About our Set-up & Optimize Service
With Scanner Master's exclusive Set-up & Optimize service we see to it that your TRX-2 is fully updated and ready to use for your area, perfect for your own use and especially perfect for a gift. First we optimize the internal database by updating the frequency library, which changes daily.
We will also check and install any firmware updates to the TRX-2 before the radio ships. (The firmware is the operating system for the radio which may have been updated or tweaked by the factory following its production in Asia.)
Scanner Master will then build a Scan List for the customer (based on the ship to address of your order), or for the area in which the scanner will be used if the customer specifies a different city and county (for example if the radio is given as a gift). Scanner Master will also pre-tune the radio by entering the end-users zip code.
Note that this service will add approximately 7 to 14 business days for processing before the radio will be shipped.
(The benefit of this Scan List work is that we insure that the most important data to the user is readily accessible as often times, if the database for the end user's area hasn't been completely prepared with what's known as "geo-tagging" then some or all of the local agencies will not activate for scanning. Scanner Master insures that this will not be the case.)
