The ExactSet (TM) feature of the RRM-112A will automatically

the US Atomic Clock when the product is in reception range of
the signal.
When the unit is receiving radio signal, the reception icon will start
to blink. The reception icon will show either strong, weak or no
signal depending on the strength of the radio signal. A complete
reception generally takes about 2 to 5 minutes.
When the reception is completed the reception icon will stop
blinking. The reception icon will show " " for no Reception or
" " for successful reception.
For best signal reception, place the RRM-112A away from other
equipment that emit RF or microwave signals such as TV's, radios.
PC's or microwave ovens. Other causes for signal interference include
electrical power transmission towers, steel reinfoced concrete
construction, and/or metal siding. Due to the density of other
signal broadcasts, the strongest signals are received between
midnight and 4 AM.
