Operating your Z-100A tuner
When tuning an antenna is not required, there is no need to disconnect anything. Instead,
the tuner can be placed in bypass mode by pressing the Tune button on the front of the Z-
100A momentarily.
The Z-100A automatically powers up at the start of a tuning cycle, and then goes into a 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 Z-100A has 2,000 frequency memories. When tuning on or near a previously tuned
frequency, the Z-100A 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 Z-100A “learns” as it operates, adapting to the bands and
frequencies during use.
