I just bought the BCD436HP about 2 weeks ago and from what i see in the scanner the last update was done in April
so i need to get the update done .
Now i am just a little confused i thought to update the scanners Sentinel database on the sd card all i did was log in to
sentinel go to the top tab update and click on update master database and follow the directions and done .
not sure what you mean by update the Home Patrol Database on your PC first and then when you click write to scanner
I do have the latest version of the sentinel on my pc if that's what you mean down loaded it a few days ago so i could look around and try to get familiar with it (that will take some time)
Sentinel does two things.
1) Updates the firmware on your BCD436HP. As of today's writing,
the most current version is 1.26, released 04/20/2019.
2) Updates the HPDB on your BCD436HP. You download the updates first to your computer (Update HPDB), make your adjustments to your favorites list, etc on your computer. Then, you "Write To Scanner", this sends the favorites that you created/modified/updated and then it sends any HPDB updates.
The key thing is to look on the lower left hand corner of Sentinel to see what version of the HPDB that you have and simply performing the update if it's not the most recent. You want to work with the up-to-date data.
To check the HPDB on your Scanner, it's under Menu, Manage Full Database, and then select Information. It will show you the "dB Version." This is what is "onboard" that allows you to use the nationwide zipcode feature and any favorites that are made manually with the scanner.
The highly touted
BCDX36HP Sentinel Easier To Read Manual is a good resource.
