memory.
*Onepressonthiskeyinthismode interrupts data log-in with “PAUS” on
sub-displayforlogratere-setting.
* While data log-in performing, the “—” sub-display is blinking for storing
indication.
* When stores data at 40Kth (6Kth for 107N), data log-in stops, the bar is
full(for109only),sub-display keeps blinking “—” and showing FULL.
4.12.3 DATA LOG-OUT
* One press on PEAK H key (DATA LOG) enables data log-out function
whenisjustindatalog mode, sub-display appears sequence number
