Model: UNIDEN SDS100

To upgarde to SUB V1.03.03.   

This test version changes 4FSK Filter to Least Square Method to improve Motorola Type II.
It is not limited for test the Motorola Type II issue, also for people who experience poor reception of other digital systems.

Caution:
1. This sub firmware is not compatible with Main V1.21.00 and older version.
2. The SUB V1.03.03 cannot be overwrite to V1.03.02 via Sentinel because V1.03.03 is a higher version than the Sentinel server has. To revert to current officall version V1.03.02, you need to do it the same way instead of using Sentinel.

3. Do not put different firmware versions on the SD card at the same time. If there are different versions, the upload will not start or will not be uploaded correctly, so please be sure to upload only one version. 　

If you accidentally delete two dat files already included in the SD card that are not related to Firmware, SDS100 will not start properly. If you accidentally delete these files, you can restore them by executing "Clear User Data..." via Sentinel, but all User Data will be lost.


Please back up contents in SD card and your settings via Sentinel just in case.
Please make sure the battery is fully charged before starting.
