4 Users Ian Coley British Olympic Shooting Coach I found that gave me not only good protection from noise, they were also a great help in being able to have a conversation with other shooters. I have found them very comfortable to wear for long periods, and they are much better to wear than ear muffs because they give you the advantage of being able to hear various noises from different directions. Mark Stone Magazine Editor & Firearms Expert Having worn a pair of for the past few months, there s no way I d go back to wearing anything else. The performance exceeds Puretone s description whilst the ability to detect approaching pheasants literally can, and has to be heard to be believed. Mick Nicholson Shooting Instructor & Champion Shot From hearing the instant the clay leaves the trap, the moment a pheasant first beats it wings to enabling a full unhindered conversation with my numerous shooting clients and pupils, increase the senses whilst 100% protecting my hearing at all time.

6 Digital Technology utilises the latest technologies and algorithms to control the level of sound within the ear. In addition, a push-button switch ( 2 only) is used to select one of two programmes. 1 are simple to operate while 2 offer greater flexibility and enhanced performance for each environment. 1 devices are programmed to achieve mixed protection for game and clay scenarios. 2 devices have an additional push button to select between two programmes: Programme 1 (Game) Optimised for game shoot where there are intermittent shots. This configuration also helps by amplifying sounds such as wings flapping, thus providing the shooter with advanced warning of approaching quarry. Programme 2 (Clay) Optimised for clay shoots where there are continued shots. This system has been designed to allow more flexible noise suppression. Page 6

7 Your (a) Volume control & on/off switch The volume control is used to set the desired listening level and turn the devices on/off. The output is, however, limited and will not exceed uncomfortable levels (for a typically normal ear). It is, nevertheless, recommended that the instruments are not used on full volume for prolonged periods, but at a comfortable listening level only. The function of these devices is to act as a noise plug and not a hearing aid. (b) Battery tray Allows easy access to the battery to facilitate replacement. Place a fingernail under the notch, then lift to open the battery tray for battery replacement. (c) Microphone The microphone is positioned in the helix of the shell and the ambient sounds are picked up and fed into the instrument. The ear provides wind noise reduction. (d) Push-button switch ( 2 only) Pressing this button will allow the user to toggle between memories. A single bleep indicates programme 1 (Game) and a double bleep indicates programme 2 (Clay).

13 Operation Fit your into each ear, ensuring they are fitted correctly and comfortably. Switch the devices on using the volume/power switch and adjust the volume to a comfortable level by using your finger tip to rotate the control (this will typically be between the black and green dots). Never pinch the volume control/power switch with your fingers/fingernails as this can cause damage. Once they are switched on, you will be able to hear sound as normal; however, when the gun is fired the device will automatically reduce the volume of the shot to a safe and comfortable level. After the gun shot has passed the volume is automatically returned to normal. These volume adjustments take place quickly so perception of ambient sound and conversation is unaffected. Left Ear (Blue) Off On Right Ear (Red) Off On Off - noise plug (no amplification for trapshooting) Just On - low level amplification. Green Dot - gain for quiet sounds, attenuating high levels. (Typical operating position) Red Dot - full volume - offers some additional gain Some people may already have a mild hearing loss so the may help with conversations on the shooting ground. Set the volume between the green & red dots at a comfortable level. Page 13

The environment inside the ear can be hostile for the instrument. Earwax and moisture can cause problems with the device if cleaning is not performed on a regular basis. Wipe the instrument each time it is removed from the ear with a dry cloth to remove any foreign bodies. On the following pages you will find some useful tips on how to look after your new instrument.
