2. To rotate the bar: pull the bar partway out of the socket, turn it 90°, and re-insert it in the new direc-
tion.
3. To move the bar from left to right push the bar back toward wallstand column and move to the

CAUTION
This bar is a hand rest only and is not intended to support a person’s full weight. To
avoid falls and potential injuries, do not hang or pull on the bar.
CAUTION
If the patient pulls on the lateral bar with enough force, the locks may release and
the receptor will lower slowly.
CAUTION
Use care not to drop lateral bar when handling. Place on accessories holder when
not in use.
CAUTION
Remove the lateral bar at the minimum receptor height, as you feel ergonomic.Do
not have the later bar installed if you want to move the receptor to maximum
height, unless your ceiling is high enough.
Ion Chambers
Photo-timing is controlled using three ion chambers similar to the device used in conventional radio-
graphic systems.
The Optima XR646 wallstand receptor may be equipped with an additional AEC ion chamber. The fourth
chamber is more effective when the receptor is used horizontally under a mobile table accessory
(Extended arm option).
Refer to
Chapter 10: Image Acquisition-Automatic Exposure Control (AEC) (p. 10-24)
for more informa-
tion about AEC exposures and ion chamber selection.
Note:
The following figures are for illustrative purposes only and do not represent true scale.
The ion chambers are round with the fourth chamber shown on the wallstand as a dashed outline
