GETTING TO KNOW YOUR IT-100

Your IT-100 is a quality, precision instrument that will give you many years of outstanding
service; take a few minutes to get to know it.
The IT-100 is designed specifically for use with Icom transceivers. Tuning is performed
when the TUNER/CALL button is pushed on the front of the transceiver and held for one
second. The tuner can be placed in bypass mode by pressing the Tune button on the front of the
IT-100 momentarily.
The IT-100 is powered directly from the radio interface cable; no separate power supply is
needed. The IT-100 automatically powers up at the start of a tuning cycle, and then goes into an
ultra-low-power sleep mode when tuning is complete. The latching relays hold the tuned
configuration indefinitely, even when DC power is completely removed. Tuning memories are
stored in FLASH memory.
The IT-100 has 2,000 frequency memories. When tuning on or near a previously tuned
frequency, the IT-100 uses "Memory Tune" to recall the previous tuning parameters in a fraction
of a second. If no memorized settings are available, the tuner runs a full tuning cycle, storing the
parameters for memory recall on subsequent tuning cycles on that frequency. In this manner, the
IT-100 "learns" as it is used, adapting to the bands and frequencies as it goes.

Front Panel

On the front panel there is one pushbutton and two LED indicator lights.
Tune Button: Initiates either a memory tune or a full tune, and also toggles the tuner
between "active" and "bypass" modes.
SWR LED: Lights or blinks to indicate SWR condition.
Tuning LED: Lights to give feedback on button presses, lights during tuning; gives tune
status at the end of a tuning cycle.
