Power Output Select
Each conventional channel and SmartNet/SmartZone and P25 Trunked system can be
programmed for high, low, or switchable power. If the High/Low Power option button or
menu parameter is programmed and selectable power is programmed on the current
channel or system, high and low transmitter power can be selected. All models support
high and low power. The low power level is typically 1 watt and the high power level the
rated power output of the radio (3 - 5 watts, depending on frequency band).

The new level is flashed in the display as either “High Power” or “Low Power”. If
selectable power is not permitted on the current channel, “Fixed Low” or “Fixed High” is
flashed and no change occurs. The selected power level for a channel or system is
permanent until it is manually changed again. The low power mode may be automatically
selected during a low battery condition (see Section 3.4.2, "Low Battery Indication").
