CLOCK BATTERY REPLACEMENT
To install the two new baeries, reverse the removal procedure:
1� Connect the red wire to red terminal on the le baery and slide the baery onto the tray.
2� Aach the blue wire to the black terminal.
3� Insert the second 8Ah baery and connect the blue wire to the red terminal.
4� As you slide the baery onto the tray, connect the black wire to the black terminal on the right
baery. See “Figure 52. New DC Baery Replacement” on page 177�
If you have diculty removing the
baeries through the access hole,
an oponal method for baery
replacement is to remove the
control box. Four Phillips-head
screws secure the control box to
the chassis. Remove the screws and
remove the control box to access
the baeries. Be careful that you
do not inadvertently disconnect
the control box wire bundles. An
assistant for this alternave method
of baery removal/replacement is
highly recommended. See Figure 53.
Clock Baery Replacement
A lithium coin baery supports the clock so the date and me is retained even when the main power is
turned o. (See Figure 54.) Replace the baery about every ve years (or as needed) with a DL 2025,
DL 2032, or CR 2025, or CR 2032 baery.
