Radio Signal Reception
When in reception mode, the radio tower icon will appear on the main
display. The wave indicator shows the strength of reception.
The range is from 0 - 6 bars. 0 is the weakest and 6 is the strongest.
Both auto and manual reception is possible. Each reception session lasts
15 minutes at maximum. Auto reception takes place twice daily at
1:05 am and 3:05 am. Manual reception is activated by pressing and
holding until the radio tower icon is shown. To cancel reception,
press and hold until the icon disappears.
Interference
Reception can be affected by a number of factors. For optimal reception,
please note that:
• A minimum distance of 8 feet should be kept from any interference
source, such as TV sets, computer monitors, microwave ovens and etc.
• Reception might be weak within concrete rooms (e.g. basements,
superstructures, office buildings). In extreme cases, place the clock
close to a window.
• Some localities may be subject to severe atmospheric disturbances.
However, such interference usually weakens during the night.
A single daily reception is sufficient to keep the accuracy reading.
• If the alarm goes off during radio reception, the session will be
interrupted and restart after the alarm has stopped.
In the event that radio-controlled time reception is not possible,
you may set the time manually.
