Always Latched When you select Always Latched for a channel, the beltpack’s
microphone locks on permanently for that channel. Pressing the talk button has
no effect.
As in the previous option, you should use this option only for environments in
which you know that headsets are not left connected at power down, because
acoustic leakage and feedback can result when the system is powered back up.
You cannot use the remote-mic kill option if you activate Always Latched for a
channel.
No Operation When you select No Operation for a channel, pressing the
beltpack’s talk button does not affect the microphone for that channel. This
option is used mostly in listen-only applications.
TALK FUNCTION OPTIONS FOR A DUAL-CHANNEL BELTPACK
Figure 8 shows the talk function options for a dual-channel beltpack. You select
an option by clicking it. Note that these choices are mutually exclusive: you can
only select one option at a time. When you click an option’s check box to select
it, the other options’ check boxes automatically clear.
Figure 8: Talk Function Options for a 2-Channel Beltpack
One Channel at a Time When you select One Channel at a Time, you can talk
on either beltpack channel, but on only one channel at a time. For example, if
you latch Channel A and then press the talk button to speak on Channel B,
Channel A’s talk function deactivates. You can then talk on Channel B.
Either or Both Channels When you select Either or Both Channels, you can
talk on one or both channels at the same time. Clear-Com programs this option
into all 2-channel beltpacks as the default option.
Bounce Back is an exclusive Clear-Com feature. This feature allows you to
“interrupt” a latched talk function. For example, if you latch Channel A on a
beltpack, you can momentarily interrupt the “latch” by pressing Channel B’s talk
button to speak on Channel B. When you release Channel B’s talk button,
Channel A goes back to its original state: active and latched.
“Bounce Back” operates in three ways which correspond to the three selections in
the Talk Function area:
• Channel A bounces back when Channel B is latched.
• Channel B bounces back when Channel A is latched.
• Either channel bounces back, depending on which is latched first
