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 
eld-replaceable antenna mounted on the transmitter. The antenna 
simply screws into the transmitter’s antenna tting. Check the installed 
antenna occasionally to make certain it is snugly attached (only nger-
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.
