The helmet is made to absorb the energy of a blow by partial destruction or damage to the shell and the harness, and even though such damage may not be readily apparent, any helmet subjected to severe impact should be replaced. The attention of users is also drawn to the danger of modifying or removing any of the original component parts of the helmet, other than as recommended by the helmet manufacturer. Helmets should not be adapted for the purpose of fitting attachments in any way not recommended by the helmet manufacturer. Do not apply paint, solvents, adhesives or self-adhesive labels, except in accordance with instructions from the helmet manufacturer. This hardhat is designed to provide limited head protection from small falling objects striking the top of the hard hat. It is not designed to provide front, side or rear impact or penetration protection. Avoid contact of this hard hat with electrical wires. Use only with Guardhat designated suspension system. Inspect all parts of your hard hat regularly. Immediately replace at the first sign of cracking, frayed straps or any wear, damage, abuse, impact or plastic degradation as this may be an indication the protection is reduced. Prolonged exposure to sunlight could degrade the shell. Do not store in direct sunlight when not in use. Clean with mild soap and water. This hat is not reversible. The hard hat should be replaced within 5 years of the stamped manufacturing date, regardless of outside appearance. If the product is used under extreme conditions, such as exposure to high temperatures, chemicals, or sunlight, hard hats should be replaced after two years of use. The hard hat date of manufacture can be found in the rear of the white shell, next to the battery compartment. It is recommended to replace the entire suspension system at least every 12 months. The helmet must be delivered in packaging supplied by the manufacturer. Guardhat IS-HC1.1 User Manual 12 This device is to be used only as intended. The stated purposes are to act as a hard hat, provide location services, and communicate events. Use outside of this scope constitutes inappropriate usage, will void the warranty, and may cause safety hazards to personnel. The hat is certified IP65 with the battery pack properly installed. The battery terminals on the hat and the battery pack are not protected from dust and moisture when the battery pack is not installed. Hence, prior to installing a battery pack, both the hardhat battery terminals and the battery pack terminals must be inspected and cleaned to ensure no accumulation of debris or moisture. The IS-HC1.1 and battery packs should not be disassembled at any time. Doing so will void the warranty and may cause harm to the user. The hat or battery pack should not be used thereafter. If a hat or battery under warranty becomes damaged, cease use and contact Guardhat immediately. Only dispose of a battery (damaged or otherwise) at a properly rated hazardous waste or recycling location. EX Safety If there is any reason to suspect that the safety of the device has been compromised, it must be withdrawn from use and removed from any ex-hazardous areas immediately. Measures must be taken to prevent any accidental restarting of the device. The safety of the device may be compromised, if, for example:

malfunctions occur. the housing of the device shows damage. the device has been exposed to excessive loads. the device has been stored improperly. markings or labels on the device are illegible. We recommend that a device displaying errors or which an error is suspected be sent back to i.safe MOBILE GmbH to be checked. Guardhat IS-HC1.1 User Manual 13 Use of this device assumes that the operator observes the conventional safety regulations and has read and understood manual, safety instructions and certificate. When used in ex-hazardous areas, the following safety regulations must also be complied with:

The device may not be exposed to any aggressive acids or alkalis. The battery shall be charged outside the explosion hazardous areas only and using an approved charging adapter The battery may only be charged at temperatures between 5C ... 35C. The device must be protected from impacts with high impact energy and high electrostatic processes. Only accessories approved by i.safe MOBILE GmbH may be used. The device may only be used in zones 1, 2, 21, or 22. Battery Fit CAUTION RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS. This device contains a Lithium-Ion (Li-ion) Rechargeable Battery. This battery may be forbidden aboard passenger aircraft and is not to be transported via air with a charge greater than 30%

capacity per ICAO Packing Instructions 965. Damage to a Li-ion battery may result in a flammability hazard. Only batteries manufactured by Guardhat are safe to use with this model. Only a Guardhat charger should be used to charge the batteries. Charging must take place only in an environmentally safe location because any intrinsic safety or ingress protection ratings held by the hard hat assembly are not applicable to a battery with exposed terminals. The hat must be worn snugly to prevent slipping off. Always adjust the suspension to fit the user before wearing into a work zone.

Put the hard hat on your head and tighten the suspension as necessary by turning the knob clockwise. Figure 3: Suspension Adjustment There are five aspects to the hats user interface. Buttons are pressed by the user in order to communicate, both with the Safety Control Center

(SCC) and with other users. LEDs indicate to the user when there is an event or pending communication. The speakers play standard and custom messages to be heard by the user. They also enable two-way communication with the SCC and/or other users. Guardhat IS-HC1.1 User Manual 16 The microphone allows the user to communicate directly with the SCC and/or other users as well as to capture audio to accompany a video recording. The camera is capable of capturing both still images and video, which are transmitted to the SCC. It also allows for video calling to show the Safety Operator what the user sees in real time.

