you can use the zip code feature
The zip code method (using location, range, and specifying service types) can be used, but it's only going to be as good as the database version in the scanner.
I also need any help available for programming my bcd436hp . But can I program manually as I don't have a computer/laptop at this time., my main issue is trying to program the p25 trunking system..
Did you just receive the scanner, new from an online dealer? Or was it a previously owned scanner, from another individual?
If you just received it, whether new, or not, the database may be well out of date. If that's the case, using your location may not include what is actually in your area.
Press the Menu key (that's the lower key on the left side of the scanner).
From the menu, select the menu line to 'Manage Full Database' (Press the
E (enter) key to select)
At the next sub-menu, select Information
The next screen will show the date that the database in your scanner was created,
Mine was updated last week, If you see a date months, or even years, ago, you're going to miss a lot of what might be available. Even though you, yourself, do not currently have a PC, see if someone you know will install Sentinel, and help you update the database. Then, they can connect your scanner to their PC & send the latest database version to your scanner. There is no charge for installing Sentinel, and once they help you get updated, then they can uninstall Sentinel if they desire to do so. Long term, you would be better off with your own PC, laptop or desktop. As long as it can connect to the internet, you don't need the latest, greatest, fastest PC. Sentinel does not require a lot of system resources such as memory RAM or a super fast processor.
