the tuner can damage the unit.
WARNING:
In normal operation the DU 1500 L produces very high RF voltages and currents.We
do not recommend operation of this without the top cover securely installed due to the
danger of contact with high voltage.
Always be sure that a dummy load or antenna is properly connected when power is applied.
Voltages in excess of ratings can occur if no load is connected.

FRONT PANEL FUNCTIONS (Refer to page 3)
- Output (Antenna)
Continously adjustable input capacitor
- POWER/SWR METER
Dual needle meter displays FORWARD and REFLECTED Power in Watts. The SWR in measured where the two
needles intersecton the red scale.
- INPUT (Transmitter)
Continuously adjustable output capacitor.
- DIRECT-TUNED OUTPUT SELECTOR
Five-position rotary switch an output coaxial connector.
- TUNED COAX 1 selects the COAX 1connector trough the impedace matching circuit. - TUNED COAX 2 selects
the COAX 2 connector trough the impedance matchi circuit. - DIRECT BYPASS selects BYPASS COAX
connector by passing the
impedance matching circuit but provinding SWR, FORWARD and REFLECTED power meter readings.
- DIRECT COAX 1 select the COAX 1 connector bypassing the impedance matching circuit but providing SWR,
FORWARD and REF
LECTED meter readings.
