Low battery icons for display and sensor

Setup Information: The Temperature Sensor

uses 2 x AAA, IEC LR3, 1.5V

battery. To install and replace

the batteries, please follow

the steps that follow:

Position the Atomic

Clock and the Outdoor

Sensor five to six feet

apart with nothing

between them.

Insert batteries into the Wireless Outdoor

Temperature Sensor first - it is important that

you do not insert the batteries into the Atomic

Clock yet.

You must insert the batteries into the Atomic

Clock within 3minutes of inserting the

batteries into the Sensor.

Slide out the battery compartment lid at the

bottom of the Outdoor Sensor.

Insert the batteries into the Outdoor Sensor

first, observing the correct polarity (see

markings inside battery compartment).

Replace the battery holder on the unit.

Immediately after and within 3minutes, insert

the batteries into the Atomic Clock, observing

the correct polarity (see markings inside

battery compartment). Replace the battery

cover. The Atomic Clock uses 2 x AA batteries

( IEC LR6, 1.5V ).

The outdoor temperature and the signal

reception icon should be displayed on the

Atomic Clock. If this does not happen after 3

minutes, the batteries will need to be removed

from both units and re-inserted, following the

instructions above.

Note: In the event of changing batteries in any of

the units, all units need to be reset by following the

setting up procedures. This is because a random

security code is assigned by the Sensor at start-up

and this code must be received and stored by the

Atomic Clock in the first 3 minutes of power being

supplied to it

Note: If the signal reception is not successful on

the first frequency (915MHz) for 22 seconds, the

frequency is changed to 920MHz and the learning

is tried another 22 seconds. If still not successful

Page 4 of 12

the reception is tried for 22 seconds on 910MHz.

This will also be done for re-synchronization.

The Outdoor Temperature Sensor

Remote transmission of

outdoor temperature to

Temperature Station by

915 MHz

Shower proof casing

Wall mounting case

Mount in a sheltered

place. Avoid direct rain and sunshine.

Under the eaves of your home is an ideal

place.

Positioning the Temperature Sensor:

The Sensor is supplied with a holder that may be

attached to a wall with the two screws supplied.

The Sensor can also be positioned on a flat

surface by securing the stand to the bottom to the

Transmitter.

Note:

Before permanently fixing the Sensor wall base,

place all units in the desired locations to check that

the outdoor temperature reading is receivable. If

the signal is being received, the signal reception

icon will be displayed on the Atomic Clock. In

event that the signal is not

received, relocate the Sensor or

move it slightly as this may help the

signal reception. To ensure a good

connection, there should be a

distance of no more than 200 feet

between the final position of the

Atomic Clock and the Sensor.

To wall mount the Temperature Sensor:

1. Secure the bracket onto a desired wall using the

screws and plastic anchors.

2. Clip the remote temperature sensor onto the

bracket.

WWVB (Atomic Time) Radio signal:

The clock must receive the WWVB Radio

Signal to automatically set the time, date and

weekday.

The clock automatically starts the WWVB on

the top of the hour between the hours of 12:00

AM and 6:00 AM.

If this synchronization attempt is successful

the radio tower icon appears on the display.

About WWVB (Atomic Time) Radio Signal

Reception:

A continuously displayed radio tower icon

indicates that the WWVB signal was received

successfully during the last attempt. If the

clock attempts to receive the WWVB signal

and is unsuccessful, the tower icon will not be

continuously displayed on the LCD.

We recommend a minimum distance of 8 feet

(2.5 meters) to all sources of interference,

such as televisions or computer monitors

Radio reception is weaker in rooms with

concrete walls (e.g.: in cellars) and in offices.

In such environments, place the system close

to the window.

Daylight Saving Time

The National Institute of Standards and

Technology and WWVB encode a special DST

“bit” in the WWVB transmission for DST.

Your La Crosse Technology® clock will read

this information (only if "DST" is set to "On")

and automatically advance the time one hour

in the spring and back an hour in the fall.

Arizona and Indiana: If you live in an area that

does not recognize DST you must de-activate

Daylight Saving Time by setting "DST" to

"OFF"

See "Set Daylight Saving Time ON/OFF" on

page 6 for instructions.

Setting the Daily Alarms:

To turn the alarm on:

Press the "ALARM" button. The LCD will

display the alarm icon .

To set the Alarm Time - Hour: Press and

hold down the "ALARM" button for 2 seconds

until the hours digits flash. Use the “PLUS”

button to set the hour. Press the "ALARM"

button to confirm your setting and move to

setting the minutes.

To set the Alarm Time - Minutes: The

Minutes digits of the Alarm Time will flash. Use

the “PLUS” button to set the minutes. You can

hold the "PLUS" button in to speed up the

setting of minutes by using five minute

increments. Press the "ALARM" button to

confirm your minutes setting and to end the

setting procedure.

To activate or deactivate the daily alarms,

briefly press the “ALARM” button once. When

the alarm is active the clock displays the alarm

icon below the word "ALARM". When

deactivated, the alarm icon does not

display.

About the Daily Alarms:

After 30 seconds without pressing any button

the clock switches automatically from alarm

setting mode to normal clock mode.

The alarm will sound for 85 seconds if not

deactivated. You can deactivate it by pressing

any button. The alarm will be repeated

automatically after 24 hours.

The alarm uses 3 different patterns of tone,

beginning gently and increasing in intensity,

known as a "Crescendo Alarm". The effect is

to provide increasing levels of alarm to ensure

waking while providing a gentle alarm to

lighter sleepers.

Automatic Snooze function:

While the alarm is sounding, press the

"SNOOZE" button to activate the snooze

function. The alarm icon flashes on the

display until the alarm sounds again when the

Snooze period is over (10 minutes).

Page 9 of 12

When cleaning the display and casings, use a

soft damp cloth only. Do not use solvents or

scouring agents as they may mark the LCD

and casings.

Do not submerge the unit in water.

Furthermore, fix all parts in place where the

units are adequately protected against

moisture and rain.

Special care shall be taken when handling a

damaged LCD display. The liquid crystals can

be harmful to user's health.

Do not make any repair attempts to the unit.

Return them to their original point of purchase

for repair by a qualified engineer. Opening and

tampering with the unit may invalidate their

guarantee.

Never touch the exposed electronic circuit of

the device as there is a danger of electric

shock should it become exposed.

Do not expose the units to extreme and

sudden temperature changes, this may lead to

reduce their accuracy.

Batteries are the single largest cause of

customer support cases. Please use plain

Alkaline batteries testing no less than 1.48 on

a voltmeter or with and expiration date 7 years

in the future.

Battery Replacement

If you notice that the LCD appears faint or that

WWVB time reception is not working properly,

try a fresh set of batteries before contacting

customer support.

The Low Battery Icons:

When the batteries need to be replaced in the

Wireless Outdoor Sensor, the LCD will display

the “TX” icon.

When the batteries need to be replaced in the

Atomic Clock, the LCD will display the “RX”

icon.

We recommend that you replace the

batteries in all units regularly to ensure

optimum accuracy of these units. Please

see the battery life in the specifications

below.

Help us to keep our environment clean. Return

used batteries to an authorized depot.
