Private Address Wireless Network Two Way Communications for Extreme Noise Environment MODEL 460C OPERATING MANUAL Thank you for buying this HCS transceiver. This instruction manual contains important safety and operating instruction. Please read it carefully before using the Headset. HEAD CONNECTION SYSTEMS LTd. 112 Soundview Drive, Port Washington NY, 11050 – 1750 Fax: (516) 944-7556 For Extreme Noise Environment HCS Head Connection Systems Ltd . 2 1. Model-460C was tested and approved according the FCC part 90 for Programmable UHF commercial licence - FCC ID: M5U-101-460C GENERAL DESCRIPTION Two-way Programmable radio headsets (earmuffs), up to 4 frequencies, UHF (450-470MHz) transceiver, Ni-HM rechargeable battery operated, built into a highly efficient hearing protection for secure voice communications in noisy environments. Built in connector for Sell- phone / music plug or frequencies program cable. FUNCTIONALITY Enables wireless communication between all headsets and with an optional base-station on common frequencies. The noise-suppressing microphone efficiently reduces background noise. The headset microphone and speakers are used simultaneously with a connected cellular phone. Transmission can be initiated by manually push-to-talk or hands free VOX system. APPLICATIONS The applications for PAWN are many; Shop floors, Power plants, Forestry, Construction sites, Quarries, Recreational areas and other noisy areas where secure communication over short distances are essential. The plug-in sell-phone enables clear communication with the outside world. OPERATING INSTRUCTIONS Simplified controls make PAWN Headsets easy to use. A four-position switch selects the operating mode, either VOX /PTT or PTT. Rotary switch controls On/Off/Volume. 2. PRODUCT LAYOUT 1. PTT - ”talk” button for manual transmission 2. Program /cell phone Plug-in. 3. 4-way switch-VOX/PTT setting with three alternatives for adjusting VOX circuit’s sensitivity, to ensure "Hands-Free" correct microphone activation in relation to external noise levels. The PTT position, is activated via the ”talk” button. 4. Volume On/Off control for adjusting the volume level in the headset. 5. Frequency setting, - Two -position pre-set channels. 6. Charging socket. 1 3 2 5 4 6 3 3. Transmitting and receiving: The headset is in receiving mode, when turned ON by the Volume/ On/Off switch. To transmit voice, make sure that the microphone is very close to your mouth (about ½ “) and the white dot on the microphone is against your mouth. Push the PTT button or adjust the VOX sensitivity and start talking. After releasing the PTT or when you stop talking in VOX mode, you and all other recipients will hear a beep tone- to confirm end of transmission. 4. Adjustment of the VOX sensitivity: A. Maximum sensitivity (first VOX level - opposite to the PTT position) is appropriate for communication in low noise levels - up to 92dB(A). B. Medium sensitivity starts the VOX with this position. Suitable for most noisy area up to 105dB(A). C. Minimum sensitivity (lowest sensitivity- position close to the PTT position) is appropriate for transmissions in high noise levels (up to 130dB and requires an increased voice signal in order to activate the transmitter. Note: When transmitting, you should hear your own voice through the speakers. 5. Suggestions for proper operation: A. It is recommended to use the PTT to transmit if you have a free hand.. B. When using VOX mode, speak continuously and avoid silent periods between words. C. When you receive a transmission, the PAWN blocks VOX transmission, PTT is always available. 6. Should the transmitter not work properly in VOX mode check the following: A. Is the VOX sensitivity position is right for the noise surrounding you? B. Is the microphone positioned close enough to your mouth? C. Are you speaking loudly enough? D. Is the other user transmitting, or is the VOX sensitivity set so high that the transmitter is constantly activated? 7. CTCSS tone (PL Decoder/Encoder) considerations: A. The default internal dip switch position is OFF. B. If you experience interference on the selected channel, it is recommended to change the channel. If you must stay on the first channel, you move the CTCSS dip switch to ON. C. Please note: D. If you are using the VOX system with PL, expect a longer delay between beginning of speech and transmission than by using PTT. The recessives will have a delay of 1-2 seconds. There for you must extend the first word like - DDDDDDave, listen..... E. Every body must change to CTCSS ON in order for this feature to work because it affects all channels. 4 8. BATTERY MAINTENANCE AND CHARGING PROCEDURE Important: Before first use charge the battery for 15 hours. Always charge with power turned off. To save battery power, the unit is programmed to self shut-off within 60 min. if no activity, receiving or transmitting is detected. A chirp tone will be heard 30 second before shutdown. When the battery is almost empty, A number of alert short tone beep will be heard before shutdown, and the red LED light will blink. Important: For best functionality, remove hair around the ears from under the cushions to improve the acoustical seal against the head. Eyeglass temples should be as thin as possible and conform close to the head. Turn on the headset and adjust the volume for best listening level. 10. HEADSET MAINTENANCE AND USER INFORMATION In order to fully benefit from the superior noise attenuation, wear PAWN 100% of the time you are exposed to noise! Regularly clean the outside of PAWN using warm water and a mild detergent. WARNING: The unit must not be submerged in water. Do not store or place PAWN in temperatures exceeding +55 C (13O F). Do not place the unit behind a car windshield or in direct sunlight. Certain chemicals may negatively effect this product. The manufacturer can provide further information. PAWN and especially the cushions may degrade over time and should be examined regularly to v…

The standard specification limit is 2 W ERP = 33 dBm. 4.3.2 Test procedure The EUT was tested according to the substitution method with dipole antenna. The test was performed at HL open field test site at 3-meter test distance, i.e. the distance between measuring antenna and EUT boundary. The EUT was placed on wooden table, as shown in Photograph 4.3.1. Electric field power values were recorded. Then the EUT was replaced with dipole antenna connected to signal generator. The generator output was adjusted to obtain an electric field power level equal to that of the EUT. Maximum ERP was calculated from equation: ERP max = P out gen – Cable loss + Antenna gain Test results are recorded in Table 4.3.1.

(2) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f d in kHz) of more than 5.625 kHz but no more than 12.5 kHz: At least 7.27(f d – 2.88 kHz) dB. (3) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f d in kHz) of more than 12.5 kHz: At least 50 + 10 log(P) dB or 70 dB, whichever is the lesser attenuation. 4.5.2 Test procedure For test setup refer to Photographs 4.2.1, 4.2.2, 4.5.1.

Spurious emissions outside the specified bandwidth (f 0 – 12.5 kHz, f 0 + 12.5 kHz) were compared with the limit, expressed as follows: Att min = 50 + 10 log(P), where for transmission frequency F = 451.017 MHz P = 17.06 dBm = 0.05 W, and Att min = 50 + 10log 0.05 = 50 – 13 = 37 dB, refer to Figure 4.5.1, for transmission frequency F = 460.65 MHz and 469.98 MHz P = 20.06 dBm = 0.1 W, and Att min = 50 + 10log 0.1 = 50 – 10 = 40 dB, refer to Figure 4.5.2. No spurious emissions were found in frequency range 9 kHz to 30 MHz. Test results are shown in Plots 4.4.2 to 4.4.18.

For frequency 451017.5 Hz the specified limit is 1128 Hz. For frequency 460648.7 Hz the specified limit is 1152 Hz For frequency 469979.6 Hz the specified limit is 1175 Hz 4.6.2 Test procedure The EUT was set up as shown in Photographs 4.6.1, 4.6.2. The frequency stability was investigated for various temperatures in the range from –30°C to +50°C. Test results are recorded in Table 4.6.1. The EUT was found to comply with requirements of paragraph 90.213. Reference numbers of test equipment used HL 0026 HL 0493 Full description is in Appendix A.
