noTe: Loss of power for around 20 ms during transfer will show up as a
slight flicker in incandescent lamps because the filament of incandescent
lamp does not cool down immediately in such a short duration. However,
a Compact Fluorescent Lamp (CFL) will switch off (its Holdup time is
< 20 ms) and switch on again after some time because the drive circuitry
of the lamp shuts down and takes some time to reactivate to re-light the
lamp. Hence, this symptom in a CFL will falsely indicate a larger transfer
time. Computers, audio video devices and other electronics normally
have holdup time of > 20 ms and will not be affected by this short
interruption of power.

The main Bi-directional Transformer is protected against over temperature
during Battery Charging Mode by reducing the charging current to
50% if the transformer temperature > 120°C. Hence, during charging
process, the internal charging current being displayed on the LCD display
(SCREEN 4 and SCREEN 5) might drop to half the value when the temp
> 120°C. Once the transformer cools down, the charging current will
resume to the full value. This cycling may repeat a number of times till
the transformer temperature does not rise > 120°C.
When in "Utility Mode", the Green Status LED will be steady and the
following 6 LCD screens of information can be accessed in the Utility
Mode. The screens can be scrolled using the "Up" or "Down" Keys.
