3.21 EXERCISE TIMES
Exercise times may be set individually on a day by day
basis. Exercise periods can overlap day’s, i.e. if a time
is set for 11:55 pm Sunday for 20 minutes, it will turn
off at 12:15 am Monday.
The exercise period is globally programmable (common
to all days), and is limited from 10-119 minutes.
3.22 PUSHBUTTONS
(FIGURE 3.16)
3.22.1 UP ARROW
↑
The up arrow is used to step the time forward in incre-
ments of 1 minute. This feature has auto-acceleration
such that if the button is held on, the step frequency will
progressively increase to allow fast searching of a
required time. As soon as the button is released, it will
revert to normal speed.
3.22.2 DOWN ARROW
↓
The down arrow is used to step the time backwards in
increments of 1 minute. It also has auto-acceleration.
3.22.3 TIME (TIME/ALARM TOGGLE)
This toggles the display between normal current time
display and exercise time. When in exercise time mode
the following happens:
1. The colon stops flashing to indicate exercise time
mode.
2. The Sun LED flashes to indicate that it is initially
selected. The rate of flashing is either:
• 50/50% on/off to indicate exercise time is enabled.
• 90/10% on/off to indicate exercise time is not
enabled.
3. All other days that have exercise times enabled to
ON are indicated by LED ON, days that are disabled
are set to LED OFF.
If the display is inadvertently left in this mode with no
keyboard activity for more than 5 minutes, it will revert
back to normal (current time) display.
3.22.4 ON/OFF (ALARM SELECT TOGGLE)
When in exercise mode, this button will toggle the exer-
cise enable/disable status of the displayed day. The rate
of flashing will change as above.
3.22.5 DAY
The day button is used to step forward through the days
in either the current time or exercise time:
• In current time mode, the days will step through 7
states indicating Sunday to Saturday.
• In exercise time mode, the days will step through 7
states indicating Sunday to Saturday and will then
display state 8 - all days LEDs flashing on/off togeth-
er which represents the global exercise time period.
In this mode, the exercise period may be changed
using the up/down arrows as above but the on time is
limited to between 10 and 119 minutes.
