Comment on Undo codes for Japanese elevator floor buttons

Comments

According to the chart, if you’re on an elevator made by Mitsubishi, Matsushita, Toshiba, or America’s Otis, you can cancel a floor by quickly tapping twice (“double-clicking”) on the corresponding button.

If I had to guess I'd say in the US it's nearly always Otis or Schindler elevators that I'm riding. Do the Otis elevators installed in Japan have this feature but the Otis ones in the US lack the feature? I've never tried double-clicking to undo.

I have had it work once in the US out of more than 10 attempts.

   It did also work on a cruise ship, which was good because kids had hit all the floor buttons and run.
Double tapping or holding a lighted button works to cancel all the time in Japan.

There are other button codes. Once, when I was in Japan and we waited at 8am for a lot of full elevators going past opening up the person I got in with (to another nearly full elevator) held down the G button for several seconds, all of the floors flashed and we went straight down without stopping. I asked as we got off, and apparently on other elevators this floor bypass can be done by holding down the close door button the entire trip.

G button?

The "G" button often represents the Ground floor (aka "first floor" here in US). Sometimes in the US 'G' indicates "Garage".

Yes, and my memory may be faulty. It could have been a 1.

Often in the US it's also the P button(s) for Parking.
