AMi Headset User Manual
1. Introduction
Thank you for choosing the AMi Headset solution.
The AMi Headset is a smart, high-performance communication headset designed for use by professional teams. AMi Headset redefines the boundaries of what is possible with short-range, critical voice-communications by wrapping together a unique combination of Bluetooth and Dynamic Mesh Communication (DMC®) intercom technologies.
Bringing in years of field experience, the new AMI Headset delivers an autonomous group-communication performance like no other solution on the market today.
Designed for professional, safety, and industrial markets, AMI Headset connects two to fifteen team members on the go. Always-on communication coupled with natural voice operation, connectivity to 2-way radios, built-in FM radio, smartphone music streaming, and hear-through capabilities provide a unique blend of top-class communication offerings.
The AMI Headset is equipped with two tactical level dependent microphones that enable situation awareness, meaning that the microphones allow some of the ambient noise through, while reducing other ambient noise to a specific, regulation-allowed level if it gets too loud. At the same time, the system amplifies low ambient noise making sure you do not need to remove your headset to hear important sounds, such as warning signals.
Operating without the need for any infrastructure, the AMI Headset maintains multi-party intercom connectivity between free-moving team members in virtually any environment. With millions of Cardo intercom products sold to date, the AMI Headset is a mature solution from day one, covering all your bases and then topping them up with game-changing capabilities.
The AMI Headset comes with the standard headband version or the helmet mount.
This User Manual describes how to use the AMi Headset, that in turn enables you to experience all the capabilities of the PRO-1 module embedded in this headset.
Important
Please read, understand, and follow the safety instructions in this User Manual prior to working with the AMI Headset.
2. Before using the device
Millions of employees across the world are exposed to excessive levels of noise at their workplace. Because of this, many suffer work-related hearing loss, tinnitus, and other related medical conditions which may have a permanent, negative effect on their quality of life.
To ensure that items of hearing protection are fit-for-purpose, and in line with the requirements of the Control of Noise at Work Regulations 2005, ear protection products for sale in Europe must meet the EN352 series of European standards. The USA/Canada require ANSI S3. 19-1974, and Australia & New Zealand require AS/NZS1270:2002.
2.1 When is hearing protection needed?
In Europe, according to the Control of Noise at Work Regulations 2005, the exposure level at which employers need to provide hearing protection is a daily or weekly personal noise exposure of 85 dB (decibels). Those who work in noise levels between 80 dB (lower action level) and 85 dB must be provided with suitable hearing protection on request. Where noise levels reach or exceed 85 dB (upper action level), suitable hearing protection must be supplied and worn.
The exposure limit is 87 dB; this figure considers any reduction in exposure provided by hearing protection. Workers must not be exposed to noise levels exceeding 87 dB whether they are wearing hearing protection or not.
The AMI Headset has been designed to comply with this certification to protect your hearing.

The level of noise entering a person's ear canal, when the hearing protector is worn as directed, is closely approximated as the difference between A-weighted environmental noise level and the NRR.
Example:
1. The environmental noise level as measured at the ear is 92 dBA. 2. The NRR is 26 decibels (dB). 3. The level of noise entering the ear canal is approximately 66 dBA.
CAUTION: For noise environments dominated by frequencies below 500Hz, the C-weighted environmental noise level should be used. Improper fit of this device reduces its effectiveness for attenuating noise. Consult the enclosed instructions for proper fit. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire. Constant or repetitive exposure to impulsive noise may lead to serious injury, including temporary or permanent deafness.
The Noise Reduction Rating (NRR) calculated from the attenuation data is 26dB. Earmuffs must be properly fitted to attenuate noise effectively. Refer to instructions.

