5. OUTPUT (#8) - switch to the appropriate position depending on whether the 500UDR

is plugged into the ‘LINE’ or ‘MIC’ input on the camera.

6. PHONE JACK (#11) - nominal 30 Ω headphone/earphone jack. Use either 3.5mm

mono or stereo (mono to both ears) connector. Earphones with an impedance

between 30 Ω and 300 Ω should provide adequate volume while headphones

with an 8 Ω impedance will most likely provide volume that is too low.

500UDR TROUBLESHOOTING

The single most important thing to ALWAYS check when trouble arrises are the batteries.

Make sure they are fresh and the POWER LED is glowing brightly.

SYMPTOM CAUSE

No POWER LED a. Receiver switch is set to “OFF”

b. External 12VDC power source is not connected or is mal-

functioning

c. Dead or very weak batteries

No ANT LED a. Transmitter battery dead

b. Transmitter not turned “ON”

c. Transmitter and receiver not both adjusted to the same

GROUP and CHANNEL

d. Receiver’s antenna’s are not installed

ANT LED is lit but NO audio a. Check that microphone is attached to transmitter, turned ON

and operating properly

b. OUTPUT switch is in the wrong position

c. OUTPUT connector cable is not installed or is defective

AF PEAK LED is always lit a. 500UDR is receiving a signal that is too strong. Move the

transmitter further away or reduce the transmitter’s output
