Setup
Before first use, or after replacing the battery, you will need to set up your pedometer.
1. Battery Installation
The Ozeri 4x3runner uses one CR2 lithium battery. If the battery is not pre-installed, open the battery compartment on the back of the unit, insert the battery with the correct polarity, and close the compartment securely.
2. Initial Settings
Upon powering on, the pedometer will prompt you to enter your personal data for accurate calculations. Use the 'MODE' and 'MEMO' buttons to navigate and adjust values, and 'START/STOP' to confirm.
- Set Time and Date: Adjust the current time (12/24 hour format) and date.
- Enter Personal Information: Input your weight and stride length. Accurate stride length is crucial for precise distance and calorie calculations. The pedometer allows programming both walking and running stride lengths.
- Set Daily Goal (Steps-2-Goal): Define your desired daily step target. The pedometer will track your progress towards this goal.

Maintenance
Proper care will ensure the longevity and accuracy of your Ozeri 4x3runner Pedometer.
Cleaning
Wipe the pedometer with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the device. Do not use abrasive cleaners or solvents.
Battery Replacement
When the display becomes dim or the device stops responding, it's time to replace the CR2 lithium battery. Follow the battery installation steps in the Setup section. Dispose of old batteries responsibly according to local regulations.
Water Resistance
The pedometer is water-resistant, meaning it can withstand splashes and light rain. It is not designed for submersion in water. Avoid exposing it to heavy rain, showering, or swimming.
Troubleshooting
If you encounter issues with your Ozeri 4x3runner Pedometer, try the following solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Pedometer not counting steps accurately. | Ensure your stride length is correctly programmed. The device filters out vibrations and only begins counting after detecting a sequence of continuous steps (typically 10 steps). Ensure consistent movement. |
| Display is dim or blank. | The battery may be low or depleted. Replace the CR2 lithium battery. |
| Cannot switch modes or buttons are unresponsive. | Try removing and reinserting the battery to perform a soft reset. If the issue persists, contact customer support. |
| Data (distance, calories) seems incorrect. | Verify that your personal information (weight, stride length for both walking and running) is accurately entered in the settings. |
