Names and Functions
1 ANT IN (antenna input) A/B terminals
Use to connect the antenna for wireless tuner. When
installing the tuner unit, connect the optional UHF
antenna WRU-801A/WRU-806A.
As these terminals output DC power of 9V for the
booster inside of the connected antenna, connection of
any antenna other than stated above may cause bad
performance or a malfunction.
(the max supply current is 20 mA)
Note
Before locating and connecting the antenna, read carefully the
instructions supplied with the antenna.
Incorrect location of the antenna may cause a bad reception
such as intermittent sounds. If it is not easy to relocate the
antenna after location, check carefully if the performance will
be satisfied with the location.
Use the coaxial cable of impedance 50 ohms/75 ohms (5D-FB,
5C-2V, etc.). The cable can be extended up to about 50 m with
5D-FB, and up to about 25 m with 5C-2V.
2 Tuner unit slot (MIC1, MIC2)
These are for installation of the optional 800MHz
wireless tuner unit WRU-801A/ WRU-806A. Up to
two units can be installed. (Refer to page 9 how to
install.)
Before installation, read carefully also the instructions
of WRU-801A/ WRU-806A.
