ume of the receiver as per section 12 (UWS-1K Receiver: Connecting Audio Output).
[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that
acoustic feedback (howling or screeching) will be avoided.]
[Note: The
RF Level Meter (12)
and the
Diversity Indicator (13)
on the receiver are “ON” in
normal use with the audio “ON” (not muted). When the transmitter is “ON” but muted, the RF Level
Meter will stay “ON” but the Diversity Indicator wil be “OFF”.]
(Note: The 2 AA batteries loaded into the bottom half of the UH-1K function as a built-in antenna.
For proper operation and best operating range the transmitter should be held above that area so as
not to hand block the antenna and lessen the transmission strength.)
