Operation is subject to the following two conditions:(1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. Shielded interface cables must be used in order to comply with emission limits. Changes or modifications not expressly approved by the party responsible for compliance could void the user‘s authority to operate the equipment.

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. Figure 1. Windigo Bluetooth Headset Reference Design The headset module includes an amber LED, a blue LED, three buttons, and embedded audio connections and charging contact, these elements are illustrated in figure 2. Figure 2. Key elements on Windigo Bluetooth Headset Both amber LED and blue LED are used to indicate various operation status for the headset, such as pairing, connecting, talking...etc. Talk Button Amber LED Blue LED Volume Up Volume Down Fig. 1.a PBTHSTA2C2M – Top View Fig1.b PBTHSTA2C2M- Bottom View Confidential Page 4 5/8/2003 2210 O’Toole Ave. #200, San Jose, Ca. 95131 Tel: 408-576-1770 Fax: 408-576-1790 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.

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 Blu…
