INPUT JACK

The 5-pin input jack accommodates virtually every lavalier, hand-held or shotgun microphone available. Use a

Switchcraft TA5F connector on the 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.

“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 “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 battery. As the battery voltage drops during use, the LED brightness will also

decrease. When the LED is barely visible, there will still be 30 minutes or more operating time remaining.

Since the internal circuits are all tightly regulated and the RF output stage has a separate discrete regulator, the

transmitter will continue to operate to a battery voltage of 6.5 Volts. From 6.5 Volts to 6 Volts, the transmitter will still

operate, but with degraded performance. Please note that a weak battery will sometimes light the POWER LED

immediately after turn on, but will soon discharge to the point where the LED will go out, just like a flashlight with

“dead” batteries.

The combination of an accurate battery condition indicator and regulation of all internal circuits provides much longer

battery life, as well as consistent performance over the life of the battery.
