INPUT JACK
The input on the UM195 accommodates virtually every lavalier, hand-held or shotgun microphone available. Use a
Switchcraft TA5F connector on the cord. See the separate sheet titled "UM195 Input Jack Configuration"
regarding the correct connections for various microphones, and other sources.
ON/MUTE/OFF SWITCH
Turns the battery power on and off. The center position is an "audio mute" which should be used when setting the
MIC LEVEL control to turn off the sound from the microphone during this adjustment. Even when the switch is
turned off or on aburptly, the pilot tone muting system prevents "thumps" or transients from occurring.
"ON" LAMP
Glows brightly when the battery is good. A weak or dim lamp means that the battery is weak, and has about half
an hour of operation left. If the lamp fails to light, the battery should be replaced. The power lamp should light up
in both the "MUTE" and "ON" positions of the POWER/MUTE SWITCH.
The "ON" lamp is connected to a precision battery test circuit that continuously monitors battery voltage. The LED
is at full brightness with a new 9 Volt alkaline battery. As the battery voltage drops during use, the LED brightness
will also decrease. After about 10 hours on the VHF version (7 hours on UHF version) the battery voltage will be
about 7 Volts and the LED will be completely out.
