CAUTION: Make sure the SWR is less than 2:1 before using the radio. An SWR higher than 2:1 can damage the transmitter.
The PRO501HH can also use any type of 50 Ω / 27 MHz band
antenna. Although a telescoping antenna might provide better transmission and receiving, it is not as compact or easy to use as the antenna included in the package.

time, place the radio in the charge adapter. Let it charge for about 12 hours or until the LED on the charge adapter turns green.
Regardless of which type of batteries you use in this radio, the battery
icon ashes when power is low. Replace the alkaline batteries or
recharge the unit if using the rechargeable NiMH batteries.
Low Power Indication
The battery icon shows a reduced power level and its outline ashes. Connect the DC power cable to a power source and to the radio to continue to use it until you can recharge/replace the batteries.
