Safety Advisories/Warnings

Liability Disclaimer

VTech is not liable for any damage or defect caused by an attempted repair by an unauthorized provider, a self-repair or a non-professional repair.

Likewise, VTech is not liable for any resulting damage, injury or other safety problems caused by the device caused by an attempted repair that does not comply with these repair instructions.

Damage to the device or defects caused by an attempt to repair the device by a person other than a VTech-certified partner are not covered by the warranty.

Critical Safety Requirements

Original Parts Only: Always use original VTech spare parts. Third-party replacement parts may not work correctly and may result in property damage and/or personal injury.
Water/Dust Protection: The presence of water or dust tightness of the device cannot be guaranteed if it has been repaired by a user or other unqualified person.
Power Safety: Switch off the device before starting the repair and, if possible, remove all existing batteries and rechargeable batteries.
ESD Protection: Many components in electronic devices are particularly sensitive to static discharge and can therefore be easily damaged. Therefore, make sure that the static charge in the working environment is dissipated before you open packages with ESD protection or you start disassembling the device.
Assembly Check: Make sure that there are no loose parts, screws or foreign objects in the device when assembling the device.

Disassembly/Assembly

Dismantling the Handset

Handset Disassemble
Remove the battery cover from the device and remove the two batteries.
Insert the opening tool on the lower right side between the two housing shells and lever the tool in the indicated direction to release the first latch. A small gap is created.
Repeat the process following the indicated sequence around the device perimeter to release all latches systematically.
Lift the back shell slightly to remove the two battery springs and thus the back shell.
The PCB can now be easily removed from the housing.

Dismantling the Phone Base

Base Disassemble
Flip the base unit over and disconnect any power adapter or source.
Using a screwdriver, remove all visible screws from the underside of the base to release the rear housing.
Insert a opening tool into the gap between the upper and lower housings. Carefully work around the perimeter to release all internal latches. Gently lift and separate the upper and lower shells. Detach any internal wiring as needed.
Unscrew the Main PCB from its mount and lift it from the housing. Disconnect any daughter boards or socketed components.
Detach other components, like Keyboard PCB, Antenna Locker, and Charger Contact Assembly.

Dismantling the Charger

Charger Disassemble
Flip the base unit over and disconnect any power adapter or source.
Using a screwdriver, remove all visible screws from the underside of the base to release the rear housing.
Insert a opening tool into the gap between the upper and lower housings. Carefully work around the perimeter to release all internal latches. Gently lift and separate the upper and lower shells.
Take out the Main PCB from its mount and lift it from the housing.
Detach other components, like Charger Contact Assembly.

Mounting the Handset / Telephone Base / Charger

Assembly Guidelines

Use the exploded view to see the locations of each component for assembly. When mounting, make sure that the front and back are properly locked in place again.

Speaker Replacement

To replace the speaker, the housing must be opened following the disassembly procedure.
With the help of the opening tool, you can pry the speaker out of the housing.
When installing the speaker, make sure that the coding nose of the speaker is correctly seated in the cabinet shell.

Keyboard & Function Key Replacement

To replace the keyboard, the case must be opened and the PCB removed.
Remove the old keyboard and insert the new one into the lower shell of the case.
Now reassemble the complete device following the assembly procedure.

Display Replacement

Critical Temperature Setting

Equip your soldering iron with a shovel tip and set the temperature to 220°C

To replace the display, the case must be opened and the PCB removed.
To remove the display module, push the two locking lugs on the module away from the side.
Clean the adhesive surfaces completely. The residues of the old module should be completely removed from the contact surfaces.
Take the new display and fix it to the assembly with approximately 3cm long strip of Kapton tape. Make sure that the contact surfaces are correctly positioned.
Place the assembly on a flat surface so that the components on the back cannot be damaged and bending of the assembly is impossible.
To protect the film, use the included silicone tape. Glue the foil to the assembly with the soldering iron at 220°C.
Slowly pass the shovel tip over the foil from top to bottom with pressure. This process should take about 8-10 seconds to ensure complete gluing.
Repeat the process on the entire width of the screen protector to completely glue all areas.
Mount the display back on the assembly.

Display Recovery Procedure

If the display is faulty when you first turn it on after repairing:

  • Insert batteries
  • Turn off the device
  • Press and hold buttons 1, 4, 9 while turning on the device
  • The display should now work correctly again

Microphones, Charging Contacts & Headset Connector

To replace the microphone, the housing must be opened and the circuit board removed following the complete disassembly procedure.
Carefully remove the old component and install the replacement part.
Reassemble the device ensuring all connections are secure.
