Beltstation Overview
1- Volume- CH A/B and CH C/D
Multipurpose Volume A/B and C/D control.
In Operational Mode turning the Volume control adjusts the volume of the
audio from channel A and B or C and D. Pressing the Volume control
changes the selected intercom between channels A and B, or C and D.
In Menu Mode turning the A/B Volume control allows the user to scroll the
options of the current menu screen. Pressing the A/B Volume control
selects the option.
2- Stage Button
The Stage Announce (STAGE) button re-routes the microphone signal of
the beltstation from the selected intercom channel to the base station rear
panel Stage Announce (SA) output connector. If desired, when this button
is pressed, a momentary relay contact closure is made at the Relay
connector. See Page 35 for the section on GPO Relays.
Pressing the Stage Announce button automatically enables the
microphone, regardless of Talk Button status. The Stage button settings
may be adjusted at the Stage Announce menu screen under the “Set
Controls” menu section.
3- Menu Button
Pressing MENU while the beltstation is in Operational mode will select Menu Mode and the Main Menu
screen will be displayed. Once in Menu Mode pressing MENU again, will act as an escape key and will
back out of the current menu screen moving the user up one level. Pressing the Menu button while at the
Main Menu screen will exit Menu Mode and return to Operational mode.
4- Enter Button
The Enter button operates differently depending on the mode of the beltstation. In Menu Mode pressing
the Enter button selects the current menu option and is the same as pressing the A/B Volume control. A
menu item is not selected until the Enter button (or the Volume control) is pressed.
The Enter button can also activate Wireless ISO (wireless talk around), providing wireless communication
isolated from any connected wired intercom system.
The Enter button is also one of the buttons that can be assigned to activate a Relay in the base station. It
is possible to activate the Relay whenever the Wireless ISO feature is used.
5- LCD
While in Operational Mode the LCD displays the status of the beltstation including the name of the
currently communicating base station, RF strength, battery level, and other data.
The LCD backlight and contrast can be adjusted from the LCD Adjustments menu screen under the
LCD/LED section.
6- CALL Button
The CALL Button sends a 2-Wire intercom system compatible call signal to any wireless beltstation and
any hardwired intercom device on the intercom channel currently selected with Talk enabled. The Call
signal will be routed to intercom channels indicated by the user’s active Talk button(s).
