Motorola Display with Sun Glasses On

[kb1dog]

Ever try to read your radio display with sunglasses on? Why would you do that? Well, you could be driving, or working outside security or manufacturing. Well, it turns out the CP100d with Display has some incompatibility with polaroid sunglasses. Strange patterns show up that block the text within the display. I tried my best to show the impact on the enclosed JPEG. Notice the black clouds to the right and left, and a black horizonal black wavy line. With sun glasses on, compared to without sun glasses. And to be fair, my Lexus has similar problems when looking at some of its displays, such as the FM RADIO DISPLAY. This could just be a defective display, or maybe all Motorola displays have this problem? But it needs to be fixed right away because in an emergency situation I need to be able to quickly determine what channel I am on. Thoughts? Wouldn't you think Motorola would ever test their radios with sunglasses on?

Any display that has a built in glare reducer (polaroid lens sheet) will be incompatible with polarized sun glasses. Looks like its back to the Baofeng for you. Low tech we can count on!

Yeah, polarized glasses will do that.
Won't work when you are wearing them but take them off and try rotating 90º and it should change.

+1 on all of the above. Plus when I have my 7550e and I rotate the radio, the display goes from green to purple depending on the angle lol.

I have had the same problem with my smartphone (currently iPhone 12 Pro). I have to remove my sunglasses (aren't they all polarized now?) to be able to see the screen no matter what it's used for (NOT calling with the phone while in motion). I guess it would also apply to any LCD screen on two-way radio equipment.

Optometrists will sell FAA pilot approved sunglasses [non-Polarized] without a prescription.

I had the same problem with a watch that had an LCD display, telling me it's probably not an intentional problem created by the equipment manufacturer...

Simple solution! Rayban sells non-Polarized sun glasses.

So do most 7-11's!

And go get yourself some cheap sunglasses"

I can guarantee you the sunglasses at Dollar Tree are not polarized if you don't mind wearing pink and green sunglasses.

It's never been an issue with my apx 7000 because I only wear sunglasses in the car and I put the display and keypad up against the back of the plastic case that I use the belt clip to attached to a proclip. Only scan maybe 2 or 3 items.

I definitely know it is a big issue with the GRE Whistler scanner displays.

For whatever it might be worth, my optometrist once put my cheap sunglasses between the projector and the screen (the set-up used to project letters that patients would read during an eye exam) and I was surprised at the amount of distortion that was created by el-cheapo glasses...also my doctor emphasized the importance of proper UVa & UVb filtering (good glasses will be tagged with numbers)...

That reminds me over a story from over 10 years back. So long ago that I was still using a Nextel! I had just come on duty and one of the guys hits me up on Direct Connect and asks, "What is wrong with the MDCs this morning?" I asked for more details and he said he could not see the screen when he went to sign on to the CAD. So, we made a quick meet. I sat in his car and powered up. The computer was fine. Then, I look at him, he is wearing those prescription eyeglasses with the magnetic clip on sunglasses. (I had them years ago, before I had the Lasik procedure.) So, I said, "Kevin, take off your clip-ons." He removed them and said, "Hey, what is going on?" because he could see the screen just fine, then. I explained the whole polarity deal to him!

Non-polarized sun glasses are the solution. There are plenty of high quality non-polarized sun glasses to choose from that have proper UVa and UVb filtering, no need to hit the dollar store for them.

Certainly it is a solution. But I am not planning to adjust my glasses to meet the requirements of Motorola radios.

yeah, UVa & UVb protection is probably a higher importance...

I've worn a pair of amber WallyWorld sun/safety shooting glasses for years now. Haven't had problem one wearing them while looking at any type of electronic display.

73 to ya...

Just me...
