MAINTENANCE TYPE C (perform every year)
Note: The yearly maintenance actions, listed below, may be performed by the user in accordance with the procedures described in the E2 Lite Maintenance chapter.
| No. | Maintenance action | Remarks |
| 1 | Check battery valid date. | If the date is older than 4 years, replace battery as a preventative measure. See Image 13–51 for the location of the system battery. Note: When a new battery is installed, the user needs to place a sticker with the date on the inside of the metal plate (Bottom Panel) that indicates when the battery was last replaced. The absence of sticker means the battery has never been replaced. In this case the S/N sticker can be used for the reference date. |
