Frequency is measured in hertz (Hz). A person who has hearing within the normal range can hear sounds that have frequencies between 20 and 20,000 Hz. The most important sounds we hear every day are in the 250 to 6,000 Hz range.
An issue date was added, and cheques may not be valid a certain amount of time after issue. In the US and Canada a cheque is typically valid for six months after the date of issue, after which it is a stale-dated cheque, but this depends on where the cheque is drawn; in Australia this is typically fifteen months.
The check is then considered stale. Do not try to deposit a stale check as our bank carefully checks both endorsements and time requirements and will refuse to honor it. If you have a stale check, return the check to our office for the check to be reissued (attention of Eileen). If a creditor receives a check without their account number printed on the check, the creditor should make a copy of the check listing the account number, and mail it to the Chapter 13 Trustee Office.
