Battery Indicator
After the battery is installed, turn on the power switch (located on
the bottom of the handheld transmitter and on the top of the UniPak
transmitter). The battery indicator LED (
Fig. G/H
) should turn red. If it
does not, the batteries are installed incorrectly or they are dead.

Transmitter Antenna
The ATW-T210a UHF UniPak
®
body-pack transmitter includes one
field-replaceable antenna mounted on the transmitter. The antenna
simply screws into the transmitter’s antenna fitting. Check the installed
antenna occasionally to make certain it is snugly attached (only finger-
tight). If the received signal is marginal, experiment with different
transmitter positions on your body or instrument or try repositioning the
receiver.
Do not attempt to modify the transmitting antenna. Replace
it only with the same parts,
available from the Audio-Technica Service
Department.
