Oregon Scientific JMR828A About Radio Reception, How To Set The Calendar Clock Manually

3. Replace the door so that it clicks into place.

Note: If not disposed of properly, batteries can be harmful. Protect the environment by taking exhausted batteries to authorized disposal stations.

Replace the batteries when the Low-batteryindicator lights up.

ABOUT RADIO RECEPTION

The JMR828A is a radio frequency (RF) controlled clock. When located within radio signal range from the U.S Atomic Clock , the clock time will automatically synchronize with time-signal transmission. The benefit of a RF controlled clock is that highly- accurate time is maintained and manual adjustments to the time and date are not required.

When the batteries are first installed, the JMR828A will automatically search for a radio signal.

When in search mode, the antenna icon [ ] will blink. This process takes between two (2) and (10) minutes. After initial search and synchronization with the Atomic clock, short periodic reception-signal scans will commence several times a day.

The antenna icon indicates the quality of reception.

RECEIVING

To deactivate the auto-reception of the radio signal, press and hold [ZONE] for 2 seconds and the antenna icon will disappear.

To enable this auto-reception again, press and hold [ ] for 2 seconds. The antenna icon will re-appear.

HOW TO SET THE CALENDAR CLOCK

MANUALLY

When the unit is outside of the radio signal generated from the U.S Atomic Clock, the unit may require manual setting.

Interference

Reception can be affected by a number of factors. For best reception, place the device away from metal objects and electrical appliances.

Note: Interference from sources such as TV sets can affect the signal. If, after batteries have been inserted for ten minutes, the radio signal is not received, then set the time manually (see section: How To Set The Calendar Clock Manually).

“SECONDS” AND DAY-OF-THE-WEEK

DISPLAY

The “second” and the day-of-the-week share the same section of the display.

Note: The RF controlled mechanism overrides manual settings unless auto-reception of radio signal is being deactivated. If manual settings are made, the clock will periodically adjust the time to what is indicated by the radio signal.

It is highly unlikely you should ever have the desire (or need ) to manually set the clock time, year, month or date of the JMR828A when it is within signal range of the Atomic clock.

However, in the event this becomes necessary please review the following.
