Battery Information
The OCS2 is supplied with and powered by four (4) 9 VDC transistor type alkaline, non-
rechargeable batteries located behind the rear panel of the unit.
Battery Replacement
To replace the batteries, the rear panel of the OCS2 must be removed. To begin, loosen
the two thumb screws on the rear panel by rotating them counter clockwise. Once
unfastened, detach the rear plate from the unit by the thumb screws and place it
momentarily off to the side. At this point, the batteries and their receptacles will be
visible. Remove the four batteries by pulling them out from their holders (pull out at the
base of the battery). Replace the batteries with new ones observing polarity during
installation. To that end, push the battery leads into the correct polarity terminals and
guide the body of the battery completely into the holder. Replace the rear plate on the
unit and secure it with the thumb screws by aligning them to the body of the unit and
rotating them clockwise until fastened.
Battery Life
The Battery Level indicator provides the user with the approximate battery life
expectancy of the unit. Once all the LEDs are extinguished, the batteries should be
replaced immediately before further operation.
Notice
A full set of replacement batteries should be kept with the unit for field replacement.
Notice
To conserve battery life, turn the OCS2 power switch OFF when not in use.
Caution
Store the OCS2 in a cool, dry area. Remove the batteries from the unit if it is to be stored
for a long period of time.
Calibration and Inspection
Ojemann Cortical Stimulator (OCS2)
The OCS2 contains no user serviceable parts and requires no periodic calibrations.
However, a functional diagnostic should be performed on the device to verify all
stimulator parameters are within the manufacturer's specifications every six months or if
the device has been physically stressed (i.e., banged or dropped).
Call Integra Customer Service if service is required.
