WSM7310
Ultra Distance Wireless Device
Our WSM7310 professional wireless audio frequency transport of GM series wireless
hearing aid tool enables you to hear distant soulds. This unit uses high tech
and innovative circuitry, US ASIC and STD installation process. It is used for
audio trnsmission in differnt industriessuch as in Security monitoring systems,
tourism industry, interviewing situations, audio visual education, field expedition/exploration
and so on.
Pick up sensitivity:
The normal human ear can hear voices or sound of 5db to 25db. This unit has
a sensitivity of 12db! Pick up sensitivity of this product is equivalent to
hearing whispers and breathing 6 feet away in a quiet room. For the high pick
up sensitivity use this product in areas where there is not a lot of eterior
noise in the surrounding.
Transmission distance:
This index will be greatly affected by many factors such as weather, wind, barriers
etc. Actual factory tests clocked this unit at up to 6000 feet. However in non
lab conditions on a nice normal sunny day this unit should do well at half that
range.
USER INSTRUCTIONS:
- Switch unit to ON position on the transmitter. Then place the transmitter
to where you expect to have best sound pick up. The transmitter should be atleast
15 feet away from the receiver.
- Now turn on the receiver and extend out the antenna. Plug in the headphone
into the receiver and turn on the volume/tuning dial until you have achieved
ideal volume and reception.
Connecting recording device to receiver:
- This unit can be connectged to a recording device that will allow you to
record and also listen at the same time. To do that you will need a 3-way ply
which will allow you to connect your headphone as well as recording device.
If you dont have one then you can just record the recording device and playback
the recording later.
IMPORTANT NOTES:
The distance between the sound pick up and the sound source will determine
the clarity and the differentiation rate of the sound.
Do not use this product in locations where radio interference serious and where
there is very loud back ground noise. You will not get good results. The quieter
the environment, the better the pick up level.
Do not put the transmitter near appliances such as refrigerators, television
etc. Also avoid putting it directly next to metal barriers so as to improve
your receptive distance.
This product should not be used for illegal eavesdropping as that is not the
intended use!
