MEMORY RECALL FUNCTION ------- BLOCK MEMORY MODE
The Cal. 141 features a dual memory mode:
Single memory mode ..... The single memory mode is the default-set mode. The lap/split time data of one measurement from start to stop can be stored.
When the stopwatch is reset, and a new measurement is commenced, the lap/split time data of the previous measurement will
be automatically deleted.
Block memory mode ...... The block memory mode is an advanced mode designed for professional level use. A sequence of measurement data obtained
from start to stop (or reset) is recorded as a “block.” Up to 100 blocks of data can be stored in memory without deleting the
previous data.
<How to change the memory mode>
1. While in the TIME/CALENDAR display, press “B” 8 times until “BLOCK” appears on the display, above which either “ON” or “OFF” is flashing.
2. Press “A” for 1.5 seconds until the memory mode changes with a long beep.

Benefits of block memory mode
Easy data management ............ The block number as well as starting time and date of measurement are automatically recorded and stored.
Handy data storage ................ Creation of a new block of data will not erase the previous data in memory. While in the single memory mode,
a new measurement will delete the latest measurement data.

When the stopwatch is reset while the block memory mode is selected, a new “block number” is assigned to the next sequence of data.
Block number
A block of data with a block number is automatically accompanied by the starting time and date of measurement, which is convenient for easy data
management.
* A block of data contains at least three data components; block number, measured lap/split time(s), starting time and date. If more than one block of data is stored in memory, the memory may
reach a capacity limit even before the total number of lap/split time measurement totals to 300.
1. MEMORY RECALL WHEN THE STOPWATCH IS STOPPED OR RESET

BATTERY CHANGE
The lithium battery which powers your watch should last approximately 3 years. However, because the battery is inserted at the factory to check the function and
performance of the watch, its actual life once in your possession may be less than the specified period. When the battery expires, be sure to replace it as soon as possible
to prevent any malfunction. For battery replacement, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO SB-T74 battery.
* If the stopwatch is used for more than 3 hours a day, the battery life may be less than the specified period.
Battery life indicator
When the battery nears its end, a flashing battery mark “BATT” is displayed. In that case, have the battery replaced with a new one as soon as possible by the retailer
from whom the stopwatch was purchased or an AUTHORIZED SEIKO DEALER.
* When the battery is replaced with a new one, all the stored data will be erased from memory.
