GETTING STARTED
BATTERIES
Insert batteries before first use, matching the polarity (+ and -). Press RESET after each battery change.

indicates main unit batteries are low.
NOTE
Do not use rechargeable batteries. We recommend that you use alkaline batteries with this product for longer usage and lithium batteries in temperatures below freezing.
REMOTE SENSOR
The sensor collects temperature readings approx. every 40 seconds and sends them to the main unit. The main unit can collect data from up to 3 sensors.
To set up the sensor:
- Remove the screws from the battery door.
- Insert the batteries, matching the polarity (+ / -).
![Oregon Scientific - BAR688HG - Setting up the sensor - Step 1 Setting up the sensor - Step 1]()
- Select a channel. Make sure you use a different channel for each sensor.
- Place the sensor near the main unit. Press RESET on the sensor.
- Simultaneously press CHANNEL and MEM on the main unit to initiate signal sending between the sensor and main unit.
- Close the battery door and secure the screws.
- Place the sensor in the desired location using the table stand or wall mount.
![Oregon Scientific - BAR688HG - Setting up the sensor - Step 2 Setting up the sensor - Step 2]()
For best results:
- Place the sensor out of direct sunlight and moisture.
- Do not place the sensor more than 30 m (100 ft) from the main (indoor) unit.
- Position the sensor so that it faces the main (indoor) unit, minimising obstructions such as doors, walls, and furniture.
- Place the sensor in a location with a clear view to the sky, away from metallic or electronic objects.
- Position the sensor close to the main unit during cold winter months as below-freezing temperatures may affect battery performance and signal transmission.
The transmission range may vary depending on many factors. You may need to experiment with various locations to get the best results.
Standard Alkaline batteries contain significant amounts of water. Because of this they will freeze in low temperatures of approximately -12°C (10°F). Disposable Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -30°C (-22°F).
Wireless ranges can be impacted by a variety of factors such as extremely cold temperatures. Extreme cold may temporarily reduce the effective range between the sensor and the base station. If the unit's performance fails due to low temperature, the unit will resume proper functioning as the temperature rises to within the normal temperature range (i.e. no permanent damage will occur to the unit due to low temperatures).
SENSOR DATA TRANSMISSION
The sensor reception icon in the remote sensor area shows the status.
| ICON | DESCRIPTION |
![]() | Main unit is searching for the sensor(s) |
![]() | A channel has been found and sensor signal is being received |
and "- -. -"(Outdoor temperature Area) | The sensor cannot be found. Search for the sensor or check batteries |
To search for a sensor:
Simultaneously, press and hold MEM and CHANNEL for 2 seconds.
NOTE
If the sensor is still not found, check the batteries, obstructions, and remote unit location.
CLOCK
CLOCK RECEPTION
This product is designed to synchronise its date and time automatically once it is within range of:
- DCF-77 generated from Frankfurt, Germany for Central Europe.
MSF-60 generated from Anthorn, England.
The clock collects the radio signals whenever it is within 1500 km (932 miles) of a signal.
NOTE:
Slide the EU / UK switch to appropriate position for your location. Repeat each time you reset the unit.
NOTE:
Initial reception takes 2-10 minutes for first set up or when RESET is pressed. Once complete, the reception icon will stop blinking. If the signal is weak, it can take up to 24 hours to get a valid signal.
RECEPTION SIGNAL
Clock signal reception indicator:
| STRONG SIGNAL | WEAK SIGNAL | NO SIGNAL |
| | |
To enable and force a signal search:
Press and hold
for 2 seconds.
To disable the signal reception:
Press and hold
for 2 seconds.
SET CLOCK
If the clock signal reception is enabled and a signal is being received the clock does not need to be manually set.
- Press and hold MODE for 2 seconds.
- Press
or
to change the settings. - Press MODE to confirm.
- The settings order is: time zone offset, hour, minute, year, month, day and language.
NOTE:
The time zone offset can be used to set the clock up to + / - 9 hours from the received clock signal time. If you have disabled the clock signal reception (i.e. manually setting the clock), do not set a value for time zone offset.
NOTE:
The language options are English (E), German (D), French (F), Italian (I), and Spanish (S).
Press MODE to choose between the clock with seconds and clock with weekday display modes.
ALARM
