1 Selection Keys and LED’s
Depending on the individual paging station model, 10, 20, 30, or 50 selection keys with corresponding LED’s
are provided. The selection keys are used to pre-select areas or groups for the reproduction of messages,
gong or alarm signals, vocal messages, or to assign programs (pressed once = ON, subsequently pressed =
OFF). The LED’s indicate the momentary selection status (also refer to the paragraph “indications”). It is also
possible to assign special functions or no function at all (no function assigned) to the selection keys. Assigning
functions is performed during the configuration procedure via PC.
Note:
When shipped, these keys are factory pre-set as area selection keys, where key 1 –
area 1, key 2 – area 2, ..., key n – area n.
2 ALL key and LED
The ALL key allows the selection of all programmed areas at once for transmitting messages, gong or alarm
signals, vocal messages, or to assign programs. One time pressing selects all areas. The corresponding
LED’s and the ALL LED are lit. Subsequent pressing cancels the selection.
3 CANCEL key
This key offers different functions, depending on the actually selected operation mode, e.g. cancel calling
pattern or cancel program-assignment. Which function is carried out at times is explained in detail in the
paragraph OPERATION.
4 GONG key (ESC) and LED
Pressing this key starts the transmission of a gong signal in the pre-selected areas or groups. The GONG LED
lights or blinks during the transmission of a gong signal. What kind of gong signal is being transmitted is
defined during the configuration procedure. Pressing the STOP key cancels the reproduction of the gong
signal.
While in setup-mode, this key is used to return to ‘normal’ user mode (ESCAPE = leaving setup-mode).
