10. ANTENNA TUNER OPERATION (ADVANCED) Antenna switching setting when operating with Dualwatch You can connect a Transmit/Receive antenna to either ANT1 or ANT2 for the normal operation. However, if you want to use separate antennas for transmit and receive you need to set "RX-ANT," or if you want to add an external device, such as a filter/ pre-amplifier for receive you need to set "RX-I/O." To change the RX-ANT Connectors Type, touch [TYPE] on the ANTENNA screen, then select between "Connect Receive Antenna" and "Connect External RX Device." MENU » ANTENNA > TYPE If you switch the RX-ANT Connectors Type to the opposite type, (to "Connect External RX Device" or to "Connect Receive Antenna") the previous RX-ANT (or RX-I/O) memory settings for both the Main and Sub bands are cleared. The "RX-I/O" settings are limited according to the antenna connector setting (ANT1 or ANT2), as follows. (Example: Main band=ANT1, Sub band=ANT2) When the Main (ANT1) and Sub (ANT2) bands are set to different antennas, if you set RX-I/O to the Main band, and then you set RX-I/O to the Sub band, the previous Main band setting is forcibly cleared, and is displayed. Setting Main back to RX-/IO SUB is forcibly cleared, and is displayed. RX-I/O is set to ANT1. ANT2 is selected. RX-I/O is forcibly turned OFF. RX-I/O is set. Example: When both the Main and Sub bands are using the same antenna (Example: ANT1) and the RX-ANT Connectors Type is set to "Connect External RX Device," if the Main is set to RX-I/O, the Sub RX-I/O is forcibly set (temporarily) the same as the Main setting. Turning OFF the RX-I/O on the Sub band clears the RX-I/O settings for both the Sub and the Main bands. "RX-I/O" is set to both the Main and Sub bands. RX-I/O is set to ANT2 The Main and Sub bands are not forcibly set or cleared when the RX-ANT Connectors Type is set to "Connect Receive Antenna." If you turn OFF RX-I/O on the Sub band that was forcibly set by above operation, RX-I/O on the Main band is also forcibly turned OFF, and is displayed. RX-I/O is forcibly cleared. RX-I/O is OFF. 76
