Answers to Commonly Asked Questions
"I can't change receiver settings, or even monitor all of them, with the UA888. Is
there something wrong with my system?"
No, there is nothing wrong with your system. You just have some older U4 receivers. Version 1.5x and earlier
require an upgrade before they can support all UA888 monitoring features, or any of the remote control fea-
tures. An Upgrade Kit is available. There are two ways to determine which version of the Shure U4 receiver
you have:
1. Turn the receiver on and hold down the "+" and "–" buttons on the receiver front panel. After a few sec-
onds, the version number will appear on the display.
2. Look for a label on the rear of the receiver that identifies it as "Version 2" or later.
"The rf and audio meters on my U4 receiver are not working properly. Is it pos-
sible for both meters on each receiver to go bad at the same time?"
It is extremely unlikely that both meters would fail simultaneously on multliple receivers. However, the accura-
cy of the U4 meters can be temporarily affected if the UA888 is turned off while the receivers are still on. Turn
the UA888 Interface Module back on and leave it on.
"Nothing happens when I try to select Open Scene. What should I do?"
You need to connect the UA888 to the U4 receiver(s). Both a hardware and a software connection are re-
quired. You can make these connections as follows:
1. Make sure the U4 receivers are properly connected to the the UA888. An RS-232 cable should run from
the 25-pin Network Interface connector on the rear panel of each U4 receiver to one of the 25-pin connec-
tors on the rear panel of the UA888.
2. Go the the main menu bar on the computer display and click on the "Set Up" heading. Select "Connect"
from the pull down menu.
"Is there a way to turn off the password protection?"
Yes. Here it is:
1. Cllck and hold on the Security heading in the main menu bar and highlight "Password" and "Deactivate
Password Protection." Then release the mouse button.
2. Type "UA888" . This will serve as a master password and override the previous password.
