The life of the battery is 5 years at 25
°
C. If the battery is used at a higher temperature, its life is shortened.
Assignment of the battery error flag differs depending on the message output mode, as follows, where n =
100 + 10 x unit no:
In sentence mode: word n+5 bit 05
In phrase combination mode: word n+9 bit 05
When the ERR indicator is lit due to a low battery, replace the battery with a new one within 1 week.
