DESCRIPTION Discus Dental 04-1293P03 Transmitter Module is a radio frequency transmitting device intended for integration into professional products requiring a wireless link. This module does not contain the receiver necessary to complete the wireless link. The module also includes a Hall sensor which measures magnetic fields. This feature allows the use of low cost permanent magnets for measuring small change in distance, such as the ones used in foot pedal or foot switch applications. Magnetic field strength data is sent through the wireless link to the receiver. II. MODULE SPECIFICATIONS AND REQUIREMENTS a.

RF Communications Specifications The module transmits within the 2.4GZ ISM band. The selected frequencies of operation are: Channel # Frequency [MHZ] 1 2405 2 2410 3 2415 4 2420 5 2425 6 2430 7 2435 8 2440 9 2445 10 2450 11 2455 12 2460 13 2465 14 2470 15 2475 Sync 2478 There are 15 channels of normal operation and one specially assigned channel, sync, only used for transmitter-receiver pairing purposes. During the pairing (synchronization) process, both a new channel number and a new 5- byte address are selected by the module and get communicated to the receiver. Each time it is paired with a receiver, the module increases the frequency by 2 channels, meaning 10MHZ increments. The change is always in the ascending order and wraps around once the maximum normal operating channel number (channel 15) has been exceeded. For example, if starting at channel 1, then the following are the order of channel numbers every time pairing is performed: 1, 3, 5, 7, 9, 11, 13, 15, 2, 4, 6, 8, 10, 12, 14, 1, 3, ...... 8550 Higuera Street Culver City, CA 90232 (310) 845-8200 phone (310) 845 1500 fax discusdental.com f. Indicators: There are 3 indicators on the module: 1. Amber: This light blinks when power supply voltage level drops below approximately 3.4V. Though the module is still functional at this point, it acts as a warning for the User to replace the batteries soon (if batteries are used as the source of power). 2. Green: This light indicates the unit is in fully powered and awake, but in idle mode. It is ready to transmit if the magnetic field is strong enough to qualify. 3. Blue: The blue light, when solid on, indicates normal RF packets are being transmitted. When blinking, it indicates that it is in pairing (Sync) mode. III. OPERATING INSTRUCTIONS a. Pairing With a Receiver: i. The receiver (not supplied with this module) must be put into learning mode in order to start the pairing process ii. Then, the button on this module must be pressed continuously until the blue light starts flashing. This usually takes about 3 seconds. iii. Once blue light starts flashing, release the button and the module will start a pairing mode transmission lasting about 10 seconds. The pairing mode packets contain the new wireless address and channel for the receiver to learn. b. Sleep and Wakeups: The module enters a low power sleep mode as soon as power is applied to it. The green and blue lights are off in this state. The amber light may blink if the supply voltage is low. A magnetic force applied to the Hall sensor at the center of the board wakes up the module, and RF transmission begins. A solid blue light indicates this event. c. Transmitting and Idle Modes: While transmitting, the blue LED will remain on. Once the magnetic force is no longer applied, the module enters idle mode and remains in that state for up to 2 minutes. The green light will be on during this time. If no magnetic force is sensed in this period, the module will enter low power/sleep mode and the green and blue lights will remain off. 8550 Higuera Street Culver City, CA 90232 (310) 845-8200 phone (310) 845 1500 fax discusdental.com d. Calibration: Due to variations in magnetic forces and the mechanical distance of it to the Hall sensor, calibration may be necessary in order to provide the largest possible dynamic range. The magnetic force has to be in the acceptable range in order for calibration to be possible. Calibration is intended for final product factory use, though calibrating in field is not prevented. Here are the inst…

8550 Higuera Street Culver City, CA 90232 (310) 845-8200 phone (310) 845 1500 fax discusdental.com Feb 23, 2010 Timco Engineering 849 N.W. State Road 45 PO Box 370 Newberry, FL 32669 Attn: Director of Certification FCC ID: VIK-OH001 Request Limited Modular Authority We hereby request Limited Modular Approval based on the numbered requirements identified below as we address them to be included in our application for equipment authorization. 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. Our equipment meets this by having a ground plane and a power plane within its PCB layers underneath the RF components and not requiring further shielding due to meeting radiated emission levels of 15.249 and 15.209. Discus Dental maintains full control of the end product into which the module will be installed. The Module will always be contained in variations of same or similar mechanical structures that will not have any other circuitry, ever. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. Our equipment meets this by having a complete, self-contained design where there are no electrical inputs (other than power) to accommodate external devices. The only input is a magnetic one and gets sensed via the module’s Hall sensor chip. Data rates and modulations are all built in and fixed, and not dependent on the magnetic field strength. 3. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. Our equipment meets this by having on-board 3V regulator, which further gets regulated internally by the Nordic nRF24LE1 radio chip. Therefore, power supply voltage variations do not affect transmission power levels or modulation levels. 8550 Higuera Street Culver City, CA 90232 (310) 845-8200 phone (310) 845 1500 fax discusdental.com 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Any antenna used with the module must be approved with the module, either at the time of initial authorization or through a Class II permissive change. The “professional installation” provision of Section 15.203 may not be applied to modules. Our equipment meets this by having a fixed PCB trace antenna. Antenna is not detachable and is part of the module. The module is a single-board design. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). Our equipment meets this when testing the module by itself. The module is a battery operated device and has battery terminals build into it. No housings are used during testing. 6. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. Our equipment meets this by showing the FCC ID number on the module label. The User’s Manual and Installation Guide directs the User to also have this FCC ID on the outside of the final product, especially since the module will not normally be visible when installed. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be 8550 Higuera Street Culver City, CA 90232 (310) 845-8200 phone (310) 845 1500 fax discusdental.com Brian Zargari Device Development Department included in the application for equipment authorization.
