RE: ATCB007492 – Original Equipment/Single Certification Applications

FCC ID: GQ4-42T & IC: 1470A-23T for TRW Inc.

The following is in response to the comments made on the above referenced application.

1. In the Alert Mode for this transmitter, please clarify how long each word lasts and how long of a period
exists between each word so I can determine if I need to list Section 15.231 on the FCC grant of
Certification if the transmitter still operates under Section 15.231(e) of the FCC Rules during the Alert
Mode. The operational description only states that it transmits 8 words every four seconds for 1 minute
but it doesn’t mention the length of each word or transmission and the period between each word or
transmission. This information was not provided in the test report either.

Alert modes fall under FCC 15.231(a)(4), and may operate during the pendency of the alarm condition
regardless of duty or mode. In this case, each word is identical in length and staggered period as those
shown in the report under normal operation.

2. Please confirm that the EUT was rotated 360 degrees and the measurement antenna was raised and
lowered between 1 and 4 meters to maximize radiated emissions from this device. The FCC is no longer
accepting a statement that the test procedures followed are those contained in ANSI C63.4-2003. It would
be helpful to add a sentence to your test report format in Section 5.2 right after the statement about
testing in 3 different axes to clarify the procedures used to maximize radiated emissions.

The test report has been updated to further detail the test procedures employed.

3. I do not think the Canadian representative attestation letter is acceptable because the Canadian
representative is listed as Mr. Bob Millett on the IC application form but Mr. Scott Relf has signed the
Canadian representative attestation letter. Further the address on the Canadian representative attestation
letter does not agree with the address on the IC application form for the Canadian representative. You
can either provide me with another Canadian representative attestation letter or merely state that you are
willing to wait for IC to contact the Canadian representative before listing this device on the REL in
Canada. (See the sample Canadian representative letters attached). Please let me know how you wish to
proceed.

The attestations and application forms have been updated to reflect Mr. Scott Relf as the Canadian
representative.
