The controls, display and an additional speaker are built into the microphone, allowing the transceiver to be hidden away.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat does the Instant Replay feature do?\u003c\/h3\u003e\n\u003cp\u003eInstant Replay allows previously received communications to be replayed. The UHF390R provides up to approximately 10 minutes of recording capacity.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs Instant Replay useful for 4WD touring?\u003c\/h3\u003e\n\u003cp\u003eYes. If you miss a convoy direction, road warning or other transmission because of cabin noise or distraction, you can replay the received communication rather than immediately asking the other driver to repeat it.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes the microphone have a speaker built in?\u003c\/h3\u003e\n\u003cp\u003eYes. The heavy-duty controller microphone includes its own speaker.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes the transceiver also have a speaker?\u003c\/h3\u003e\n\u003cp\u003eYes. The UHF390R uses a dual-speaker arrangement with audio from both the transceiver and controller microphone.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I hide the actual radio under the dashboard?\u003c\/h3\u003e\n\u003cp\u003eYes. That is one of the main design advantages of the UHF390R. The compact 27 × 102 × 85mm transceiver can be installed in a suitable concealed location while the microphone provides the user interface.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I mount the transceiver under the driver's seat?\u003c\/h3\u003e\n\u003cp\u003ePotentially, yes. The installation location needs to remain protected, securely mounted and suitable for the required power, antenna and microphone cable routing.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes the UHF390R have the full 80 UHF CB channels?\u003c\/h3\u003e\n\u003cp\u003eYes. It supports 80 Australian UHF CB channels, including 75 voice channels.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs this a full-power UHF?\u003c\/h3\u003e\n\u003cp\u003eYes. Maximum RF transmit output is specified at 5 Watts.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eHow far will the UHF390R transmit?\u003c\/h3\u003e\n\u003cp\u003eThere is no single accurate range figure.

The UHF390R supports duplex repeater operation with the standard +750kHz transmit offset.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes duplex automatically increase my UHF range?\u003c\/h3\u003e\n\u003cp\u003eNo. Duplex allows the radio to use a compatible repeater. It can provide much greater coverage where an appropriate repeater is within range, but provides no advantage if a suitable repeater is unavailable.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat antenna should I use?\u003c\/h3\u003e\n\u003cp\u003eThe radio requires a 50-ohm antenna system.

The UHF390R is specified for 10–15V DC operation, so a suitable 24V-to-12V conversion solution would be required in a nominal 24V vehicle.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWould the UHF400R be a better choice for a 24V truck?\u003c\/h3\u003e\n\u003cp\u003eIf direct 24V electrical compatibility is important, the UHF400R is better suited because its stated 10–30V operating range supports nominal 12V and 24V systems. The UHF390R is better suited where the controller speaker microphone, compact hidden transceiver and Instant Replay feature are the priorities.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eHow much current does the UHF390R use when transmitting?\u003c\/h3\u003e\n\u003cp\u003eThe specified transmit current consumption is approximately 1.7A with a 50-ohm antenna termination.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhat size fuse does it use?\u003c\/h3\u003e\n\u003cp\u003eThe specification lists a 2A fuse for over-current protection.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes it have reverse-polarity protection?\u003c\/h3\u003e\n\u003cp\u003eYes.
