OPERATING INSTRUCTIONS
UH-16 Handheld Microphone Transmitter
10
1. Powering the Transmitter
Slide open the BATTERY COMPARTMENT COVER (14) and remove, exposing the BATTERY
COMPARTMENT (15). Insert 2 fresh AA ALKALINE BATTERIES (16), observing the correct polarity as
marked, and slide the COVER back, closing the BATTERY COMPARTMENT.
Two fresh alkaline AA Batteries
can last up to 12 hours in use, but
in order to ensure optimum
performance, it is recommended
that you replace the batteries after
every 8-10 hours of use.
All controls are at the base of the
microphone. Turn on the UH-16 by
sliding the OFF/STANDBY/ON
SWITCH (17) to the STANDBY
position (transmitter on, audio
muted) or the ON position
(transmitter and audio both on).
The BATTERY INDICATOR LED
(18) will give a single quick flash, indicating usable battery strength. In the case of dead or low batteries,
the LED will either not go on at all, or will stay on continuously, indicating that the batteries should be
replaced with fresh ones. If the Tone Squelch™ is activated on both transmitter and receiver, the LOW TX
BATTERY ICON (11c) on the receiver’s LCD DISPLAY (11) will switch from the battery OK to the LOW
battery mode. See CHANNEL DISPLAY AND UP/DOWN BUTTON OPERATION, page 15 and UHF-16
OPERATING INSTRUCTIONS, page 8. The channel
number on the CHANNEL LED DISPLAY (19) will
extinguish in 10 seconds. The activity indicator
“ ’’ or “ ’’ LED will remain on in the DISPLAY. See
CHANNEL DISPLAY AND UP/DOWN BUTTON
OPERATION, page 15.
2. Selecting the Operating Frequency
In order for the system to operate properly, the same
channel (frequency of operation) must be selected for the
UH-16 transmitter as was chosen for the UHF-16 receiver.
Press either the UP or DOWN CHANNEL SELECT
BUTTON (20) until the channel number indicated on the
2-segment CHANNEL LED DISPLAY (19) matches that of
the UHF-16 receiver.
3. Selecting the Tone Squelch™ Mode/Activity Indicator
Hold both the UP and DOWN BUTTONS (20) at the same time for 1 second. The Tone Squelch™ will cycle
from On to Off. See the CHANNEL DISPLAY AND UP/DOWN BUTTON OPERATION, page 15.
(Note: If the receiver is configured for Tone Squelch™ mute, the transmitter must also be configured to
send the tones, otherwise the receiver audio will remain muted. The signaling tones are also used to
indicate the transmitter battery status on the receiver BATTERY ICON (11c) display. If Tone Squelch™ is
defeated, this function will not be operational.)
