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 EC-200/EC-210 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. Note: When a new battery is installed, the user need to place a sticker with the date in the unit (on the rear of the chassis, near the Motherboard) 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. |
| 2 | Remove dust accumulation | Remove dust accumulation from the CPU fan on the motherboard with a few short bursts of compressed air. |
