Note: During the time you press PTT to transmit, you may notice the power level indicator drop to a lower level and then return to a higher level once you stop transmitting. This is normal and merely indicates that additional power is required to transmit compared to that used during reception.
Alkaline Batteries and Radio Performance
If you use alkaline batteries for emergency purposes, note that the transmitting power output may suffer as the alkaline batteries become weak and near the end of their useful life. In such cases, you might not be able to transmit with a full
2.5watts of power. Replace the batteries with known fresh batteries to be sure, or switch to a fully charged Lithium Ion battery pack.
When the appears (Low Battery), or you hear the Low Battery alert tone sound, be sure to replace all alkaline batteries in use. Doing so removes any chance of degraded radio performance and operation that can occur toward the end of the batteries’ useful life.
