9.1 On-Board Battery Backup Replacement
The monitor is fitted with a battery backup for the real time clock function. Failure of the battery will
only effect the time (all parameters, settings and process data are stored electronically and is not
effected by a failed battery).
Fitted is a Lithium CR2032 battery. Under normal operating conditions, the battery should not require
replacement for at least 5 years. However, we advise the battery is replaced if the monitor has been
kept in storage or remained off power for more than 3 years.
The battery is located behind the main display panel. To access the battery, follow these steps.
1, Ensure the monitor is isolated or disconnected
from HAZARDOUS LIVE voltages before access.
2, Remove the four plastic caps located on the
corners of the display using a small flat bladed
screwdriver to reveal the screws.
3, Unscrew the four screws and gently lower the
panel. Take care as the display is connected to the
back board via a ribbon cable.
4, With the display panel turned over and hanging
upside-down by the ribbon cable (see photo right),
the battery can be located on the bottom left corner
of the display board. Disconnect the ribbon cable if
this makes access easier.
5, Using a flat bladed screwdriver, gently prise out
the battery and replace.
6, Return the display panel back to the enclosure (first reconnect the ribbon cable if disconnected),
and screw back. Refit the screw covers.
7, Reset the Monitor time as described in section 6.1.4 of this manual.
