BATTERY REPLACEMENT
CAUTION: The replacement battery must be a CR2032 3 volt Lithium Coin.
When the internal 3 Volt Lithium Coin Battery falls below 2.75 Volts, the Low Battery symbol
( ) will appear in the lower left corner of the display indicating that the battery needs to be
replaced.
The procedure outlined below describes how to remove and install the battery and then
reconfigure the CRC

-25R Calibrator. Only qualified service personnel should perform this
procedure. If there are any questions, please contact Capintec’s only Authorized Service
Center at 1-800-227-6832.
The following question must be answered before proceeding with replacing the battery:
Since the Low Battery symbol appeared on the display, has the time reset to 00:00?
• If the answer is NO, then proceed to step 1 – Save System Data.
• If the answer is YES, then proceed to step 2 – Battery Removal.
1. Save System Data
a. If a printer is attached to the system, obtain a Diagnostic Printout by pressing
the MENU key, and then selecting the DIAGNOSTIC function. All stored data
will be printed. This information will be re-entered in steps 5 and 9 after the
new battery has been installed.
b. If a printer is not available, locate a copy of the original Calibration Sheet that
was supplied with the unit and record the following:
• Any new or changed Calibration Numbers,
• Any Container Correction Factors,
• Any User Added Nuclide information,
• The isotope information that has been stored for all of the User Keys
(U1-U5), and
• All Test Source information.
This information will be re-entered in steps 5 and 9 after the new battery has
been installed.
2. Battery Removal
a. Turn off the power switch on the back of the Readout Unit and disconnect the
power cord and ALL other cables.
b. Turn the console upside down with the keypad facing down. Locate the
rectangular access panel on the bottom of the readout unit. Remove the 3 flat
