MiniTouch Control System User Instructions DK Technologies, Inc. 9 Regola Drive Irwin, PA 15642 (724) 744-0420 Introduction The Mini Touch Hand Control System is designed to allow activation of up to 12 vehicle functions traditionally found on the left side of the steering column. These include (but are not limited to) turn signals, windshield wiper and washer, and high beam controls. The system is designed to operate in parallel with the original factory installed controls. System Components The MiniTouch system consists of an radio transmitter that is mounted to a spinner knob on the steering wheel, and a RF receiver module mounted underneath the dash. Each component will be described below. Note: The system is active only when the ignition switch is in the ON position. Transmitter The transmitter is the user’s interface to the system. It consists of up to 6 dual position momentary toggle switches. The transmitter is powered a 3.6 V battery located in the compartment on the rear of the transmitter. The battery should last for a minimum of 1 year of normal use. Note: As a function is activated, the LED on the top of the transmitter will flash. If it does not flash or if the response of the system becomes erratic, replace the battery. To replace the battery, remove the back cover of the transmitter. Place a new 3.6 V lithium battery (type 2/3 A) in the holder. Be sure to place the “+” terminal of the battery to the the “+” terminal of the battery holder. AGENCY NOTICE Changes or modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment. RF Receiver Module The RF receiver module is the direct interface to the vehicle’s electronics. The receiver translates the data sent by the transmitter into signals to control vehicle functions. The signals control external relays. It is mounted underneath the dash and is connected into the existing vehicle wiring.

If made public, the information might be used to the disadvantage of the applicant in the market place. Thank you for your attention to this matter. Daniel J. Janicik President DK Technologies, Inc.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 May 23, 2002 RE: FCC ID: NN7MT2000T Attention: Brian Dettling I have a few comments on this Application. 1 The confidentiality letter has the wrong FCC ID number for this application. Please provide a revised Confidentiality Letter with the correct FCC ID number. 2 The Operational description of the devices states that the antenna is a “circuit board trace that is located around the edge of the board. It is approximately 4.277" long by 0.025" wide and is matched with an inductor and capacitor to provide maximum allowed power output.” However, the Internal Photos show no such trace, but does show a 433-SP2 Linx grounded line planar antenna. Please explain and/or correct the technical description. 3 In the report (page 10 sec 4.4) you state that for the occupied BW the output of the EUT was coupled to the input of the analyzer. Was this coupling done using a near field probe, direct connection or was it done at 3 meters using an antenna? The reason I ask is that the level is close to the calculated field strength levels only slightly higher. This may be coincidence, but a short explanation of the coupling mechanism will help clarify the similarities in levels. This does not affect the data, it is only for information purposes.

This may be coincidence, but a short explanation of the coupling mechanism will help clarify the similarities in levels. This does not affect the data, it is only for information purposes. Per Greg Snyder, WLL Chief EMC Engineer: The antenna was randomly placed at a distance closer than three meters to the test item. The actual distance was not documented, as the test was set up to record a bandwidth plot.
