How to operate the charger

The Unite CDD-8/4 and Unite CDS-4/2 Cockpit chargers are used to charge the batteries in the Unite transmitters and receivers and to transfer the pairing information from the transmitters to the receivers.

The Unite CDD-8/4 Cockpit desktop charger has 8 charging compartments of which 4 are combined compartments for charging a handheld transmitter or bodypack device.
The Unite CDS-4/2 Cockpit desktop charger has 4 charging compartments of which 2 are combined compartments for charging a handheld transmitter or bodypack device.
The Unite DS-4/2 desktop charger is only used for charging the batteries in the transmitters and receivers. It has 4 charging compartments of which 2 are combined compartments for charging a handheld transmitter or bodypack device.

Mains connection

Connect the AC adapter with the power plug to a power outlet and with the DC plug to a 12 V DC
socket of the charger.
The charger has no separate on/off switch and is immediately ready for use.
When the device is not in use, remove the mains plug from the power outlet. Make sure that you do not pull on the cable, but on the power plug.
Make sure that you connect only the supplied power supply unit to the Unite CDD-8/4, Unite CDS-4/2 and Unite DS-4/2 charger (refer also to “Supplied accessories”). The internal pin of the DC socket of the Unite CDD- 8/4 has a different diameter as the pin of the DC socket of the Unite CDS-4/2.

How to insert the transmitter/receiver into the charger

Make sure that you insert the transmitter and receiver into the charging compartments so that the charging contacts of the transmitter / receiver are in contact with the charging contacts in the charger. The status display on the transmitter/receiver flashes green during charging.

Establish pairing – Unite CDD-8/4 and Unite CDS-4/2

Transmitters and receivers must be paired so that they can communicate with each other. For a successful pairing the channel name, group ID and audio encryption key are required. The required audio encryption key is generated in the Unite CDD-8/4, CDS-4/2 Cockpit desktop charger or via the Unite Manager software and during the pairing process it is first stored on the cockpit case and then it is transferred to the transmitter and receiver in the charging compartments.
There are three different ways to pair the Unite transmitters with receivers:

Via an individual charger (refer to the following description or system manual online).
Using the Unite Manager Software on a PC (refer to the Unite Manager Software manual or system manual online).
Via dynamic channel search (refer to system manual online, chapter “Special functions”.
The group ID refers to devices that can be combined to a virtual group. For example, all devices of a building, a travel group or a conference room.

Use with the group ID 150 – 256
By default, the transmitters and receivers are supplied with the group ID 256. A common factory-set audio encryption key, which cannot be changed, is used for the group ID range of 150 to 256.
The audio encryption key ensures additional security against unauthorised listening during the wireless transmission. Due to the factory-set audio encryption key the devices within the group ID range of 150 to 256 can connect to each other without pairing via the charger. In this case receivers can connect to transmitters via the dynamic channel search.
Example: Via the dynamic channel search, a receiver which is set to the group ID 160 will find all transmitters which are active and also set to the group ID 160. The receiver can connect to a transmitter without pairing. The receiver will not find transmitters beyond the set ID range of 160.
Attention: When using several transmitters (e.g. Unite AP4 and several Unite TP) with the same group ID at the same time, make sure that the individual channel names differ from each other! Otherwise this can cause connection problems with the receivers!

Use with the individual group ID 1 – 149
If several receivers are to be divided into different groups with an individual encryption, for each group an individual group ID between 1 and 149 can be assigned. A separate audio encryption key is generated for an individual group ID in order to ensure additional security against unauthorised listening during the wireless transmission. This audio encryption key is generated during the pairing process, stored in the charger and transmitted from the charger to the transmitter and receiver, along with the channel name and group ID.
Since the audio encryption key is not transmitted via radio, it cannot be read out. This gives the system maximum security against unauthorised listening.
The receivers can only connect to a transmitter with which they have been paired via the charger. If the group ID is subsequently set manually on a receiver which has not been paired, no connection can be established to the transmitter with the encrypted group ID, because the receiver does not have the audio encryption key.
In order to perform a simple pairing, proceed as described in the following:

