Automatic Antenna Tuner mAT-705 V2.0 User Instructions

Thank you for your purchase of the model mAT-705 automatic antenna tuner, designed specifically for ICOM IC-705 HF/VHF/UHF transceiver. The mAT-705 tuner is powered by two built-in lithium batteries, can be charged by a USB power adapter. Magnetic latching relays are used inside the tuner to save energy.
The mAT-705 automatic antenna tuner responds to control commands from the IC-705 transceiver, providing micropro-cessor-based impedance matching on the 160 through 6 meteramateur bands.On the HF and 50 MHz bands the impedance matching range is from 5Ω to 1500Ω.
The tuner comes with control cable. Both ends of the control cable are standard 3.5mm plugs. One plug is connected to the TUNER socket of the transmitter, and the other  plug is connected to the CON socket of the tuner. The transceiver controls the tuner through this cable for automatic tuning. An RF cable mAT-RC1 that connects the IC- 705 and the tuner is sold as an accessory item. mAT-RC1 is a common coaxial cable with male BNC plugs at both ends.
