6. Locate the battery in the corner of the top board (see Fig. 15). It is
held in by two plastic clips. NOTE THE POLARITY OF THE
BATTERY TERMINALS, AS SHOWN IN THE FIGURE.
VERY IMPORTANT: YOU MUST USE A CR-1/3N 3-V LITHIUM
BATTERY IN THE 4030. YOU SHOULD HAVE THE REPLACEMENT
BATTERY READY TO INSTALL AS SOON AS YOU REMOVE THE
EXISTING (LOW) BATTERY. ONCE THE EXISTING BATTERY HAS
BEEN REMOVED FROM THE 4030, YOU WILL HAVE ONLY
ONE
MINUTE TO REPLACE IT BEFORE CALIBRATION AND RUN-TIME
DATA ARE IRRETRIEVABLY LOST.
IF THIS DATA SHOULD BE LOST, YOU WILL NOT BE ABLE TO
RECALIBRATE THE 4030 IN THE FIELD, BUT MUST SEND IT BACK
TO THE FACTORY FOR RELOADING OF THE APPROPRIATE
ANALOG ALIGNMENT VALUES.
7. Using a small flat-tipped screwdriver, pry the existing battery out of
its clip socket. IMMEDIATELY INSERT THE NEW BATTERY INTO
THE SOCKET, BEING CAREFUL TO OBSERVE THE CORRECT
POLARITY OF THE TERMINALS. A backwards battery won't
damage the 4030, but it won't work either. Remember: you have
one minute to replace the battery before calibration and run-time
data are lost.
8. Align the dual-board assembly with the guide slots on the inside of
the 4030 case and reinsert the assembly all the way (if it is wrong-
side-up, you won't be able to insert it).
9. Replace the four rear-panel corner screws. As you screw down
the rear panel, the internal board connectors will automatically
engage with the front display assembly.
10. Reinstall the CLAMP SLIDES.
11. Reattach the rear-panel cables and power connector. Then
reactivate the 4030. YOU WILL HAVE TO CYCLE POWER
TWICE. The first time you turn on the 4030, the "LO bat" warning
will reappear. Simply turn the unit off and on once again.