Guardhat IS-HC1.1 User Manual 18 LED Indicators There are 5 LEDs on the underside of the brim, visible to the user (see Figure 6) and two LEDs on the outside of the hat, visible to nearby personnel (see Figure 7). The LEDs light up with various colors and frequencies depending on the event / message (see TABLE for a full list of LED indicators and the associated events). The visual indicator of the LEDs is a key communication method that responds to events triggered by the user, by the SCC, and by the hat / the software that powers it. These lights alert users even in situations where ambient noise is too high to accurately hear audio communication. Figure 6: LED Indicators (Under the Brim) Guardhat IS-HC1.1 User Manual 19 Figure 7: Neighbor LEDs Communication: Microphone, Speakers, & Camera The speakers allow communication to be extremely specific. While the same color might light up for multiple events, each audio alert is unique and can provide detailed notifications. Additionally, the SCC can communicate to users via the speakers and users can communicate with each-other using Push-to-Talk for CB-Style communication. There are two speakers, one located on each side of the hard hat brim, and two microphones;

one under the brim and one next to the camera (see Figure 8 & Figure 9). The speaker volume can be adjusted up or down by pressing the or button as shown in Figure 8.

The stated purposes are to act as a hard hat, provide location services, and communicate events. Use outside of this scope constitutes inappropriate usage, will void the warranty, and may cause safety hazards to personnel. The hat is certified IP65 with the battery pack properly installed. The battery terminals on the hat and the battery pack are not protected from dust and moisture when the battery pack is not installed. Hence, prior to installing a battery pack, both the hardhat battery terminals and the battery pack terminals must be inspected and cleaned to ensure no accumulation of debris or moisture. thereafter. immediately recycling location. The HC-1 and battery packs should not be disassembled at any time. Doing so will void the warranty and may cause harm to the user. The HC-1 or battery pack should not be used If an HC-1 or battery under warranty becomes damaged, cease use and contact Guardhat Only dispose of a battery (damaged or otherwise) at a properly rated hazardous waste or To prevent possible hearing damage, do not listen at high volume levels for long periods. IEC 60417-6044 Guardhat HC-1 User Manual 10 Battery CAUTION RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS. This device contains a Lithium-Ion (Li-ion) Rechargeable Battery. This battery may be forbidden aboard passenger aircraft and is not to be transported via air with a charge greater than 30%

capacity per ICAO Packing Instructions 965. Damage to a Li-ion battery may result in a flammability hazard. Only batteries manufactured by Guardhat are safe to use with this model. Only a Guardhat charger should be used to charge the batteries. Charging must take place only in an environmentally safe location because any intrinsic safety or ingress protection ratings held by the hard hat assembly are not applicable to a battery with exposed terminals. The hat must be worn snugly to prevent slipping off. Always adjust the suspension to fit the user before wearing into a work zone.

Put the hard hat on your head and tighten the suspension as necessary by turning the knob clockwise. Figure 3: Suspension Adjustment There are five aspects to the hats user interface. Buttons are pressed by the user in order to communicate, both with the Safety Control Center

(SCC) and with other users. LEDs indicate to the user when there is an event or pending communication. The speakers play standard and custom messages to be heard by the user. They also enable two-way communication with the SCC and/or other users. Guardhat HC-1 User Manual 13 The microphone allows the user to communicate directly with the SCC and/or other users as well as to capture audio to accompany a video recording. The camera is capable of capturing both still images and video, which are transmitted to the SCC. It also allows for video calling to show the Safety Operator what the user sees in real time. Buttons Figure 4). There are 7 buttons on the underside of the brim (see Figure 5) and 1 button on the top (see Figure 4: Top Button Guardhat HC-1 User Manual 14 Figure 5: Brim Buttons Power Button.

Used to capture still images and video recordings which are transmitted to the SCC. LED Indicators There are 5 LEDs on the underside of the brim, visible to the user (see Figure 6) and two LEDs on the outside of the hat, visible to nearby personnel (see Figure 7). Guardhat HC-1 User Manual 15 The LEDs light up with various colors and frequencies depending on the event / message (see TABLE for a full list of LED indicators and the associated events). The visual indicator of the LEDs is a key communication method that responds to events triggered by the user, by the SCC, and by the hat / the software that powers it. These lights alert users even in situations where ambient noise is too high to accurately hear audio communication. Figure 6: LED Indicators (Under the Brim) Guardhat HC-1 User Manual 16 Figure 7: Neighbor LEDs Communication: Microphone, Speakers, & Camera The speakers allow communication to be extremely specific. While the same color might light up for multiple events, each audio alert is unique and can provide detailed notifications. Additionally, the SCC can communicate to users via the speakers and users can communicate with each-other using Push-to-Talk for CB-Style communication. There are two speakers, one located on each side of the hard hat brim, and two microphones;

one under the brim and one next to the camera (see Figure 8 & Figure 9). The speaker volume can be adjusted up or down by pressing the or button as shown in Figure 8. Note that the volume cannot be completely muted. real time as determined by the SCC. Messages conveyed via the speakers may be standard (e.g. Hat not worn) or may be custom /

