4.3 Mounting and Removing the Control Head
Notice The control head contains devices which can be damaged by
static discharges. Always install or remove the control head in a static-
safe environment. For information on antistatic precautions, go to the
Electrostatic Discharge Association (ESD) website,
http://www.esda.org.
Mounting the
Control Head
The control head and its connection ribbon cable are delivered separately
from the radio body. Before installing the radio, the control head should be
mounted on the radio body.
The orientation of the radio body determines which way up the control
head is mounted on the radio body.
Notice It may be necessary to mount the radio upside down to main-
tain a gap of more than 3/8 inch (10mm) for air circulation between the
underside of the radio body and the mounting surface.
Notice When fitting the control head to the torso, be careful not to
pinch or squash the control-head ribbon cable.
1. Plug the control-head ribbon cable onto the control-head connector.
2. Place one edge of the control head on either the top or bottom pair of
snap features on the front of the radio body, then rotate to snap the
opposite edge into place.
