SOLAR TRANSMITTER OPERATION MODES

Important:

Users need to press the reset key to activate the solar transmitter

and link the transmission to the Solar Station (receiver).

It is important to allow sufficient light to reach the solar panel while

activating the solar transmitter. Make sure the lights are on in the setup

room and the solar panel is facing a 60W light bulb or brighter - do not

cover with hands or other objects.

Solar transmitter RESET key:

The solar transmitter has 3 operations modes:

Normal Operation Mode:

This mode occurs when the battery voltage is higher than 2.5V.

The transmitter will measure and transmit the temperature data to

the solar wall clock every 8 seconds.

The environment brightness is checked every 5 seconds

If a dark environment is detected, it will measure and transmit the

temperature every 16s.

Note: only use a small pointed pen to

press the RESET key to re-active the

transmitter into Normal Operation Mode.

many years of service. If your batteries need to be replaced, we suggest

you use 2 fully charged the AA Alkaline.

Rechargeable batteries should be fully charged before inserting into clock.

Alkaline rechargeable batteries must be used.

If you choose to use non-rechargeable batteries, the battery switch MUST

be moved to the BATTERY position (not the SOLAR position). In this

position, the solar cells do not charge the batteries.

REGARDLESS OF THE TYPE OF BATTERIES INSTALLED, THE

BATTERY SWITCH MUST BE IN THE BATTERY POSITION WHEN

THE BATTERIES ARE INSERTED.

If rechargeable batteries are used, the Battery switch should be moved to

the SOLAR position AFTER it is has been inserted.

To use non-rechargeable alkaline batteries:

1. Remove the included rechargeable AA batteries from the

compartment.

2. Use the switch to select the alkaline battery (see below).

3. Insert the batteries into the compartment, observing the correct

polarity (see marking inside battery compartment.

4. Replace battery cover

Note: For best performance, batteries should be replaced at least once

every 2 years to maintain the best running accuracy. Ensure that the

batteries used are new and the correct size.

Use switch to

select which type

of battery will be

used before

SETUP AFTER CHANGING/REPLACING THE BATTERY IN THE

SOLAR CLOCK

1. After powering up the Solar Clock, all LCD segments will light up

briefly and it will show the time (12:00), indoor temperature, date,

and indoor humidity.

2. After the batteries are inserted, the Solar Clock will start receiving

data signal from the solar transmitter. The outdoor temperature data

should then be displayed on the Solar Clock. If this does not happen

after 2 minutes, the batteries will need to be removed from both

units and reset from step 1.

3. The distance between the Solar Clock and the transmitter should

not be more than 330 feet (100m) (TBA) to ensure sufficient 915

MHz transmission. (see notes on “Positioning” and “915 MHz

Reception”).

Note: When changing the battery:

1. Be careful that it does not spring free from the contacts.

2. Press any button 20 times with the battery removed.

3. Always wait at least 10 minutes after removing battery before

re-inserting; otherwise start up problems may occur.

TO SET THE TIME

Note: the time will be displayed with “AM” or “PM”for the time from 12:00

until 11:59.

1. Press and hold the SET key for 3 seconds to enter the time setting

mode.

2. The hour digits will start flashing.

3. Set the desired hours by pressing and releasing the +key followed

by pressing the SET key.

4. Now the minute digits will start flashing.

5. Set the desired minutes by pressing and releasing the +key. If the +

key is held, the units will increase by 5.

6. Press the SET key again to confirm and enter the Solar Mode

setting.

SOLAR MODE

The Solar Mode is used for saving the power consumption of the

rechargeable battery (Default setting ON):

1. The characters “ON” or “OFF” will start flashing. By use of the +

key select “ON” or “OFF” to set the solar mode.

2. Press and release the SET key to exit the setting mode and switch

back to the normal display mode.

If the solar mode setting is ON:

The surrounding environment brightness is checked every 5

seconds

LCD will automatically turn OFF if the environment is too dark

LCD will automatically turn ON if the environment is bright

enough

No information will be displayed when the LCD is OFF, but all the

settings and operations will remain, except for the temperature

and humidity measurements.

If the solar mode setting is OFF:

LCD will remain ON constantly.

STOP MODE

If the Solar Clock is placed in a dark environment for 72 hours continually,

the clock will go to the stop mode:

The most power saving condition.

The Solar Clock will not perform any operation and the LCD will also

be OFF.

Users need to press any key to wake up the Solar Station and to re-

activate the transmission with the solar transmitter.

915MHZ RECEPTION CHECK FOR OUTDOOR SOLAR

TRANSMITTER

The Solar Clock will receive the outdoor data every 48 seconds. If the

temperature data is not being received 2 minutes after setting up (or the

display shows “- - -”), then please check the following points:

1. The distance of the Solar Clock or outdoor transmitter should be at

least 6 feet (2 meters) away from any interfering sources such as

computer monitors or TV sets.

2. Avoid placing the receiver onto or in the immediate proximity of

metal window frames.

3. Using other electrical products such as headphones or speakers

operating on the same signal frequency (915MHz) may prevent

correct signal transmission and reception.

4. Neighbors using electrical devices operating on the 915MHz signal

frequency can also cause interference.

Note: When the 915 MHz signal is received correctly, do not re-open the

battery cover of the Solar Clock, as the batteries may spring free from the

contacts and force a false reset. Should this happen accidentally then

reset all units (see “TO INSTALL / REPLACE BATTERY IN THE SOLAR

CLOCK” and “INITIAL SETUP”above) otherwise transmission problems

may occur.

The maximum transmission range is 330 feet (100 m) (TBA) from the

outdoor transmitter to the Solar Clock (in open space). However, this

depends on the surrounding environment and interference levels. If no

reception is possible despite the observation of these factors, all system

units have to be reset (see “TO INSTALL / REPLACE BATTERY IN THE

SOLAR CLOCK” and “INITIAL SETUP”).

POSITIONING THE SOLAR CLOCK:

Before permanently mounting, ensure that the Solar Clock is able to

receive 915MHz signals from the desired location. In addition, the Solar

Clock should be placed in a bright environment for the rechargeable

batteries to be able to recharge.

There are two possible ways to mount the solar clock:

use of the foldable table stands, or

wall mounting

WALL MOUNTING

1. Install a mounting screw (not included) into a

wall—leaving approximately 3/16 of an inch

(5mm) extended from the wall.

2. Place the Solar Clock onto the screw, using the

hanging hole on the backside. Gently pull the

Solar Clock down to lock the screw into place.

Note: Always ensure that the Solar Clock locks onto

the screw before releasing.

POSITIONING THE SOLAR TRANSMITTER:

It is important to place the solar transmitter in a bright environment for the

rechargeable batteries to be able to recharge.

The solar transmitter can be placed onto any flat surface or wall mounted

using the bracket which doubles as a stand or wall mount base.

To wall mount: Secure the bracket onto a desired wall using the screws

and plastic anchors.

Clip the solar transmitter onto the bracket.

Note: The mounting surface can affect the transmission range.

If, for instance, the unit is attached to a piece of metal, it may

then either reduce or increase the transmitting range. For this

reason, we recommend not to place the unit on any metal

surfaces or in any position where a large metal or highly

polished surface is in the immediate vicinity (garage doors,

double glazing, etc.). Before securing in place, please ensure

that the Solar Clock can receive the 915MHz signal from the

solar transmitter at the positions that you wish to place them.
