2. Installation Procedures
The Voltino Grand Digi Plus stabilizer is designed for wall mounting. Follow these steps for proper installation:
- Locate a suitable place: Choose a wall location near the equipment to be connected, ensuring adequate ventilation.
- Mark Drilling Holes: Use the provided wall mount sheet or measure 140 mm apart to mark the positions for drilling.
- Drill Holes: Drill holes with a diameter less than 7 mm at the marked positions.
- Insert Plastic Plugs: Gently insert the plastic plugs into the drilled holes.
- Mount Stabilizer: Insert the steel screws into the plastic plugs and securely mount the Voltino Stabilizer.

Connecting Devices:
The stabilizer features two 3-pin outlets. Connect your devices as follows:
- One outlet is for Smart/LED/LCD/OLED/3D TV (up to 80 inches).
- The second outlet is for HD/SD Set Top Box, Home Theatre System, or Gaming Console.
The stabilizer comes with a 6A 3-pin plug for connecting to the main power supply. Use a multipin adapter if connecting additional low-power loads, ensuring total load does not exceed the stabilizer's capacity.

3. Operating Instructions
Once installed and connected, the Voltino Grand Digi Plus operates automatically to protect your devices.
Power On/Off:
- Connect the stabilizer's power cord to a wall socket.
- The stabilizer will initiate its Initial Time Delay System (typically 4-6 seconds) before supplying power to connected devices. This delay protects devices from immediate power surges upon startup.
- To turn off, disconnect the stabilizer from the main power supply.
Digital Display:
The dual seven-segment digital display provides real-time information:
- The display alternates between showing the Output Voltage and the Input Voltage.
- A touch-sensing switch allows adjustment of the display brightness.

Voltage Regulation:
The stabilizer operates within a wide input voltage range of 90V to 290V. It automatically adjusts the output voltage to a safe level (around 220V-240V) for your devices.
- If the input voltage is within the normal operating range (e.g., 190V-250V), the output voltage may appear similar to the input, as no significant correction is needed.
- If the input voltage drops below the normal range (e.g., below 190V), the stabilizer will boost the output voltage (up to 40V boost).
- If the input voltage rises above the normal range (e.g., above 250V), the stabilizer will buck (reduce) the output voltage (up to 48V buck).

4. Maintenance
The V-Guard Voltino Grand Digi Plus TV Stabilizer requires minimal maintenance to ensure optimal performance and longevity.
- Cleaning: Periodically wipe the exterior of the stabilizer with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Ventilation: Ensure that the stabilizer's ventilation openings are not obstructed. Maintain adequate space around the unit for proper airflow.
- Connections: Regularly check all power connections to ensure they are secure and free from damage.
- Avoid Overloading: Do not connect devices that exceed the stabilizer's 4A capacity. Refer to the specifications section for details.
For any internal issues or repairs, contact authorized V-Guard service personnel only.
5. Troubleshooting
If you encounter issues with your V-Guard Voltino Grand Digi Plus TV Stabilizer, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Stabilizer not turning on / No display | No power supply to the stabilizer. |
|
| Connected devices not receiving power |
|
|
| Input and Output voltage display are similar | Input voltage is within the safe operating range. | This is normal operation. The stabilizer only corrects voltage when it falls outside the safe range (90-290V). If your input voltage is already stable, the output will match. |
| Stabilizer feels hot |
|
|
If the problem persists after following these steps, please contact V-Guard Customer Care.
