1. Introduction
Bluetooth profile K-6 gives an implementation guideline for Bluetooth headset
application, which includes two functions: Bluetooth headset and Bluetooth
audio gateway. Generally headset profile will be implemented in headset, and
audio gateway will be implemented in cellular phone, PBX or other
communication devices. Windigo systems has developed a fully Bluetooth
V1.1 compliant headset module.
This manual will explain the basic headset operation instruction to our
customers.
2. A glimpse at the headset
Figure 1 illustrates the reference headset and cellular phone.

The three buttons are used to initialize various operations, such as activating
the headset, turning off the headset, pairing, connecting, etc.
Audio connections are used to connect an external microphone and speaker.
Windigo Bluetooth Headset must be paired with an audio gateway before it is
fully functional. Please refer to the audio gateway user manual on how to
initialize and operate the audio gateway and its various functions.
3. Getting start
Step 1:
Be sure the headset battery is fully charged before the first time use.
(Charging time is about 2 hours)
Step 2:
Enter into pairing (discoverable and connectable) mode
During headset transportation, headset is on idle (deep sleep) mode to
conserve battery power. While in this idle mode, both blue and amber LEDs
are off. To enable the pairing mode, press and hold the talk button until blue
and amber LED flash alternatively, and a PAIR tone will be heard. This press
and hold time is about 5 seconds. Please be noted that before blue and
amber LED flash alternatively, either blue or amber LED will flash shortly
depends on the battery status, and an ON tone will be heard. So in order to
enter into pairing mode correctly, please still hold the talk button. After the
PAIR tone is heard, and blue and amber LED flash alternatively, then release
the button.
Note:
1. Default headset name is BTHS03, and pin code is 0000
2. Pairing feature is used to establish the relationship between headset and
audio gateway. Any given headset can only talk with the paired audio
gateway after a successful pairing session.
3. Pairing mode can be cancelled by pressing and holding the talk button for
about 3 seconds, until both amber LED and blue LED are off, and the OFF
tone is heard. Then the headset is put into idle mode again.
4. Follow the instruction for specific audio gateway to perform the pairing. If
the headset has been paired with audio gateway successfully, the headset
will enter into standby (connectable only) mode. During this mode, blue
LED will flash at 1-second interval if battery is full, and amber LED is off.
Otherwise, if battery is low, then amber LED will flash at 1-second interval
and blue LED will be off.
Step 3:
Now the headset is ready to use. The headset will ring whenever there is an
incoming call.

Step 4:
Answering the incoming call.
When the headset is ringing, user can pick up the call by pressing the talk
button once shortly.
Note:
Make sure the cellular phone has been configured correctly so an
incoming call is transferred to the headset via Bluetooth link.
Step 5:
Initiate connection to audio gateway
Normally the headset will stay in standby mode, if user wants to initiate a
connection to the audio gateway, for example, voice dial with a suitable
cellular phone, user can press the talk button once. While in this mode, the
blue LED (or amber LED if battery low) will flash quickly for twice, then after 1
second, blue LED (or amber LED if battery low) will flash twice quickly again.
In other words, the LED will flash quickly twice every 1 second. Once the
connection between headset and audio gateway is established, the blue LED
(or amber LED if battery low) will flash four times quickly after 3 second.
Step 6:
Adjusting the volume
Once the audio connection is established, User can adjust the volume by
pressing volume button shortly to adjust the volume to louder or softer.
Step 7:
Mute/un-mute the microphone during talking.
User can mute/un-mute the microphone temporally by depressing either
volume button for about 3 seconds. If the microphone is muted, to un-mute
the microphone, user can depress either volume button for 3 seconds.
4. Summary of the LED display

Headset is in idle mode
If blue LED is working, means battery is fully
If amber LED is working, means battery runs low
LED flashes at 1-seconds interval
Headset is in standby (connectable) mode
LED flashes twice quickly at 1-seconds interval
Headset is trying to make an audio connection to phone. This most
probably will happen when user wants to make a voice dial.
LED flashes four times quickly every 1-second interval
