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°C and
25°C (59°F and 77°F). 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 Sena Expand 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, speaker-microphone clamp unit, or power
charger.
