HD-2 Operation and Installation Manual
GENERAL INFORMATION
INSPECTION
Inspect the degausser for shipping damage as soon as it is unpacked. If the degausser
or any accessories are damaged or fail to operate correctly, notify carrier and Garner
Products, Inc. immediately. For assistance from Garner Products, Inc. call (916) 784-
0200 or fax (916) 784-1425. For warranty information, please refer to the Warranty
section inside this manual.
INTRODUCTION
The Garner Products, Inc. Model HD-2 is a continuous duty capacitive discharge
degausser. The HD-2 is designed to erase hard drives and tape cartridges that fit
inside the drawer. The convenient drawer loading design accommodates many
different types and sizes of media, without the need for adapters.
MAGNETIC FIELDS
Magnetic fields measured around perimeter
The HD-2 produces a single focused magnetic pulse lasting less than 1/20 of a second.
The focused intensity allows the HD-2 to erase today’s highest coercivity media while
also limiting the magnetic field exposure to 1 second for every 20 pieces of media
degaussed.

field(Front Panel)
Note: The testing room measured 0.4 gauss before degausser was plugged in.
Average Operational Distance (AOD) from user to the HD-2 is 12-18 inches (30-45cm).
According to the American Conference of Governmental Industrial Hygienists (ACGIH)
Threshold Limit Values (2005) - Static Magnetic Fields, whole body exposure limits
recommended for an 8 hour shift are 600 gauss. Because of the short duration of each
pulse from an HD-2 (1/20th* of a second) and the extremely small magnetic field outside
of the unit (<19 gauss, AOD) the total 8 hour whole body exposure is 1/120th of the
recommended limit.
*Pulse duration was rounded to ½ second per discharge for calculations to cover any build up of
magnetic fields generated before or after discharge.
Pace Maker Users
Due to stray magnetic fields, consult your physician before operating.
