INSTALLATION
To install the RX-200/400 and RX-600 simply connect coaxial cable directed to the antenna connector marked “ANT”,
and the cable coming from the transmitter or from the linear amplifier to the connector marked “TX”.
RX-200/400 and RX-600 are now ready to operate.
POWER MEASUREMENTS
1 Select the RANGE (3) switch on the end-scale position value as to the power of the unit.
2 Select the FUNCTION (4) switch in the power position.
3 Select the POWER switch the FWD position to measure the direct power (from the radio to antenna)
or REF position to measure the reflected power (from antenna to the radio).
4 Select the power value can be read on the corresponding scale.
