Pro Ears Radio Circuit Image

OPERATION:

Adjust  Fit – (ALL PRO EARS MODELS) The headband may be adjusted to ensure the cups fit correctly around the ears by sliding the headband apart. With the slider arms fully closed place the headband directly in the middle of the head.  Slowly adjust one slider arm at a time as needed to ensure each cup is fully covering your ear. The two slider arms should be equidistant from the headband to ensure the best fit. Be sure the headband is resting snuggly against the top of your head. The special, replaceable ProForm Leather™ Sealing Rings are made for maximum comfort and noise protection.  There should be no gaps between the ear seal and your head.  For best fit ensure your hair is not under the ear seal.  To test for a good seal, run your index finger around the area between the ear seal and your skull and ensure there are no gaps.

Batteries – (All PRO EARS electronic models) come equipped with four ‘N’ size 1.5 volt batteries, two for each cup (some Pro Tac Gold models operate on Lithium 123a batteries). Alkaline batteries provide the best service. To install, turn the volume controls to the “Off”’ position. Carefully pull  open the foam flap on the inside of the cup to reveal the battery holder. Remove the old batteries, insert the new batteries with negative to negative and positive to positive side. The correct polarity is marked in the battery holder. Once batteries are installed, carefully replace foam in the ear cup. We recommend the volume controls be turned to the ‘Off’ position when not in use.  Gold Series models have an Auto Shut-Off feature which will help save battery life if you forget to turn off the unit.

Adjust volume – (ALL PRO EARS ELECTRONIC MODELS) Before putting on your Pro Ears turn the two Volume Control knobs to the ‘Off’ position. Turn on the Volume Controls and adjust as needed for comfort. We recommend to adjust each Volume Control separately.  Turn on the right side only.  Adjust the volume so that you can hear your external environment as if you were not wearing a hearing protector.  Without further adjustment to the volume, remove the right cup from your ear and adjust the left Volume Control knob until you can hear as if you were not wearing a hearing protector. Place both cups on your ears.  Both sides should now be adjusted for true stereo sound based on your individual hearing ability and purpose.  To increase the Gain, slowly increase the Volume Control.

Changing the headband – One of the advantages of Pro Ears hearing Protection is the modular construction.  The headband is designed to provide optimal comfort without sacrificing performance.  Over time the headband can become elongated and reduce necessary compression for good performance. Replacement headbands are available at www.proears.com . To change the headband simply separate the yoke from the cup by slowly pulling the prongs with steady pressure while slightly rotating back and forth, one at a time, from the grommets on each side of the cup. (DO NOT separate the yoke from the headband sliders as these are VERY difficult to reconnect!). Replacement headbands will be shipped with yoke and sliders connected.  Be sure not to lose the grommets on each side of the cup ass these are necessary to maintain optimal performance.

Changing the ear seals – The high performance ear seal should be replaced if the outer surface becomes stiff, cracked or damaged.  Depending on use, storage and wear conditions we recommend the ear seals be replaced every 6 to 18 months.  New ear seals  and hygiene kits can be obtained at www.proears.com.  To replace the ear seal simply insert a flat head screw driver inside the cup, between the hard plastic flange of the ear seal and the cup and give a slight twist.  The ear seal should separate from the cup with a gentle motion.   Do not pry on the soft Pro Form ™ ear seals . Be careful not to damage the electronics or the speaker.

Program (Gold Series Only) – THERE ARE MULTIPLE GENERATIONS OF “GOLD SERIES” MODEL CIRCUIT BOARDS. THE BOARD LAYOUT HAS CHANGED (LOCATION OF THE JUMPERS AND PINS) AND THE “SPEAKER” ADJUSTMENT HAS BEEN CHANGED TO “AUDIO SELECT”.  THE “GAIN” ADJUSTMENT HAS REMAINED THE SAME.  THE PROCESS TO CHANGE THE PROGRAM HAS NOT CHANGED.  PLEASE REFER TO THE CORRECT INSTRUCTION BASED ON THE LABELS ON YOUR CIRCUIT BOARD.

Generation III circuit board labeled “AUDIO SELECT” AND “GAIN”

Pro Ears Gold Series models have two internal circuit board settings. Pins or jumpers are used to program the circuit boards for optimal sound quality from external sources and GAIN settings. The internal settings are completely independent of the outer volume control knob.
