Note:
It is only possible to measure the barometric pressure trend properly when
the unit remains at the same altitude. When moving around at different
altitudes within a short period of time, the air pressure and the barometric
pressure will change. The pressure trend will only be correct and regulate
the has remain at a constant altitude for 24 hours or more.
To recall recorded pressure history reading
The barometric pressure reading is recorded at an hourly interval and can be recalled
and displayed up to previous 12 hours.
Press “History” button (5) repeatedly to view pressure recorded in the past hours. “
-1
HR
” indicates the pressure of the previous hour. The pressure reading history will appear
for 20 seconds before the current pressure returns.
RCC Synchronization:
Where ever available, this clock will automatically synchronize with the radio control
towers at the following time: 02:05, 03:05, 04:05, 05:05.
User may also manually synchronize the clock by following the instructions below.
Press and hold down the
‘
- / RCC
’
button (3) for approximately 3 seconds until
is flashing.
When this signal is flashing, the clock is attempting to synchronize with the radio control.
will flash when a strong signal is received and the clock will synchronize with the
radio control. This process can take up to 7 minutes.
will stop flashing and will be
displayed once the signal is received and in synchronization.
will not be displayed if the clock is not able to synchronize within this period of
time. User may manually synchronize again at a later time or the clock will automatically
attempts to synchronize at the above mentioned time.
When the clock is attempting to synchronize, press down the
‘
- / RCC
’
button (3) to
cancel RCC synchronization.
Please note all other clock / weather station settings seize to function when the clock is
in RCC synchronization mode. Wait until the clock is no longer attempting to synchronize
or it is synchronized to set other clock and weather station function.
If the alarm goes off during synchronization mode, RCC synchronization will seize
immediately. Follow the above instructions again to set synchronization.
