4.4 Bluetooth GPS Navigation Pairing
You can listen to voice instruction from Bluetooth GPS navigation. Some GPS systems use mobile phone profile (HFP,
Hands-Free Profile) and others use stereo music profile (A2DP, Advanced Audio Distribution Profile). Most motorcycle
specific GPS systems use mobile phone profile for turn-by-turn voice instruction. You can simultaneously use a mobile
phone and a GPS which uses mobile phone profile by one of the following procedures.
4.4.1 Multipoint GPS Pairing

| EXPAND
9
If you use GPS only for turn-by-turn voice instructions, not for Bluetooth stereo music streaming, multipoint pairing is

6. If the pairing process is not completed within three minutes, the EXPAND will return to stand-by mode.
4.4.2 GPS Pairing as Mobile Phone
If GPS is not only used for turn-by-turn voice instructions but also is your preferred Bluetooth stereo music source, you
can pair the GPS to the EXPAND by following the simple procedures in “7.1 Mobile Phone Pairing”. When you do this, the
EXPAND thinks the GPS is a mobile phone. But EXPAND can directly pair an additional mobile phone.
Note:
You have to use a motorcycle specific GPS which transmits turn-by-turn voice instruction to the headset by Bluetooth.
Most automotive GPS systems don’t have this feature.

refer to the SR10 user's guide for details.
5. PAIRING WITH SELECTIVE PROFILE: HFP OR A2DP STEREO
If you have a MP3 stereo music phone such as a smartphone, sometimes you may need to selectively use the EXPAND
for A2DP stereo music only or for mobile phone handsfree only. This instruction is for advanced users who want to pair
the EXPAND to their smartphones only with one selective profile: A2DP stereo for music or HFP for phone call.
If you have previously paired a mobile phone to the EXPAND, you must clear the previous pairing list on both devices; the
mobile phone and EXPAND. To clear the pairing list on EXPAND, please do a factory reset or follow the pairing list

BATTERY INFORMATION
The EXPAND has an internal, non-removable external, rechargeable battery. Do not attempt to remove the battery from
the device as you may damage the device. The battery can be charged and discharged hundreds of times, but it will
eventually wear out. Recharge the battery only with Sena approved chargers designated for this device. Use of an
unapproved charger may present a risk of fire, explosion, leakage, or other hazard.
Always try to keep the battery between 15℃and 25℃(59℉and 77℉). Extreme temperatures reduce the capacity and
lifetime of the battery. A device with a hot or cold battery may not work temporarily. Battery performance is particularly
limited in temperatures well below freezing.
Do not dispose of batteries in a fire as they may explode. Batteries may also explode if damaged. Never use any charger
that is damaged. Operating times are estimates only and depend on the devices used together, features used, battery
age and condition, temperatures to which battery is exposed, and many other factors.
MAINTENANCE AND CARE
The SHM10R should be treated with care and the following suggestions will help you protect your warranty coverage.
1. Do not use or store the device in dusty, dirty areas. Its moving parts and electronic components can be damaged.
2. Do not store the device in hot areas. High temperatures can shorten the life of electronic devices, damage batteries,
and wrap or melt certain plastics.
3. Do not store the device in cold areas. When the device returns to its normal temperature, moisture can form inside
the device and damage electronic circuit boards.
4. Do not attempt to open the EXPAND
5. Do not drop or knock the device. Rough handling can break internal circuit boards and fine mechanics.
6. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the device.
7. Do not paint the device. Paint can clog the moving parts and prevent proper operation.
These suggestions apply equally to the headset main unit, speaker-microphone clamp unit, or power charger.
