Setup
1. Battery Installation
- Locate the battery compartment cover on the back of the remote control.
- Slide the cover downwards or press the latch to open it.
- Insert two (2) AA batteries, ensuring the positive (+) and negative (-) terminals align correctly with the markings inside the compartment.
- Replace the battery compartment cover, sliding it back into place until it clicks securely.
2. Initial Pairing for Voice Function
For the voice control feature to function, the remote must be paired with your Sony television. If you are replacing an existing remote, it may be necessary to unpair the old remote first.
- Ensure your television is powered on.
- On your television, navigate to the Settings menu. This is typically accessed via the HOME button on the remote (if it's already partially functional) or through your TV's physical controls.
- Within Settings, locate Device Preferences or Remotes & Accessories.
- Select Remote control or Add accessory.
- Follow the on-screen prompts to initiate the pairing process. The TV will typically instruct you to hold down specific buttons on the remote. For this model, it often involves holding the Volume Down button and the Google Assistant/Microphone button simultaneously for approximately 3 seconds until an orange light blinks on the remote.
- Once paired, a confirmation message will appear on your TV screen.
If you experience issues, refer to the Troubleshooting section or your television's specific user manual for detailed pairing instructions.

Maintenance
Battery Replacement
Replace batteries when the remote's response becomes sluggish or it stops functioning. Always replace both batteries simultaneously with new AA batteries. Do not mix old and new batteries, or different types of batteries.
Cleaning
To clean the remote control, wipe it with a soft, dry cloth. Do not use liquid cleaners, sprays, or abrasive materials, as these can damage the remote's surface or internal components.
Troubleshooting
- Remote not responding:
- Check if the batteries are correctly inserted and have sufficient charge. Replace if necessary.
- Ensure there are no obstructions between the remote and the television's IR receiver.
- If the remote uses Bluetooth (for voice function), ensure it is properly paired.
- Voice function not working:
- Confirm the remote is paired with the television for voice control (refer to "Initial Pairing for Voice Function" section).
- Ensure the television's internet connection is active, as voice commands often require online processing.

- This can indicate low battery power. Replace the batteries.
- Ensure the remote is pointed directly at the TV's sensor if it relies on infrared signals for basic functions.
- Remote not pairing with TV:
