This table shows the variant resistor values and resulting voltages at TP_RFBAND for each
band.

Note: Voltages are calculated with a 3.30V (+/- 0.10V) reference from the power
supplies. If power section supports less than 3.30V, thresholds need to be adjusted.

Note: There is a dead battery lock voltage set at 2.30 Volts. If the transmitter is powered
on with a voltage of less than 2.30 Volts, the system will lock, forcing the user to either
recharge or replace the batteries. During the dead battery lock out, the battery gauge is
empty and the red led flashes.
