4000 Digital Series II Issue 1.4 Panel User Guide
STA0380 Page 21
3.5.10 Loudspeaker
Audio is output from the loudspeaker unless the Headset Select is engaged.
3.5.11 Headset Socket (XLR 5 or DIN 5)
The 5 pin Headset Socket is used to connect an optional headset for use when the gooseneck
microphone and panel oudspeaker are not required.
(Headsets should be used in areas where a number of control panels are used in close proximity; this
should avoid any possibility of howlround (audio feedback) occurring)
3.5.12 Shift Pushbutton
The Shift pushbutton toggles between the Main Page and the additional DAK assignments of the Shift
Page. The red LED will flash when a call is detected for an assignment on the page not currently
displayed. When that page is accessed, the LED will illuminate.
NOTE: This will only operate if Extension Panels 1 and 2 have not been configured.
3.5.13 Info Pushbutton
Press and hold the pushbutton to display panel configuration information, identifying the following data:
CURRENT MAP NAME
1. Map Name.
PANEL POSITION
2. Directory Port Number.
3. Four Character Mnemonic (short name).
4. Description (long name).
NETWORK INFORMATION
5. System to which panel is connected.
6. Systems which exist on the network. A flashing number indicates a system number which the
configuration was expecting to exist but has not been detected on the network.
A panel fitted with the PDE4537 options card can be connected to a powered exter-
nal loudspeaker.
Contact Vitec Group Communications for suitable External Loudspeaker options
Your panel loudspeaker reduces volume automatically when a talk key is pressed.
This is to help reduce the chance of howlround (audio feedback) occurring.
Consult the Vitec Group Communications Installation Guide for further details.
