The handset can be exchanged while the ignition is
ON or OFF.
It is strongly recommended you do not exchange the
handset while the vehicle is ON. You will be required
to conduct a breath test which may distract your
attention from the road.

exchange handsets when the vehicle is parked and the
ignition is OFF. To replace the handset while the
ignition is OFF, simply unplug the old handset and
plug in the new one, as described below.
