In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

SKY SCAN ATOMIC CLOCK 87310 SETTINGS AND TROUBLE SHOOTING


SKY SCAN 87310 

ATOMIC CLOCK 

SETTINGS AND TROUBLE SHOOTING 

MANUAL SETTINGS
Note: If the Atomic Clock has already successfully received the WWVB time signal and displays the correct time and date, then the Manual settings can be omitted.
After completion of the above described procedures in “Setting up” the manual setting modes can be entered by pressing the SET key. The following settings can now be programmed:
# Time zone setting
# DST ON/OFF
# Language display setting
# Manual time setting
# Year setting
# Month setting
# Date setting
# Weekday setting
# 12/24 hour time display setting
# ºC or ºF setting
TIME ZONE SETTING
After entering the manual setting mode as described above, the time zone can be set between the –1 to –12 hour or Greenwich Mean Time (GMT) range in LCD2. To do this:

1. The time zone (LCD2) will start flashing (Default setting "-5h“). Select the desired time zone by use of the + key.
Note: The time zones from –4 to –10 hours will be displayed with 3 characters abbreviations:
-4 ATL (Atlantic time),
-5 EST (Eastern time; default time zone),
-6 CST (Central time),
-7 MST (Mountain time),
-8 PST (Pacific time),
-9 ALA (Alaska time),
-10 HAW (Hawaii time).
"GMT” will be displayed if set to GMT (0).
2. Press the SET key to enter the “DST Setting“
DST SETTING (daylight saving time)
1. The ON digit will start flashing on LCD1. Set the DST ON or OFF by pressing the + key.
2. Press the SET key to enter the “Language Setting“.
Note: The DST default is “ON”, meaning that the WWVB will automatically change the time according to Daylight Saving Time in the spring and fall. For areas that do not recognize DST changes (Arizona and parts of Indiana)turn the DST “OFF”.
LANGUAGE SETTING
The weekdays can be displayed in LCD1 with the preset languages: US English, French and Spanish.
1. Set the desired language for the weekday display in LCD 2 by use of the + key.
2. Press the SET key to enter the mode “Manual Time Setting”.
MANUAL TIME SETTING
In case the Skyscan Atomic Clock is not able to detect the WWVB-signal (disturbances, transmitting distance,
etc.), the time can be manually set. The clock will then work as a normal Quartz clock.
Note: In 12 hours mode the time will be displayed with an additional PMfor the time from 12:00 noon until 11:59.
1. The hour digits will start flashing on LCD1. Set the desired hours by pressing the + key followed by pressing the SET key.
2. Now the minute digits will start flashing. Set the desired minutes by pressing the + key . If the + key is held, the units will increase by 5.
3. Press the SET key to move to the “Year Setting”.
Note:
The unit will still try and receive the signal every day despite it being manually set. When it does receive the signal, it will change the manually set time into the received time. During reception attempts the WWVB tower icon will flash. If reception has been unsuccessful, then the WWVB tower icon will not appear but reception will still be attempted the following hour. WWVB time reception takes place from 12:00 am through 6:00 am each day (attempts WWVB reception every full hour within this time frame). When the time signal is received for example at 1:00 am, the Skyscan Atomic Clock will not attempt to receive the WWVB signal for the remaining hours until 6:00 am. Therefore, the next signal attempt will take place between 12:00 am and 6:00 am the next day. The other times WWVB reception takes place, are upon setup and after manual time set exiting mode. Reception is generally not possible during daylight hours due to the interference of the sun.
YEAR SETTING
The year can be selected sequentially from 2000 to 2049 and will then start over again (default setting 2000). Only the last 2 digits of the year will be visible on LCD2 .
1. The year digits will start flashing on LCD1. Select the desired year by use of the + key.
2. Press the SET key to switch to the “Month Setting”. MONTH SETTING
1. The month digits on LCD2 will start flashing. Set the desired month by use of the + key.
2. Press the SET key to move to the mode “Date Setting”. DATE SETTING
1. The digits for the date will start flashing on LCD2
(Default setting 1). Set the desired date by use of the + key.
Note:
The date can only be set in conjunction with the selected month. For example, it is not possible to set the date 30 if the month of February is selected.
2. Press the SET key to enter the “Weekday Setting”.
WEEKDAY SETTING
1. The weekday symbols will be displayed on LCD2 in the pre-set language and flashing. Set the desired weekday by use of the + key.
2. Press the SET key to enter the mode “12/24 Hours Time Display Setting”.
12/24 HOURS TIME DISPLAY SETTING

