One 3V Lithium/manganese dioxide battery is built in the device for real
time clock. Only trained personal should conduct battery replacement or
service. Incorrect replacement or service would result in a hazard.
3.4 Routine Inspection
Before each use, visual inspection on the whole device is recommended.
Check alarm signals before each use. Check alarm signals before each
use.Plug in mains supply, then switch on the product without pluging in
