SFA7700 CMOS and Backup Battery Replacement Instructions | 2
Several steps can be taken to minimize the possibility of electrostatic damage to the hardware:
•
Set the controller on an anti-static mat.
•
Before opening, put the included anti-static strap on the wrist and connect the grounding
wire to the chassis frame.
•
Rest the entire palm on the metal casing of the controller for at least three seconds.
•
Limit physical movement during the procedure to prevent possible buildup of static charge.
•
Avoid coming into physical contact with any other components within the controller casing
except for those being replaced or those that require removal to facilitate the battery
replacement.

:
If the directives above are not observed, damage from electrostatic charge may
not be immediately obvious, but can affect the correct operation of the system
later.
Receiving Inspection and Shipping
Take care when opening the shipping box containing the battery kit. Avoid the possibility of cutting
into the batteries with a box knife or razor.
Upon removal of the batteries, perform a visual inspection of each battery looking for tears, dents,
punctures, rips, leaks, or burns. If any damage is observed or suspected, repack in the shipping box
and contact DDN Support for return instructions and a new replacement.
Storage Recommendations
Replacement batteries should be installed as soon as possible following receipt. If immediate
replacement is not possible the following guidelines should be followed:
•
Once unpacked, do not stack batteries (backup battery packs)
•
Do not damage the battery’s heat shrink cover (backup battery packs and CMOS batteries)
•
Keep the batteries in a cool, dry place at normal room temperature (backup battery packs
and CMOS batteries)
•
Do not store in a refrigerator or freezer (backup battery packs and CMOS batteries).
The Battery Kit
The battery replacement kit includes the following items:
•
1 battery backup pack
•
1 CMOS coin cell battery