Set the desired group ID and channel name on the transmitter you want to use for pairing. Refer also to chapter “Set group ID” and “Set channel name” of the “Unite TP – Bodypack Transmitter” or “Unite TH – Handheld Transmitter” quick start guide.
Insert only one transmitter into the charging compartment of the charger. If multiple transmitters are inserted into the charging compartments, the pairing will not start and the status indicator in the charger will display an error (see table). Further transmitters must be configured as sub-master so that they can be paired with a transmitter configured as a master. Furthermore, you can connect another transmitter / receiver to the USB port on the charger when using a USB cable type C.
Insert one or more receivers into the charging compartments of the charger to be paired with the transmitter. You can also connect another receiver to the charger using the USB port . Remove all receivers that should not be paired. If there is no receiver in the charging compartments, the pairing information is stored in the charger. This is used for later pairing without connecting the transmitter to the charger.
In order to transfer the pairing information from the transmitter to the receivers in the slots and to the charger itself for future pairing, press and hold the “Pair/Reset” button on the charger for more than 2 seconds. When the “Pairing Status” indicator flashes yellow, release the button to perform a pairing. Mobile devices that are now being paired indicate this via a status indicator that illuminates yellow. After successful pairing the “Pairing Status” indicator will permanently illuminate green to display that the pairing information is now also stored in the charger.
If you want to pair other receivers, remove the transmitter (Master) and all receivers from the charger and press the “Auto Pair” button once. The “Pairing Status” indicator will illuminate yellow. Insert the receivers that are not yet paired into the charger. The pairing information is immediately stored in these receivers. The “Pairing Status” indicator flashes yellow and displays the active pairing process. On the devices that have received the pairing information, the status indicator lights yellow for about 10 seconds. As soon as the “Pairing Status” indicator is permanently lit yellow, the pairing process is complete and you can remove the receivers from the charging compartments.
In order to end the “Auto Pair” function, press the “Auto Pair” button once. The “Pairing Status” indicator will illuminate green to indicate that the pairing information is stored in the charger.
The “Auto Pair” function is not possible, when no pairing information is stored in the charger. In this case the “Pairing Status” indicator flashes red five times.
Switch on the transmitter and a receiver to check whether the pairing was successful. When the devices are successfully paired, the status indicator of both devices will illuminate green and the receiver should display the channel name of the transmitter.
In order to delete the stored pairing information, press the “Pair/Reset” button until the “Pairing Status” indicator first flashes yellow and the goes out.

The “Operating Status” indicator on the charger shows the following information:

Indicator light	Operating status
Off	Device is switched off
Green	Device is ready to use
Flashing green/yellow	Device is being localised
Flashing red rapidly

Charging

If pairing is not required and you only want to charge the transmitter and receiver, place the transmitters and receivers in the appropriate charging compartments without activating the pairing process via the “Pair/Reset” or “Auto Pair” button.
If the stored pairing information is no longer needed, you can also delete it by pressing the “Pair/Reset” button for more than 5 seconds. When the “Pairing Status” indicator goes off, the pairing information is deleted.
Insert the transmitters / receivers into the charging compartments so that the charging contacts of the transmitters / receivers have contact with those in the charging compartments.
Charging will start automatically.
The state of charge of the batteries is indicated by the LED of the appropriate transmitter / receiver:
Indicator light| Charging status
---|---
Off| Device is switched off
Flashing green slowly| Charging 0 – 100%
Green| Battery is charged
Flashing yellow slowly| Pairing information is being copied from the transmitter
Yellow for 10 seconds| Device information is copied successfully to charger/devices
Flashes red slowly for 10 seconds|
- Too many transmitters in the charger when pairing is initiated
- Other pairing error
  Flashing green/yellow rapidly| Device is being localised
  Flashing red rapidly| Charging error
  Red| Firmware update is performed

Conditioning the battery

In order to achieve the maximum capacity of the battery, we recommend discharging the transmitters / receivers completely to carry out a complete charging cycle afterwards.
This also increases the accuracy of the battery indicator on the display of the Unite transmitters / receivers.

Automatic Firmware Update with Unite CDD-8/4 and CDS-4/2

By using the Unite Cockpit charger you can upload firmware updates to Unite transmitters / receivers.
The Unite Cockpit desktop charger is factory set with the latest firmware for transmitter / receiver at the time of delivery. If you charge transmitters / receivers with older firmware with the charger, the firmware is also automatically updated. This ensures that the charger will work properly with the transmitter / receiver.
During the firmware update the status indicator light of the Unite transmitters/receivers will illuminate red. This process will take approx. 5 minutes. During the firmware update do not disconnect the charger from the mains. Should the process take longer than 10 minutes, turn the Unite Cockpit charger off and on again. The update process will then restart.
You can check the update on the transmitter / receiver:

Attention: Please note that after a successful update to a new firmware version, the Unite transmitters / receivers are no longer compatible with older firmware versions.

Reset factory settings of the charger

If you want to restore the factory settings of the charger, press the “Reset” button on the rear of the charger. The charger will restart and restore the factory settings. A reset restores the following information:
- DHCP Setting back to “Use DHCP”
- Static IP address back to default setting 192.168.1.101
- Static Subnet mask back to default setting 255.255.255.0
- Static Gateway back to default setting 192.168.1.1
- Delete/deactivate the individually stored settings of the mobile devices (portable devices, i.e. bodypack,
- handheld).
- Deleting the stored pairing information
- Restoring the factory settings does not delete the pre-installed firmware update images!

Service mode

For maximum operational safety, the Unite Cockpit charger is equipped with a so-called service mode.
This means: If the device is disconnected from the mains within 15 seconds of being switched on (e.g. by accidentally switching it off), the device starts in a service mode and checks itself. This takes about 1 minute and is indicated by a red operating display on the rear of the charger. The Unite cockpit desktop charger then returns to the normal operating mode. This is indicated by a green operating display.
