3.3 Handset Registration
Your handsets are pre-registered to the base unit. If a handset displays 'To register HS' or 'Place HS on base', you may need to manually register it. Place the handset on the base unit. The handset should automatically begin the registration process. If not, refer to the Quick Start Guide for specific manual registration steps.

5. Maintenance
5.1 Cleaning the Phone
Wipe the phone and base unit with a soft, slightly damp cloth. Do not use cleaning sprays or harsh chemicals, as they may damage the finish or electrical components.
5.2 Battery Care
To ensure optimal battery life, always return the handset to the charging cradle when not in use. If the phone will not be used for an extended period, remove the battery from the handset.
6. Troubleshooting
If you experience issues with your VTech VG131-21, try the following solutions:
- No dial tone: Ensure the telephone line cord is securely connected to both the base unit and the wall jack. Check that the AC adapter is plugged in and the base unit has power.
- Poor sound quality/static: Move the handset closer to the base unit. Ensure no other electronic devices are interfering with the signal. DECT 6.0 technology minimizes interference, but extreme distances or strong interference sources can affect quality.
- Handset not charging: Ensure the handset is properly seated in the charging cradle. Check that the charging contacts on both the handset and cradle are clean. Verify the AC adapter for the base unit is connected.
- Handset out of range: If the handset displays 'Out of range' or similar, move closer to the base unit. The optimal range is up to 1000ft outdoors, but indoor range can vary due to obstacles.
- Display difficult to read: The display has a blue-white backlight. Ensure you are viewing it at an appropriate angle.
