Selectable RF Transmission Power

The HH transmitter allows the user to select from among 

two power settings

†

 depending on the needs of the 

situation. The lower RF power setting uses slightly less 

current, thus battery life is enhanced. The higher power 

setting provides greater range and resistance to drop-

outs. Selecting the RF power is accomplished using the 

control menu.

Mute and Talkback Functions

The button on the back of transmitter below the head 

can be used to actuate an audio mute condition. This 

button can also be disabled using the control panel 

inside the battery compartment. An alternative function 

that can be actuated by this button is a talkback func-

tion. In this state, the transmitter sends a signal to the 

Venue receiver when the button is pushed - the receiver 

then switches the audio to a second output which can be 

routed differently. 
This function can be used for talkback, cueing or other 

purposes depending on the application.

Consumer Alert for US Users - FCC Order DA 10-92

Most users do not need a license to operate this wireless microphone system. Nevertheless, 

operating this microphone system without a license is subject to certain restrictions: the system 

may not cause harmful interference; it must operate at a low power level (not in excess of 50 

milliwatts); and it has no protection from interference received from any other device. Purchasers 

should also be aware that the FCC is currently evaluating use of wireless microphone systems, 

and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC 

(TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/

wirelessmicrophones.   To operate wireless microphone systems at power greater than 50mW, you 

must qualify as a Part 74 user and be licensed. If you qualify and wish to apply for a license go to:
