MKU OCU
User Manual
Indicators
Referring to Figure 5, the OCU is a lightweight hand-held unit with twelve pushbuttons (function keys) on a single
keypad, plus a rotary ON/OFF switch and a push/pull STOP switch.
The OCU may be hand carried, held by a belt loop strap or worn with an optional shoulder-carrying strap. The
OCU is powered by a disposable (alkaline) or rechargeable (Ni-Cad) battery pack.

Note: An optional toggle switch may be fitted between the ON/OFF switch and STOP switch.
With the correct color-coded TransKey inserted into the OCU, setting both the STOP and ON/OFF switches to
their respective ‘OFF’ and ‘ON’ positions will apply power to the OCU.
Immediately after power has been applied to the OCU, if a good battery is installed, the
‘STATUS’ LED should
momentarily illuminate red, followed by orange, then ‘flash’ green. Two short beeps will also be heard. In addition,
any time a pushbutton (function key) is pressed, a beep will be heard and the
‘STATUS’ LED will ‘flash’ green
during a radio transmission.
When the battery voltage becomes low, the
‘STATUS’ LED will ‘flash’ red and a beep will be heard once every ten
seconds to alert the operator to change or re-charge the battery pack.
When the ON/OFF switch is set to the ‘OFF’ position, power is removed from the OCU causing all control
functions to cease.
Setting (pushing down) the red STOP switch to ‘STOP’ before setting the ON/OFF switch to
‘OFF’ immediately sends a stop command to the MCU.
Referring to Figure 5 above, all active function key (pushbutton) commands are identified using labels placed next
to each pushbutton. When a pushbutton is depressed, the OCU transmits the corresponding command (as
labeled). All pushbutton operations are momentary and must be maintained by the operator. Releasing the
pushbutton will send an ‘OFF’ command that de-energizes the corresponding output function.
