BRAKE INTERLOCK ALARM
There is an optional alarm in the charging cradle that will sound when
the user drives away with the handheld undocked. To do this, the
charging cradle must be interconnected with a brake-line pressure
sensor and with the signal from the truck’s “Ignition ON/RUN” power
connection (please see the wiring diagram in the next page).
When the wiring is accomplished, the cradle will issue an alarm only
under the following conditions:
 The handheld is undocked from the cradle AND
 The Ignition is on AND
 The brakes are released.
To stop the alarm sounding, either replace the handheld in the cradle,
apply the brakes, or turn off the ignition.
