- Ventilation Grilles: For proper airflow.
Setup
1. Powering the Unit
- Insert backup batteries (e.g., 2 x AAA, not supplied) into the battery compartment on the rear of the unit. This is for memory retention during power interruptions.
- Connect the provided mains power adapter to the "DC 5V" input port on the rear of the unit.
- Plug the mains power adapter into a suitable wall outlet. The display will illuminate.
2. Outdoor Sensor Setup
- Insert batteries (e.g., 2 x AA, not supplied) into the outdoor temperature sensor.
- Place the outdoor sensor in a sheltered location outside, away from direct sunlight and rain, to ensure accurate temperature readings. Ensure it is within range of the main unit.
- The main unit should automatically connect to the outdoor sensor. The outdoor temperature will appear on the display. If it does not connect, press and hold the "+" button on the main unit to initiate a manual search for the sensor.
3. Radio Controlled Time Synchronization
Upon initial power-up, the clock will automatically attempt to synchronize with the radio time signal (e.g., MSF signal in the UK). This process may take several minutes to an hour. Ensure the unit is placed in an area with good signal reception, away from electronic interference.
- A radio signal icon will flash on the display during synchronization.
- Once synchronized, the icon will become solid, indicating successful time reception.
- If synchronization fails, try repositioning the clock or manually initiate a search by pressing and holding the "+" button.
Operating Instructions
Setting Time and Date Manually (if radio control is unavailable)
- Press and hold the MODE button until the time display starts flashing.
- Use the + or - buttons to adjust the hour. Press MODE to confirm.
- Repeat for minutes, year, month, and day.
- Press MODE again to exit settings.
Setting Alarms
- Press the MODE button repeatedly until "AL1" or "AL2" appears on the display.
- Press and hold the MODE button until the alarm time flashes.
- Use the + or - buttons to set the desired alarm hour and then minutes.
- Press MODE to confirm.
- Slide the corresponding Alarm ON/OFF switch (on the right side) to the "ON" position to activate the alarm. An alarm icon will appear on the display.
- When the alarm sounds, press the SNOOZE area (top of the unit) to activate snooze. The alarm will sound again after approximately 5 minutes.
- To stop the alarm completely, slide the corresponding Alarm ON/OFF switch to "OFF".
Display Brightness and Colour
- The display features multiple colours and adjustable brightness. Refer to the specific buttons on the rear of the unit (if present, or front controls) for colour loop and brightness adjustment.
- Typically, a dedicated button or a combination of MODE and +/- buttons controls brightness levels.
Time and Temperature Projection
The unit can project the time and temperature onto a wall or ceiling.

This image illustrates the Acctim 71863 Sirius clock projecting the time and temperature (e.g., "12:58" and "18°") in red onto a surface above the unit.

This image shows the Acctim 71863 Sirius clock with its projection module extended, clearly displaying the projection lens and the projected time and temperature in red.
- Locate the projector lens on the side of the unit.
- Adjust the angle of the projector to direct the image onto your desired surface.
- Use the focus wheel (if present, usually near the lens) to sharpen the projected image.
- The projection feature can typically be turned ON/OFF via a dedicated button or by pressing a specific combination of main unit buttons.
Using the USB Charge Port
The USB charge port (5V === 1A) on the side of the unit allows you to charge compatible electronic devices, such as smartphones or tablets. Simply connect your device's USB charging cable to this port.
Maintenance
- Clean the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ensure the ventilation grilles on the rear are not obstructed.
- Replace backup batteries annually or when the display shows a low battery indicator (if applicable).
- For the outdoor sensor, check and replace batteries as needed, especially before winter months.
