Donotserviceorperformmaintenanceonthedevicewhilethedeviceisinuse.Makesuretoshut
thedevicedownandunplugallcablesbeforestartingandserviceormaintenanceworkonthe
device.
2.1 PowerSupplyandBatteries
TheMD‐100devicecontainstworechargeablebatteries.Allrechargeable
batteriesdegradeover
time.Thus,thepossibleusagetimesfortheMD‐100afterafullchargecanbecomeshorterover
timethanwhenthedevicewasnew.
TheMD‐100deviceusesaLi‐ionPolymerbattery.
Ifyouareinahotenvironment,beawarethatitcan
affecttheabilitytochargethebattery.The
internaltemperaturemustbebetween0℃/32℉and45℃/113℉forthebatterytocharge.If
theinternalbatterytemperaturerisesabove45℃/113℉thebatterywillnotchargeatall.
AvoidexposingtheMD‐100deviceto
fireortotemperaturesabove60℃/140℉.These
conditionsmaycausethebatterytomalfunction,generateheat,igniteorexplode.Beawarethat
itispossible,inaworst‐casescenario,fortemperaturestoreachgreaterthanthosestatedabove
in,forexample,thetrunkofacaron
ahotday.
OnlychargetheMD‐100batteryinanambienttemperatureof0℃/32℉to45℃/113℉.
Onlyqualifiedpersonnelwithappropriateservicedocumentationshouldreplacethebackup
battery.Otherwise,personalinjuryorequipmentdamagecouldoccur.
UseonlythesuppliedpoweradaptertochargetheMD‐100device.Usingunauthorizedpower
adaptersmayseverelydamagetheMD‐100device.
ForsafeoperationoftheMD‐100device,useonlychargerandaccessoriesapprovedbyDevice
Manufacturer.
Ifthe
PowerSupplyCordisdamageditneedstobereplacedbyServicePersonnelonly.Donot
usethePowerSup‐plyCorduntilreplaced.
DisconnecttheACpowerplugofthePoweradapterfromthewallsocketwhennotchargingthe
deviceanddisconnectthepowercablefromthedevice.
SpecialregulationsapplytoshippingdevicescontainingLi‐ionPolymerbatteries.Ifdropped,
crushed,orshort‐circuited,thesebatteriescanreleasedangerousamountsofheat,mayignite,
andmaybedangerousnearfires.
Theplug/adapterplugpinsinsulatethedevicefromthemainsupply.Donotpositionthedevice
inapositionwhereitisdifficulttodisconnectthedevicefromthesupplymainstosafely
terminateoperationofthedevice.
2.2Temperature
Duetouseindirectsunshineor in anyotherhotenvironmenttheMD‐100devicemayhavehot
surfaces.Thereisabuilt‐intemperaturesensorthat
monitorsthetemperature.Ifthesensor
detectshighinternaltemperature,thedevicewillautomaticallytriggeraWindowsShutDownor
