Maintenance & Care; Replacing The Lithium Battery - IRIS Net TPI-8 Owner's Manual

2.4 Maintenance & Care
TPI-8 and TPI-12 need only minimum maintenance and care. In case of light
contamination clean the unit with a clean, dry rag. To remove persistent dirt, use
a mild cleaning agent and a clean, soft, slightly dampened cloth only.
NOTE:
Do not use any abrasives, abrasive sponges, steel wool or sol-
vents like alcohol, acetone or petroleum ether for cleaning the
touch screen surface.

Replacing the Lithium Battery

The System's main board houses a Lithium battery (CR-2032). If, in the touch
panel's BIOS, the time is reset to the default value (SUN 01.JAN.2006), the
Lithium battery needs to be replaced.
In doing so, please proceed as follows:
1. Disconnect the touch panel from the power supply.
2. Remove the CompactFlash Card.
3. Open the unit by removing the screws as shown in the following
illustration.
