2. GETTING STARTED

2.1 GETTING TO KNOW YOUR FREECOM 4+

2.2 CHARGING THE FREECOM 4+

Make sure that your FREECOM 4+ battery is charged for at least 4 hours before initial use.

To charge the unit:

1. Using the supplied USB cable, connect your computer or wall charger to the USBport on your FREECOM
4+.

● Charging with the wall charger is faster than via a computer USB port.

● Charging your unit switches it off automatically. To use your unit while it is being charged, switch it on.

(see Switching Your Unit On/Off on page 5).

While charging, the LED indicates the charging status as follows:

● Red LED on — charging

● Red LED off — charging complete

TIP: You can check the battery charge at any time by saying "Hey Cardo, battery status."

The LED flashes red three times, confirming that your unit is switching off. The speaker plays a
descending tone and a voice message, "Goodbye".

2.4 USING YOUR FREECOM 4+

You can operate the various features of your FREECOM 4+ in the following ways:

● Press a button or combination of buttons on the unit.

● Use the Cardo Mobile App on your mobile device (once it is paired with the unit).

● Use automatic voice recognition (by saying a command, for example "Hey Cardo, Radio On").

You can also configure your unit by connecting it to a computer with the supplied USBcable and running the
Cardo Updater while your computer is connected to the Cardo Update website.

2.5 PAIRING YOUR UNIT TO BLUETOOTH DEVICES

Your FREECOM 4+ has two Bluetooth channels for connection to Bluetooth devices such as mobile phones,
GPS devices, and Bluetooth music players with A2DP.

To connect your unit to a Bluetooth device, you must first pair them. Once paired, they automatically recognize
each other whenever they are within range.

If you are pairing more than one device, Cardo recommends that you pair the mobile phone to channel 1,
and the additional device (such as GPS, music player or additional mobile phone) to channel 2.

If you are pairing the unit to more than one mobile phone, the phone paired with channel 1 is the default
phone for outgoing calls.

To pair Bluetooth channel 1 to a mobile phone:

1. Enable Bluetooth on the mobile phone.

2. On the unit in standby mode, press

for 5 seconds.

The LED flashes red and blue.

3. On your mobile phone, search for Bluetooth devices.

4. When your FREECOM 4+ appears in the list of available devices, select it.
If prompted for a PIN or Passkey, enter 0000 (four zeros).

The phone confirms that pairing has succeeded and the LED flashes purple for 2 seconds.

To pair Bluetooth channel 2 to another Bluetooth device:

1. Enable Bluetooth on the device (for example, your mobile phone, GPS device, or music player).

6

2. On the unit in standby mode, press for 5 seconds. The LED flashes red and blue.

3. Tap twice. The LED flashes red and green.

4. If you are pairing a GPS device, roll the control wheel forward.

The LED flashes slower.

5. On the device you are pairing, search for Bluetooth devices.

6. When your FREECOM 4+ appears in the list of available devices, select it.
If prompted for a PIN or Passkey, enter 0000 (four zeros).

The device confirms that pairing has succeeded and the LED flashes purple for 2 seconds.

● If pairing is not completed within 2 minutes, the unit automatically returns to Standby.

● If you have paired two different mobile phones directly to your FREECOM 4+, set one as default for

making calls (see Setting the Default Mobile Phone on page 20).

● Not all Bluetooth mobile phones broadcast Bluetooth Stereo music (A2DP) even if the phone has an

MP3 player function. Consult your mobile phone’s user manual for more information.

● Not all Bluetooth GPS devices allow connection to Bluetooth audio devices. Consult your GPS User

Manual for more information.

To cancel the pairing process:

● Press

for 2 seconds.

The LED stops flashing red and blue/green.

To reset all Bluetooth device pairing:

1. Press

for 5 seconds.

The LED flashes red and blue.

2. Press

4. RIDING WITH OTHERS

4.1 BLUETOOTH INTERCOM

To connect your unit to another unit with a Bluetooth intercom, such as a Cardo Bluetooth unit or other
Bluetooth-enabled devices, you must first pair their channels. Once paired, the units automatically recognize
each other whenever they are in range (line of sight up to 1.2 km / 3,900 ft subject to terrain).

● Pairing a channel replaces any existing paired unit on that channel with the new unit.

AGC and voice control performance vary based on environmental conditions, including riding speed,
helmet type and ambient noise. For improved voice control performance, minimize the wind impact on the
microphone by closing the visor and using the large microphone sponge.

6.1 SETTING THE DEFAULT MOBILE PHONE

If you paired your unit to two mobile phones, you must set one of them as the default phone for outgoing calls.

If you do not set a default phone, the phone that you first paired with your unit is automatically set as the
default phone.

To set the default phone:

● During a mobile call, press

for 5 seconds.

6.2 USING PARALLEL AUDIO STREAMING

With parallel audio streaming, you can hear GPS instructions during a mobile or Bluetooth intercom call, or
while listening to other audio sources, such as music or FM radio.

Parallel audio streaming may not work properly with some iOS devices (i.e., music player or GPS navigator)
due to connected device limitations.

Your FREECOM 4+ sets the various audio sources to either foreground (volume remains the same) or
background (volume reduced) as described in the following table:

If you add an intercom call to a mobile phone call creating a conference call, the volume for both audio

If you make two intercom calls simultaneously creating an intercom conference call, you cannot hear the

In some cases, parallel audio streaming may not work properly due to connected device limitations (music
player or GPS navigator). For more information, see www.cardosystems.com/support/freecom-4-plus/.

Cardo recommends that during a 3-way or 4-way Bluetooth intercom conference call, the rider who is
connected to only one intercom call listens for mobile phone and GPS announcements.

You cannot use music sharing for voice audio with riders during parallel audio streaming.

You can configure parallel audio streaming via the Cardo app.

6.3 AUDIO SOURCE PRIORITIES

If Parallel Audio Streaming is disabled, FREECOM 4+ manages the audio sources you hear through the
speakers according to the following audio source priorities.

When audio priority is set to A2DP (music), the intercom is disabled while listening to music (via A2DP). A

rider calling you by intercom hears a sound indicating you are not available.

Intercom modes all have the same priority, so ongoing intercom calls will not be interrupted by any other
intercom call.

If you paired your unit to two mobile phones (see Setting the Default Mobile Phone on page 20), music will
be shared from the mobile phone through which you last played music.

buying our products only from authorized Cardo dealers.

Your favorite brick-and-mortar store is always your best bet. Unauthorized online resellers and online
auction sites such as eBay are not among Cardo’s authorized dealers, and purchasing our products from
such sites will be at your own risk. Cardo strives to provide quality products and exceptional customer
service. We select dealers who share that vision. Buying grey market items from unauthorized online
dealers is counterproductive and also adversely affects unsuspecting online consumers who may be
purchasing used, counterfeit or defective products or devices whose warranties are void. Protect your
investment by purchasing genuine Cardo products only from authorized dealers.
