What is the first step for operating the PRC-90-2 survival radio?

The first step for operating the PRC-90-2 survival radio is to fully extend the antenna. This is crucial because the antenna is essential for establishing a proper radio signal. Fully extending it allows the radio to receive and transmit signals more effectively, optimizing its performance. Without a fully extended antenna, the range and clarity of communications can be significantly compromised, which is particularly critical in survival situations where reliable communication can mean the difference between being located or remaining lost.

While turning on the device, selecting the emergency channel, and adjusting volume control are all important subsequent actions, they depend on the operational readiness provided by the properly extended antenna. Thus, beginning with this step ensures that the radio is ready for effective use right from the start.
