Notes: 1)	If no battery is used, only the fixed area is backed up (counters 16 points: C1008 to C1023, internal relays 128 points: R2480 to R255F, data registers 55 words: DT32710 to DT32764). When the optional battery is used, data can be backed up. Areas to be held and not held can be specified using the system registers. (Exclusive instructions allow writing and reading data in flash ROM.)
2)	The number of points can be increased by using an auxiliary timer.
3)	Precision of calendar timer:	– At 0 ℃ +32 ℉, less than 119 seconds error per month.
		– At +25 ℃ +77 ℉, less than 51 seconds error per month.
		– At +55 ℃ +131 ℉, less than 148 seconds error per month.
4)	An optional communication cassette (RS-232C type) is required in order to use 1 : 1 communication.
5)	An optional communication cassette (RS-485 type) is required in order to use 1 : N communication.
6)	An optional communication cassette (RS-485 type) is required. When the communication cassette is attached and it communicates, re-send processing is recommended.
