Servicing
General
The 120EX pan and tilt head is robustly made to high engineering standards and little attention
is required to maintain serviceability except for regular cleaning. For service beyond regular
maintenance detailed in this manual, contact the OConnor headquarters or your local OConnor
representative.
Routine maintenance
Replace the electronic unit battery whenever the low battery indicator flashes.
During normal use, check the following:
Check the effectiveness of the pan and tilt locks. Reset as necessary - see Adjusting the
Lock Levers.
Check the operation of the balance mechanism digital display and the illumination of the
bubble level. Replace the battery if necessary - see Battery Replacement.
No other routine maintenance is required.
Cleaning
During normal operation the only cleaning required is a periodic wipe down with a lint-free cloth.
Any dirt that accumulates during storage or periods of non-use may be removed with a semi-stiff
brush. Particular attention should be paid to the dovetail faces of the camera mounting area.
Use out-of-doors under adverse conditions may require special attention and the head should
be covered when not in use. Salt spray should be washed off using fresh water at the earliest
opportunity. Sand and dirt act as an abrasive and should be removed using a semi-stiff brush or
a vacuum cleaner.
Battery replacement
The battery powers the digital display and illuminates the bubble level. It should be replaced
whenever the display flashes. The head requires a 9V PP3 battery (Lithium type).
1. Use a flat blade screwdriver to remove the three slotted screws in the battery cover
(Figure 5).
2. Remove the battery cover and place to one side.
NOTE: Use only detergent-based cleaners. DO NOT use solvent-based or oil-based
cleaners, abrasives or wire brushes to remove accumulations of dirt as these
will damage the protective surfaces.
NOTE: Replacement of the battery will not affect the calibration of the balance
mechanism display.
