Multi Request Long Range Acoustical Device


From: Curtis Waltman

To Whom It May Concern:

Pursuant to the Illinois Freedom of Information Act (5 ILCS 140/1 to 11), I hereby request the following records:

This request deals with the Long Range Acoustical Device (most commonly referred to as an LRAD) manufactured by the LRAD Corporation. I am asking for:

-Contractual documents. Examples of this are invoices, purchases orders, contracts, loan agreements, procurement documents etc.

-Records of communication (letters, emails.) The domain for LRAD Corporation is lradx.com. The general sales email is sales@lradx.com.

-Any training documents or guidelines for the use of the LRAD. This is especially important due to the ability for the LRAD to leave long term hearing damage in those that are exposed to its warning mode.

-Any utilization logs for this device.

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 5 business days, as the statute requires.
