Getting to know Ultra

Ultra wasn't in the water long
enough to make it safe. Make sure
the water sensors stay fully
submerged throughout the whole
treatment.
It's cold out and Ultra needs to
warm up. A treatment will take a
little extra time while the bulb
reaches the right temperature. This
feature adds a few seconds to
ensure safe treatment.
Ultra didn't have enough power in
its battery to safely treat the water.
Charge and try again.
Ultra couldn't treat the water
because either the lamp is
completely used up or it has been
damaged.

Ultra Charging Options

Ultra's USB-rechargeability offers a variety of
recharging choices. Power up from an electrical outlet,
a computer's USB port or a portable solar panel.
From an outlet (2-3 hours)
Attach the USB cord to a wall adapter's USB port and
plug both into a wall outlet. Plug the cord's micro USB
end into Ultra's micro USB port and place it on a
secure surface.
From a computer (3-5 hours)
Plug the USB end of the included cord into a
computer's USB port and connect Ultra via the micro
USB end of the cord. Make sure that the computer is
connected to a power source and doesn't go to sleep
during charging.
From a solar charger (depends on charger)
Connect Ultra to a solar charger via the USB cord and
position the solar charger so that it is directly exposed
to the sun. Reposition the solar charger during the day
for best performance.
The water is safe to drink!
Ultra's bulb has around 75%
of its life left (approximately
6,000 treatments) and its
battery is roughly 75% full.
The treatment was
successful but Ultra's UV
bulb is near the end of its life
and has fewer than 100
treatments left.
If Ultra's battery is charged, you are carefully following the
operating instructions and Ultra still isn't working, it might
need professional repair work. Either bring Ultra to your
local dealer or get in touch with us at 1-888-826-6234. Do
not try to fix Ultra yourself.

Tried charging a dead Steripen without luck. Is there a replacement battery or is the whole thing trash?
