LED STATUS INDICATORS

Power LED indicates when the unit is ON.
Measurement LED indicates when measuring (Bar or
Line graph screen). LED is OFF when in Select Screen
Low Battery indicates when the batteries need a charge
or replacement.
CONNECTION AND USE
Connect the AP to be tested using the supplied SMA
connection kit to the ButterFly RF input connector, the
SMA connector on the top of the ButterFly. Make sure
both the AP and the ButterFly are on If not already
displayed, select either the bar or line graph measure-
ment. If the current RF power indicated by the text
display in the lower left of the display is –40 dbm and
never changes, check the connection between the AP
and ButterFly. If RF power is indicated by this portion
of the display, but no bar or line is displayed, reduce
the threshold using the Down key until the display
becomes active.
BATTERY REPLACEMENT
When the battery low indicator comes on, the bat-
teries must be replaced or recharged. To remove the
batteries, disconnect the ButterFly RF input and turn
the power switch to the off position. Hold the Butterfly
with the bottom facing you, the SMA RF input facing
upward. Locate the tab on the battery cover and using
your finger, gently pull the tab toward the bottom of the
unit until the cover comes away from the unit. Remove
the batteries and replace, observing the battery polari-
ties marked on the plastic of the battery compartment.
Replace the battery cover by positioning the tab on the
bottom of the cover into the slot in the bottom of the
battery compartment. Push on the cover until the tab
on the top clicks back into position. The unit is now
ready to resume use.
