OPERATION:
Top Housing
A CK70 top housing includes the plastic housing, keypad, antenna(s), LED light pipe, and cell speaker. None of these items
can be individually replaced as they are bonded and heat staked at the factory in order to achieve the IP67 rating for the
product. The top housing must be replaced as a complete unit.
There are two styles of keypads that have been used to produce top housing assemblies. Original production used a
conductive puck style (shown at left in picture below). Current production uses a plunger style (shown at right in picture
below). Units should be repaired with the style of keypad they were built with. Do not swap a conductive puck style top
housing with a plunger style housing unless you are also replacing the keyboard PCB assembly to match it.
