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.
