| SMH5-FM(SMH5) USING THE SMH5-FM(SMH5) Volume Adjustment You can easily adjust the volume by rotating the Jog Dial. You will hear a beep when the volume reaches maximum or minimum level. The volume is set and maintained separately at different levels for each function even when you turn off and on the headset. For example, once you set the mobile phone conversation volume, it is not changed even if you raise the volume when you hear Bluetooth MP3 music. So you can always maintain preferred optimum volume level for each function. Mobile Phone Call Making and Answering 1. When you have an incoming call, simply tap the Phone Button to answer the call. 2. You can also answer the incoming call by loudly speaking any word of your choice if the Voice Activated Phone Answering Function of the SMH5-FM(SMH5) is enabled. (Refer to the next section for detail) 3. To reject a call, tap the Jog Dial while the phone is ringing. 4. To transfer a call between the mobile phone and the headset, tap the Jog Dial during the phone conversation. You will hear a short/long beep when the call is transferred to the phone/headset. 5. There are several ways to make a phone call:

- Enter number on your mobile phone keypad and tap the Phone Button. The call is automatically transferred to the headset.

- Tap the Phone Button in stand-by mode to activate the voice dialing of your mobile phone. For this, the voice dialing feature must be available on the mobile phone. Refer to your mobile phone manual for further instructions.

- To redial the last number, double tap the Phone Button in stand-by mode. 9

| SMH5-FM(SMH5) Enabling/Disabling Voice Activated Phone Answering (Factory Default: Disabled) If this feature is enabled, you can answer incoming calls by simply saying a word loudly enough. For example, when you hear a series of beeps by an incoming call, you can answer the phone by saying Hello or any other word loudly. The factory default setting is disabled. You can enable or disable this mode. If this mode is disabled, the only way to answer an incoming call is to tap the Phone Button. 1. Press and hold the Phone Button for 8 seconds until the red LED is rapidly flashing. When you do this, after first 5 seconds you press the button, you will see the headset enters into the Mobile Phone Pairing sequence, but you have to keep pressing the button for another 3 seconds until the red LED flashes rapidly. 2. To enable, tap the Phone Button, then the LED shows solid blue for 2 seconds and you will hear double beeps. 3. To disable, tap the Jog Dial, then the LED shows solid red for 2 seconds and you will hear a single beep. Intercom Conversation 1. You can start an intercom conversation with any of Intercom Friends by tapping the Jog Dial: single tapping to intercom with the First Intercom Friend, double tapping with the Second Intercom Friend, and triple tapping with the Third Intercom Friend. 2. To terminate an intercom conversation, single tap the Jog Dial. Any intercom connection with any Intercom Friend will be terminated by a single tapping. 3. When you have an incoming phone call during intercom conversation, you can choose whether to pick up the call or not after you hear the ring tone. 4. When you have an incoming intercom call during a mobile phone conversation, you will hear high tone 4 beeps. You have to hang up the mobile phone to make an intercom connection. Enabling/Disabling Voice Activated Intercom (Factory Default: Disabled) If this feature is enabled, you can initiate an intercom conversation with the last connected Intercom Friend by speaking any word loudly enough.The most effortless way to trigger intercom VOX is to blow into the microphone as if blowing dust off the microphone.If you start an intercom conversation by VOX,the intercom terminates automatically whenyou and your Intercom Friend remain silent for 20 seconds. However, if you manually start an intercom conversation by tapping the Jog Dial, you have to terminate the intercom conversation manually by tapping the Jog Dial again. If this feature is disabled, the only way to initiate and terminate an intercom conversation is to tap the Jog Dial. 10 1. Press and hold the Jog Dial for 8 seconds until the red LED turns on solidly. When you do this, after first 5 seconds you press the Jog Dial, you will see the headset enters into the Intercom Pairing sequence, but you have to keep pressing the Jog Dial for another 3 seconds until the LED turns to solid red. 4. To enable, tap the Jog Dial, then the blue LED flashes for 2 seconds and you will hear double beeps. 5.

| SMH5-FM(SMH5) Tip:

The Jog Dial is for any kind of Intercom related function, and the Phone Button is for any functions of mobile phone. With this reason, as far as intercom function is concerned, the Jog Dial is used for a positive manner of action such as enabling, and the Phone Button is for a negative manner of action such as disabling. Vice versa for the mobile phone functions. Intercom Failure When you try to start an intercom conversation with an Intercom Fried who is already having a 3-way conference intercom with other persons or a mobile phone call, you will hear a low tone double beep signifying a busy signal. In this case, you have to try again later. Intercom Reconnection If your Intercom Friend goes out of range while having an intercom conversation, you may hear static noise and eventually the intercom will be disconnected. In this case, the SMH5 automatically tries to reconnect the intercom every 8 seconds and you will hear high tone double beeps until the intercom is reestablished. If you dont want to make a reconnection, tap the Jog Dial to stop the attempt. Stereo Music 1. By Bluetooth Wireless Stereo The Bluetooth audio device must be paired with the SMH5-FM(SMH5) by following the Bluetooth Audio Device Pairing instructions described in the previous chapter. The SMH5-FM(SMH5) supports the Audio/Video Remote Control Profile (AVRCP), so if your Bluetooth audio device also supports the AVRCP, you can use the SMH5-

FM(SMH5)to remotely control music playback. So, you may not only adjust the volume but also use the functions such as play, pause, next track and previous track. To adjust the volume, rotate the Jog Dial. To play or pause music, press and hold the Jog Dial for 1 second until you hear a double beep. To track forward or track back, rotate while pressing the Jog Dial clockwise or counter clockwise. 12
