The Tach–Timer requires only a connection to the vehicle battery supply,
the engine ignition system and the driver controls to operate as a standard
tachometer. For Tach–Timers that include a speed and odometer display,
you will also require a Stack ST670 or ST669 wheel speed sensor.
If your Tach–Timer includes the option to trigger lap times automatically,
you will also require a vehicle-mounted infra-red (IR) sensor and a track-
side IR beacon.
Refer to the following section of this user guide for instructions to install
the Tach–Timer.
Depending on the model you have chosen, your Tach–Timer may not include
some of the features described in this user guide.
