Basic Operation
The top Panel of the Telos Infinity INF-BP-2 intercom Beltpack includes a monochrome OLED display, two talk keys, two call keys, a menu key, and a miniature condenser microphone. There are recessed volume controls for Channel 1 and Channel 2 on the side of the unit near the front Panel.
Note - The four-channel INF-BP-4 Beltpack uses a similar layout but with four talk keys. Please see the INF-BP-4 section for more details.
Talking
To talk to a desired channel, simply press the “Talk” key. The Talk key operates in one of two modes, depending on the user’s action.
Momentary
Also called "Push to Talk". Press and hold the Talk key for longer than 1 second. The talk function will be enabled (on) if the Talk key is pressed. As soon as the Talk key is released, the talk function will be disabled.
Latched
Pressing the Talk key quickly (less than 1 second) will latch the talk function on. Pressing the Talk key again will disable the talk function.
When the Talk function is active, the Talk LED located next to that channel’s Talk key will be lit.
Calling
To send a call signal to other members of a Partyline, press the Call button. The Call LED will light on all Beltpacks of the Partyline, including the Beltpack which initiated the call signal.
Listening
Adjusting the Listening Volume
Each channel has its own individual volume control on the side of the Beltpack. To adjust the listening volume, turn the encoder on the side of the Beltpack nearest to the channel.
Turning the volume control in a clockwise direction (to the right) increases the volume
Turning the volume control in a counterclockwise direction (to the left) decreases the listening volume
To adjust the listening volume of the Program Input, adjust the volume encoder on the bottom of the Beltpack
