To installthe battery, unscrew the battery cap using a coin (Figure 2a). Noting the battery polarity, install a new cell, positive ”+” end in first (Figure 2b). Screw battery cap securely into place. When a new battery is first installed, the In-Mask Receiver will blink the green low-battery indicator for 5 seconds to indicate that the battery has been installed correctly. Caution:The cell used in this device may present a fire or chemical burn hazard if mistreated. DO NOT recharge, disassemble, heat above 100 o C, or incinerate. Dispose of used cell promptly. Keep away from children. Transducer The Transducer is powered by two (2) CR2 lithium batteries. To install the batteries, unscrew the battery cap using a coin (Figure 3a).Noting the battery polarity, install twonew cells, positive ”+” end in first (Figure 3b). Both batteries MUSTbe replaced with fresh cells at the same time. Screw battery cap securely into place. Caution:The cell used in this device may present a fire or chemical burn hazard if mistreated. DO NOT recharge, disassemble, heat above 100 o C, or incinerate. Dispose of used cell promptly. Keep away from children. Note: Install batteries with transducer in transmission range of In-Mask Receiver. When new batteries are first installed, the In-Mask Receiver will blink the amber low-battery indicator for up to 5 seconds to indicate that the batteries have been installed correctly. Note: Use only Duracell or Energizer CR2 lithium batteries.

Refer to the mask cleaning procedure in the Draeger Service manual. Transducer: Use a damp cloth to clean the surface of assembly. Wireless HUD System Operation The In-Mask Receiver is located inside the mask. It will power-up when it is in range of a transducer unit that is sensing air pressure. The transducer is located on the back plate and is connected to the high pressure line (Figure 4). When the In-Mask Receiver receives the first air pressure signal from the transducer, the display will initially be on for 20 seconds. After that the display will function as described below. You should be at least 6 Feet away from another PRISM system when first pressurizing your SCBA to prevent your In-Mask Receiver from linking to another system. If this occurs, move away from the other individual. Your In-Mask Receiver will display a Loss Of Signal indication in approximately 40 seconds then link to your own SCBA. A properly linked PRISM system will function correctly when usedin close proximity to another properly linked system. In-Mask Receiverlow-battery indicator The Green led will flash at a rate of approximately once per second. Transducer low-battery indicator The Amber led will flash at a rate of approximately once per second. Tank Pressure below ¼ The Red led will blink at a rate of once per second until the tank is out of air. Tank Pressure between ¾ & ½ 3 leds (R,A,G) will be on for 12 seconds and then be off for 48 seconds. Tank pressure between ½ and ¼ The Red led will be on for 24 seconds, while the Amber led will blink at a rate of once per second for 24 seconds. Both leds will then be off for 36 seconds. After that, both leds will be on for 12 seconds and then be off for 48 seconds. Tank Pressure above ¾ All 4 leds (R,A,G,G) will be on for 12 seconds and then be off for 48 seconds.

Statement of Compliance: I hereby certify that the measurements of radio frequency emissions from the Audiopack HUD transmitter were performed by me between December 10 and 12, 2002, and that the results of the measurements confirmed that the prototype unit tested is capable of compliance with the above regulations for an intentional radiator and for a Class A digital device. December 20, 2002 __________________ Date President James R. Pollock 3 INTRODUCTION: The device tested is designed to be connected in line with an emergency worker’s air or oxygen supply line and to transmit rough air pressure values to a companion receiver located in the individuals field of view where colored lights indicate air status. The battery operated transmitter’s frequency of operation is 37.0 kHz and a ferrite core loop antenna is totally contained within the housing and is not accessible to the user. The ±1.8 kHz FSK modulation produces a dual peak on the spectrum analyzer at 37 ±1.8 kHz as the fundamental frequency. The transmitter has no operator controls but does contain a microprocessor running at 4 MHz. EMISSIONS MEASUREMENTS: The emissions from the transmitter portion of the device were investigated from the lowest frequency of operation (35.2 kHz), to 30 MHz (¶15.33). The emissions from the digital device portion of the device were examined from 30 MHz – 1000 MHz. As the device is battery powered, no conducted emissions measurements were performed. RADIATED EMISSIONS, TRANSMITTER: The emissions from the transmitter were first examined in the shielded room using a shielded loop antenna at close range. Using the information from this test, the test equipment was moved to an open area in which measurements could be made with little or no effect from reflecting objects. Even at a distance of 2 m, only the first frequency pair could be detected. Measured values of these two frequencies were made using the loop antenna, rotating the transmitter to maximize the measured value and also orienting the transmitter along each of three orthogonal axes. The maximum values obtained using a 3 kHz bandwidth were recorded. The peak values of these emissions, along with appropriate correction factors are shown in Table 1 below. 4 Table 1 Transmitter Fundamental Freq. (MHz) Value (dBuV) @2 m Ant.

(Inverse distance squared) 1 meter measurements converted to 300 m by subtracting 99 dB. (Inverse distance squared) 1 meter measurements converted to 30 m by subtracting 59 dB. (Inverse distance squared) Reading at 2250 kHz has 26 dB amplifier gain subtracted to arrive at 8 dB. * Inverse distance squared from 2m to 300m is an 87 dB reduction. As none of the harmonics were measurable at the two meter distance, the information obtained in the shielded room at a distance of about 1 meter was used to show that all the harmonics are lower in magnitude than the fundamental. This information is seen in Figs. 1 & 2. In both figures, the red trace is the ambient level and the black trace is the measured level. The bandwidth is set so that the peak level of the transmission is recorded. 5 Figure 1 covers the range between 30 kHz and 500 kHz, while Fig. 2 covers from 500 kHz to 30 MHz. The calculated limit adjusted to 1 meter is also shown on each plot. As can be seen from the table and the plots, all peak emissions from the transmitter are more than 30 dB below the limits of 15.209. RADIATED EMISSIONS, DIGITAL DEVICE: As the transmitter does contain a microprocessor, it qualifies as a Class A digital device. The emissions of this part of the system were first examined in the shielded room where the lower ambient level makes determining the presence of emissions easier. These emissions were measured at a distance of one-meter using linearly polarized antennas in both horizontal and vertical modes. Figures 3 & 4 show the data obtained and a comparison to the Class A limit. At approximately 48 MHz, the indicated emission is about 20 dB below the Class A limit. Experience with in-room measurements indicates that readings in this area of the spectrum typically read significantly higher in the room than on the open area test site (OATS). This was borne out again as the transmitte…
