9. USING THE SMH3
9.1 Volume Adjustment
You can easily adjust the volume by tapping the (+) Button or the (-) Button. You will hear a beep when the volume
reaches maximum or minimum level. The volume is set and maintained independently at different levels for each audio
source even when you turn off and on the headset. For example, once you set the volume for mobile phone handsfree, it
will not change even if you adjust the volume when you hear Bluetooth MP3 music. So you can always maintain the
preferred optimum volume level for each audio source.
9.2 Mobile Phone Call Making and Answering
1. When you have an incoming call, simply tap the (+) Button to answer the call.
2. You can also answer the incoming call by loudly speaking any word of your choice if Voice Activated Phone
Answering, VOX phone is enabled. (Refer to the next section for details.)
3. To end a call, press the (+) Button for 2 seconds until you hear a mid-tone single beep, or wait for the called person
to end the call.
4. To reject a call, press the (+) Button for 2 seconds until you hear a beep while the phone is ringing.
5. There are several ways to make a phone call:
- Enter numbers on your mobile phone keypad and make a call. Then the call is automatically transferred to the headset.
- Press the (+) Button for 3 seconds in stand-by mode until you hear a high tone single beep 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 instruction.
- To redial the last number, press the (-) Button for 3 seconds in stand-by mode until you hear a high tone single beep.
You will hear a voice prompt saying “Last number redial”.
Note:
1. If you are using multipoint mobile phone connection and you have an incoming call from the second phone during the
call of the first phone, then you may still receive the call from second phone. In this case, the call from the first phone is
on waiting mode. If you end a call, then it will automatically guide you to the first phone call.
2. If you are using multipoint connection of mobile phone and GPS, you may not listen to the GPS voice instruction during
the phone call.
9.3 Intercom Conversation
1. You can start an intercom conversation with any of intercom friends by pressing the (-) Button for 1 second.

2. To terminate an intercom conversation, press the (-) Button for 1 second again.
[picture 11-2]
9.4 Intercom and Mobile Phone Call
1. When you have an incoming mobile phone call during an intercom conversation, you will hear a ring tone. You can
choose whether to 1) answer the mobile phone call and stop the intercom conversation, or 2) reject the phone call and
stay on the intercom conversation.
● To answer the phone call and stop the intercom conversation, tap the (+) Button. When you hang up the phone
call, the intercom will automatically be recovered.
● To reject the phone call and stay on the intercom conversation, press the (+) Button for 2 seconds until you hear a
beep.
Unlike other motorcycle Bluetooth headsets, this prevents a user from being dropped out of an intercom conversation
by an incoming mobile call.
2. When you have an incoming intercom call during a mobile phone call, you will hear 4 high tone beeps, alerting you
that there is an incoming intercom call. You will also hear a voice prompt saying “Intercom requested”. In this case,
the intercom call does not override the mobile phone call because intercom has lower priority than mobile call. You
have to hang up the mobile phone call to make or receive an intercom call.
9.5 Intercom Failure
When you try to start an intercom conversation with an intercom friend who is already having a mobile phone call with
another person, you will hear a low tone double beep signifying a busy signal. You will also hear a voice prompt saying
“Intercom failed, try again later”. In this case, you have to try again later. On the other hand, the intercom friend will
hear 4 high tone beeps alerting them that there is an incoming intercom call.
9.6 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 SMH3 automatically tries to reconnect the intercom every 8 seconds.
You will hear high tone double beeps until the intercom is reestablished. If you don’t want to make a reconnection, tap the
(-) Button to stop the attempt.
9.7 Stereo Music
You can listen to stereo music by Bluetooth wireless stereo. The Bluetooth audio device must be paired with the SMH3 by
following the Bluetooth Stereo Device Pairing instructions described in the previous chapter. The SMH3 supports the
Audio/Video Remote Control Profile (AVRCP), so if your Bluetooth audio device also supports the AVRCP, you can use
![](/img.php?id=2378420&img=bg12.png)
| SMH3
18
the SMH3 to remotely control music playback. So, You not only can adjust the volume but also use the functions such as
play, pause, next track and previous track.
● To adjust the volume, tap the (+) Button or the (-) Button..
[picture 11-3]
● To play or pause music, press and hold the (+) Button for 1 second until you hear a double beep.
[picture 11-4]
● To track forward or track back, press and hold the (+) Button or the (-) Button for 2 seconds until you hear a
double beep.
[picture 11-5]
9.8 Function Priority
The SMH3 operates in the following order of priority:
(Highest) Mobile Phone,
Intercom, and
(Lowest) Bluetooth Stereo Music
A lower priority function is always interrupted by a higher priority function. For example, stereo music is interrupted by
intercom call, and intercom conversation is interrupted by incoming mobile phone call.
9.9 Fault Reset
When the SMH3 is not working properly or is in faulty status for any reason, you may reset by pushing the pin-hole reset
button on the left speaker unit. Insert a paper clip into the reset pin-hole and press the reset button for a second with light
pressure. The SMH3 will be switched off after which time, you have to turn the system back on and try again. However,
this will not restore the headset to factory default settings.
