repeat the procedure in a darker location or somehow shield the link from outside light to successfully
program the transmitter with the pre-programmed group and channel info from the receiver.
Manually Programming
If, in a very bright light situation, the IR ASC™ Sync function does not work, manual channel
selection is preferred. Use a pen tip to press the UP or DOWN BUTTONS (30) once quickly, the
LCD backlight will light up displaying the channel selection menu for manually picking a desired
channel, and a channel is changed accordingly. Each subsequent pressing of the UP or DOWN
BUTTONS will enable single step channel selection from 1 of 100 pre-programmed channels (or
hold down for faster selection). Release the button and wait for the Channel LCD display to stop
flashing to confirm the channel selection into the memory. The LCD backlight will also turn off
momentarily.
If you miss a channel during selection, keep pressing either the UP or DOWN BUTTON until you
reach it. This completes the manual channel programming.
Note: If no button is pressed within 3 seconds, the programmed content is stored for use.
CAUTIONS AND TROUBLESHOOTING
Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume,
transmitter location and speaker placement.
Please also note the pickup pattern characteristics of the microphone selected. Unidirectional
microphones are more resistant to feedback. However, they pick up sound sources best that are
directly in front of the microphone. Also, mics that are farther from the sound source (such as a
handheld) require more acoustic gain and thus are also more prone to feedback than close-
source mics.
No or low audio
If you are not getting audio through the system, carefully re-check all setups. Especially note
that the receiver and transmitter must be set to operate on the same RF channel. Also confirm
that the transmitter’s POWER SWITCH (18, 25) is not in the MUTE/STBY position. The receiver’s
UNBALANCED SUM OUT (10) is adjustable so make sure the VOLUME CONTROL (2) is set properly.
RF Interference and Finding Open Channels
The FCC mandates the following information be provided to all end users of this equipment:
Consumer alert
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 50mW); 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 www.fcc.gov/cgb/consumerfacts/wirelessmic_factsheet.html.
If you encounter slight receiving interference when the transmitter is far from the receiver
(from other than an operating TV station on the same frequency), it can often be overcome by
adjusting the receiver‘s MUTE LEVEL RF SQELCH (11) — see Adjusting the Squelch. If receiving
interference on a selected channel with the transmitter off, you must reprogram the receiver
and transmitter to a different channel.
To reprogram, you must first find an open channel. To do this, follow the procedure outlined in
