Operation
Specifications
Storage
To properly store the device for an extended period of time, i.e. two weeks or more, remove
the batteries and store the device in a dry location. Store all the operating components in
the carrying case. Batteries should be stored in the carrying case, in a dry location at 50° F
to 86° F (10° C to 30° C) and away from direct sunlight.
Rechargeable batteries slowly lose their charge in storage so they should be recharged
every six months. The batteries can lose their capacity to hold a charge when they are
stored for long periods of time. You can renew their capacity by charging and discharging
them several times. If your batteries do not retain a charge during standard operation,
contact Empi Customer Service at 1.800.328.2536.
Dispose the unit in accordance with national, state or local regulations. If needed, ship the
used device, postage prepaid, to the Empi Service Center for proper disposal or recycling.
Please enclose a note indicating that the item is being returned for disposal or recycling.
Outside of North America, contact your Authorized Empi Distributor, or contact Empi
directly at 1.651.415.9000.

Cleaning
Cleaning the device: Use a damp cloth moistened with mild soap and water to clean
the exterior of the device. Use of other cleaning solutions may damage the case. Never
immerse the device in water or other liquids. Do not use cleaning fluids or solvents to
remove stains or dirt. These liquids may damage the plastic case and lead wires.
Cleaning the battery contacts: Gently clean the battery contacts using a cotton-tipped
swab soaked in rubbing alcohol. Do not use sandpaper or other abrasive material.
Cleaning the lead wires: Periodically wipe the lead wires clean with a cloth dampened in a
mild soap solution, then gently wipe them dry. Use of rubbing alcohol on the lead wires will
damage the insulation and dramatically shorten their life.
Maintenance
Check the unit before each use for signs of wear and/or damage. Replace wear items as
required. Send damaged units back to factory for repair.
Wear items are:
1. Electrodes
2. Lead wires
3. Batteries
