I downloaded the file, and it works. On a side note. Am I required to assign a quick key and/or number tag ?
No. Those are optional.
Quick keys let you toggle a favorites list (on the Home Patrol database scanners such as the x36HP 7 SDS series) on or off instead of having to access the menu, select "Set Scan Selection", then use the sub menu to turn a specific Favorites on or off (not being scanned). With a quick specified for the list, you can turn that system off (no longer being scanned), or "on", enabling a list to now be included in your current session.
Quick keys can also be specified for specific systems, and for the departments (as well as sites for trunked systems) so that you can turn them on, or off depending what you want to hear. Say, for example, you have three different cities programmed, all of then assigned a QK (quick key). You hear a major incident, of some type, being dispatched for units in 'city one'. It really has your interest, and you want to, temporarily, ignore routine activity in the other locations. You simply enter their QK numbers (one at a time) to turn them off for now. Once whatever peaked your interest is over, you can easily turn those systems back on & resume normal listening.
Let's say that your 'major incident' that caught your attention (as well as having you temporarily turn off other systems with a quick key, was a very large fire. You have a number tag programmed for the fireground channel most often used. You can use the number tag to jump straight to that channel, rather than waiting for it to come up while scanning, or going to manual (hold) mode and using the scroll knob to progress to that channel.
There's much more info, including how to set up & use number tags on the Easier to Read manual
page for your scanner. When on the initial landing page for your scanner model, hit <Ctrl><F> (the control button on your keyboard, as well as the letter F), both at the same time. That brings up a box in your browser for a search. Enter Number Tag in that box & press Enter. That will let you see all the references to number tags. The link for the section "Using Number Tags" is
here.
