Marconi H4855 is a Personal Role Radio (PRR) that allows users to communicate with each other over short distances. It features 15 channels, an adjustable volume, and a PTT (Press-To-Talk) button for transmitting messages. The device also supports a wireless PTT (Press-To-Talk) remote, which can be used to activate the PTT function without having to hold the radio itself. To set up the wireless PTT, simply switch off the PRR, connect the headset, insert batteries, set the channel selector, and switch the PRR on. Then, with the wireless PTT facing you, align the end labeled 'PROGRAM' with the raised feature below the PRR PTT switch. Switch the PRR off, position the wireless PTT as shown, switch the PRR on, and press and hold the wireless PTT until ascending tones are heard again. Release the PTT, and if ascending tones are heard again, the affiliation is successful.
