Headphones - Teknetics Alpha 2000 Owner's Manual

HEADPHONE JACK
The detector has a 1/8" & 1/4" headphone jack on the left side of the
housing.
Optional Headphones come standard with a 1/8" stereo plug (the 1/4"
adapter is not required).
When the headphone jack is connected, speaker audio is disabled. Using
a detector with headphones facilitates detection of the weakest signals
and also extends the battery life.
This device is to be used with interconnecting cables/headphone cables shorter
than three meters.
