④
Mount a new battery module on the mount
base.
⑤
Connect a new battery cable to the new battery
module.
NOTICE
Be sure to replace the battery cable along with the battery module. The purpose
of this is to increase product reliability.
⑥
Push and hold the BATT.SET switch until the BATT.SET LED comes on. By doing so, you
can write the date and time of the battery replacement to the CMU module’s program storage
memory. During the write, the USER LED continues blinking (this is no error), indicating
that the write is in progress.
⑦
When the BATT.SET LED comes on, release the BATT.SET switch. This procedure ends
when the BATT.SET LED and USER LED are both lit.
CAUTION
The battery cable has to be wired in a power-on condition, so be sure to provide
protection against electric shock before you turn on the power to the CMU
module.
NOTICE
This hardware unit may malfunction if it is connected poorly or has a broken line.
After connecting the connector, check whether it is locked.
