Introduction
This manual provides detailed instructions for the proper setup, operation, and maintenance of your Omron HJ-113 Pocket Pedometer.

Product Overview

Front view of the Omron HJ-113 Pocket Pedometer. It features a black casing with a light blue display area. The display shows '10258 steps' and 'PM 12:03'. Below the display are three primary function buttons: 'SET', 'MEMO/▲', and 'MODE'. Three smaller blue circular buttons are located at the bottom of the device for navigation and selection.
Key Features:
- Dual-axis sensor for accurate step counting regardless of placement.
- Measures steps, aerobic steps, distance, calories, and fat grams burned.
- 7-day memory for tracking progress.
- Integrated clock display.
- Automatic daily reset at midnight.
Setup
1. Battery Installation
The Omron HJ-113 Pedometer requires 1 AAA battery for operation. Locate the battery compartment on the back of the device. Open the cover, insert the AAA battery according to the polarity indicators (+/-), and securely close the cover. Note: Some internal components may use a non-replaceable CR2032 battery; however, the user-serviceable battery for primary function is AAA.
2. Initial Settings
Upon first use or after a system reset, you will need to configure the following settings:
- Time: Use the 'SET' button to enter time setting mode. Adjust hours and minutes using the 'MEMO/▲' button and confirm with 'SET'. Ensure AM/PM is correctly selected.
- Weight: Input your body weight. This is crucial for accurate calorie and fat gram calculations.
- Stride Length: Measure and input your average stride length. To do this, walk 10 steps, measure the total distance, and divide by 10. This ensures accurate distance measurement.
Refer to the on-screen prompts and use the 'SET' and 'MEMO/▲' buttons to navigate and confirm each setting.
Operating Instructions
1. Wearing the Pedometer
The Omron HJ-113 can be worn in various ways due to its dual-axis sensor:
- In your pocket: Place the pedometer in your pants or jacket pocket.
- In your bag: Place it inside a bag or purse.
- Clipped to your hip: Use a compatible clip (if included or purchased separately) to attach it to your waistband.
Ensure the device is stable and does not swing excessively for the most accurate readings.
2. Navigating Modes
Press the 'MODE' button to cycle through the different measurement displays:
- Steps: Displays the total number of steps taken.
- Aerobic Steps: Shows steps taken during continuous, brisk walking.
- Distance: Displays the total distance walked in miles or kilometers.
- Calories: Indicates the estimated calories burned.
- Fat Grams: Shows the estimated fat grams burned.
- Clock: Displays the current time.
3. Viewing Memory
The pedometer stores up to 7 days of activity data. Press the 'MEMO/▲' button to review past daily records. Each press will cycle through the previous days' data.
4. Automatic Daily Reset
The Omron HJ-113 automatically resets all daily activity data (steps, distance, calories, fat grams) to zero at midnight (12:00 AM) each day. This ensures a fresh start for tracking your daily progress.
Maintenance
Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water. Keep the device dry.
Storage
Store the pedometer in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is advisable to remove the AAA battery to prevent leakage.
Troubleshooting
Inaccurate Step Count
- Ensure the pedometer is worn securely and does not swing excessively.
- Verify your stride length setting is accurate.
- Avoid sudden, jerky movements that are not part of walking, as these can sometimes be misinterpreted as steps.
Display Not Working / Device Unresponsive
- Check the battery. Replace the AAA battery if it is low or depleted.
- Ensure the battery is inserted with correct polarity.
- Perform a system reset.
System Reset
If the device malfunctions or you wish to clear all data and settings, a system reset can be performed. Locate the small reset button (often recessed) on the back of the device. Use a thin, pointed object (like a paperclip) to press and hold the reset button for a few seconds. This will clear all data, including time, weight, stride length, and memory, requiring you to re-enter initial settings.
