Model: UNIDEN SDS200

To upgarde to SUB V1.03.04. (and Main V1.23.03A = OPTION*)

This test version reverted the conditions for resetting the FS Counter to the method before Waterfall Fall version. 
It is not limited for test the Motorola Type II issue, also for people who experience poor reception of other digital systems.

*Main V1.23.03A adds a function to monitor which demodulation (IQ or 4FSK) method is selecting by the SDS200, and the infromation displayed instead of the time display. This Main firmware version is no need to use unless there is a problem.

If the symptoms still persist, please update Main firmware to this version and let us know which method SDS200 is using while the symptoms are occurring. 
> To start monitoring, turn on the power while holding down the "AVOID" key on the SDS200. 
This mode will be canceled when the power is reset.

Caution:
1. This sub firmware is not compatible with Main V1.21.00 and older version.
2. The SUB V1.03.04 (and Main V1.23.03A) cannot be overwrite via Sentinel because these are higher versions than the Sentinel server has. To revert to current officall version SUB V1.03.02 (and MAIN V1.23.03), 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, SDS200 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.
