Using Bluetooth version 1.2, it provides a fast connection speed and excellent sound quality. The ADB-2381 uses one AAA battery which delivers long standby and talking times. The battery is easily replaced and there's no need for recharging. The ADB-2381 supports both the headset and handsfree profiles so it ® can be paired with any other Bluetooth enabled devices with these profiles, such as mobile phones or computers, thus freeing your hands for other tasks. The controls are easy to operate and can be activated with one hand while the headset is in use. Operation Requirement ® The ADB-2381 can connect with any Bluetooth device which supports the headset or handsfree profiles. 2 Contents This package contains the following: 1. Headset 2. One AAA alkaline battery 3. Ear Hook 4. Quick Guide 5. User's Guide The accessories may be subject to change for the sake of product improvement. Changes may be made without prior notice. 4 Operating Instructions: Replacing the battery 1. If the battery runs low in your headset, the bottom (red) LED will flash intermittently, and there will be a slight beep tone from the speaker indicating that the voltage is running low. 2. In such a case, the battery should be replaced. 3. Simply open the battery door at the top of the headset to access the battery compartment. Remove the old battery and replace with a fresh alkaline AAA. 4. Insure that the polarity of the battery matches the markings on the case. 3 Features 1. Talk Button: Controls multiple headset functions 2. Battery door: For accessing and changing the battery 3. Ear Hook: Can be rotated for right or left ear 4. LED indicator: Provides visual cue of headset status 5. Microphone 6. Speaker 7. Volume Up 8. Volume Down 5 Operating Instructions: Note: A fresh headset battery will yield approximately 15 hrs. of talking time and more than two weeks standby. Replacing the battery 6 Operating Instructions: Note: Avoid touching the headset battery cover when in use, which may accidently open the cover door. Changing for wear on the left ear: 0 1) Open the ear hook (90 from the headset); 0 2) Rotate the ear hook by 180; 3) Press the ear hook to the speaker of the headset; 8 Operating Instructions: 7 Operating Instructions: Wearing the headset When packaged, the headset is originally set-up to be worn on the right ear. 1. Open the ear hook approximately 45° away from the unit. 2. Place the ear hook over the ear. 3. Close the headset flat against the ear hook, insuring good auditory reception. 4. Point the microphone towards your mouth. 10 Operating Instructions: 6 seconds 9 Operating Instructions: 2 seconds Turning the headset on: 1. Press and hold the Talk button for about 6 seconds, until the green LED flashes and there is a brief tone from the speaker. 2. The headset is now on and in Standby mode. Note: If the battery is low, the red LED will flash. Turning the headset off: 1. Press and hold the Talk button for approx. 2 seconds. The red LED will flash and there will be a brief tone from the speaker. The unit will then power off. Pairing ® 1) Put the Bluetooth device within 30 cm. of the headset. 2) Make sure the headset is off. Keep pressing the Talk button for about 6 seconds until the red and green LED indicators flash alternately. The earpiece is now in pairing mode. 3) Perform a device discovery from your phone. (For details on device discovery for your phone, refer to the phone's user's guide.) When the scan is complete, the phone displays the devices found. Before you use the headset, you must pair it with your ® mobile phone or other Bluetooth device. “Pairing”creates a ® secure link between Bluetooth devices, and allows the phone or other device to remember the headset's unique ID. When the headset is paired to the mobile phone, it will automatically connect to the mobile phone. Note: 12 Operating Instructions: Answering a call: When the headset rings or the audio signal is heard, press the Talk button briefly. Rejecting a call: To refuse an incoming call, press and hold the Talk button for approximately 2 seconds and the call will be refused. Ending a call: Same as the steps for answering a call. Note: If your mobile phone is Sony Ericsson, please see the table in Section 14 for more information. 11 Operating Instructions: 4) Select the ADB-2381 from the discovered devices list and confirm following the on-screen prompts. 5) When prompted by the phone, enter the password “1234” and confirm the pairing with the phone. Pairing is successful when the red LED stops flashing. The device's ID is now stored in the phone's memory. They can connect automatically when you use them afterward. 13 Operating Instructions: Adjusting the volume: Use the Volume Up or Volume Down buttons to increase or decrease the volume. At each increment, there will be a slight tone from the speaker, until it reaches its maximum or minimum level. Note: It is strongly recommended to adjust the volume slowly and in increments, to avoid damage to sensitive hearing.

Hopping Information 1 Hopping Range Hereby we declare that the maximum frequency of this device is: 2402-2480MHz. This is according the Bluetooth Core Specification V1.2 (+ critical errata) for devices which will be operated in the USA. This was checked during the Bluetooth Qualification tests (Test Case: TRM/CA/04-E). Other frequency ranges (e.g. for Spain, France, Japan) which are allowed according the Core Specification are not supported by this device. 2 Hopping Sequence Example of a 79 hopping sequence in data mode: 33,04,21,44,23,42,53,46,55,48,40,59,72,29,76,31,08,73, 07,75,09,45,60,39,58,13,47,11,77,52,35,50,65,54,67,56, 69,62,71,64, 37,25,27,66,57,70,74,61,78,63,10,41,05,43, 15,44,64,68,02,70,06,01,51,03,55,05,03,66,53,49,36,47, 3 Receiver input bandwidth The input bandwidth of the receiver is 1MHz. In every connection one Bluetooth device is the master and the other one is the slave. The master determines the hopping sequence. The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing according to the packet type of the connection. Also the slave of the connection will use these settings. Repeating of a packer has no influence on the hopping sequence. The hopping sequence generated by the master of the connection will be followed in any case. That means a repeated packet will not be send on the same frequency, it is send on the next frequency of the hopping sequence.
