TIPS FOR ACHIEVING OPTIMUM PERFORMANCE

•

Maintain a line of sight between the transmitter and receiver antennas.

Use the proper receiver antennas.

Do not obstruct the receiver antennas.

Avoid operating near metal objects.

Never use two transmitters set to the same frequency concurrently.

Keep distance between transmitter and receiver as short as possible.

Monitor the UP4’s PWR LED; if the PWR LED goes into low battery mode (red light) replace old battery with a fresh battery immediately.

For added protection, replace batteries before each shoot.

TROUBLESHOOTING

Some common problems and their solutions are identified in the table below. If you are unable to solve a problem, contact your dealer or the Shure Service Department at 1-800-516-2525 (7:30 am to 4:00 pm, Central Standard Time). In Europe, call 49-7131-72140; other international users call Shure in the U.S.A. at 847-866-2200.

	Two transmitters may be operating on the same frequency. Locate and turn one off or change frequency.
	Signal may be too weak. Reposition antennas closer to the transmitter.
	Make sure the antennas are properly attached.
	Turn the UP4 receiver to the On (Tone Key Off) position. This will allow the receiver to pass noisy or
	unwanted interfering signals. If interfering signals are detected, change frequencies on both the receiv-
	er and the transmitter.
Noise from receiver with transmitter off.	Remove local sources of RF interference, such as lighting equipment.
	Try using another frequency.
