BTR-30N, TR-30N, TR-32N 3 Important Safety Instructions 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 10.Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. 11. Only use attachments/accessories specified by the manufacturer. 12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14.Refer all servicing to qualified service personnel. Servicing is required if the apparatus is damaged in any way, such as: the power supply cord or plug is damaged, liquid is spilled or objects fall into the apparatus, the apparatus is exposed to rain or moisture, the apparatus is dropped, or the apparatus does not operate normally. 4 BTR-30N, TR-30N, TR-32N Table of Contents Important Safety Instructions ....................................3 INTRODUCTION .............................................9 General Description ..............................................9 System Features ....................................................9 Controls and Connections ...................................10 BTR-30N – Front Panel ..........................................10 BTR-30N – Rear Panel ...........................................11 Specifications ..........................................................12 TR-30N - Top Panel ................................................14 Specifications ..........................................................16 TR-32N – Top Panel ...............................................18 Specifications ..........................................................20 INSTALLATION ............................................19 Unpacking ...........................................................19 Antenna Connection ...........................................20 Antenna Polarization ...........................................20 Distance between Antennas ................................21 Antenna Placement .............................................21 Improving Reception and Increasing Range .......23 OPERATION ..................................................25 BTR-30N ............................................................25 Operation .................................................................25 Basic Operational Description ................................25 System Quick Start ...........…

Page 1 of 1 Request for Confidentiality Date: April 19, 2020 Subject: Confidentiality Request for: Bosch Security Systems, Inc. FCC ID: B5DM540 IC: 1321A-BTR30N Pursuant to FCC 47 CFR 0.457(d) and 0.459 and IC RSP-100, Section 9.4, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit ☐ Short Term ☒ Permanent ☐ Not Provided Block Diagrams ☒ Short Term ☐ Not Provided External Photos ☒ Short Term ☐ Permanent ☐ Not Provided Internal Photos ☐ Short Term ☒ Permanent ☐ Not Provided Operation Description/Theory of Operation ☐ Short Term ☐ Permanent ☒ Not Provided Parts List & Placement/BOM ☐ Short Term ☒ Permanent ☐ Not Provided Tune-Up Procedure ☐ Short Term ☒ Permanent ☐ Not Provided Schematics ☒ Short Term ☐ Not Provided Test Setup Photos ☒ Short Term ☐ Permanent ☐ Not Provided User’s Manual The above-mentioned company 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. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality (if applicable): The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public before the requested period has expired. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04- 1705.
