Page 1 of 4 Rev. 1.01 5/21/99 wc Operating manual for Wireless Cuff .doc Operation manual for the 1023018 wireless transmitter Wireless Cuff Preparation: The wireless cuff includes five components, a battery assembly (hub), “O” ring, transmitter assembly, a bracelet and four screws. (See figure 1) • Battery Assembly - Provides a nominal 6 Volt DC source to power the transmitter when assembled. Life is estimated at 3 months average. The transmitter will cease operation at around 3.9 Volts. • “O” Ring - Seals the transmitter compartment when assembled making it waterproof. • Transmitter Assembly - Encapsulated transmitter with battery contacts for power. Periodically sends a message to the receiver which is resident in the PTU. • Screws, 4 each - #4 Phillips, flat head, stainless steel, sheet metal screws; 3/8” in length. A cuff may be attached to a client once preparation has been completed. Select an appropriate length bracelet for the ankle (table 1), one battery assembly with “O” ring installed, one transmitter assembly and four screws. Sizes 5,6,7 and 8 are stocked by ABS. Other sizes will have to be special ordered at the time of contract. Lead time is two weeks. # of holes Ankle Circumference # of Holes Ankle Circumference 2 6.5” 7 9.0” 3 7.0” 8 9.5” 4 7.5” 9 10.0” 5 8.0” 10 10.5” 6 8.5” 11 11.0” Table 1 Assemble Transmitter and Battery: Align the battery assembly key appropriately with the transmitter assembly slot and lightly engage the hub of the battery assembly to the transmitter cavity. Rotate one assembly carefully until the index mark on one aligns with the index mark on the other. Press the two assemblies together firmly with both hands until little gap can be observed between the two assemblies. Hold them in place with one hand and insert one screw (using a Phillips screwdriver) at a time. Insert the second screw 180 degrees from the first and tighten. The other two screws may be inserted in any order. Wireless Bracelet Installation: Figure 2 provides the necessary client installation instructions. Install the bracelet to one side of the cuff assembly first. The second side is installed while against the clients wrist or ankle. Once the cuff is installed on the client it must be activated. Activation occurs when the magnet provided is placed against the transmitter body for a minimum of five seconds. Once activated the client is free to move within the limits of the following violation definitions. Page 2 of 4 Rev. 1.01 5/21/99 wc Operating manual for Wireless Cuff .doc • Proximity - Occurs when the client, wearing the cuff, moves away from the PTU between 20 ft. outdoors or 30 ft indoors. To be detected as a cuff violation the client must outside these limits for a minimum of for 30 minutes. This violation rearms itself if an individual moves back inside these limits after being out for 30 minutes. • Cuff violation - Occurs when a client forcibly removes or cuts the bracelet from the transmitter. This violation will not page again until the bracelet has been replaced and the cuff has been rearmed (minimum of 10 seconds) with the rearming tool. Cautions • After rearming is complete the client must stay within the proximity limits for 5 minutes. Premature movement outside these limits may prevent a cuff violation from being detected. • Metal obstructions, in the line of sight between the cuff and the PTU, such as metal filing cabinets, walls or refrigerators can result in false proximity violations.

There are no other simultaneous applications . 1.2 Product Description The wireless cuff includes five components, a battery assembly (hub), “O” ring, transmitter assembly, a bracket and four screws. Battery Assembly-Provides a nominal 6VDC source to power the transmitter when assembled. The transmitter will cease operation at around 3.9VDC. “O” Ring – Seals the transmitter compartment when assembled making it waterproof. Transmitter assembly – Encapsulated transmitter with battery contacts for power. Periodically sends a message to the receiver which resident in the PTU. 1.3Test Methodology Radiated emission measurements were performed according to the procedures in ANSI C63.4 (1992). All measurements were performed in Open Area Test Sites. Preliminary scans were performed in the Open Area Test Sites only to determine worst case modes. For each scan, the procedure for maximizing emissions in Appendices D and E were followed. All Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the "Justification Section" of this Application. 1.4Test Facility The test site facility used to collect the radiated and conducted measurement data is located at 7435 4th Street North, Oakdale, Minnesota. This test facility has been fully described in a report dated on September 1996 submitted to your office. Please reference the site filing number: 31040/SIT 1300F2, dated December 26, 1996.

The EUT was set up as tabletop equipment. 2.2 EUT Exercising Software The ABS Cuff transmitter was tested in the continuous transmission mode. 2.3Special Accessories There are no special accessories necessary for compliance of these products. 2.4 Equipment Modification No modifications were installed during the testing. 2.5Support Equipment List and Description N/A 2.6Test Configuration Block Diagram (see Exhibit I) A FCC ID: OAM 1023018 Report No:J99011549 - May,1999 Page 3 of 12 3.0EMISSION RESULTS Data is included of the worst case configuration (the configuration which resulted in the highest emission levels). A sample calculation, configuration photographs, data tables and graphical representations of the emissions are included. 3.1Field Strength Calculation The field strength is calculated by adding the Peak reading on the EMI Receiver to the factors associated with preamplifiers (if any), antennas and cables. A sample calculation is included below. FS = RA + AF + CF - AV Where FS = Field Strength in dBV/m RA = Receiver Amplitude (including preamplifier) in dBV CF = Cable Attenuation Factor in dB AF = Antenna Factor in dB AV = Average Factor Assume a receiver reading of 47 dBV is obtained. The antenna factor of 19.5 dB and cable factor of 3.5 dB is added. The net field strength for comparison to the appropriate emission limit is 67 dBV/m. The average factor of 20dB is subtracted from the readings. A FCC ID: OAM 1023018 Report No:J99011549 - May,1999 Page 4 of 1…

Duty cycle factor calculations The pulse train is less than 100 ms including blank intervals. The duty cycle calculated by averaging the sum of the pulse widths over one complete pulse train. The sum of the pulse widths is 0.32ms x 30 pulses in the train = 9.6 ms The length of the period is 108 ms The duty cycle is 9.6 ms/108 ms = 0.089 The Peak-Average correction factor derived from the duty cycle 20lg(0.089)=-21dB The maximum Peak-Average correction factor is 20dB Please see the attached graphs for the pulse train measurements.
