INSTALLATION

Your CES Model 600L DTMF Encoder microphone may be easily configured for the
particular application. Power is supplied to the microphone through the radio's
microphone connector for all functions, including: audible sidetone and keypad
illumination.

If the Model 600L microphone was ordered for a specific application, a mating
connector is installed; or, an appropriate connector may be installed using the
information supplied below:

Cable Wire
Color

BLUE +12 VDC Input
RED Push-To-Talk (logic low)
WHITE TX Audio Output
BLACK CTCSS Hang Up (logic low)
SHIELD Audio/Logic Ground
YELLOW Logic and Power Ground

CTCSS Hang Up (Monitor) is a logical function that will normally (as shipped) provide
an off-hook (open-circuit) to the radio for CTCSS or DCS squelch "monitor" , or other
decoder functions, and a logic low when placed on-hook. A grounded microphone
hang-up clip is required.

Function

A CTCSS Inverter is available as a factory option that provides reversed logic from the
method described above. That is: the CTCSS Hang Up logic is an open-circuit when
on-hook, and a closed circuit (logic low) when taken off hook.
