Question: how do i open the VIZIO XRT302 battery compartment?
Document: (The vendor had replied that it would work, and kindly told me if it didn't, I could send it back. )To my utter delight, VIZIO WAS WRONG! The XRT302 remote works fine with my e500i-A0 smart TV, QWERTY buttons and all! I notified VIZIO - but who knows how they had erroneous information in the first place, or whether they will correct the information they give out?This ended well!
IT WORKS LIKE A CHARM! VIZIO should have included THIS remote with the original TV!After ordering the remote I happened upon a laborious path to VIZIO Tech Support and emailed them a inquiry about whether this QWERTY model XRT302 would work with my model e500i-A0 TV. They replied that they regretted to inform me that the QWERTY buttons would NOT work, only the &#34;regular&#34; remote control buttons on the other side.
It was good was hoping I flipped open not just buttons on both sides but it does the job it was intended
Was the right one and just put battery and started working.Didnt have any problems and every thing worked on the remote.
Nice remote, it feels weird with the back keyboard at the beginning, and is difficult to open to put batteries in..  but starts working once you put batteries in without programming.
This is so much easier to use with my VIZIO Smart TV. I was worried about the compatibility. No set up required. Just add batteries.
I brought this as a replacement because mine was damaged and the remote works great with my tv and i purchased it cheaper than I would have on the VIZIO web site.
How &#34;smart&#34; is that? The best solution, of course, is to buy an inexpensive spare remote for the TV that INCLUDES the QWERTY buttons - like this one.Searching for such a remote by my TV model number, I came across this same remote, advertised often by the same vendor, for differing VIZIO TV models at different prices!
This item was not new. It's battery door clip that keep it in place was broken off, and it had a labeling device sticker that said &#34;Remote&#34; on said door. The remote works, but it isn't new as it's title would have you believe.
We bought a VIZIO e500i-A0 smart TV (50&#34;) on black Friday after thanksgiving at a major retailer. The remote that came with it was identical to this one, except that it did NOT HAVE the QWERTY buttons on the back. One of the points of having a &#34;smart&#34; TV is that you can use streaming services like Netflix without a separate computer or Roku type device.
Answer: Below the numerical pad is the battery compartment. Just push and slide down.
