➢ To learn the tach signal

DRW-96

1. Start the vehicle with the key.

2. Within 5 seconds, press and

HOLD

the Pro-

gram switch.

3. The LED will light constant when the tach signal

is learned.

4. Release the Program switch.

➢ Tach threshold on/off

In most cases, this jumper can be left in the OFF po si tion. Some new

vehicles use less than 12 volts in their ignition systems. The unit may

have trouble learning the tach signal in these ve hi cles. Changing the

jumper to the ON setting changes the trigger threshold of the digital

tach circuit so it will work properly with these vehicles.
