Wallet Wireless System mainly is used for the occasions of being searched from top to

bottom, for where and when nobody can carry any walkie-talkie, mobile phone or theother obvious wireless device and its accessories.

All the wireless devices and their accessories on the wearer of invisible wireless earpiece

can be put into an ordinary wallet, that is, a Wallet Wireless System. The integrated circuit

board is so thin and small that it leaves the wallet enough space to contain necessary

money, business card and ID card, etc., which also make the wireless system disguised

very well. A hand-held wireless transmitter also is included in the system, by which the

speaker from far away can transmit orders to the special wallet, and then transfer to the

wearer of invisible wireless earpiece.

The wallet-shaped covert wireless communication system can be divided into two

specifications, that is, general frequency and special frequency. The former can use the

ordinary walkie-talkie as its transmitter.

How to Choose Communication Equipment and its Accessories

1. EDIMAEG CS-205 can replace all the wired and wireless earphones originally

attached with the communication equipments, such as mobile phones, wireless

interphones, micro recorder, computer and even MP3, etc. For TWO-WAY system,

most people like to choose mobile phones as its communication equipment, and set it

in the state of automatically answer or acoustic control, that is, you dont need to wait

any more, and while you listening to the call you also can answer it. Wireless

interphone is very necessary for teamwork, because it can make group-call and the

whole operations of it is very simple and easy.

2. The commonly-used inductive accessories mainly are Waistband, Neck loop,

Induction Coil and Bluetooth-Transmitter, which can send information hidden and

wirelessly to earphone. Each of them has its different feature; we should choose them

according to actual use.

Waistband

NeckloopInduction Coil

3. Generally speaking, the induction of Waistband is very strong, and its inductivedistance is also very far (20--150CM), it is very ample on many occasions. Neck loopand Induction Coil is very small and easy to use, but its electromagnetic field intensity

is rather weak, it is only suitable to work with EDIMAEG CS-205 under quietenvironment. Bluetooth-Transmitter can wirelessly connect with any communicationequipments with Bluetooth, such as Mobile phone, computer, MP3 and etc. And with it,the wearer can move very freely.

4. Except Bluetooth-Transmitter, through a proper terminal, Waistband, Neck loop andInduction Coil can connect with selected communication equipments, and thenwirelessly transfer the signal to EDIMAEG CS-205. Generally, the signal is from theexternal plug of the selected communication equipments.

5. Please note: For different communication equipments, the specifications and

connections of their external plugs are also different. Improper plug will cause silence

or it only can hear but cannot answer and vice versa.

Cleaning and Maintenance

According to the use frequency, you can use soft brush to clean the earwax and dust on

the surface of the earphone and battery compartment.

While brushing, youd better use soft cloth, which can do cleaning better for your

earphone. Please dont use solvent to clean the liquid or oil attached on your earphone.

If you carelessly get the invisible earphone wet, to put it into an oven, microwave oven or

use an electric hair-drier to dry it will damage the earphone. You should remove thebatteries immediately, and open the battery door for air drying, then put the earphone on

safe and towel-matted place.

EDIMAEG CS-205 is so small that we always forget its existence. Therefore, when you

clean the earphone or replace the batteries, to avoid its possible falling on the hard

surface and then being damaged or lost, please place the earphone on the towel or soft

cloth matted table or desk. Dont expose the earphone under the strong sunlight. If you

dont use it, please store it in a safe place, and away from drugs, pets and kids. Dont try to

repair the earphone by yourself, if necessary, please consult the professional technician

for maintenance.

The Test for Silence or Low Volume

1. First test the functions of EDIMAEG CS-205. While installing the batteries, you can

hear a light sound of sha-sha, just like the sound of water flowing. Then you wear the

earphone to approach a working TV or computer screen (not LC specification), when

the distance is about 30cm, you should hear an unwanted sound of du-du.

2. If EDIMAEG CS-205 is confirmed working well, it must be the infrequent uses of

earphone plug of the mobile phone (or other communication equipments) cause the

contact point rusty, and then the earphone fails to transfer signal. If it is the case, you

just need to try more inserting.

3. The silence causes by the mismatching between the plug of the inductive accessories

and the socket of the selected communication equipment.

4. The volume of EDIMAEG CS-205 can be controlled by the volume button of the

selected communication equipment. You can turn up the volume.Please note: on

normal, Waistband can obtain higher volume than Neck loop or Induction Coil can do.

If you still need higher volume, you change your Waistband to the strong specification

of 1212# or1512#. Certainly, you also can move up Waistband to your chest.
