Transmitter Power Level Select
The Line 6 digital transmitters give the option to select a lower power transmission, which is useful for
minimizing interference when using them along with WiFi or other 2.4 GHz devices, and for extending
battery life when the transmitters are used closer to the receiver antennas. When you are using wireless
systems on the same channels at nearby venues or stages, the lower power setting will often allow them
to work at each location without interfering with each other. For maximum range, use the (default)
higher power setting.
To set the transmitter power, press and hold the SELECT button until the channel screen appears.
Quickly press the
SELECT button one more time to reach the [POWER] screen. Press the ON/MUTE
button on the handheld or the
VALUE button on the beltpack to change between [HI] and [LO] (Power
Save). Press and hold the
SELECT button to select and go back to the main screen.
Note, If the transmitter is set at LO power and you experience short range or interference, change it to
the HI setting to increase the range. Alternately, position the transmitter closer to the receiver antennas,
make sure the antennas are line-of-sight, or select another frequency that has less interference.
Locking, Unlocking, and Muting the Transmitter
The THH12 and TBP12 transmitters can be locked to prevent accidental button pushes from handling
during use. When locked, the user cannot mute or turn off the transmitter, or change the frequency or
other settings, assuring that an error with a transmitter will not interrupt the event. After use, it is easy
to unlock the transmitter to turn off or change settings. When not locked, the transmitter can be muted
so that it keeps transmitting but audio is temporarily disabled.

MUTE
To mute the THH12 handheld, quickly press the ON/MUTE button until it clicks; press again to
unmute. The word [MUTED] will appear in place of the transmitter name, and the backlight will stay
lit. To mute the TBP12 beltpack, push and briefly hold the
MUTE button on the top of the pack; press
again to unmute. The display works identically to the handheld. When the mic is muted and you press
the
SELECT button to enter another parameter page, the word [MUTED] will remain in tiny characters
in the left center of the display as a reminder. When a transmitter is [MUTED] the red
MUTE LED will
light on the receiver.
To lock the THH12 handheld, turn it on and assure that the desired settings are completed, and that the
receiver display shows the signal. Unscrew the end of the battery compartment, and locate the micro-
switch on the back; move it to the right toward the lock symbol. Test by pressing the
ON/MUTE or
SETUP buttons, and the word [LOCKED] will appear on the top line of the briefly lit display. Unscrew
the compartment and move the switch to the left to unlock.
