Power up the transceiver and select the desired operating frequency. Select AM, FM, CW, or PKT mode, and then key down to transmit a carrier Push and hold the TUNE button on the front of the Z-100Plus for one second (until the Tuning LED comes on), then release.
Includes 1 foot Icom and Yaesu 857/897 interface cable and 1 foot coaxial cable jumper. AN IMPORTANT WORD ABOUT POWER LEVELS The Z-100Plus is rated at 125 watts maximum power input at most. Many ham transmitters and transceivers, and virtually all amplifiers, output well over 125 watts. Power levels that significantly exceed specifications will definitely damage or destroy your Z-100Plus.
The tuner can be placed in bypass mode by pressing the Tune button momentarily. Although a DC coax jack is supplied on the rear of the Z-100Plus, the Z-100Plus may also be powered directly from internal AA or 9V batteries (not supplied); no separate power supply is needed.
Rear Panel The rear panel of the Z-100Plus features five connectors. Antenna connector: Connect the 50-ohm coax antenna feedline to this standard SO-239 connector. GND connector (wing nut): Connect to antenna system ground. Transmitter connector: Connect the 50-ohm coax jumper cable from this standard SO-239 connector to the ANT jack on the back of the transceiver.
INSTALLATION The Z-100Plus tuner is designed for indoor operation only; it is not water resistant. If you use it outdoors (Field Day, for example), you must protect it from the rain. The Z-100Plus is designed for use with coax-fed antennas. If use with longwires or ladder-line-fed antennas is desired, an external balun is required.

In order to install an internal battery supply, the lid of the Z-100Plus must be removed by first removing the four screws on the side of the case. Connection of the battery pack to the Z-100Plus is made via the two battery solder pads at J8 and J9.
When interfacing the Z-100Plus with an FT-857 or FT-897 using the Y-ACC cable, the Tune button on the Z-100Plus is used to initiate a tune. The Z-100Plus will automatically key the radio at the current power level during a tuning cycle and un-key when the tuning cycle is complete.

Be sure to use a vacant frequency when tuning. With today’s crowded ham bands, this is often difficult. However, causing interference to other hams should be avoided as much as possible. The Z-100Plus’s very short tuning cycle, as little as a fraction of a second, minimizes the impact of tuning transmissions.
