FREQ button to scroll through the
frequency settings. Choose from four minor frequency adjustments
(F1 to F4) in order to minimize interference caused by electrical

shows current setting.
Backlight—Press the SHIFT
button, then push the LIGHT button
to switch the LCD backlight on or off. Use the backlight in low light
situations for improved visibility of the screen.
Adjust lower stem to comfortable length, and hand-tighten the
camlocks. Wrap cable snugly around the stem with the first turn
of the cable over the stem.
Insert coil connector into the 4-pin connector of the control box
by lining up connector pins. Press firmly, yet carefully, until the
O-ring is felt to be inserted, and hand-tighten.
Note: If the O-ring is properly
seated, the connector's collar can
be easily tightened; if the collar is
difficult to turn, the O-ring may
not be seated properly.
If needed, adjust the arm cuff by
removing the screw on the bottom. Move the two-piece cuff to
the other hole, reinsert the screw through the headphone cable
clip, and tighten.
