1. PAWN 101-460 (Private Address Wireless Network) was tested and approved according the
FCC part 95 for UHF licence free. FCC ID: M5U-101-460
DESCRIPTION
PAWN 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 voice
communications in noisy environments. The unit provides intelligible speech in noise levels up to 140
dB(A)!.
FUNCTIONALITY
PAWN allows wireless communication with an optional base-station on the same frequency. The
noise-suppressing microphone efficiently reduces background noise and improves voice intelligibility
in noisy environments. Transmission can be initiated by manually operating the push-to-talk switch or
hands free VOX system.
APPLICATIONS
The applications for PAWN are many; Floor shop, Power plants, Forestry, Construction, Quarry, Education and other areas where secure communication
over short distances are essential, in noisy areas.
2. OPERATING INSTRUCTIONS
Simplified controls make PAWN Headsets easy to use and simple to set-up. A four-position switch
selects the operating mode, either VOX /PTT or PTT. Rotary switch controls On/Off/Volume. Fourposition rotary switch for easy pre-set frequencies changing.
PRODUCT LAYOUT
1. Volume and On/Off control for
adjusting the volume level in the
headset.
2. 4-way switch-VOX/PTT setting with
three alternatives for adjusting VOX
circuit’s sensitivity, to ensure "HandsFree" correct microphone activation
in relation to external noise levels.
The PTT position which is activating
via the ”talk” button.
3. Frequency setting, a four -position
pre-set channels.
4. Charging socket.
5. PTT - ”talk” button for manual
transmission.

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 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 mod, you and all other recipients will hear a
beep tone.
ADJUSTMENT OF THE VOX SENSITIVITY:
• Maximum sensitivity (first VOX level) is appropriate for communication in low noise levels. A
low voice signal will activate the transmission.
• The third VOX level (lowest sensitivity) is appropriate for transmissions in high noise levels and
require an increased voice signal in order to activate the transmitter. The optimum choice of
sensitivity adjustment is dependent upon the actual noise level.
• When manual operation of the transmitter is desired, the VOX/PTT switch must be in PTT
position. 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 is
constantly 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 PROCEDURE
Important:
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 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.
4. Hard Hat Attachment
Slide the hard hat attachment into the hard hat slot and press down until it
snaps into position. When the cups are in either store or ventilation
position, the operating position is accomplished by pressing the cups
against the head until the clicking sound indicates that the cups are in
operating position. In order to prevent leakage, ensure that the neither the
cup or the suspension touches the hard hat when the cups are in the
operating position.
5. HEADSET MAINTENANCE AND USER INFORMATION
PAWN must be worn, adjusted, cleaned and maintained in accordance with the instructions in this
manual.
♦ In order to fully benefit from the superior noise attenuation, wear PAWN 100% of the time you are
exposed 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 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
verify that they are not cracked or otherwise damaged. Replacement cushions are available. For
cushion replacement gust pull off the old ones. Snap in the new cushions.
Important- If these instructions are not followed properly, the noise attenuation properties and
functionality of the unit may be negatively effected.

INFORMATION REQUIRED BY E.P.A.
The level of nose entering a person's ear, when hearing protection is worn as directed, is closely approximated by the difference between the A-weighted
environmental level and the NRR
Example:
1. 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 of
this device will reduce its effectiveness in attenuating noise. Although hearing protectors can be recommended for protection against the harmful effects
of impulse noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the
protection 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 ACCESSORIES
Two easily replaced cushions and damping pads. The replacement cushions are easily installed with a simple press-and-snap function. It is recommended
that 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 applied
directly on the hearing protector cushions. Package consists of 100 pairs of pads.
