R2020 Wired Display
Storage (Continued)
It is very important to not permit the Gell Cell
batteries used inside these displays to completely
discharge. The battery life will be shortened
significantly if they are allowed to discharge too
much.
When the displays are NOT being used, Push and
Hold the OFF button to turn the display off, then
connect the display to the wall transformer and plug
the transformer into AC power. The battery charger
is an intelligent one that maintains a trickle charge to
keep the batteries at full charge, but shuts off when
necessary to prevent any possibility of over
charging.
Your display will always be ready for use and should
be able to run all day on a single charge
.
