1. A method of initializing a tire pressure monitor, the method comprising:
- tuning a receiver device at a wheel unit to monitor for first transmissions from an initiation source during a first predetermined time period, the first transmissions being made according to a first criterion;
tuning the receiver device at the wheel unit to monitor for second transmissions from the initiation source during a second predetermined time period according to a second criterion and not according to the first criterion, the second criterion being different than the first criterion;
when the receiver device at the wheel unit initially recognizes one of the first transmissions being transmitted according to the first criterion or the second transmissions being transmitted according to the second criterion, at the receiver device at the wheel unit verifying that the recognized transmission is valid by comparing the recognized transmission to an expected information pattern;
in response to verifying at the receiver device the recognized transmission is valid, sending an indication from the receiver device to a central receiver unit in the vehicle so that a localization procedure can be executed.

Abstract
A receiver device is tuned to monitor for first transmissions at a first time according to a first criterion and to monitor for second transmissions at a second time according to a second criterion. When the receiver device initially recognizes one of the first transmissions being transmitted according to the first criterion or the second transmissions being transmitted according to the second criterion, the recognized transmission is verified as being valid. When the transmission is recognized as valid, a transmission apparatus is activated to transmit an indication to a receiver so that a localization process can be executed.
