Taking Your Blood Pressure To begin, sit down, put on the blood pressure cuff, and press the START/STOPbutton. Your blood pressure (BP) is measured and displayed automatically. 1. Sit comfortably with your left forearm resting on a flat surface so that the center of your upper arm is at about the same height as your heart. 2. Loosen the blood pressure cuff so that you can slide the cuff over your arm. Place your hand into the cuff. 3. Slide the cuff up your forearm. 4. As you slide the cuff on, position the cuff so that the bottom of the cuff is on your upper arm and about one inch above the elbow crease; make sure that the air hose dangles on the inside of your arm. 5. Pull on the cuff end to tighten it. The cuff does not have to be pulled very tight. For comfort, you can leave room for one fin- ger to fit under the cuff. 6. Fold the cuff end back over the metal D-ring, and fasten the cuff end to the Velcro ® closure. 7. Press the START/STOPbutton. Sit still and do not move your arm during the measurement. If you want to stop the measure- ment at any time, press the START/STOP button. Wait 15 min- utes before taking your blood pressure again. M3815-90001-UG-Eng-revD.qxd 5/1/01 4:20 PM Page 2 3 BP User Guide 8. A series of numbers and symbols appear in the display window. The cuff inflates and may feel tight. A long beep signals the end of the BP measurement and the cuff deflates. The display window shows your final BP measurement and pulse rate. WARNING:As you watch the display, if you notice the pressure increase above 330 mmHg OR if the pressure decreases and remains at 15 mmHg for more than 3 minutes, press the START/STOPbut- ton to stop the measurement. The BP Unit is defective. Contact your Health Care Provider. 9. You can remove the cuff. The BP Unit has taken your blood pres- sure and pulse rate. The BP Unit turns off automatically. Note:Do not store the BP Unit with the air hose twisted or wrapped tightly around the display.

Description of the Philips Home Blood Pressure Transmitter circuit Robert C. Leichner 6 September 2001 The M3815 Blood Pressure transmitter circuit is based on R. F. Monolithics (RFM) TR1000 hybrid transceiver module. Printed circuit board load options have been selected to constrain the transceiver to three operating modes. The operating mode in effect at any given time is selected by the device microprocessor. The available modes are Standby, Transmit, and Test. • Standby mode is a very low power consumption state in which the transceiver consumes absolute minimum power, and emits no RF energy. • Transmit mode is constrained, again by load options, to ON-OFF keying. Transmit mode is the normal mode for transfer of measurement and status messages. Transmit mode is used during FCC part 15 testing. • Test mode is identical to Transmit mode except that RF output is reduced by approximately 3 dB. Test mode – rarely used - is used during device installation, and to verify RF link operation. Characteristics of the 19.6kilobit serial data stream that modulates the TR1000 output in Transmit and Test modes are presented elsewhere in the FCC 15.249 submission. Quoting from the RFM TR1000 data sheet: TR1000 916.50 MHz Hybrid Transceiver The TR1000 hybrid transceiver is ideal for short-range wireless data applications where robust operation, small size, low power consumption and low cost are required. The TR1000 employs RFM’s amplifier-sequenced hybrid (ASH) architecture to achieve this unique blend of character-istics. All critical RF functions are contained in the hybrid, simplifying and speeding design-in. The receiver section of the TR1000 is sensitive and stable. A wide dynamic range log detector, in combination with digital AGC and a compound data slicer, provide robust performance in the presence of on-channel interference or noise. Two stages of SAW filtering provide excellent receiver out-of-band rejection. The transmitter includes provisions for both on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The transmitter employs SAW filtering to suppress output harmonics, facilitating compliance with FCC 15.249 and similar regulations. The TR1000 transmitter output power is determined by current flowing into TXMOD (pin 8 of the TR1000). The transmitter design supports both Transmit mode used to transfer Blood Pressure measurement results and status messages, as well as a reduced power test mode. R74 and R75 control the current into TR1000 pin 8 in the higher power normal mode. The two resistors are used in series to allow the combined resistance, and the resulting power level, to be set with greater precision than possible using a single standard resistor value. The data signal driving the resistors and the TR1000 TXMOD input is the output of a 74HC00 quad NAND gate. The 74HC00 output is lightly loaded by the transmitter, and when driven, will be stable and close to the power supply voltage. The power supply voltage is controlled by a linear regulator (Micrel MIC5219-3.0BM5) with better than 1% output load regulation and worst case accuracy of 2%. In combination, these factors result in a well-controlled drive signal to the RFM TR1000. R76 modifies the drive to the TXMOD pin by diverting a portion of the available drive current when RFattenuate- is asserted (LOW). Current into TXMOD, and the resulting TR1000 output level, are reduced when Rfattenuate- is asserted. R76 was selected to produce a 3dB drop in RF output level. D4 is reverse biased during Transmit mode assuring that R76 is isolated from the transmitter during non-test operation.

The testing was performed at an antenna to EUT distance of 3 or 10 meters below 1 GHz, and at a distance of 3 or 1 meter(s) above 1 GHz. The actual test distance used is noted in the test data sheets. The device’s performance was investigated to 10GHz. The EUT was powered by four Duracell PC1500 PROCELL 1.5Volt AA batteries. Fresh batteries were used for all testing. The circuit board was hardwired so as to produce a continuous transmission signal as opposed to the momentary transmission that occurs during regular operation. Since the device is a table- top unit, the emissions were maximized around the vertical axis and the maximum reading was recorded. The integrated antenna cannot be maximized separately. All other performance tests were made in accordance with the procedures outlined in Part 15 of CFR 47. The applicable sections provided under Part 15 are provided in the measurement section of this report.
