MULTIBAND P25 AIRBORNE TRANSCEIVER MODEL TDFM-600/6000 Installation and Operating Instructions Til Document No. 01RE293 Rev. C Issue 6 May 2004 Technisonic Industries Limited 240 Traders Blvd, Mississauga, Ontario L4Z 1W7 Tel:(905)890-2113 Fax:(905)890-5338 www.til.ca CAUTION This unit contains static sensitive devices. Wear a grounded wrist strap and/or conductive gloves when handling printed circuit boards. WARNING: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE : This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Warning: Changes or modifications not expressly approved by Technisonic Industries could void the users authority to operate the equipment. WARRANTY INFORMATION The Model TDFM-600/6000 Transceiver is under warranty for one year from date of purchase. Failed units caused by defective parts, or workmanship should be returned to: Technisonic Industries Limited Technisonic Industries Limited 240 Traders Boulevard 3840 E.

The transmitter antenna gain shall not exceed 3 dBi 2. The transmitter antenna is required to be located outside of a vehicle and kept at a separation distance of 70 cm or more between the transmitter antenna of this device and persons during operation. Summary of DO-160C Environmental Testing for Technisonic Model TDFM-600 and 6000 Transceiver. Conditions Section Description of Conducted Tests Temperature and Altitude 4.0 Equipment tested to categories C4 and D1. Vibration 8.0 Equipment is tested without shock mounts to categories B, M and N. Magnetic Effect 15.0 Equipment is class Z. Power Input 16.0 Equipment tested to category B. Voltage Spike 17.0 Equipment tested to category B. RF Emission 21.0 Equipment tested to category Z. Installation Approval Note Presently no TSO standard exists for airborne FM transceivers. To make it easier for installation agencies to provide their customers with an approved installation supported by an effective Airworthiness Approval, Technisonic has secured Supplemental Type Certificate (STC) Approvals (both US and Canadian) on its Airborne FM products for many helicopters currently being delivered in the US and Canada as well as a number of single engine fixed wing aircraft. The above referenced DO-160C test data is also on file and available from Technisonic to support approval requirements in airframes for which Technisonic does not possess an STC. Approved aircraft types are listed in the attachments to the formal STC documents. These STC's are the exclusive property of Technisonic and require the written authority of Technisonic for their use. To assist Factory Authorized Technisonic Dealers in the certification process, we have placed copies of our Canadian and US STC's on our web site along with a letter of authorization for their use. These documents may be downloaded and used as support for the technical submission to FAA or Transport Canada. Only factory authorized dealers/installers are permitted to download and make use of these documents on behalf of their customers (end users) in support of regulatory agency approval. Please refer to the Technisonic web site www.til.ca for the latest issue of available STC=s and letter of authorization for use.
