Daktronics TI-2022 Portable LED Timer - Manual (Page 13)

Electrical Installation 7
Section 3: Electrical Installation
The TI-2022 contains internal batteries for power but can receive external power through a detachable
transformer cord (Figure 6).
The primary purpose of the transformer is to charge the internal battery, but the display can still be
operated while the battery is charging. The transformer and cord can remain plugged into the power
source indefinitely with no damage to the timer or its battery.
The indoor version (TI-2022-13) has a single battery, while the outdoor version (TI-2022-11) has two
batteries. On a full charge, each battery should last approximately 10 hours before recharge is
necessary. To recharge the system, simply plug the power cable into a grounded power receptacle.
The recharging unit will not overcharge the batteries. Indicator lights on the side control panel show
when the unit is charging and when it is fully charged (refer to Figure 8).
