PRODUCT FEATURES
The Dorval® Bathroom Collection diverges from conventional expectations with regal accents and a powerful design that commands your attention. Touch it on. Touch it off. Or go completely hands-free. Delta® Touch2O® with Touchless Technology helps keep your bathroom clean by giving you three ways to operate your faucet: manually with the handle, with a simple touch anywhere on the spout or handle, or by placing your hands near the faucet. The high-tech capacitance sensing capabilities of Touchless faucets allow the flow of water to be activated by breaking the capacitance field anywhere around the device, unlike traditional hands-free infrared sensors which require your hands be in a particular place and are sensitive to lighting conditions and clothing and skin color. WaterSense® labeled faucets use at least 20% less water than the industry standard — helping you save water without compromising performance. You can install with confidence, knowing that this faucet is backed by Delta Faucet's Lifetime Limited Warranty on non-electronic parts and finishes and 5-Year Limited Warranty on electronic parts.
  • Operate hands-free by placing your hands near the faucet, with just a touch anywhere on the spout or handle, or manually using the handle
  • Helps keep your faucet cleaner, because washing the mess off your hands shouldn’t involve making a mess of your faucet
  • Automatic water flow shut-off after two minutes helps conserve water
  • Batteries last approximately 1 year if using AA batteries or 3 years if using C batteries, based on 20 minutes of usage per day
  • Optional A/C adapter EP102157 may be ordered separately
  • Diamond Seal® Technology is less hassle to install and helps your faucet perform like new for life, reducing leak points and lasting twice as long as the industry standard
  • Everything you need is together in one convenient box, including integrated InnoFlex® PEX supply lines
  • Fits 1 or 3-hole 4-inch installations
  • Optional red/blue temperature indicator ring included
  • Metal push pop-up drain assembly in matching finish (included) is ADA compliant and simple to install, operate and clean
  • ADA compliant
  • WaterSense® labeled faucet uses at least 20% less water than the industry standard without compromising performance
  • High arc spout does not swivel
  • 3/8-inch compression fittings
  • Backed by Delta Faucet's Lifetime Limited Warranty on non-electronic parts and finishes and 5-Year Limited Warranty on electronic parts

Re: 556T-DST Dorval Touch2O Technology Bathroom faucet 1) The hands free feature was accidentally de-activated. How can I activate it. 2) When the battery runs out, will the faucet still operate manually. If not, is there a way to make it so.

Asked by: mrsOwl
Hello mrsOwl, Thank you for contacting us, I would be happy to help you. Unfortunately when the batteries get low, the faucet will not operate until you change the batteries. Also please follow directions below on how to reactivate the hands free setting: Put the handle in the off position Wait 5 seconds Tap the spout 6 times within 4 seconds. Notice the light flashes red & blue As soon as the light stops flashing, tap the spout 6 times within 4 seconds. Prox mode is now on. Please contact us back if you have any questions or need further assistance.  Best Regards,  Nicole
