Optional Accessories

Headset
A headset with 2.5 mm jack plug (part number HS001) may
be used with the 500XP. When plugged in, the loudspeaker is
disabled and all sound is reproduced in the headset.
Use of any other headset may compromise user safety. The
output level limiting built into 500XP is tailored for Greenlee
headsets. Use of other headsets may result in sound levels that
could, with long-term exposure, cause hearing damage.
Complementary Products
The 500XP can be used with any audio tone generator that
produces a signal of a few volts or more in the frequency
range 400 Hz to 3 kHz when in wideband mode. For optimum
performance in filtered modes, precision tone generators from
Greenlee are recommended because they produce precise
filtered frequencies of 577 Hz and 983 Hz, chosen as not being
harmonics of AC mains power at 50 Hz or 60 Hz. Examples are
77GX, TG600J, 177, PE7780, and tone generator features of
NC-100, NC-500, and the Sidekick range of testers.
®
Use with other oscillators in the filtered modes is not recom-
mended as their imprecisely controlled, low-cost circuitry may
produce tones that are filtered out by 500XP and are therefore
not audible when noise cancelling filters are active.
