Connect the 50 Ohm Dummy Load and Inline
Wattmeter to the ANT jack.
Connect the AF Generator to pin 4 of the MIC
jack, and adjust the AF Generator output level
to 0.5 mV @1 kHz.
Referring to the Table below, press the [ ALARM ] /
[ 2128 ] key to recall each parameter listed, then
key the transmitter (connect pin 3 of the MIC jack
to GND) and rotate the CH knob for the required
output.

Connect the 150 Ohm Dummy Load (or three 50
Ohm Dummy Loads in parallel) to the ANT jack.
Referring to the Table below, press the [ ALARM ] /
[ 2128 ] key to recall each parameter listed, then
key the transmitter (connect pin 3 of the MIC jack
to GND) and rotate the CH knob just to the point
when the S-meter reading is changed from S-7
to S-8.

SWR A
Connect the 150 Ohm Dummy Load (or three 50
Ohm Dummy Loads in parallel) to the ANT jack.
Press the [ ALARM ] / [ 2128 ] key to recall the pa-
rameter "1_SWR3."
Key the transmitter (connect pin 3 of the MIC
jack to GND), then press the [ ENT ] key.
Press the [ 2128 ] key momentarily to recall the
parameter "2_SWR3."
Key the transmitter (connect pin 3 of the MIC
jack to GND), then press the [ ENT ] key.
Press the [ 2128 ] key momentarily to recall the
parameter "3_SWR3."
Key the transmitter (connect pin 3 of the MIC
jack to GND), then press the [ ENT ] key.
This completes the internal alignment routine.
To save all settings and exit, press and hold in the
[ ENT ] key for at least one second.
To exit without saving, press the POWER key.
