Each wireless terminal has three buttons. The buttons have no default functions; you must write a script
program for each button. Two of the buttons are large and easy to press. These buttons should be used for
functions that are frequently used, for example to call the next customer. The third button is much smaller
and a little bit more difficult to press. This button should be used to special functions that should not be easy
to use by mistake, for example alarms, move customers, etc.
The number of terminals that can be used in the same system has no exact limit. The risk of interference
increases with the number of terminals. The multi interface can only receive the signals from one terminal
at the same time. You should limit the risk that buttons on two or more terminals are pressed at the same
time. This risk depends on the number of terminals used at the same time and how frequently the buttons
are pressed.
The wireless terminal uses four standard 1.5 V AAA batteries but it is also possible to use four 1.2 V AAA
rechargeable batteries. It sends the code as long as any button is pressed. The transmission automatically
stops after 60 seconds to prevent drainage of the battery.
The frequency of the radio signal is 433.920 MHz or 315.00 MHz. The range without any obstacles is up to
80 m (433.920 MHz). These frequencies are reserved for all kinds of remote controlled devices. The limited
output power reduces the risk of interference between different remote controlled devices.
There is a clip at the back of the terminal. Use the clip to attach the terminal to the cloths, for example the
pockets. Press the clip to make it easier to attach the terminal.
