Description

A complete three-piece mobile install pulled from fleet service. It powers on. It is NOT programmed, and I do not program radios. Read that before you buy.

Bench report

Functional
Powers on. Both the deck and the control head come up when power is applied, and the display lights. The control head was photographed powered up so you can see the screen for yourself. No transmit, receive, audio, or alignment testing was performed beyond that power-on check.
Cosmetic
Used fleet-vehicle condition. Light scuffs on the deck housing and the control-head bezel. All labels are present and legible, including the deck nameplate, which I photographed close up so you can read the model, serial, and FCC ID yourself. This deck wears the teal Harris badge rather than the silver one. A cosmetic badge variant, nothing more. Wants a wipe-down, nothing else.
Tested
Deck powered on 2026-08-27. Comes up with power applied · Control head powered on a bench supply and photographed. The display lights and every character is legible. The screen reads "WARNING! Lost MRU", which is simply the head reporting that no radio deck is attached: it was powered on its own for that photo, not wired to the deck. That is the expected message for a control head running standalone, not a fault. · Power cable present, intact, and mated to the deck · Harris hand mic attached on an intact coiled cord · Deck nameplate photographed and fully legible. Model, serial, FCC ID, IC all readable · All three pieces photographed individually plus a full bundle shot
Not tested
NOT PROGRAMMED. No codeplug loaded, and no programming service is offered with this sale · Transmit power and deviation NOT measured · Receive sensitivity NOT tested · Audio quality through the mic or speaker NOT tested · Alignment NOT checked and NOT performed · P25 or trunked operation NOT verified on any system · Speaker NOT audio-tested. Its leads are bare and unterminated
