6. Extended Functions

6.1 LinkTalk

LinkTalk is a special feature that allows two Fiber Meter
handsets to function as an audio communication system
over duplex multimode fiber. This feature provides half-
duplex voice communication between the Main Unit
and Remote Unit.
To function, Fiber Meter handsets must be connected using
a pair of multimode fibers with one handset set to REMOTE
and the other operating in EXTENDED FUNCTIONS as
shown on the following pages.
LinkTalk can be activated following any Autotest—even
if the test fails to meet the selected cable standard—
provided the link loss on each cable is less than 10 dB.
LinkTalk can be activated from any Autotest Summary
display screen, any Autotest Loss screen, or any Autotest
Margin screen by pressing the F3 button.
LinkTalk can also be activated in EXTENDED
FUNCTIONS by using the procedure on the next page.
