Locking or Unlocking the Control Panel
Important: The only way to unlock a locked transmitter is to remove the
battery. It cannot be unlocked or powered off using the buttons. The unit will
always power up in "unlocked" mode.
Using the Polarity-Reversing
Barrel Adapter with
Measurement Microphones
A polarity adapter may be needed if
you experience noise, low output or
distortion with meaasurement micro-
phones such as Earthworks M30 or
Rode NTG3.
Insert the barrel adapter provided with
the HM transmitter between the micro-
phone and transmitter as shown.
NOTE: This adapter is included
with the TM400 test and
measurement system, but is
available as a separate item
with the HM transmitter and
other wireless equipment.

The Lock mode protects the transmitter from
accidental changes to its settings.
1) Ensure the HM setup is complete.
2) Simultaneously press both the UP and DOWN
arrow buttons to start the Lock timer. When the
timer reaches zero, "Loc" is displayed and the
controls are locked.
