Transmit Power Adjustment - Interphase Advantage User Manual

To Adjust Transmit Output Power:
1) Press "PWR" Softkey to bring
up the Pop-Up Power Window
(as shown above).
2) Use large front panel knob to
adjust power to desired level.
(In above example, output
power is 70% = approx. 700
Watts RMS)

Transmit Power Adjustment

The Output power of the Advantage can be adjusted in 24
steps from low to high. Low power settings are suggested
for shallow depths with higher power suggested for deeper
depths. Each time the Advantage is turned on, the output
power defaults to a 50% value which is approximately 500
watts RMS output (4,000 watts peak-to-peak).
Output Power Adjustment
The output power can be adjusted at any time by pressing
the "PWR" softkey at the far left of the Control Center, as
shown at left. After pressing the "PWR" softkey a Pop-
Up Power Adjustment Window will temporarily appear.
Use the large front panel knob to adjust the power level to
the desired setting. The graphic adjustment chart is
calibrated to show the approximate percentage of full
output power. Full Output power is 1,000 watts RMS, so
70% (as shown above) would be equal to 700 watts rms.
The output power adjustment will affect both the 200 kHz
and the 50 kHz output regardless of which frequency is
selected for viewing. For example, even though the 200
kHz frequency is selected, if the power output is reduced to
50%, then the 50 kHz output power is also set for 50%.
The output power actually changes as the knob is rotated.
If the Chart (depth) view is behind the Pop-Up Power
Adjustment Window, you can watch the effect of changing
the output power. When the output power is at the desired
level you can remove the Pop-Up Power Adjustment
Window by either:
1) Not touching the adjustment knob for
10 seconds, or
2) Pressing the "PWR" softkey, or
3) Pressing any other softkey.
The output transmit power setting is automatically saved
whenever the Pop-Up Power Menu disappears.
