# The remote

Press **F5** for the remote. It works like the real unit's.

## Buttons

| Button | Does |
|---|---|
| **LOCK / REL** | Locks or releases a speed on the active antenna. Plays the lock tone and calls out the antenna and whether the target is closing or moving away. FAST freezes the locked speed; TARGET keeps reading live |
| **ANT** | Switches the transmitting antenna, front ↔ rear. Only one transmits at a time, like the real unit. Also turns XMIT on |
| **XMIT** | Transmit on or off. The antenna has to be transmitting to see anything |
| **MOV STA** | Cycles Moving → Stationary Closing → Stationary Away → Bi-Directional |
| **SAME / OPP** | Lane mode for the current antenna: Off → Same → Opposite → Both |
| **FAST LOCK** | Turns the FAST window on or off. This is *not* a speed lock; use LOCK / REL |
| **SEN** | Detection range: 100 → 200 → 300 → 400 → 500 |
| **PS** | Lowest patrol speed that shows in the patrol window |
| **TEST** | Runs the self-test (about 6 seconds, ends in `PASS`) |
| **VOL** | Volume: 25% → 50% → 75% → 100% |
| **BLANK** | Blanks patrol speed while a lock is held |

LOCK / REL works whether FAST LOCK is on or off. With it on, the lock grabs a faster second vehicle if there's one in the beam; with it off, it locks the TARGET speed.

Display brightness isn't on the remote: it's in `/seeker_settings`.

## Stationary modes

| Mode | Shows | Reads |
|---|---|---|
| Moving | ` []` | Normal patrol: targets while you drive |
| Stationary Closing | `SC` | Only traffic coming towards you |
| Stationary Away | `SA` | Only traffic moving away |
| Bi-Directional | `S_` | Traffic either way |

The three stationary modes need the patrol car parked and never show a patrol speed. A car pacing you has no clear direction, so SC and SA skip it; S_ still reads it.

## The display

| Window | Shows |
|---|---|
| **TARGET** | The main vehicle in the beam, always live |
| **FAST** | The fastest vehicle in the beam, if it's faster than TARGET. Holds the frozen speed on lock |
| **PATROL** | Your own speed |

**Arrows.** Each speed window has its own pair. Down: the car is closing on you. Up: it's moving away. Neither: it's pacing you. They show how that car is moving, not which antenna saw it; the FRONT and REAR icons tell you that.

## Doppler audio

The tone tracks how far the target is *above your own speed*, not the number on the display:

| Situation | Tone |
|---|---|
| Parked, target doing 75 | High |
| Doing 65, target doing 75 | Low: only 10 over you |
| Target pacing you, or you're faster | Flat |

So slowing down raises the pitch on its own. The tone always follows TARGET, never FAST.

`/toggledoppler` cycles **On** → **On (Stationary Only)** (cuts out as soon as you roll) → **Off**. It starts off.
