Preface HE4000 Encoding System
Route Power Cords Safely
Route power cords so they are not walked on or pinched. Pay particular attention to cords and
connections at the plugs, receptacles (such as power strips), and the point where they exit from
the HE4000 and attach to other equipment. Do not place any items on or against power cords.
No Stacking
Do not place or stack any objects on top of the HE4000. Other equipment may be placed in a
rack or on a shelf above or below the HE4000, but never stacked directly on top of it.
Protect Against Lightning and Power Surges
When the HE4000 is installed, have the professional installer ground the system to protect
against voltage surges and built-up static charges. For information on grounding standards for
electrical and radio equipment, refer to the electrical code in the country of installation.
Protect the HE4000 from lightning and power-line surges during a storm by unplugging it from the
wall outlet and disconnecting the coaxial cable.
Do Not Open the HE4000
There are no user serviceable parts inside the HE4000. It should be returned to and/or serviced
by Comtech Tiernan Video, Inc.
Keep Objects Outside
Touching internal HE4000 parts is dangerous to both the user and equipment. Never put any
object, including fingers, through slots or openings, as this could result in touching dangerous
voltage points, short-circuiting parts, electric shock, or fire.
There are no user-serviceable parts inside the HE4000. If an object falls into the equipment,
unplug the unit and contact the ComtechTV Customer Service Department, as serious damage
could occur to the HE4000 or its components.
Clean the HE4000
Before cleaning the HE4000, unplug it from the wall outlet. Do not use any type of abrasive pads,
scouring powders, aerosol cleaners, or solvents such as alcohol or benzene.
Use only a clean, soft cloth lightly moistened with a mild detergent solution. Wipe all equipment
with a clean, soft cloth lightly moistened with water to remove the detergent solution.
