Introduction

This manual provides detailed instructions for the proper handling, storage, and charging of the Leonardo XR headset and its controllers. Carefully follow these guidelines to ensure maximum lifespan and reliability of the equipment.

1. HEADSET CHARGING STRATEGY

1.1. Battery Technical Specifications

• Battery capacity: 5500 mAh • Charging system: Quick Charge 3.0 (QC 3.0) • Charging port: USB Type-C • Operating temperature during charging: -10°C ~ +45°C • Full charging time: approximately 2-3 hours with a QC 3.0 charger

1.2. Correct Charging Procedure

1. Connect the QC 3.0 charger to an electrical outlet (100 – 240V, 50 – 60Hz). 

2. Insert the USB-C cable into the headset port (left side of the device).

 3. During charging, the status LED will display: 

• BLUE flashing LED: Charging in progress (battery 20% – 90%) 

• GREEN flashing LED: Charging nearly complete (battery > 90%) 

• RED flashing LED: Charging in progress (battery < 20%) 4. Once 100% is reached, the LED indicator will turn green and flash very slowly. 5. Disconnect the cable when charging is complete to preserve battery lifespan.

1.3. Strategy to Prevent Operational Interruptions

To ensure the headset is always ready for use and to prevent interruptions during work or training sessions, follow these recommendations: 

• SCHEDULED CHARGING: Establish a daily or weekly charging routine depending on usage.

• OVERNIGHT CHARGING: If the headset is used during the day, charge it overnight. Disconnect in the morning.
• BATTERY LEVEL MONITORING: Regularly check the battery level by briefly pressing the Power button.
• PREVENTIVE CHARGING: Charge the headset when the battery drops below 30%; do not wait until it is completely depleted.

1.4. Charging Schedule Example

Usage Frequency	Charging Strategy	Notes
Daily Use (3-4 hours/day)	Overnight charging every day	Disconnect in the morning
Intensive Use (6+ hours/day)	Charge twice a day	Consider using a backup headset
Occasional Use (2-3 times/week)	Charge after each use	Maintain at 50-70% when not in use
Sporadic Use (Once a week)	Charge before use	Check battery level weekly
Prolonged Storage (>2 weeks)	Charge to 50-70% before storage	Check and recharge every 2 months

2. CONTROLLER CHARGING STRATEGY

2.1. Controller Technical Specifications

• Power source: 1 AA battery per controller (2 batteries total required)
• Operating current: < 100mA
• Standby current: < 1mA
• Auto-shutoff: after 2 minutes of inactivity
• Battery life with rechargeable batteries (2800mAh): approx. 40 hours of use

2.2. Recommendation: Rechargeable Batteries

Any type of AA battery can be used; however, for professional operations and to minimize operational costs, we STRONGLY RECOMMEND the use of high-capacity 1.2V rechargeable AA batteries.
IMPORTANT
Do not wait for the batteries to be completely depleted before replacing them. Replace
the batteries when the displayed charge level drops below 20% to avoid interruptions
during use and to preserve battery health.
If 1.5V batteries are used, the headset will not display the correct charge level.

2.3. Optimal Battery Management System

To ensure the controllers are always ready for use, implement the following system:

2.3.1. RECOMMENDED KIT:

• 1 pack of rechargeable AA batteries (8 x 2800mAh cells)
• 1 fast charger compatible with 8 batteries
• 1 storage container for charged batteries (labeled “CHARGED”)
• 1 storage container for discharged batteries (labeled “TO CHARGE”)

2.3.2. BATTERY ROTATION PROCEDURE:

PHASE 1 – INITIAL SETUP (~4h):• Fully charge all 8 batteries.
• Insert 1 battery into each controller (total: 2 batteries in use).
• Keep 6 charged batteries in the “CHARGED” container as backup.
PHASE 2 – DURING USE:
• Monitor battery levels via the indicator inside the headset.

PHASE 3 – REPLACEMENT (~1 min):
• Remove depleted batteries from the controllers.
• Place depleted batteries in the “TO CHARGE” container.
• Take 2 charged batteries from the “CHARGED” container.
• Insert the charged batteries into the controllers.
• Continue use without interruption.
PHASE 4 – RECHARGING (~4h):
• At the end of the workday or when 4 batteries are depleted.
• Place all depleted batteries in the charger.
• Leave to charge for 4 hours (or follow the charger’s instructions).
• Once charged, move them to the “CHARGED” container.
• The system is ready for the next cycle.

2.4. Controller Recharging Schedule

Usage Scenario	Required Batteries	Strategy
Daily Use (3-4 hours)	8 batteries (2 in use + 6 in reserve)	Weekly charging
Intensive or Multi-user Use	8 batteries (2 in use + 6 in reserve)	Daily charging
Events or Intensive Training	8 batteries (2 in use + 6 in reserve)	Continuous overnight charging

2.5. Battery Insertion and Removal Instructions

2.5.1. How to Insert Batteries into the Controllers:

1. Slide down the battery compartment cover located on the back of the controller.
2. The cover will open, revealing the battery compartment.
3. Insert one AA battery, observing the polarity markings inside the compartment (+ and -).
4. IMPORTANT: The positive (+) terminal of the battery must face the top of the controller.
5. Slide the cover back up until you hear a clicking sound to secure it.
6. Turn on the controller by pressing and holding the Home button for 2 seconds.
7. Verify that the indicator LED lights up to confirm proper installation.

2.5.2. How to Remove Batteries from the Controllers:

1. Turn off the controller by pressing and holding the Home button for 6 seconds.
2. Slide down the battery compartment cover.
3. Gently remove the battery from the compartment.
4. If the battery is depleted, place it in the designated “TO BE CHARGED” container.
5. For long-term storage, keep the batteries separately in a cool, dry place.

3. DEVICE STORAGE

3.1. Storing the Leonardo XR Headset

When the headset is not in use, follow these procedures:
• Store the headset in a dry, clean place, away from heat sources, direct sunlight, and moisture.
• Recommended storage temperature: between -20°C and +60°C (ideal room temperature: 15–25°C).
• Store the headset in its original case or a protective container to prevent scratches and accidental damage.
• Ensure the lenses are NOT exposed to direct sunlight or intense light sources. Concentrated light can irreversibly damage the internal display.
• Place the headset with the lenses facing downward or toward a dark surface to protect the screen.
• Gently clean the lenses with a microfiber cloth before storing the device.
• Remove the detachable magnetic cushions and clean them separately if needed.
• If the device will not be used for more than 2 weeks, ensure the battery is charged to 50–70% before storage.

3.2. Storing the Controllers
To store the controllers under optimal conditions:

• Remove the AA batteries from the controllers if they will not be used for more than 1 week.
• Store the controllers in a dry place at room temperature (15–25°C).
• Avoid leaving the controllers in environments with temperatures above 35°C or below -10°C.
• Store the controllers in the case or a protected compartment to prevent impacts.
• Ensure the controllers are clean and dry before storage.
• Never leave drained or damaged batteries inside the controllers.
• Store the safety straps together with the controllers.
