HOW to USE
FORWARD POWER MEASUREMENT
1.Set the function switch 2 to the "ON"
2.Set the function switch 6 to the "WATT"
3.Set the function switch 5 to the "FW"
4.Set the radio transceiver to transmit and read the scale corresponding to the Power range selected switch
(12W, or 120W)
REFLECTED POWER MEASUREMENT
1,Set the function switch 2 to the "ON"
2.Set the function switch 6 to the "WATT"
3.Set the function switch 5 to the "RW"
4 Set the radio transceiver to transmit and read the scale corresponding to the Power range selected switch
(12W, or 120W)|
VSWR MEASUREMENT
Step 1
1. Set the function switch 2 to the "ON"
2. Set the function switch 6 to the"SWR" , .Set the function switch 5 to the "CAL"
3. Set the radio transceiver to transmit mode.
4. Slowly turn the CAL control Knob clockwise until the meter point is at the "CAL"
position. This should be full scale.
Step 2
Set the function switch 5 to the ‘SWR’ position while transmitting. The meter will now indicate the SWR ratio.
Note: that the front and rear panel data of the two models are different.Subject to change without prior notice
CAUTION
1.5 -> 2.0. Your antenna is acceptably tuned and should work fine.
2.0 -> 3.0. Your SWR reading is slightly high, it shouldn't damage your radio
but you should try and tune your antenna to bring down your SWR reading.
Above 3.0 or more . Your antenna isn't tuned acceptably and could damage your
