Please Note: It is recommended that unless the clock accuracy deviates by more than
34 seconds per year this facility is not implemented, manual adjustment of the time as
highlighted at the beginning of this manual should be applied.
DST Shift Time
To compensate for time changes across the seasons, the unit has the ability to
automatically adjust time (between GMT and BST for example).
The TU-8A can handle up to a 4 Hour change in time which can be adjusted as below,
the SPRING: time moves forwards and the FALL: time moves backwards.
From the home Screen press SET/SAVE until >SET DST SHIFT TIMES is displayed,
press ENTER.
Using the ENTER button gives access to the SPRING: setting, use the + or – buttons to
change time to the desired difference then press ENTER to jump to the FALL: setting,
setting, use the + or – buttons to change time to the desired difference then press SET/
SAVE.
The settings for UK should read as follows SPRING: 1AM
FALL: 2AM
Please Note: This facility will not become active until the DST Operation facility is
enabled, see the next section for how to activate this function. Do not use this function if
your area/region does not use the DST facility.
Set DST Operation
After the DST Shift Time has been set, you can then add Start and End dates for DST
operation.
Up to 10 entries can be stored in advance, so for example the TU-8A can store the time
changes for the next 10 years.
From the home Screen press SET/SAVE until >SET DST #1 is displayed, press ENTER.
Change the Year using the + or – button, then ENTER using the same procedure to set
the Month and Date, this is the SPRING date.
After setting the above the display jumps to another date, showing a Month and Date,
this is the FALL date, adjust as above.
Once happy with the setting press SET/SAVE and the TU-8A will jump to >SET DST #2.
This continues for up to 10 entries, it is up to the user how many of these are pre-set.
