Indicator inspection

1. Plug the Ranger pressure infusor into an appropriate outlet. 2. Turn the main power switch located underneath the pressure infusor ON. Verify all the Ranger pressure infusor status indicators and power button indicators illuminate for approximately two seconds (see Figure 1). 3. Repeat as necessary to verify the indicators.

Testing the pressure infusors

Tools and equipment • •

mmHg pressure gauge Saline/fluid bag (6” x 10” [152.4 x 254 mm]), 1000 mL, unpurged

Method 1. Insert the saline bag into an infusor. Note: For the following instructions, observed output pressure of the Ranger pressure infusor is dependent on surface area and volume of the fluid bag. To verify the output pressure, use an independent, calibrated pressure gauge and a new, unpurged 1000 mL (6” x 10” [152.4 x 254 mm]) fluid bag. 2. Prime the entire fluid outlet tube and attach to an independent calibrated pressure gauge. The inlet of the calibrated pressure gauge should sit at the same height as the fluid output (see Figure 2).

Figure 2: Pressure gauge 3. Zero the pressure gauge and confirm the unit of measure on the pressure gauge is “mmHg”. 4. Turn ON the pressure infusor by pressing the pressure infusor power button on the pressure infusor control panel. 5. Wait three minutes for pressure infusor to stabilize pressure. 6. Verify calibrated pressure gauge reading is within 250-340 mmHg with no flow. Note: The reading on the calibrated pressure gauge will vary with the surface area and volume of the fluid bag. 7. If the pressure infusor is outside of the calibration range please call 3M Customer Service at 1-800-228-3957. 8. Turn OFF the pressure infusor. 9. Repeat in second chamber if calibration is within specification.

Portable and mobile RF communications equipment should be used no closer to any part of the model 145, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. Recommended separation distance d = 1.2√P d = 1.2√P 80 MHz to 800 MHz d = 2.3√P 800 MHz to 2,5 GHz where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the compliance level in each frequency range. b Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the model 145 is used exceeds the applicable RF compliance level above, the model 145 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the model 145. b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. a

Recommended separation distances between portable and mobile RF communications equipment and the model 145. The model 145 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the model 145 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the model 145 as recommended below, according to the maximum output power of the communications equipment.
