User Manual
The LEDs located
on either side of the ‘STATUS’ LED indicate either selection information or optional Talkback
information.
Figure 2: MKU OCU
MKU dual pressure keypad OCUs normally send ON/OFF commands that activate programmed functions at the
target Cattron MCU.
All MKU OCUs are powered by a rechargeable Ni-Cad or disposable 3-volt alkaline battery packs.
In normal operation,
the ‘STATUS’ LED flashes green with each function command message and a beep is
sounded when a key is pressed.
When the battery voltage becomes low, the
‘STATUS’ LED flashes red and a beep sounds every ten seconds to
alert the operator that the battery pack needs to be replaced or re-charged.
The
‘STATUS’ LED can illuminate in a series of red blinking sequences to indicate a specific OCU fault, as
discussed in Appendix IV.
A belt loop strap is provided with all Cattron MKU OCUs. This is quickly and simply installed to
a ‘D’-ring located
on the curved underside of the controller. Referring to Figure 3, an optional shoulder-carrying strap is available on
request.
