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 specific rechargeable battery and charger. ONLY
the specific 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 flashing 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.
