mode. You will hear a voice prompt saying “Last number redial”.
10.3 Enabling/Disabling Voice Activated Phone
Answering, VOX Phone (Factory Default: Enabled)
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 for an incoming call, you can answer the phone by saying
“Hello” or any other word loudly. This is enabled from the factory but
you can disable this. If this mode is disabled, the only way to answer
an incoming call is to tap the Phone Button.
10.1 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 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.
10.2 Mobile Phone Call Making and Answering
1. When you have an incoming call, simply tap the Jog Dial or the
Phone Button to answer the call.
2. You can also answer the incoming call by loudly speaking any word
of your choice if 

is not pressed within 10 seconds, it remains unchanged and goes
back to stand-by.
10.4 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.

10.6 Intercom Failure
When you try to start an intercom conversation with an intercom friend
who is already having an intercom conversation with another intercom
friend or 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.
10.7 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. You will hear high tone
double beeps until the intercom is reestablished. If you don’t want to
make a reconnection, tap the Jog Dial to stop the attempt.
10.8 Stereo Music
You can listen to stereo music by Bluetooth wireless stereo. The
Bluetooth audio device must be paired with the SMH5 by following the
Bluetooth Stereo Device Pairing instructions described in the previous
chapter. The SMH5 supports the Audio/Video Remote Control Profile
(AVRCP), so if your Bluetooth audio device also supports the AVRCP,
a. To answer the phone call and stop the intercom conversation,
tap the Jog Dial or the Phone Button. When you hang up the
phone call, the intercom will automatically be recovered.
b. To reject the phone call and stay on the intercom conversation,
press the Jog Dial 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.