Guardhat HC-1 User Manual 17 Figure 8: Communication (Bottom View) Figure 9: Communication (Front View) Guardhat HC-1 User Manual 18 EVENTS Guardhat model HC-1 detects a number of safety-related conditions and communicates these conditions known as events to multiple recipients, including the SCC. Your company may choose to customize which events are detected as well as the priority ranking of each event. Event Audio is listed in English however, the audio can be configured to multiple languages depending upon the country and language of the users. The priority of each event is only relevant if multiple events happen simultaneously. When this is the case, the event with a higher priority will be indicated first. Additional events may be queued for subsequent communication once the high priority event is resolved. Critical is the highest priority, followed by non-critical and informational. Note that the Event & SOS LEDs are on the underside of the brim and are visible to the User wearing the hat (see Figure 6). The Neighbor LEDs are on the outside of the brim and are visible to nearby users (seeFigure 7). events which include LED alerts. The following events are described in the subsequent tables.

Introduction The FXR.08.52.0075X.A.dg is an NFC Ferrite antenna with 75mm twisted pair 28AWG cable and JST connector. It works with specific NFC chips which need to connect via JST ACH connector. NFC antennas can be applied in areas not traditionally available to other types of antennas. A common example is the ability to apply NFC antennas to batteries or other conductive surfaces. To enable this usage, however, a ferrite flux director layer is required. This ferrite layer acts to steer the magnetic flux away from the metal or other conductor, where it would otherwise result in loss or complete failure to communicate. Taoglas NFC antennas can therefore be customized with flux director layers to enable this flexibility in usage. The coil inductance noted below can help estimate a capacitance value for creating resonance at 13.56MHz. Typical applications

- Mobile devices

- Electronic wallets

- Health care ID scanners

- Payment readers

- Office ID

- Access control

Internet Of Things Customized antennas for specific applications, shape, and impedance match can also be provided for an NRE and subject to MOQ.

The FXR.08.52.0075X.A.dg antenna is connected to a NFC evaluation board and then placed on the fixed part of the fixture. Evaluation Board Test Fixture Passively Powered Tag Sample on thin plastic sheet Antenna Measuring Scale Measurement Arm RFID Reader Module The test sample is placed on a thin sheet of plastic connected to the movable part of the fixture. Then the distance is carefully adjusted until the reader can no longer read the sample, thus the maximum interrogation distance is displayed in the ruler. SPE-15-8-079/B/CM Page 4 of 10 3.2. RFID tags used for test A total of 8 RFID tags were used to measure the interrogation distances. The next picture shows type 1 and type 2 tags, respectively. Type 1 Type 2 Type 1 tag is based on ISO/IEC 14443A standard and has 512 bytes of memory. Type 2 tag is based on ISO/IEC 14443A standard and has 192 bytes of memory. The next picture shows the Tag-it HF-I RFID tags from Texas Instruments: RI-102-

112, RI-I11-112, RI-I03-112, RI-I16-112, button type, and RI-I17-112. The Tag-it HF-I Plus Transponder Inlay family of Texas Instruments RFID is based on the ISO/IEC 15693 standard for contactless integrated circuit cards (vicinity cards) and ISO/IEC 18000-3 standard for item management. SPE-15-8-079/B/CM Page 5 of 10 3.3. Matching The interrogation distances presented here were taken with the antenna connected directly to the evaluation boards with the default matching circuit. This is not necessarily the optimal matching circuit that could be designed for a particular antenna. We kept the default matching of each evaluation board to minimize the number of variables in testing and keep integration as simple as possible. As with any matching network the exact circuit and values for an optimal network depend on the combination of antenna, NFC circuit, any intervening transmission line and the environment presented to the antenna. These factors are specific to the particular end product. As a starting point, to achieve the read range results presented here, use the matching network detailed in the schematic of the evaluation board for your particular NFC chip and keep the antenna free of any obstruction. Once you can demonstrate successful reads you can then optimize performance as desired. If the matching network is required, you should implement the following topology:

The matching circuit should be designed to match the IC impedance to 100 and then connect the antenna through a 100 differential pair. SPE-15-8-079/B/CM Page 6 of 10 3.4. Test Results A total of 8 sample devices were used to measure the interrogation distances in two scenarios, over plastic and over metal, using the Texas Instruments TRF7970AEVM evaluation board. The results are:
