How to Troubleshoot the HandsFreeLink System (Continued)

Incoming Calls

Call the Acura's dedicated call center at 888-528-7876 after you have duplicated the problem.

If a client complains that they cannot receive incoming calls through the HFL system, see if the call is routing to the cell phone instead of the HFL system. An easy way to know if the call is routed to the cell phone is when the client says, "I can't hear the caller, but they can hear me."

1. Make sure the Bluetooth feature is turned on in the cell phone.

2. Make sure the cell phone is paired to the HFL system and linked.

3. Make sure the answer settings in the cell phone are set to multi-key or any-key answer. If the cell phone is set to flip-open to answer, recommend changing the setting to Any Key or leaving the cell phone flipped open when using the HFL system.

4. Make sure the Auto Answer feature is turned off in the cell phone.

5. Do a soft reset to the cell phone.

6. Make sure the battery is fully charged and there is adequate signal strength.

7. Ask the client if they have set specific ring tones or ringer IDs to specific contacts. If they have, recommend returning them to a standard ring tone for all calls.

8. Make sure the client is pressing the PICK-UP button (A) or the HFL TALK button (B) and not the HANG-UP button (C), the HFL BACK button (D), the TALK button (E), or the BACK button (F).






Outgoing Calls

Call the Acura's dedicated call center at 888-528-7876 after you have duplicated the problem.

If a client says that they cannot place a call using the HFL system, ask if the call was initiated through the HFL system or the cell phone itself.

If the call is placed by the HFL system:

1. Make sure the Bluetooth feature is turned on in the cell phone.

2. Make sure the cell phone is paired to the HFL system and linked.

3. Make sure the client is pressing the TALK button (A) or the HFL TALK button (B) before each command and going through the calling process correctly.





4. Make sure the client is pressing the PICK-UP button (C) or the HFL TALK button and not the HANG-UP button (D), the HFL BACK button (E), the TALK button, or the BACK button (F).

5. Check if the cell phone has an Authorized Connections or Trusted option.

6. Do a soft reset to the cell phone.

If the call is placed by the cell phone:

- With navigation system; The call will remain on the handset until you transfer it over to the HFL system. To continue the call on the HFL system, you must use the Transfer command by selecting "Transfer." The client can now continue the call using the HFL system.
- Without navigation system; By default calls made from the handset will transfer to the HFL system. If Auto-transfer is turned "off " calls will remain on handset. To continue or the HFL system, press the HFL TALK button and say "Transfer."

Clearing the HFL System

With Navigation

The commands for deleting a cell phone can either be selected using the interface dial or by using the voice recognition system (use the TALK and the BACK buttons).

NOTE: The entire HFL system cannot be deleted at once. You must delete one cell phone at a time.

1. Turn the ignition switch to ACCESSORY (I).

2. Press the INFO/PHONE button, and turn the interface dial to select Cellular Phone, then press ENTER.

3. Move the interface dial down to select Phone Setup.

4. Select Edit User, and press ENTER.

5. Select Delete, then select the phone you want to delete from the list. Press ENTER to select the phone, then press ENTER again to confirm.

6. Repeat steps 4-5 for each cell phone you want to delete.

Without Navigation

NOTE:

- This operation clears the HFL system of all passcode(s), any paired cell phones, and all names in the HFL phonebook.
- Clearing the HFL system is recommend before selling the vehicle.
- If the system is locked and the pass code is lost or forgotten, see the symptom troubleshooting.

1. Press and release the HFL TALK button. After the beep, say "System setup clear" and the HFL system responds, "This process will clear all paired phones, clear all entries in the phonebook, clear the security passcode and restore all defaults in the system setup. Is this what you would like to do?."

2. Press and release the HFL TALK button. After the beep, say "Yes" and the HFL system responds, "Preparing to clear the system, which may take up to 2 minutes to complete."

3. Press and release the HFL TALK button. After the beep, say "Continue" to proceed, or say "Go back" or "Cancel."

4. If you said "Continue" the HFL responds, "Please wait until the system is cleared". After a short period of time (up to two minutes) the HFL responds, "The system has been cleared."

Self-Diagnostic Function

NOTE: This procedure should be used only if HDS is unavailable.

To run the self-diagnostic function, do the following:

1. Turn the ignition switch to ON (II).

2. Press and hold the HANG-UP button (A) or the HFL BACK button (B) for more than 5 seconds.





3. When the HandsFreeLink system enters the self-diagnostic function, the following will occur.

- If the system has not completed testing for DTCs, the HandsFreeLink system says "The hands free system test is in progress."
- If there is no DTC, the HandsFreeLink system says "The hands free system is OK."
- If there is any DTC, the HandsFreeLink system says "The hands free system needs to be serviced."

NOTE:

- The self-diagnostic function can only be initiated while the HFL is in its idle state.
- The self-diagnostic function starts after you press and hold the HANG-UP button or the HFL BACK button for 5 seconds, and ends if the HandsFreeLink control unit returns to its idle state.

Glossary of Terms

Auto Answer

This cell phone setting forces incoming calls to automatically be answered by the handset. Disable this feature on the cell phone when using the HFL system, as it may interfere with the HFL system answering incoming calls. Set the cell phone setting to:

- Send Only
- Any Key
- Multi-Key answer

Answer Options

These cell phone settings allow you to select how you would like to answer an incoming call on the handset. The answer option in the cell phone can affect inbound calls on the HFL system.

Authorized Connection

This cell phone setting allows the cell phone to connect automatically with the HFL system without prompting the client for permission to connect. In some instances, it can affect the ability of the cell phone to properly route sound to the HFL system.

Bluetooth Power

This cell phone function enables or disables the Bluetooth application. When using a hands-free device such as HFL, the Bluetooth application needs to be enabled.

Discovery Mode

You need to have the cell phone in Discovery Mode to allow other devices with Bluetooth capabilities (such as the HFL system) to find the cell phone during the pairing process.

HFL Button

- TALK button (A) or the HFL TALK button (B): This button activates the voice control system and is used for all voice commends. Press and release it, wait for a beep, and give a voice command.
- BACK button (C) or the HFL BACK button (D): This button has the same function as the CANCEL button. When you press and release it, the current voice command is canceled and the display returns to the previous screen.
- PICK-UP button (E) or the HFL TALK button: This button is used to answer incoming calls or to make outgoing calls. You can also go directly to the Cellular Phone screen by pressing this button.
- HANG-UP button (F) or the HFL BACK button: This button is used to end a call.





Hard Reset (cellular phone)

Hard resets clear the saved settings in the cell phone and restores it to the factory defaults. A hard reset should be done only as a last resort (see the cell phone owner's manual for more information).

Linking

This is when your paired cell phone is actively ready to use the HFL system. You can pair up to six cell phones to the HFL system, but only one cell phone can be linked at a time. If two paired cell phones are in the vehicle, only the cell phone that is linked can use the HFL system and functions. The second cell phone must be used as a normal handset.

Pairing

A description for linking two Bluetooth devices together. In this case, you are linking a cell phone with the HFL system. After the pairing process is complete, the devices are able to recognize each other and communicate wirelessly via Bluetooth.

Soft Reset (cellular phone)

This helps to restore the basic functions of the cell phone. To do a soft reset, turn the cell phone power off, remove and reinsert the cell phone battery, then turn the cell phone back on. See the cell phone user manual for more information.

Software Version

This refers to the software version loaded in the cell phone. The software version that was tested and determined to be compatible with the HFL system may be listed on the HFL website. Not all software versions are compatible with the HFL system.
