Device Reset & Manual Firmware Upgrade Guide

Precaution when upgrading firmware:

• Phone must be connected to stable internet connection.
• Phone and watch are within the Bluetooth range - the closer the better.
• Phone is ONLY paired with ONE KoreTrak watch.  Turn off any paired Bluetooth devices such as earbuds, speakers and any other Bluetooth wireless device.
• Phone and watch are at least 50% charged, you will not be able to update the firmware with less than 50% charge.
• Both devices can be charging during the entire firmware update.
• During the upgrade process, refrain from moving from one location to another causing potential Bluetooth interruption and internet data transmission.
• Refrain from making phone calls or messaging during update process as those programs can interrupt connection.

Hardware Requirement:

1. KoreTrak fitness watch.

2. WiFi and Bluetooth enabled smartphone (with installed iOS with DayBand App 1.0.15 or Android with DayBand App 1.3.2).
   
   

Preparing for the Firmware Update:

1. Your smart phone should be at least 50% or charged. Low battery will affect connection speed, transfer speed and could cause accidental power off during the update process.

2. Your KoreTrak fitness watch should be at least 50% charged. Low battery could cause accidental power off during the update process.

3. Make sure your smartphone has stable internet connection via 5g/4g LTE or via WiFi connection.
