3 Operating Instructions
3.1 OCU First Use
By removing the two screws for the battery cover, insert the AA batteries provided.
Referring to the figure below, battery access is under the cover on the rear of the OCU by the belt clip.

3.2 OCU to MCU Association
The Cattron-S series OCUs need to be paired with the MCU before first use, this is a simple procedure where the
MCU and OCU learns the others identity.
This process is called Association and can be carried out either directly or using CattronLink™
An OCU can only be used with the last MCU to which it was associated.
An MCU can only store the identities of eight OCUs, e.g. operating unit 1, spare 1, spare 2 etc. after eight
OCUs have been associated the OCU dis-association process must be followed before any new OCUs
can be associated.
A. To initiate the association process the MCU should be in Passive mode (not operating with any other OCUs.)
B. The OCU to be associated should be woken from sleep and in passive mode so the green status LED is
illuminated.
C. Preferably and if the MCU is accessible press and hold pushbutton 1 in the MCU at the same time as
initiating step D. If the MCU is not accessible make sure the OCU is as close to the MCU as possible and
certainly closer to the intended MCU than any other MCU. (
The logical association process is; MCU with
the button being pressed and/or the MCU with the strongest RF signal
).
D. Press and hold the On / Alarm button on the OCU for more than 10 seconds, the Status LED will turn Blue,
release the OCU ON/Alarm (and MCU button if pressed).
E. At successful completion of Association, the OCU status LED will revert to Green, if the association fails it
will change to Red and association should be re-tried.
Now press and hold the Stop button to turn off the OCU, turn it back on again and complete the Start sequence
so the Stop switch is flashing, then using the On/Alarm button verify that the correct MCU is being controlled.
