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 SPH10H 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.
