How to use CRONVI.

Upon first use, create a CRONVI account or log in with the existing one. When the device is online, CRONVI associates the archive with your account and synchronizes the available changes.

Before a race open Accounts and check the date until which offline use is permitted. The tender functions can thus continue to function even without network coverage within the indicated period.

Complete these checks a few minutes early and never while driving.

1. In Settings choose language, theme and audio profile.
2. Align theNow race to an official reference and verify the displayed fix.
3. Open Button, connect the Bluetooth command if you intend to use it and try at least one press.
4. Run Test audio and control your phone's media volume.
5. Open the race and check the program, durations, start mode, CO and average tests.

From My races select New race. For a trial session choose instead Training. Enter name, date and, optionally, a vehicle in the Garage.

You can add PCs manually or import a CSV program. From the race menu you can edit, duplicate, archive or delete the event.

The penalty rules entered in CRONVI are personal and must always be compared with the specific regulations of the event.

The first test, PC1, always starts manually by pressing START. For each subsequent PC you can choose:

Manual

At the end of the previous PC, press when you want to start the next one.

In time

The next PC starts automatically at the end of the programmed duration of the previous one.

Upon passing

The pressure that registers the previous step starts the next countdown at the same time.

The command Make all concatenated after PC1 applies timed start to all subsequent trials. Always check the mode shown under each PC's name.

Press START on the screen, on a compatible keyboard, or on the physical button. The large number shows the countdown of the current test; the smaller hour at the top shows the Race Time.

At each detection, press only once. The passage is saved immediately. From the menu you can cancel the last step, correct the reference from −99 to +99 cents, recover a missing step to zero or return to the race sheet.

To create a CO, indicate name, theoretical time, race day, reading to the full minute or exact second, lead and delay points and any maximum delay limit.

Opening Time controls, each line shows the status of the window and the last recorded step. When in transit, press Mark transit or use the physical button. CRONVI saves the time and calculates the estimated penalty.

The alignment of the race time is fundamental. The penalty shown is an estimate and does not replace the official data of the organizer.

Enter the total distance and one or more averages. The distances can be progressive from the starting point or represent the complete length of the individual sections. You can set the starting time or start the session manually.

• Calibrated distance
• Current average
• GPS speed
• Signal accuracy
• Deviation from theoretical time

Averaging changes are automatically applied to the programmed distance. Before START grant access to the precise location and wait for a stable GPS signal.

The phone's GPS is useful for training and estimation, but does not replace a calibrated or approved wheel probe.

Wait for the screen to indicate GPS acquired before leaving.

You can reset TRIP from the dedicated command or with the physical button. The plus and minus commands realign the distance to the road book using the pace chosen in the Settings.

To calibrate, drive an official stretch of at least 1km, pause and select Calibrate on the route. Enter the official distance and save the coefficient.

Voice

Spoken Countdown. The recorded voice is available in Italian.

Beep

Wordless signals, suitable for all languages.

Silent

No audible warning.

You can choose how many seconds to start the warning, activate the continuous beep at the end, the 30 second warning and the START beep. THE'Audio preview compensates for a perceived delay in playback. After each change use Test audio.

Saved steps shows each lap, bearings, discards and estimated passes. In Results you can insert the official times received from the organizer without modifying the originals.

From Archive and backup you can export races, tests, laps, results and settings to a JSON file. The import adds the races without deleting the existing ones; any duplicates become new copies. You can also import a PC program in CSV.

In the Garage you can save cars, photos and characteristics and indicate the main car. A car can be associated with races and training and remains in the session history.

Career calculate accuracy, consistency, balance and progression from real passes. You can set a personal mission, add achievements to your palmarès and unlock achievements.

CRONVI AI interprets the metrics and proposes a training session, without affecting the stopwatch or changing the readings. At least 10 measurements are needed for the first analysis; from 30 detections and with more sessions the profile becomes more reliable.
