In a notification, RBI said, "The message regarding non-availability of cash in ATMs should be displayed before the transaction is initiated by the customer."
Such notices may be displayed on the screen or in some other way.
Banks should also highlight the ATM ID within the premises so that customers can quote it while making complaints or suggestions, the notification added.
According to PTI, RBI asked banks to make forms available within the premises for filing ATM complaints and also to display the names and phone numbers of officials handling complaints.
"This will help in avoiding delays in lodging complaints," it said.
To help customers to file complaints, banks have been advised to provide sufficient toll-free numbers, prominently displayed at the ATM premises or bank's website, PTI report said.
