Now, install 4 AA alkaline batteries, being careful to observe correct polarity. Reinstall the
lid, and reinstall the four screws to secure the lid. Never operate the Z-817H with the lid off, as
hazardous and potentially lethal RF energy is present while transmitting.
Compatible Transceivers
Although the Z-817H is designed to work with any radio / amplifier combination, the CAT
1
interface allows additional automation of the tuning process with compatible transceivers. The Z-
817H CAT radio interface cable is designed to be used ONLY with the following Yaesu
transceivers:
•
FT-817
•
FT-817ND
WARNING: Do not attempt to use the Z-817H’s radio interface cable with any other
transceivers, even if the CAT plug fits. At best, the Z-817H simply won’t work with these radios.
At worst, it could cause damage to the Z-817H, the radio, or both. If using the Z-817H with
another radio, do not hook up the included CAT cable.
Interface Cable
The Z-817H is supplied with a radio interface cable. Each end has an 8-pin mini-DIN
connector. The end with a round 8-pin mini-DIN connector goes to the radio, and the other end
goes to the tuner.
1 CAT - Computer Assisted Transceiver, a serial communication protocol allowing external devices to control certain Yaesu radios.
