1.2.3 LED indication keys
The keys with LED indications are arranged in eight pieces in a row. For any key in the
communication system software, various communication functions or local control functions
of DIS can be set (for example, adjusting the volume of the built-in speakers, switching the
hands-free mode to communicate with the headset).
Each key has a backlight with two LEDs installed under it. The LED indication modes for
each key, including the direct call keys, are set from the control panel.
The most popular are the following indication options:
When the key is pressed, the backlight turns on while the key is held;
The first press of the key turns the backlight on, the second time it turns it off;
Frequent flashing of all LEDs - no connection to the control panel;
Rare flashing - an incoming call from the subscriber assigned to the key;
In case of outgoing call the LED indication has solid light.
The group of LEDs for the key is switched in series, protection against breakage or
breakdown of one of the LEDs is provided.
DIS keys additionally have increased mechanical strength, wear-resistance, and
durability. Under the transparent cap of each key, you can place the necessary inscription. To
do this, with DIS disconnected, hold the keycap over the top and bottom flat faces, pull it
slightly toward yourself until the side catches of the cap come out of the housing cover. After
that, the top cover of the cap can be separated from its base and the plate with the inscription
can be inserted inside. Then collect the cap back and latch it and put it back on its place in the
cover of the unit enclosure.
