Batboard

I have a 900 MHz, 30 Watt, MSC2000 with CPS 2.03 CPS & Tuner.
I am trying to set the high and low power level setting with tuner.
I see 4 separate pages of transmitter level sets with soft tuning spots at different Freqs.
Can anyone tell me which settings are for the low power setting and which ones are
for the high power setting?

txpower1 = High Power and txpower4 = Low Power

Thank you.
