JUMBO RF WALL CLOCK

WITH INDOOR - OUTDOOR THERMOMETER

MODEL NO.: JMR828A

Instruction Manual

INTRODUCTION

Congratulations on purchasing the Jumbo RF Wall Clock with Indoor-Outdoor Thermometer (JMR828A).

The JMR828A is a multifunctional radio frequency (RF) controlled clock. It is designed to automatically synchronize its current

time and date when brought within range of the radio signal generated from the U.S Atomic clock.

Also, this unit displays outdoor and indoor temperature. Included in this package is a remote thermo-sensor. Place the

thermo-sensor in a sheltered outdoor location within a 100 feet

(30 meters) radius of the main unit and it will transmit outdoor

temperature readings to the JMR828A.

Note: The effective range may be limited by building materials and the position of either the main unit or the remote thermo-sensor unit. Try various set-up arrangements for best result.

Setting up the thermo-sensor unit:

1. Position the remote sensor within the signal transmission range of the main display unit. The maximum transmission range is 100 feet (30 metres).

2. Remove the screws of the battery door on the remote thermosensor unit.

3. Select display of temperature in either °C or °F using the °C/°F slide switch.

BATTERY INSTALLATION AND REMOTE

THERMO-SENSOR SETUP

Follow this step-by-step procedure for installing batteries and setting up the remote-sensor unit. Successful setup should ensure that temperature signals are properly received.

5. Replace the battery compartment door and secure its screws.

Note: Though the sensor is splash proof and is meant for use outside, it should be placed away from direct sunlight, rain, or snow.

Once the batteries have been inserted into the remote thermosensor unit, batteries can now be inserted into the main unit.

BATTERY INSTALLATION : MAIN UNIT

This unit requires two (2) UM-3 or “AA” size batteries for operation.

How to insert batteries into the main unit:

1. Press the door tab and click-open the door.

2. Insert the batteries strictly according to the polarities shown therein.

UM3 AA

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.

Note: [

] Low-battery indicator

Replace the batteries when the Low-battery indicator 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 highlyaccurate 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.

The day-of-the-week is displayed as an abbreviation in three languages.

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.

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.

To change the “seconds” display to the day-of-the-week display:

1. When the “seconds” are displayed, press [CLOCK] once.

To change the day-of-the-week display to the “seconds” display:

1. When the day-of-the-week is displayed, press [CLOCK] once.

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.

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.
