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.

Charge
☆Two built-in 10440 lithium batteries, 3.7V, 350mAh.
☆TYPE-C USB charging cable.
☆Charging current is 500mA, about 1 hour.
☆Charging voltage is 4.5-5.5V.
☆The “PWR/CHARGE” red indicator light is on while charging. The red indicator
light will go out after the battery is fully charged.
☆When the tuner is being charged, the “PWR/CHARGE” indicator flashes red to
indicate that the lithium battery has failed. Please check the lithium battery
and replace it if necessary.
☆The “PWR/CHARGE” green indicator flashes when the tuner starts, means the
tuner’s battery needs to be charged.
Operating
☆The mAT-705 tuner has no mechanical power switch. Its startup and shutdown
are controlled by the IC-705 trans- mitter, which turns on and off along with
the transmitter.
☆Before use, make sure that the control cable and RF cable are properly
connected. Pay attention to whether the control cable has been inserted in
enough places.
★ Turn on the power of the IC-705 transmitter, the “PWR/CHARGE” of the mAT-705
tuner will auto matically light up in green. If this indicator flashes, it
means the tuner needs to be charged.
Start tuning cycle method A:
-
Enter the function menu of the transmitter, as shown in the figure, the [TUNER]virtual buttonsturns white to indicate that it is available.
-
When [TUNER] is displayed as “OFF”, press this virtual button, the transmitter will automatically control the tuner to start a new tuning cycle.
☆ When the tuner is tuning, it‘s “ONLINE- /TUNING”indicator lights up in red, and the red text “TUNE” will flash on the transmitter screen.
☆ After the tuner completes this tuning cycle, it is ON, the [TUNER]virtual button will display “ON”. The white text “TUNE” will always be lit on the transmitter screen, except for the”ONLINE/TUNING” indicator on the front panel that lights up green. -
When the [TUNER]virtual button is “ON”, press the virtual button again and it will turn “OFF”. At this time, the tuner will be turned off, and the tuner’s RF and ANT scoketwill be directly connected.The tuner will no longer have a tuning function.
Start tuning cycle method B:
☆ If the “PTT TUNE” function of the transmitter is activated, when
transmitter‘s PTT is pressed for the first time on a new frequency, the tuner
will automatically start a new tuning cycle.
★The “PTT TUNE” function of the IC-705 transmitter is turned on by default.If
you turn off this function, you will not be able to drive the tuning cycle by
this method. For more information about this function, please read the user
manual of the transmitter.
