3.2. INSULATION RESISTANCE TEST
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with ohmmeter between the jumpers AC plug and each exposed metal cabinet part, such as

3.3. BATTERY CAUTION
Danger of explosion if the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by
themanufacturer. Discard used batteries according to following caution:
Disposal or transportation of lithium batteries should be performed by permitted, in accordance with federal, state and
localguidelines.
A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in
strongpackaging.
Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their
ultimatedisposition. This is a good practice for all types of commercial or industrial waste.
When the lithium battery is exchanged, the clock settings are cleared. In this case, make clock settings again.
