Battery Replacement
When the display flashes the warning
"LOW BATTERY" , a new battery should be installed to
eliminate memory loss in case of power failure.
NOTE : The RAM battery backup circuit is designed to avoid loss of memory if the proper
procedure is followed when changing the battery.
The two key elements in this procedure are: (1) actual time spent in changing the battery and (2)
keeping the battery holder positive tab from touching the negative contact on the inside of the
holder. If the tab is kept isolated from the negative terminal of the holder, changing time is
extended to approximately 30 seconds. However, if the tab is allowed to short against the
negative terminal, this time is reduced to approximately 10 seconds. Therefore, if it is at all
possible, care should be taken during this procedure to hold the tab away from the negative
terminal.
1.
With the power cord unplugged from the wall outlet, remove the back cover.
2.
Carefully remove the battery by lifting up on the holder tab that keeps the battery in
place. Care must be taken in this procedure to prevent damage to any of the
surrounding components.
3.
Replace with Duracell #DL2450 lithium coin cell. These are often available at local
hardware or electrical supply stores. They can also be obtained from your RC1000A
distributor.
AS YOU INSTALL THE NEW BATTERY BE SURE THAT THE POSITIVE SIDE IS
FACING UP AND IS IN DIRECT CONTACT WITH THE HOLDER TAB.
4.
Replace the back cover.
5.
Plug the unit back in and turn the power on. Check to see if the memory is still intact. If
not, it will be necessary to reset the limits and reprogram the memory. Refer to Section
6-5, LIMITS Mode, and 6-6, SET Mode.
