If “No link to base. Move closer to base, try again.” is displayed
even when using the handset near the base unit, the handset may have lost communication with the base unit. You need to re-register the handset to the base unit.
• Make sure the base unit is not being used.
• Have both handsets and base unit nearby during registration.
• Follow steps 1–3 listed below. You have about 1 minute to complete them.
• Confirm the extension number of the handset which has lost the communication by placing the handset on the base unit or charger.
If you re-register the handset using the other handset’s extension number, the other handset will not function.
• If the handset beeps 3 times and “Error!!” is displayed, an error occurred. Try again from step 1.
• You can stop registration by pressing [OFF] on the handset, and pressing [LOCATOR/INTERCOM] on the base unit.
1 Base unit: Press and hold [LOCATOR/INTERCOM] until a beep sounds.
• The CHARGE indicator flashes.
2 Base unit: Press the extension number  (handset symbol 1 ) or  (handset symbol 2) of the
handset which has lost the communication.
3 Handset: Press and hold [FLASH/CALL WAIT] until “Handset Registering” is displayed.
• When registration is complete, a beep sounds from the handset and the display shows the number. • Wait for 20 seconds after registration is complete while the handset establishes communication with the base unit.
• If the handset beeps 3 times and “Error!!” is displayed, an error occurred. Try again from step 1. • You can stop registration by pressing [OFF] on the handset, and pressing [LOCATOR/INTERCOM] on the base unit.

Panasonic KX-TG1050N Cordless Phone. Base handset (No. 1, KX-TGA100N) does not work, no keypad response or dial tone. Green indicator message light ON (should only work with the TG1000N base unit) all the time till battery runs down. Display shows message ?C533?. Can still send and receive calls on extension phones 2 and 3.
Put extension phone on base unit; press menu; press 0 0; press and hold intercom until charging light starts flashing. the display should show OK on the display screen of the extension phone; press OK. If you have more than one extension to add:
after you press 00; the symbol for # # # will come up. Enter a number for that extension i.e. 2; 3; or your choice.OK will come up on display at bottom right of display; press ok. hope this helps. This info should come on the extension phone and "menu" is on ext. unit. So turn the display up so you can see it while it is on base unit.
