INPUT JACK

The input jack on the UM700 is a Switchcraft TA5M connector that accommodates virtually every lavaliere, hand-held

or shotgun microphone available, with positive or negative bias. The input will also cleanly handle line level signals

up to 300 mV before limiting. Use a Switchcraft TA5F connector on the microphone cable or input adapter cord .

See the separate sheet titled “Transmitter 5-Pin Input Jack Wiring” regarding the correct connections for

various microphones, and other sources.

ON/OFF SWITCH

Turns the battery power on and off. Even when the switch is turned off or on abruptly, the digital muting prevents

“thumps” or transients from occurring.

“ON” LAMP

Glows green when the battery is good and the ON/OFF switch is ON. The lamp will glow yellow/orange as the

battery voltage drops and finally glows red when there are about 30 minutes of operation left (with an alkaline

battery). The lamp will flash red when there are only a few minutes of life left. A NiMh battery will give little or no

warning when it is depleted. If you wish to use NiMh batteries in the UM400, we recommend trying fully charged

batteries in the unit, noting the length of time that the batteries will run the unit and in the future use somewhat less

than that time to determine when the battery needs to be replaced. A weak battery will sometimes light the POWER

LED to the “good” green indication immediately after being put in the unit, but will soon discharge to the point where

the LED will go red or shut down, just like a flashlight with “dead” batteries. If the lamp fails to light, the battery

should be replaced.

FREQUENCY ADJUST (located under the sliding door)

These two rotary switches adjust the center frequency of the carrier. The 1.6M

is a coarse adjustment and the 100K is the fine adjustment. Each transmitter is

factory aligned at the center of its operating range. The default position of the

frequency select switches is in the center of the transmitter’s range.

AUDIO LEVEL CONTROL

Used to adjust the audio input level for proper modulation.
