Sena SMH5 Support

Frequently Asked Questions


The SMH5 operates in the following order of priority:

Mobile Phone (Highest)
Music sharing by Bluetooth stereo music
Bluetooth Stereo Music (Lowest)

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.

To power On press the Jog Dial and the Phone Button at the same time for about 1 second to power on. The blue LED turns on and you will hear ascending beeps.

To power Off just short press the Jog Dial and the Phone Button simultaneously, you don’t need to press and hold for a few seconds. The red LED turns on for a while until it turns off completely and you will hear descending beeps.

To charge the SMH5, use the USB Power & Data Cable included in the package by plugging into computer’s USB port or USB wall charger. USB wall charger is not included in the package, but you can use any USB wall charger in the market.

The Charging LED beside the charging port turns on red while charging, and turns to blue when the headset is fully charged. It takes about 2.5 hours to be fully charged.

You can check the battery level in two different ways when the headset is powering on.

LED indicator:

When the headset is powering on, the red LED flashes rapidly indicating the batter y level.

4 flashes = High, 70~100%
3 flashes = Medium, 30~70%
2 flashes = Low, 0~30%

Voice Prompt Indicator:

When you power on the headset, keep pressing the Jog Dial and Phone Button simultaneously for about 3 seconds until you hear three high tone beeps. Then you will hear a voice prompt indicating the battery level. However, if you release the buttons as soon as the headset turns on, you will not hear the voice prompt for the battery level.

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.

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, you can use the SMH5 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, 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.

You can start sharing music with an intercom friend using Bluetooth stereo music during a two-way intercom conversation. When you terminate music sharing, you can go back to the intercom conversation. To start or terminate sharing music, press and hold the Jog Dial for 1 second during an intercom conversation until you hear a double beep and you and your intercom friend will listen to or terminate sharing music. To track forward or track back, rotate while pressing down the Jog Dial clockwise or counter clockwise.


1. Both you and your intercom friend can remotely control music playback during music sharing such as track forward and track back.

2. When you have an incoming call, make a phone call, or hear the turn-by-turn voice instruction of GPS during music sharing, the function will be paused.

3. In order to share music, make sure that you update both headsets with the firmware that has the music sharing feature, and enable the EDR setting in the Sena Device Manager.


The SMH5 can be paired with up to three other headsets for Bluetooth Intercom conversation.

3. Simply tap the Jog Dial of any one of the two headsets A or B (It doesn’t matter that you choose A or B) and wait until the LEDs of both headsets turn to blue and intercom connection is automatically established. The two SMH5 headsets A and B are paired with each other for intercom conversation. If the pairing process is not completed within one minute, the SMH5 will return to stand-by mode.


When the SMH5 is not working properly or is in faulty status for any reason, you may reset by pushing the pin-hole reset button at the back of the headset main unit. Insert a paper clip into the reset pinhole and press the reset button for a second with light pressure. The SMH5 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.
