Bolero is a 6 channel wireless intercom which allows users to communicate in groups or party lines.
Keys for channels 1 – 4 are on the face of the beltpack screen and keys for channels 5 & 6 are on the side of the beltpack at the bottom.
channel types
Channels on the beltpack can be configured as
- Listen – channel needs to be active (turned on) to hear audio.
- Talk – channel needs to be active to talk to the partyline.
- Talk & Always Listen – Audio will always be heard. To talk the channel need to be active. This is the normal configuration for partyline audio.
- Talk & Listen – Audio will only be heard while the channel is active. This type of channel would require a key that is capable of latching.
- Monitor – A monitor key will listen to the audio of a destination when its microphone is active.
key modes
Beltpack keys have three modes
- Momentary – key must be pressed and held to activate the channel
- Latching – pressing the key turns the channel on and off alternately.
- Auto – a short key press (<2 seconds) causes the channel to latch and a long key press is momentary.
listen channels
These have to be turned on to hear audio.
A yellow bar above the channel indicates the beltpack is listening to audio on that channel. Listen channels are normally latching otherwise the channel would need to be held to hear anything.
Talkback Channels
These channels are talk and always listen so that users will always hear the audio and can press to talk back. These channels are normally set to Auto but may be restricted to momentary to prevent users latching on.
A green bar above indicates the presence of audio on the channel.
volume control
The overall headset volume is controlled by either the left or right rotary encoder.
To adjust the volume of an individual channel, press the menu button to highlight a channel pair i.e. 1 & 2, 3 & 4, 5 & 6.
A second and third press of the menu button will highlight channels 3 & 4 and 5 & 6 respectively.
Use the corresponding left or right encoder to set the volume level.