2. Press the SET key to enter the
“ºC/ºF Temperature Setting“. °C OR °F TEMPERATURE SETTING
1. The characters “°C” or “°F” will start flashing on LCD1 (Default setting °F). By use of the + key select “°C” for temperature display in degrees Celsius or “°F” for degrees Fahrenheit.
2. Press the SET key to exit the setting mode and switch back to the normal display mode .
EXIT THE MANUAL SETTING MODES
• To return to the normal display mode from anywhere in manual setting mode simply press the SNZ key anytime.
• If no keys are pressed for at least 15 seconds in setting mode, the Atomic Clock will automatically switch back to normal display mode.
ALARM SETTING
To enter into the alarm setting mode:
1. Hold the ALM key for 2 seconds. The hour digits start flashing.
2. Press the + key to set the hour.
3. Press the ALM key to set the minutes. The minute digits start flashing.
4. Press the + key to set the minutes.
5. Press again the ALM key to exit the Alarm setting mode or wait for 15 seconds automatic timeout.
TO DEACTIVATE THE ALARM:
The alarm will be automatically ON. To deactivate the alarm (OFF), press once the ALM key in normal mode display.
SNOOZE SETTING
The snooze can only be activated during alarm time for a snooze duration of 10 minutes.
OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the Skyscan Atomic Clock every 1 minute. The Atomic Clock will update the temperature display every 5 minutes. The range of the Outdoor Temperature Transmitter may be affected by the temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when positioning the transmitter. Also the batteries may be reduced in power.
433MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The Atomic Clock will receive the temperature data within 4 minutes. If the temperature data is not being received 4 minutes after setting up (the display shows “- - -”), then please check the following points:
1. The distance of the Atomic Clock or Outdoor Temperature 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 (433MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 433MHz signal frequency can also cause interference.
Note: When the 433 MHz signal is received correctly, do not re-open the battery cover of either the Outdoor Temperature Transmitter or Atomic Clock, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission
problems may occur.
The maximum transmission range is 82 feet (25 meters) from the Outdoor Temperature Transmitter to the Skyscan Atomic 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 Setting up)
CARE AND MAINTENANCE:
• Avoid placing the units in areas prone to vibration and shock as these may cause damage.
• Avoid areas where the units can be exposed to sudden changes in temperature, i.e. direct sunlight, extreme cold and wet/moist conditions as these will lead to rapid changes which reduces the accuracy of readings.
# When cleaning the LCD and casing, use a soft damp cloth only. Do not use solvents or scouring agents.
# Do not submerge the units into water.
# Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended size.
# Do not make any repairs to the units. Please return it to the original point of purchase. Opening and tampering with the units may invalidate the warranty
TROUBLESHOOTING
No reception of WWVB signal
1) It may help reception to face the front of the Atomic Clock in the general direction of Ft. Collins, Colorado.
2) Wait overnight for signal.
3) Be sure the Skyscan Atomic Clock is at least 6 feet (2 meters) from any electrical devices, i.e. TV sets, computers, or other radio controlled clocks.
4) Remove batteries for five minutes, reinsert and leave the unit alone overnight without pressing any keys.
Hour is incorrect (minute and date are correct).
1) Be sure the correct time zone and daylight saving time are selected.
"OFL“ appears in the indoor temperature section of the LCD
1) Move the Skyscan Atomic Clock to an area with warmer or cooler
surrounding temperature. Current surrounding temperatures are outside measuring range.
"--.-" appears in the outdoor temperature section of the LCD.
1) Remove the batteries of both units for one minute, then reinsert them again. Make sure the batteries are new and fresh.
2) Move the Atomic Clock closer to the transmitter or place the transmitter closer to the Skyscan Atomic Clock. Make sure the clock is at a receivable range from the transmitter.
3) Move the units to another location. Interferences from other electrical devices operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception.
"OFL“ appears in the outdoor temperature section of the LCD.
1) Wait until the current surrounding temperature cools down or increases. Current temperature is outside of the measuring range of the transmitter. The outdoor temperature will be displayed again once the current surrounding temperature is within the range of the transmitter.
