Portable Intercom System

The CAME-NANO is a compact portable intercom device that adopts full-duplex technology, allowing multiple parties to have simultaneous conversations. It features a built-in speaker on the fuselage, which can produce sound externally, and it can also be connected to other audio devices using a 3.5mm audio jack. It offers versatile carrying options, such as hanging, clipping, or holding it by hand.

Suggestions for optimal use

When you receive NANO, please charge it before turning it on.
Make sure the devices are in off state while charging to prevent battery draining when fully charged.
When devices are near, they may generate noise. To mitigate this, press the middle button to turn off the microphone.
The intercom system consists of a master and multiple remotes. The master acts as a signal transfer station for the remotes. So in actual use, the remotes should be distributed around the master to achieve the optimal use effect.
The best communication quality is achieved when there are no obstacles between the master and the remotes. Obstructions like the human body can impact the effectiveness of the device.So we advise using an arm belt.
Some frequencies used by mobile phone signal base stations may interfere with the Nano system, causing disruptions when it is in use.
The signal antenna of the CAME-NANO is generally located around the lanyard hole area. It is important to not cover this region to ensure quality communication.
To maximize audio performance, it is recommended to use official standard headphones. The 3.5mm interface follows the OMTP standard. If you have (US) CTIA standard equipment, an audio cable will be required.

Nano with Hub Set

The Hub incorporates two Masters and one built-in Remote.
Each Master within the Hub can accommodate up to 3 Remotes.
With this configuration, a single hub enables connections for up to 10 NANO within a single system, while two hubs can facilitate connections for up to 15 NANO.
(Please refer to the pairing diagram above for further guidance.)
The hub has a micro USB port to power/charge the unit via 5V DC with a USB power supply or power bank.
When power is connected it can run directly without batteries and also charge when batteries are installed. The Hub can run alone on batteries and with one installed run time is about 8-10 hours and with two batteries installed, the run time increases to about 15-18 hours.

Battery compartment

Battery Compartment

As long as an NB-6L battery is present in the battery compartment, it will constantly supply power to the hub.
If there is no battery, the hub can also be connected to an external power supply through the USB port.
With an external USB power supply, the HUB can also charge the batteries placed inside it.

Working Indicator for M1 and M2

The working indicator aids in distinguishing the Master to which the remote belongs.
When viewed vertically from the top, the M1 and M2 indicators display the number of remotes they are connected to, with each Master capable of connecting to up to 3 remotes. Consequently, up to 6 indicators can illuminate simultaneously.
If the remote power is off or disconnects, the corresponding indicator will extinguish. For instance, if one of the remotes connected to M1 powers off, only two of M1’s indicators will remain lit, while M2’s indicators will remain unaffected.

Pairing Instructions

The product comes pre-paired, allowing immediate use upon switching on the device without any additional steps. Pairing becomes necessary only if a remote loses connection with the master.

Pairing Steps

Ensure that both the Master and all Remote devices are powered on. When the Master enters the pairing state, any remotes not powered on will be cleared from the set.
Simultaneously press the “Volume Up” and “Volume Down” buttons on the Master until the green LED indicator begins flashing quickly and the sound of “pairing” is heard, indicating it has entered the pairing state. And then activate the pairing mode of remote Nano, it follows the same pairing activation steps by simultaneously pressing the volume up and down buttons. Start by pairing one remote, once it says “your headset is connected” then proceed to pair the remaining lost remotes one by one in sequence.
The master will automatically exit the pairing state and the LED will become solid once it is fully connected with all 4 remotes.
If there are fewer than 4 remotes, you can manually exit the pairing state by pressing the master Nano “Mute On/off “button.
If you want to pair a remote with a new master, be sure to turn off the previous master that was paired with that remote before initiating the new pairing process.

Nano with Hub Pairing Instructions

These are precise pairing procedures. It is strongly recommended to follow the guide carefully and accurately for the successful operation of this unit.

Pairing
The product comes pre-paired, allowing immediate use upon switching on the device without any additional steps. Pairing becomes necessary only if a remote loses connection with the master. It is important to check the disconnected remote ID number to identify which group master it belongs to:

Master A group (Remote Hub R and Remote B/C/J)
Hub M1 group (Remote D/E/F)
Hub M2 group (Remote G/H/I)

Make sure to pair the disconnected group only. Ensure that both the master and all remote devices in the disconnected group are powered on. When the Master enters the pairing state, any remotes not powered on in the same group will be cleared.

Pairing Steps for Different Group Remotes:

Pairing Master A with Remote Hub R and Remote NANO B/C/J: (In the below two circumstances, make sure Master A, Remote Hub R, and Remote NANO B/C/J are powered on.)
If it is Remote B/C/J disconnected from Master A:

Activate the pairing mode of Master A by pressing the “Volume Up” and “Volume Down” buttons simultaneously, once the LED indicator starts flashing quickly and the sound of “pairing” is heard, indicating it has entered the pairing state. And then activate the pairing mode of the lost remote Nano. Start by pairing one remote, once it says “your headset is connected” then proceed to pair the remaining lost remotes one by one in sequence.

If it is Remote Hub R disconnected from Master A:

Press the Volume Up and Down keys simultaneously on Master A until the LED indicator starts flashing quickly to enter the pairing state.
Press and hold the middle button on remote Hub R until the Blue LED indicator starts flashing quickly to enter the pairing state.
Once they are successfully connected, the working indicator for hub remote R will become solid. The Master A will automatically exit the pairing state and the LED will become solid once it is fully connected with 4 Remotes(Remote Hub R and Remote NANO B/C/J). If there are fewer than 4 remotes, you can manually exit the pairing state by pressing the master A mute button.

Pairing the Hub M1 group (Remote D/E/F):

Ensure that both the Hub M1 and all Remote D/E/F are powered on.
Press and hold the left button on Hub M1 until the blue LED indicator starts flashing quickly to enter the pairing state.
Simultaneously press the “Volume Up” and “Volume Down” buttons on the disconnected remote Nano until the LED starts flashing quickly, you will hear the sound of pairing from the remote. Begin by pairing one remote first, then proceed to pair the remaining lost remotes one by one in sequence.
Hub M1 will automatically exit the pairing state, and the LED will become solid once it is fully connected with 3 remotes (Remote D/E/F). If there are fewer than 3 remotes, you can manually exit the pairing state by long-pressing the HUB M1 button.

Pairing the Hub M2 group (Remote G/H/I):

Ensure that both the Hub M2 and all Remote I/H/G are powered on.
Long-press the Hub M2 button to activate the pairing process. The procedure is similar to the step above.

NOTES

The Master module and remote module in the hub cannot be paired at the same time, as it may result in malfunction.
It is crucial to identify the group that the disconnected remote belongs to before pairing.
Pairing is only needed for the disconnected group, and ensure that all remotes in the same group are powered on before pairing.
