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 SMH10 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.
