ABOUT RADIO RECEPTION

Model RM103A is designed to synchronize its calendar clock automatically once it is brought within range of the radio signal from the U.S. Atomic Clock. When the unit is new and just out of the box, synchronization with the U.S. Atomic Clock can take up to 72 hours. When the unit is receiving the signal, the Radio Reception symbol will start to blink. Generally, complete reception takes around 2 to 10 minutes depending on the strength of the radio signal.

To disable the reception of RF signal manually, press and hold the DOWN button for 2 seconds until the Radio Reception symbol disappears.

To enable the reception again, press and hold the UP button for 2 seconds. The Radio Reception symbol will blink and the unit will search for RF signal automatically.

Interference

Reception can be affected by a number of factors. For best reception, place the device away from metal objects and electrical appliances. Other causes for signal interference include electrical power transmission towers, steel reinforced concrete construction, and/or metal siding.

Note:
Radio Frequency clocks perform best when placed near a window. After receiving the initial signal, updates are accomplished with greater ease. Even though there are areas that may have more difficulty in receiving a signal, the Atomic Clock contains a very accurate quartz movement and will retain precise time even if a signal is missed on a rare occasion.

HOW TO SET YOUR TIME ZONE
