-2-1. PAWN 101-460 (Private Address Wireless Network) was tested and approved according theFCC part 95 for UHF licence free. FCC ID: M5U-101-460DESCRIPTIONPAWN is a two-way, 8 frequencies\ channels, wireless FM transceiver, rechargeable battery operated,built into a highly efficient hearing protection device, developed by HCS for secure voicecommunications in noisy environments. The unit provides intelligible speech in noise levels up to 140dB(A)!.FUNCTIONALITYPAWN allows wireless communication with an optional base-station on the same frequency. Thenoise-suppressing microphone efficiently reduces background noise and improves voice intelligibilityin noisy environments. Transmission can be initiated by manually operating the push-to-talk switch orhands free VOX system.APPLICATIONSThe applications for PAWN are many; Floor shop, Power plants, Forestry, Construction, Quarry, Education and other areas where secure communicationover short distances are essential, in noisy areas.2. OPERATING INSTRUCTIONSSimplified controls make PAWN Headsets easy to use and simple to set-up. A four-position switchselects the operating mode, either VOX /PTT or PTT. Rotary switch controls On/Off/Volume. Four-position rotary switch for easy pre-set frequencies changing.PRODUCT LAYOUT1. Volume and On/Off control foradjusting the volume level in theheadset.2. 4-way switch-VOX/PTT setting withthree alternatives for adjusting VOXcircuit’s sensitivity, to ensure "Hands-Free" correct microphone activationin relation to external noise levels.The PTT position which is activatingvia the ”talk” button.3.

-3-TRANSMITTING AND RECEIVING:The headset is in receiving mode, when it turned on by the Volume/ On/Off switch.To transmit voice makes sure that the microphone is very close to your mouth (about ½ “) and thewhite dot on the microphone is against your mouth. Push the PTT button or adjust the VOX sensitivityand start talking.After releasing the PTT or when you stop talking in VOX mod, you and all other recipients will hear abeep tone.ADJUSTMENT OF THE VOX SENSITIVITY: • Maximum sensitivity (first VOX level) is appropriate for communication in low noise levels. Alow voice signal will activate the transmission. • The third VOX level (lowest sensitivity) is appropriate for transmissions in high noise levels andrequire an increased voice signal in order to activate the transmitter. The optimum choice ofsensitivity adjustment is dependent upon the actual noise level. • When manual operation of the transmitter is desired, the VOX/PTT switch must be in PTTposition. Press the PTT switch during transmit, release for receiving.NOTE:WHEN TRANSMITTING, YOU SHOULD HEAR YOUR OWN VOICE THROUGH THE SPEAKERS.Should the transmitter not work properly in VOX mode: • Is the VOX sensitivity setting appropriate for the level of your voice? • Is the microphone positioned in close proximity to your mouth? • Is the other user transmitting, or is the VOX sensitivity set so high that the transmitter isconstantly activated? • Are you speaking loud enough?Suggestions for proper operation: • When using VOX mode, speak in a constant flow and avoid silent periods between words. • Inform the other listener when your transmission stops. • When you receive a transmission, the PAWN block VOX transmission, PTT is always available.3. BATTRY MAINTENANCE AND CHARGING PROCEDUREImportant: Before first use charge the battery for 10 hours. 1st. Always charge with power turned off. 2nd. 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 herd 30 second before shutdown. 3rd. When the battery is almost empty, A number of alert short tone beep will be heard beforeshutdown, and the red LED light will blink.
-4-Important: For best functionality, remove hair around the ears from under the cushions to improvethe acoustical seal against the head. Eyeglass temples should be as thin as possible and conform closeto the head. Turn on the headset and adjust the volume for best listening level.4. Hard Hat Attachment Slide the hard hat attachment into the hard hat slot and press down until itsnaps into position. When the cups are in either store or ventilationposition, the operating position is accomplished by pressing the cupsagainst the head until the clicking sound indicates that the cups are inoperating position. In order to prevent leakage, ensure that the neither thecup or the suspension touches the hard hat when the cups are in theoperating position.5. HEADSET MAINTENANCE AND USER INFORMATIONPAWN must be worn, adjusted, cleaned and maintained in accordance with the instructions in thismanual. ♦ In order to fully benefit from the superior noise attenuation, wear PAWN 100% of the time you areexposed to noise! ♦ Regularly cleans the outside of PAWN using warm water and a mild detergent. ♦♦♦♦ WORNNING: 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 unitbehind a car windshield or in direct sunlight. ♦ Certain chemicals may negatively effect this product. The manufacturer can provide furtherinformation. ♦ PAWN and especially the cushions may degrade over time and should be examined regularly toverify that they are not cracked or otherwise damaged. Replacement cushions are available. Forcushion replacement gust pull off the old ones. Snap in the new cushions.Important- If these instructions are not followed properly, the noise attenuation properties andfunctionality of the unit may be negatively effected.

The environmental noise level at the ear is 100 dB (A).2. The NRR is 23 decibels (dB)3. The level of noise entering the ear is approximately equal to 77 dB (A).CAUTION: For noise environments dominated by frequencies below 500 Hz. the C-weighted environmental noise level should be used. Improper fit ofthis device will reduce its effectiveness in attenuating noise. Although hearing protectors can be recommended for protection against the harmful effectsof impulse noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of theprotection attainable against impulse noise such as gunfire.NOTE: The Noise Reduction Rating is derived from testing procedures at an independent laboratory and in accordance to acceptable ANSI standards.Actual noise reduction can vary from laboratory results as labelled Protection is maximised when proper protector is selected for application.7. SPARE PARTS AND ACCESSORIESTwo easily replaced cushions and damping pads. The replacement cushions are easily installed with a simple press-and-snap function. It is recommendedthat the hearing protector cushions and damping pads are replaced with 6 month intervals Is in order to guarantee continued good noise attenuation,hygiene and comfort.Clean disposable headset protective pads – Cool II: The ultimate and comfortable alternative when using headsets in dirty environments or in extreme heat. Clean is a disposable hygiene pad that is applieddirectly on the hearing protector cushions. Package consists of 100 pairs of pads.LIMITED WARRANTYTHIS PRODUCT IS WARRANTED AGAINST DEFECTS FOR ONE YEAR FROM DATE OF PURCHASE FROM HEAD CONNECTIONCOMPANY AND AUTHORIZED HEAD CONNECTION FRANCHISEES AND DEALERS.