7. Talking with Others
Your AMI Headset intercom communication functionality uses Cardo's Dynamic Mesh Communications (DMC) technology.
DMC is the best way to communicate in a group. In DMC mode, you can instantly create, or join, a dynamically fluid network of up to 15 members to communicate in full conference mode. DMC allows anyone in the group to roam freely, overtake each other, or even leave the group altogether, without affecting the ongoing conversations of the remaining group members. You can also use the DMC intercom to communicate privately with another Crew member.
7.1 How Does DMC Work?
Anyone can start a new DMC intercom group.
CREW members can join, leave, and rejoin existing intercom groups without affecting the ongoing conversation among the other group members. If a crew member goes out of range, the remaining crew members are automatically reconnected, within split seconds, to a closer crew member, bypassing the absent or remote crew member. This way, all active crew members remain connected to each other.
7.2 Intercom Operation
You can use the intercom to speak with other AMi members in your intercom group. For more information on creating DMC intercom groups, see Creating Intercom Groups on page 18.
Using the DMC intercom, all crew members in a group speak hands-free. A crew member in a group performs no additional operation to speak to, or hear, other crew members in the group.
Using the intercom, you can also:
· Chat privately with another crew member in your DMC group, see Chatting Privately on page 19. · Bridge a non-crew Headset member, see Using the Intercom on page 19. · Mute/unmute intercom groups, see Muting/Unmuting DMC Intercom Groups on page 19. · Delete intercom groups, see Deleting Intercom Groups on page 19. · Listen to music while in DMC intercom groups, see Mixing the Intercom Audio with Music Streaming and FM Radio
on page 20.
7.2.1 Setting Up and Using DMC Intercom Groups
You can manage DMC intercom groups to suit your work requirements. This includes creating groups, joining groups, leaving and re-joining groups, or changing your active group.
Intercom groups are created and deleted by a group creator. Each group can have up to 15 crew members: one group creator/admin and a maximum of 14 group members.
When creating a group, all members should be within 3 meters (10 feet) of the creator. The group continues functioning even if the creator is no longer available.
If a crew member's connection is lost, they will hear a "Group disconnected" announcement. The crew member remains part of the group and reconnects automatically once in range.
7.2.2 Creating Intercom Groups
When creating an intercom group, you must coordinate with the other crew member who will be the group creator.
To create an intercom group:
1. The group creator and all group members: Press the Intercom button for 5 seconds. The LED flashes green quickly. 2. Only the group creator: Tap the Intercom button. The LED flashes red and green quickly. 3. Other members can join the group within 2 minutes.

AMi Headset User Manual
4. After each member joins successfully, the LEDs of the joined unit and the creator's unit flash purple. After grouping is completed, the intercom conference starts automatically.
5. To stop the grouping process, press the Intercom button for 2 seconds. 7.2.3 Joining Intercom Groups You can join or rejoin to an intercom group created by another crew member. If your intercom group connection is lost, you remain part of the group. Once in range of any other group member, you automatically reconnect. If your intercom group splits with some group members remaining in range of each other, but not in range of all group members, you can continue speaking with the members that are still in range. Once in range of any other group member, you automatically reconnect. If you join a new intercom group, you automatically leave your existing DMC group. To join an existing intercom group: 1) Both you and the group creator: Press the Intercom button for 5 seconds. The LED flashes green quickly. 2) Only the group creator: Tap on the Intercom button. The LED flashes red and green quickly. The color of the flashing LED indicates whether you have been added to the group:
o Purple: You have successfully joined the group. o Yellow: You cannot join the group because it has already reached the maximum number of AMi members. o Red: Failed to join. 7.2.4 Deleting Intercom Groups If you delete a DMC intercom group, you must rejoin it if you want to connect to it again in the future.
To delete an intercom group: 1. Press the Intercom button for 5 seconds. The LED flashes green quickly. 2. Press the Volume Down button for 2 seconds. The LED flashes purple 5 times slowly, confirming that group has been deleted.
7.2.5 Using the Intercom 7.2.6 Chatting Privately You can chat privately with a specific member of your intercom group.
This option is also available using the Cardo PROmesh app.
You have two options for choosing your private chat member. Using Cardo PROmesh mobile application:

· Tap the Intercom button while bridging is active. 7.2.7.1 Muting/Unmuting DMC Intercom Groups Muting the intercom mutes your microphone and speaker from the group. Unmuting the intercom restores sound to your microphone and speaker. To mute/unmute the DMC group:
· Tap the Intercom button, wait until you hear "Mute group" and tap again. 7.2.7.2 Mixing the Intercom Audio with Music Streaming and FM Radio The AMI Headset can use parallel audio streaming to stream audio from two connected sources simultaneously, so that you can listen to your music, or the FM radio, while holding an intercom conversation. The AMI Headset automatically manages your music and FM radio volume while using intercom. Changing the volume while the intercom is active and Music/FM are in the background, changes the intercom volume. To increase/decrease the Music or FM Radio volume while connected to an intercom group, use the Volume buttons while no audio is heard on the intercom group.
