Novatac EDC-120P User Manual - 6. Low Battery Indication.
light’s settings will remain unmodified. If there is insufficient power to
remember the factory settings you will see two seconds of very rapid
flashing. The default settings will be restored but when the battery is
changed or a soft reset is done the change will be forgotten.
6. Low Battery Indication.
(light drops down to 50% of its current selected brightness)
As the battery becomes depleted, it will not be able to supply enough
power to run the light at its selected brightness. It will momentarily
turn off, then back on at half of its previous brightness. This step
down process repeats as the battery is depleted. When the lowest
brightness level is reached, the light will blink continuously until the
battery can no longer power the light. The battery should be replaced
before the light reaches this point.
The light remembers the restricted brightness level as long as it
remains on. Turning it off and back on resets the restricted brightness
level. This gives you access to all brightness levels if the battery can
supply enough power.
If a dying battery must be used, a lower brightness level should be
selected immediately. The lower the brightness setting, the longer
the battery will last.
If there is continued use of a rechargeable battery after the light
has dropped to its lowest brightness level, it is assumed you are
in an emergency situation and the light will sacrifice the battery to
remain on.
The length of time the battery will last varies depending upon how
the light is used, the type and quality of battery being used, and
how cold the temperature is. Due to LED tolerances, you will see
flashlight to flashlight runtime variations, even being operated under
similar conditions.
Low battery behavior can occur if the battery contacts become dirty.
To clean, gently wipe the battery contacts in a counter-clockwise
direction, or the spring in a clockwise direction using a clean, dry
cloth. This is normally sufficient to remove dirt. If in doubt, the battery
should be replaced.
