Digital TENS AA Unit

Ultima 5 Digital TENS Unit With Timer. Transcutaneous Electrical
Nerve Stimulation (T.E.N.S.) systems, also known as TENS Units,
are designed to relieve both acute and persistent pain without shots,
drugs or narcotics. They send gentle electrical impulses through
the skin to the nerves to suppress pain by scrambling the pain signals
before they reach the brain. A "TENS unit" is a pocket size, portable,
battery-operated device that sends electrical impulses to certain
parts
of the body to block pain signals. The electrical currents produced
are
mild, but can prevent pain messages from being transmitted to the
brain and may raise the level of endorphins (natural pain killers
produced by the brain).

• Treatment Timer: Continuous, 15min, 30min, 45min, 60min
  selectable
• Operation:
  1. When mode changes, the intensity will automatically go
  down
  to zero
  2. When the unit is turned on, it will automatically enter
  the mode
  that the unit had worked in before the unit was turned
  off 3. When
  the pulse rate, pulse width or intensity is being adjusted,
  the
  auto-repeat function is available, when the key is held
  down over
  1 second, it will automatically increased/decreased 1
  step per 1/4
  second 4. When the batteries are low, the symbol of
  battery is flashing in 2 Hz indicating that the batteries should
  be replaced 5.
  Automatic shut off: When the unit intensity levels are
  0 on both channels, and it has not been in use for 5 minutes,
  the unit will be shut off automatically.
