2. Overview and getting started

The Multicom 2 system enables simultaneous two-way communication (full-duplex) between up to 5 participants and 94 other listeners. There are three different device types:

1. Main device (Main): The central coordinator for communication. One main device is always required for each group.
2. Transmitting devices (Vice): Enable sending and receiving of audio. Up to 4 devices per group possible.
3. Receiver: Reception and playback of audio, but no talkback possible.

Fully charge all devices with the supplied charger before using them.

Connect the supplied headsets (earphones for receiver) with the socket on the top of the devices.

Switch on the devices to start communication. All devices in a group must be set to the same channel (see chapter 4.5 „Central channel synchronization“ auf Seite 16). Make sure that all devices are within range of the main device. The range is approximately 200 m and can be restricted by obstacles between the devices.

4. Operation

4.1. Switch on/off

Press and hold the button to switch the device on or off.

4.2. Volume and microphone sensitivity

The display shows the current volume (DAC) or microphone sensitivity (MIC). Use the VOL+/- buttons to change the displayed value.

To switch between DAC and MIC, release the button lock and briefly press the ⏻ button (Main) / long press the M button (Vice).

4.3. Set channel

Release the button lock and set the channel using the CH+/- buttons. The current channel is shown on the display.

4.4. Key lock

Briefly press the 🔒 button to switch the key lock on and off. When the key lock is active, the 🔒 symbol is shown on the display. The volume / microphone sensitivity can still be adjusted when the key lock is active.

4.5. Central channel synchronization

You can make the channel setting centrally on the main device for all group members and synchronize all devices in a group.

To do this, select a desired free channel on the main unit. Then press and hold the M button for about 5 seconds.

All switched-on transmitters and receivers that are not currently in an active group are configured to the selected channel. Devices that are already assigned to a group are not affected.

4.6. Mute microphone

Main Transmitter:

To mute or unmute your own microphone, press and hold the VOL+ button. Pressing the ⏻ button twice will mute the microphones of all Vice Transmitters.

Vice Transmitter:

Press and hold the FUN button to mute the microphone.

The loudspeaker symbol in the display shows the current status of the mute function.

5. External audio players

An external audio player can be connected to the main unit. To do this, connect the audio output of the external audio player to the input socket on the right-hand side of the main unit using a 3.5 mm jack cable. If you now play an audio file, it will be transmitted to all devices in the group.

8. Troubleshooting

The device cannot be switched on.

1. Make sure that the battery is inserted correctly
2. Charge the device completely
3. Contact your dealer

I can't hear my conversation partners.

1. Make sure that all headsets are connected correctly.
2. Make sure that the microphone mute function is switched off.
3. Make sure that the volume and microphone sensitivity are set sufficiently high.
4. Make sure that all devices are on the same channel.
5. Make sure that all devices are within range of the main device. Use the signal strength indicator on the display.
6. Make sure that there is no more than one main device on this channel.

I hear my own voice in the earpiece.

This is called the sidetone function and is well known in the professional audio sector. Sidetone refers to the playback of the spoken word in the headset's own loudspeaker. This allows you to better regulate the volume of your own voice (especially important with circumaural headsets). If you cannot hear yourself, you know that no one else has heard you either.
