If you own a Voltas air conditioner you might get stumbled into this little lock icon on the remote. It drove me crazy as I hit all buttons on my Voltas AC remote to remove the lock. Never ever before had I seen a lock and what confused me even more that nothing has been said about the lock in the user manual.
Fortunately one of my friends work in Voltas and he told me how to remove lock. Just press – and + buttons together and voila, the lock is gone.
The lock is very useful when you do not little kids to turn off the air conditioner or change its settings. Once the lock is placed, no setting can be changed. Just make sure you do not tell them how to unlock it.
