7. Mounting
The Ex-Time 40 is hung on a suitable item by means of the metal strap on the back
of the clock. The clock must be securely fastened and it must be ensured that the
Ex-Time 40 cannot be accidentally dropped into zone 0. For electrostatic reasons,
completely isolated suspension - e.g. on a purely plastic wall - should be avoided.
8. Repair
Because a safety check is required after a repair, any repairs must be carried out by
the manufacturer or by persons or service centers authorized by the manufacturer.
9. Cleaning, maintenance and storage
- For electrostatic reasons, only use a damp cloth or sponge to clean the unit.
- Do not use any solvents or abrasive cleaning agents when cleaning.
- The battery should be removed from the unit during prolonged periods of storage.
- Do not allow storage temperatures to exceed or fall below the permitted range of
0 °C to +50 °C!
