Schrader has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Type of Confidentiality RequestedExhibit Permanent Confidentiality:Schrader requests the exhibits listed above as permanently confidential be permanently withheld from public review. Short-Term Confidentiality (FCC Only):Schrader requests the exhibits selected above as short term confidential be withheld from public view for a period of 45 days from the date of the Grant of Equipment Authorization and prior to marketing.

SCHRADER ELECTRONICS.LTD.. Renault Edison HS SNAP IN 433Mhz. Product Specification. he TPMS Transmitter is installed to the valve stem in each tyre of a vehicle. The unit measures tyre pressure periodically and transmits this information by RF communication to a receiver inside the vehicle. In addition, the TPMS Transmitter performs the following functions: Determines a temperature compensated pressure value. Determines any abnormal pressure variations in the wheel. Monitors the state of the Transmitters’ internal battery and informs the receiver of a low battery condition.
