FUNCTION
With the hands-free cellular phone system, the
cellular phone and hands-free module communicate
with each other by using Bluetooth™.

TROUBLE JUDGMENT CONDITIONS
When the cellular phone cannot be recognized or the
communication cannot be established, the cellular
phone or hands-free module may be defective.

｠

Malfunction of the cellular phone

｠

Malfunction of the hands-free module

DIAGNOSIS

STEP 1. Check the cellular phone.
Check that the cellular phone can be used normally
as a unit.

Q:Is it possible to use the cellular phone

normally?

YES:

Go to Step 2.

NO:

Repair or replace the cellular phone.

STEP 2. Check the position of cellular phone.
Check that the function becomes normal when the
cellular phone is moved closer to the hands-free
module.

Q:Does the function become normal when the

cellular phone is moved closer to the hands-

free module?

YES:

No action is necessary and testing is

complete.

NO:

Go to Step 3.

STEP 3. Check the registration method of cellular
phone.
By referring to the operation manuals, check that the
cellular phone was registered to the hands-free
module by following the normal procedure.

Q:Was the cellular phone registered by following

the normal procedure?

YES:

Check the trouble symptom, and finish when

it is normal. When the abnormality is present,
go to Step 4.

NO:

Register a cellular phone according to a

regular procedure.

STEP 4. Temporarily replace the cellular phone,
and check the trouble symptom.
Temporarily register a separate Bluetooth™-
supported cellular phone, and check that the hands-
free cellular phone system operates normally.

Q:Is the normal conversation possible with the

hands-free system?

YES:

Ask the customer to have the cellular

phone repaired or replaced. Then, delete the
temporarily registered cellular phone. Once the

customer prepares the normally-working cellular
phone, register the cellular phone to the hands-
free module.

NO:

Replace the hands-free module.

Inspection Procedure 6: Check the hands-free module power supply circuit.
