Also, look at Reg. CC.
http://www.bankersonline.com/regs/229/229-18.html See paragraph (c).
Here's the corresponding official staff commentary to 229.18(c).
C. 229.18(c) Automated Teller Machines
1. This paragraph sets forth the required notices for ATMs. Paragraph (c)(1) provides that the depositary bank is responsible for posting a notice on all ATMs at which deposits can be made to accounts at the depositary bank. The depositary bank may arrange for a third party, such as the owner or operator of the ATM, to post the notice and indemnify the depositary bank from liability if the depositary bank is liable under ยง229.21 for the owner or operator failing to provide the required notice.
2. The notice may be posted on a sign, shown on the screen, or included on deposit envelopes provided at the ATM. This disclosure must be given before the customer has made the deposit. Therefore, a notice provided on the customer's deposit receipt or appearing on the ATM's screen after the customer has made the deposit would not satisfy this requirement.
3. Paragraph (c)(2) requires a depositary bank that operates an off-premise ATM from which deposits are removed not more than two times a week to make a disclosure of this fact on the off-premise ATM. The notice must disclose to the customer the days on which deposits made at the ATM will be considered received.
