 The device consists of a tiny
code sender and a small
vibration receiver (see picture below).
The code sender is triggered by the ON/OFF button. When the On/Off button is pressed once, a pulsation signal is sent to the receiver which will vibrate once accordingly. Likewise, if the
code sender button is pressed twice, one at longer interval and one at short interval, the receiver will react accordingly.
The duration of vibration is controlled by the ON/OFF button of the code sender.
The code sender is quite similar to a morse code transmitter.
You may pre-agree with the person holding the
receiver the meanings of the vibration. For example, vibrating once means "Option 1", vibrating twice means "Option 2", one long and one short
vibrations means "Option 10".... and so forth.
The code sender is so small that it can be hidden in the palm, in the sleeve, under the elbow, in the pocket or in the shoe (using the toe to click the
on/off button).
Maximum number of vibration per second is 15 times.
A code sender may control as many receivers as you need,
provided the receivers are preset to the same operating frequency of the code sender. Up to eight groups of sender/receiver, each operates on different frequency, can be used in a location without interferences to one other.
The code sender is powered by a single button-type lithium battery Type CR1616. Whilst the
receiver is powered by a single AAA 1.5V battery.
