Update the firmware on your scanner!

Why would you want to update the firmware on your scanner, and how do you do it?
First, let’s explain WHAT firmware is. Firmware is the operating system of your radio, it works behind the scenes and tells the radio how to deal with things like keyboard inputs, frequencies, etc. Just like your computer or phone has an operating system (Like Windows 10, iOS etc.) scanners do too. Remember, scanners these days are miniature computers; they work much in the same way.

Firmware updates are released for a couple reasons. They either fix a problem or add/change features. Sometimes they do both. As an example, the BCD436HP’s most recent firmware update added the ability to add ProVoice and DMR digital protocols, before that firmware updates addressed an issue with clock settings.

When updating firmware one must follow ALL instructions CAREFULLY! You have the possibility of “bricking” your radio if you don’t do it right. This means that your $500 scanner may now be more useful as a brick than a radio… Follow the provided instructions to the letter and make sure that the program and firmware file you use is intended for your radio. The firmware for the PRO106 will not work on the WS1040!

Before trying to update the firmware on your radio make sure you have properly downloaded the firmware file itself as well as the installation program (if needed) BEFORE you start. If you do not have a replacement firmware file to install do not start the process since this erases the existing firmware to make the radio ready for the new version. No new version means no radio once you get going.

Some radios firmware updates are easier than others. The HomePatrol type radios use a program called Sentinel to check for new firmware versions and install them (easy, safe). Other Uniden scanners use a “Bearcat Version Updater” program to install a new update. GRE/RadioShack/Whistler scanners also use an application to install new firmware versions (nerve-wracking maybe).

What they all have in common is that they require a computer running Windows to update. (You can do it with a Mac running Windows with Parallels, Fusion, Bootcamp etc.) You also need the appropriate cable to connect from your computer to the radio. This is usually done via USB but some older radios use a Serial port.

Before updating your firmware make sure you have the following on hand:
• The radio you want to update
• The proper cable for your radio, along with the drivers already installed (if needed)
• The Firmware Updating program appropriate for your radio
• The actual firmware file itself (Imperative!)
• A strong sedative or plenty of alcohol to calm your nerves (optional)

Follow the instructions included with the firmware update TO THE LETTER. Make sure your radio and the computer can communicate properly. If you have programming software for your radio then read it first and save the programming file just in case you need to restore it to the radio. This also ensures that the radio and computer can communicate.

We also suggest that you check the RadioReference forum for your radio to see what other people’s experiences have been. Reading about someone else’s mistake is a lot easier than trying to fix your own.

Owners of PRO651 and PRO652 scanners that had tried to update their radios’ firmware versions had issues since no firmware updates were available until recently. Now one can download them and install them so previously bricked radios can be reincarnated.

ScannerMaster can update the firmware on many different models of scanners. Download the Hometown Programming Form for your radio and check the Firmware Update option if you would prefer our expert programmers to do this for you. We keep them heavily sedated all of the time already so their nerves are steady. Firmware Updates for “Zip Code Scanners” (HomePatrol, 436/536 and the TRX/WS1080/1088/1095/1098 series scanners) is included with the Setup and Optimize package already, it is an extra cost option for other scanners. If you aren’t sure call us and we will let you know.

Scanner Tip: Care and feeding of scanner batteries

If you use handheld scanners then you have to manage batteries. Most scanners come with or use rechargeable Nickel Metal Hydride cells, often abbreviated to Ni-MH. There are still some older Nickel Cadmium (“Ni-Cad”) cells still around. There is also a newer technology called Lithium Ion (“LI”). If you still use one of the older scanners with composite battery packs (like the BC250D or BC296D) these likely use or NiMH battery packs.

Current scanners almost always use “AA” sized batteries. AA Ni-MH batteries are very common these days and can be found almost anywhere and are also used in a wide variety of different applications. LI batteries are more expensive but are lighter in weight and provide longer life in many instances.

If you charge your batteries in the radio then remember that it is likely set up for Ni-MH. If you use Ni-Cad or LI cells then the charge times will be different. If your radio supports altering charge times then you could change it to match.

Whatever you do make sure that ALL the cells in the radio are the same! Do not mix different types of cells. Also make sure that you do not try to charge alkaline cells like Duracell or Ray-O-Vac’s! This is an easy way to blow things up and make nasty things happen. If you do this warranty will not cover you and the repairs are on you.

If you want to use rechargeable batteries that are different than the ones that came with the radio then consider a separate charger. This would allow you to manage 2 or 3 sets, one for current use and another for standby when the current ones are depleted and a third set in the charger. Make sure the charger you use is appropriate for the batteries you use.

What about Alkalines? Alkaline batteries, such as Duracell’s, Energizer or Ray-O-Vac brands, are great for scanners. You do need to make sure that you do not try to charge them. On many Uniden scanners there is a tiny switch inside the battery compartment that you can select Alkaline or Ni-MH. If you select Alkaline the radio will not attempt to charge batteries in the radio. If you have a RadioShack, GRE or Whistler handheld scanner then the yellow battery holder will charge your batteries when the radio is plugged into an outside power source, so do not use the yellow holder for alkalines. The black battery holder is used for alkaline batteries.

One other thing to consider is that rechargeable batteries produce a slightly lower voltage than alkaline ones do. Typically rechargeable cells produce 1.2 to 1.25 volts compared to 1.5 volts for alkalines at full charge. Usually this is not a problem; the extra quarter-volt per cell is not going to burn up your radio. Using higher voltage alkaline cells will allow the radio to run a bit longer before the battery warning starts.

Here is a little hint for users of later Uniden scanners: You can see how many volts your battery has at any time by pressing the rotary knob down while scanning. Make note of the voltage with fresh cells and the voltage when the battery warning starts. This will give you a good idea of when to expect the need to change or charge the batteries.

I always try to keep an extra set of batteries handy when I am out and about. Save those little battery boxes or use something to keep the batteries from shorting and bouncing around. I use a prescription bottle; larger ones are perfect for 3 or 4 AA’s! I can then toss that in the glove box. Just remember to take off the label so the world doesn’t find out what meds you take. Do they make a pill that will cure a scanner addiction?
