wireless covert earpiece/mini earphone

covert earpiece

Product Brief

Conceal Wireless Earphone is a wireless electromagnetic wave inductive and receiving device, which designed completely according to human ear canal. I t composes a covert signal transfers and receiver system with the electromagnetic wave inductive module, highly sensitive microphone, wireless PTT or wired PTT. The advantage is wearing comfortable, compact configuration, simple operation and good concealment .Mainly apply to the working condition because of expositing earphone and earphone body inconveniently, such as antiterrorism, criminal reconnaissance, radio broadcasting, theatrical performances etc.

Product Characteristic

★ Small,good arts and crafts,excellent concealment .

★ Streamlined human based designs to wear more safe and comfortable.

★ Use of micro-electronics circuit design, ensure high sensitivity and good listening and obturation effect.

★ Anti-cerumen unique design, maintenance, service more easily.

★ High-Capacity batteries configured, could work for about 80 hours .

Configuration Introduction

Conceal Earphone is built with special module, shell, the battery door handles and anti- earwax net.

Compatibility

Working Principle

wireless Conceal earphone is the receiving device which be derived by electric magnetic induction, it needs to be used with the electromagnetic equipment (Induction module or Induction loop) . To constitute a covert radio talkback and control system, you need a set of drive installations suppor the use , just like two –way radio and mobile etc.

Operating Method

⒈ Battery installation

Put the raised portion down on the battery door,open battery holder , remove the label from battery and put the positive pole towards below, put battery into holder , cover the battery door.

⒉ Wearing methods

Take it with thumb and first fingers so that the tip with earwax filter upturned .put it into ear canal carefully, then try to adjust to the best according to ear canal configuration.

⒊ Remove the battery

Open the battery door slightly and remove the battery by pressing the raised portion of the door

Warning

⒈ Keep the battery in safe place and out of the child .Promptly to ask for doctor if battery and earphone are swallowed.

⒉ Use appointed model battery .Replacement and disassembly battery and any part at will are not allowed.

⒊ Don’t immerse battery and earphones into water. If there are not expressly specified for this purpose and do not use strong chemicals, cleaning solvents or strong detergents to clean.

⒋ Take the battery out of the battery holder after battery is used up.

⒌ Strong magnetic field may cause by interfere the quality of communication. Try to use far away from magnetic field.

⒍ Doesn’t use under the conditions such as gas station, which could be likely to explode, so as to avoid an explosion triggered explosive device inadvertently endanger the lives and safety.

⒎ If it is out of operation, take it to local recycle bin for disposal.

Failures Remove

⒈ No signal

Check the positive pole towards below and battery sticker has been removed.

⒉ Small voice

Check the earwax filter is not blocked.

⒊ Noise

Keep it away from the electromagnetic noise source until without noise anymore.

⒋ Constant fizzle

Change the battery for the low capacity.
