CED CED7000T - Preparation and Initial Setup; Battery Management

4.
PREPARATION
BATTERY:
The CED7000 functions on an internal rechargeable Lithium battery. The normal life cycle is 25 hours
of use or 33 days of stand-by. This estimate is based on 40 activations per hour or 1000 activations per
charge cycle and may vary with difference usage. The life of the battery should provide 500 to 1,000
re-charges. The full performance of a new battery is achieved only after two or three complete charge
and discharge cycles. The battery can be charged and discharged hundreds of times but it will eventu-
ally wear out. When the usage times are noticeably shorter than normal, it is time to purchase a new
battery.TheCED7000Timerisdesignedtouseaspecicrechargeablebatteryandcharger.ONLY
thespecicbatteryandchargerpackagedwiththeCED7000shouldbeusedwiththetimer.Returnthe
timer to CED or Double-Alpha Academy for a battery replacement. Contact us for prices or visit our
web sites for more details.
To charge the battery, connect the lead from the charger to the DC socket on the bottom of the timer.
Connect the charger to an AC wall socket. If the battery is completely empty, it may take a few minutes
before the charging indicator appears on the timer display. While the timer is charging, an escalating
battery symbol will appear on the right side of the LCD display window. Charging time depends on the
formofcharging.Usingthechargerwilltakeaprx.2hours.UsingtheOptionalBatteryPackwilltake
aprx. 2.5 hours if the timer is not used during this process. An optional Auto Charger is available which
plugsintothevehiclecigarettelighterjack.Chargingshouldtakeaprx.2hoursbythismethod.
Unplugthechargerfromtheelectricalplugandthetimerwhennotinuse.Donotleavethetimercon-
nected to the charger. Overcharging may shorten its lifetime. If left unused, a fully charged battery will
lose its charge over time. Temperature extremes can affect the ability of the battery to charge. Leaving
the battery (timer) in hot or cold places, such as in a closed car in summer or winter conditions, will
reduce the capacity and lifetime of the battery. Always try to keep the battery between 10 C and 32 C
(50Fand90F).ItisIMPORTANTtonotethattheperformanceofbothbatteryandLCDdisplaywill
be particularly limited in temperatures below freezing.
A“BatteryIndicator”isconstantlydisplayedonthetimer’sLCDscreen.Asthebatterydrainspower,
the symbol will turn from all black to clear displaying the amount of battery life remaining. The battery
symbolhasthreelevelsofindication.Full,half,andempty.Whenthebatteryreachesalowcharge
level,thebatterysymbolwillbeginashingindicatingtimetorechargethebattery.Thisprovidesam-
ple warning to charge the battery in order to prevent timer failure due to loss of battery power.
Ifthebatterydrainstoolow,awarningmessage(LowBatteryshuttingofftimer)willappearonthe
LCD display and within 30 seconds of usage, the timer will shutdown. The retention of stored data in
theCED7000willremainintactaslongasthebatteryhasaminimumof3.6V.
