Using Workout Mode (Activity Tracker)

The Workout Mode allows you to track specific exercise sessions separately from your total daily activity.

1. Start Workout: Press and hold the 'ACTION' button for approximately two seconds. The display will indicate that Workout Mode has started, often with a scrolling bar or specific icon.
2. During Workout: While in Workout Mode, the device will track steps, distance, and calories specifically for that session.
3. End Workout: To end the workout session, press and hold the 'ACTION' button again for approximately two seconds. The workout data will be saved and displayed, then the device will return to normal daily tracking.

4.3 Display Navigation and Buttons

The device features three main buttons for navigation:

• MEMO Button: Used to access and review your 7-day memory data. Press to cycle through past daily records.
• ACTION Button: Used to start and stop Workout Mode, and to confirm settings during initial setup.
• MODE Button: Used to switch between different display screens (e.g., steps, distance, calories) and to adjust values during setup.

4.4 Sleep Mode

To conserve battery life, the device enters 'sleep' mode after approximately five minutes of no button presses. While in sleep mode, the display may show "sleep" or turn off, but the device continues to accurately track your activity in the background. Press any button to reactivate the display.

4.5 Optimal Placement for Accuracy

The Omron HJ-203PK is designed for flexible placement due to its 2D Smart Sensor. For best accuracy, place the pedometer in a pocket (shirt or pants), a bag, or attach it to a lanyard around your neck. It functions correctly whether positioned horizontally or vertically. Ensure it is securely placed to prevent loss.

5. Maintenance and Care

5.1 Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.

5.2 Battery Replacement

When the battery indicator appears or the display becomes dim, replace the battery. Use the provided screwdriver to open the battery compartment. Replace with a new lithium battery (Product Specific, included type). Ensure correct polarity and securely close the compartment.

5.3 Environmental Conditions

The device is designed to operate reliably in temperatures ranging from 10°F to 104°F (-12°C to 40°C). Avoid exposing the device to extreme temperatures, direct sunlight, or high humidity.

6. Troubleshooting

• Inaccurate Step Count:
  Ensure the device is placed securely in a pocket or bag, or worn on a lanyard. While flexible, extreme jostling or inconsistent movement patterns (e.g., very short, shuffling steps) might affect accuracy. Verify your personal data (height, weight) is correctly entered.
• Display Shows "Sleep":
  This is normal behavior to conserve battery. Press any button to reactivate the display and view your current data. The device is still tracking activity while in sleep mode.
• No Display/Device Not Responding:
  Check the battery. The battery may be depleted or incorrectly installed. Replace the battery if necessary, ensuring correct polarity.
• Workout Mode Not Starting/Stopping:
  Ensure you are pressing and holding the 'ACTION' button for the required two seconds to initiate or end the workout session.
• Data Not Resetting at Midnight:
  Verify that the clock is set correctly. The device automatically resets daily data at midnight based on its internal clock.
