BATTERY INFORMATION
The product has an internal, non-removable, 
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 Product 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 Product.
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, earpads, or power charger.
