Connecting Input Audio Source
Lapel/Head Mic Uses (UB-800 LT/HM)
The mini 3.5mm locking INPUT JACK (39) is for connecting the audio input from a
lavaliere/lapel Mic (LT), a Head Mic™ (HM), or an instrument (GT) cable, depending
on which transmitter version is being used. Secure the connection to the cable by tighten-
ing the cable mini plug’s outer ring counterclockwise. When ready to play, slide the
AUDIO MUTE ON/OFF SWITCH (40) to the ON position to un-mute the audio.
Adjust the INPUT VOLUME LEVEL (43) on the transmitter for suitable level.
Instrument Use (UB-800 GT)
Secure the connection of the GT (instrument) cable by tightening the mini plug outer
ring counterclockwise onto the 3.5mm locking INPUT JACK (39). When ready
to play, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position to
un-mute the audio. Adjust the volume on the receiver for one-to-one unity gain with
a hardwired cord or select up to an added 4-5dB boost by adjusting the receiver
volume to maximum for normal use with guitars and bass guitars.
Note: The audio level should be adjusted on the instrument as when using a hardwired
cord.
Programming the UB-800 to the Selected Group/Channel (frequency)
The transmitter must be programmed to the same frequency as selected for the receiver
via automatic synchronization using the IR ASC™ Sync function. It cannot be pro-
grammed on the transmitter itself. See next section “6. Selecting Group/Channel,
IR Programming and Simultaneous Multichannel Operation”.
Note: Note: The transmitter should be turned ON and ready for the IR communica-
tions with the receiver IR receptor for the following process.
Note: If no button is pressed within the five seconds period during a selection, the
program is terminated and the process needs to be repeated.
Note: For normal operation, the transmitter should have the same channel as dis-
played on the receiver.
Choosing Group/Channel for the System
The receiver offers a choice of 15 groups: 10 that are Factory PRESET (Group 11
to 1A) and 5 that are User SELECTABLE (Group 1B to 1F). If the Factory PRESET
Group mode is chosen, only a limited numbers of channels are available in these
groups. For most convenient setup, each of these groups offers from 3 to 14 channels
(depending on group selected) to choose from that are factory preset for simultaneous
multichannel operation compatibility and are retained in memory after the receiver
is powered off. For the User SELECTABLE Group 1B-1F mode, a letter “U” will lit up
on the LCD DISPLAY (5) instead of the CHANNEL (12) number as in the Factory
PRESET Groups. Each User SELECTABLE Group has 800 channels to choose from
either by manually selecting a channel or using the Auto-Scan in 1MHz segment
increments at a time within the frequency band and they are retained in memory

AND SIMULTANEOUS MULTICHANNEL OPERATION

Programming the U-800 to the Selected Group/Channel (frequency)
The Receiver must be programmed for a Group/Channel (frequency) first then auto-
matic synchronization using the IR ASC™ Sync function to the transmitter. For system
set up procedures, see next section “6. Selecting Group/Channel, IR Pro-
gramming and Simultaneous Multichannel Operation”
UH-800 Handheld Microphone Transmitter (HT)
Setting up the UH-800 Transmitter
The UH-800 requires two AA alkaline or NiMH batteries to operate (do not mix
types). Installing batteries by unscrewing counterclockwise the BATTERY COVER
(29) and slide down, exposing the BATTERY COMPACTMENT (32). Insert two
fresh AA BATTERIES (31), observing the correct polarity as marked, and screw the
cover back on to the microphone. Make sure the cover is screwed clockwise complete-
ly. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure
optimum performance, it is recommended that you replace the batteries after every
6-8 hours of use.
Powering the UH-800 Transmitter On/Off
Turn on the UH-800 by sliding the AUDIO SWITCH (36) to the OFF position first.
Then slide the POWER SWITCH (35) to the ON position. The POWER ON LED
(33) will stay on, indicating that the transmitter is now on. The BATTERY LED (34)
will stay off, indicating usable battery strength. In the case of a dead or low battery,
the low battery LED will light red continuously, indicating that the batteries should be
replaced with fresh ones.
To preserve battery life, turn the transmitter off when not in use. To turn the transmitter
off, slide the RF POWER (35) switch to the OFF position. The POWER ON LED
(33) is not lit up, indicating the unit is off. The MUTE ICON (6) on the receiver
should be on, muting the audio out.
At power off the transmitter will store the last settings entered and re-display them at
the next power on. The default factory setting is Group 11, Channel 01.
For optimum performance, an AUDIO INPUT LEVEL (30) is provided. Adjust the
gain by turning the control with a small screwdriver. It is recommended that the level
be set at about 1/2 maximum. Experiment and set for maximum possible gain without
audible distortion on the high level peaks. (Note: Turning down the gain too much
can compromise the signal-to-noise and it is not recommended.)
The microphone is now ready to use. The diversity A/B INDICATORS (9) on the
U-800 receiver should now be on, indicating a received signal from the transmitter.
When ready to speak, slide the AUDIO MUTE (36) to the ON position. The MUTE
ICON (6) on receiver should be off. Adjust the volume of the receiver as per the Au-
dio Output Microphone Connection section of the above U-800 receiver instructions.
