• Keep all contact surfaces clean of dirt and hand-grease
• Removing Front Cover and Antenna Cover is very hard, due to that you do not know how
much force that is needed unsnapping these parts. It also requires much technique
removing these two parts. Training is very important, both by performing training in
Learning Community and by hands on practice.

4 Separating front from frame:
1A-1B hooks:
Put the phone on a flat, clean surface. First
release hooks 1A and 1B close to the system
connector. Use a screwdriver, width 3 mm.
NOTE!
ESD gloves must not be used when separating
snap fit hooks.
Be careful when using the screwdriver, hooks
are tight fitted and you may easily slip and injure
your fingers. Also be careful not to scratch the
frame and damage front hooks with the
screwdriver.
Put Place the screwdriver in the slot (1B). Press
directly down hard to release the snap fit hook.
Do the same on the opposite side. The phone
should be placed on a flat, clean surface during
the releasing of 1A -1B hooks.
NOTE!
Do not use any tool or your nail to separate front
from frame, front will easily get scratched. The
only way to separate front from frame is to
release hooks according to the instruction.
The screwdriver should be in 90 degrees angle
when releasing the bottom front snap fit hooks.
NOTE!
When removing the front cover the first time, it
is hard to predict the amount of force needed.
Usually it requires more force then you think.
Pushing of 1A & 1B is the hardest part!
When the two bottom hooks are released a small
gap is seen between front and frame.

1C-1H hooks:
NOTE! Now use the K700 Front opening tool
and NOT the screwdriver for snaphooks 1C-1H.
Angle the new K700i/Front opening tool, as the
picture shows, when releasing the hooks.
Place the K700i/Front opening tool (in correct
angle), close to the frame and press down to
release the snap fit hooks. Begin with snap
hooks marked (3). No hard force is needed.
Whereupon hooks are released the gap between
front and frame increases.
Continue to release hooks (1E/F resp 1G/H).
NOTE! You might need to repeat releasing the
hooks a few times as they easily get back to
original location.
The frame is firmly clamped on to the top of the
phone and cannot be dislodged easily.
Gently lift the front cover upwards to separate
front and frame. The two top hooks will be
released with a “break” sound, this sound is
normal. As long as you remove the front gently
there will be no damage on the front or its snap
hooks.
The keypad might fall out. If not remove it with
your fingers.
5 NOTE! Be careful and don´t touch the display.
Remove the 4 screws.
NOTE!
Removed screws cannot be reused and must be
scrapped.

6 Remove the joystick button with your fingers.
NOTE!
The joystick may be tight fitted to the switch.
7 Use front opening tool to separate the metal
carrier from the frame. Two frame snap fit
hooks, located in the middle section, shall be
released.
Place the opening tool close to the metal carrier
and press down until the hook moves to the
frame wall (1).
Angle the opening tool, as the picture shows (2),
until the metal carrier is released. Do the same
on the opposite side of the metal carrier.
Remove the metal carrier.
The system connector plug will most likely fall
out when releasing the metal carrier (3). If not
remove the plug.

12 Antenna Cover removal:
NOTE!
The antenna cover should only be removed if
there is a need of replacing the antenna cover
itself, the frame or any of the following
components located underneath the antenna
cover:
Volume and camera keys
Internet access key
Antenna flex
Flexfilm volume and camera key
Flexfilm camera light assembly
Camera (for verifying that the camera is fitted
properly)
There is no need to remove the external antenna
connector plug.
Use a dentist hook or a flat screwdriver to
remove the antenna cover. As long as you do not
scratch the antenna cover or frame, you can use
the tool that you feel most comfortable with. If
you use a sharp tool be careful not to damage the
snap hook.
When removing the antenna cover the first time
it is hard to predict the amount of force needed.
Usually, as when removing the front cover, it
requires more force then you think.
If the phone is already disassembled, and
there is a need for removing the antenna
cover, it is OK to unsnap the antenna cover
snap hooks from the inside.

Put your thumb under the edge of the camera
ring. When pressing on the snap hooks use your
thumb to pull off the antenna cover. It is very
tight fitted and requires some force to pull up.
Take the tool you have chosen (flat screwdriver
or dentist hook) and press hard on the snap
hook as the green arrow shows.
NOTE!
Do not press between the frame and snap hook.
As the red arrow shows. You will only damage
the phone, not release the snap hook.
Be careful not to scratch frame or antenna cover.
At the same time pull with your thumb under the
antenna ring. Press with the tool and pull with
your thumb until you feel that the snap hook get
released with a click sound.
Green marking shows area where to press.
Be prepared for a sudden release of the Antenna
Cover. Most force is required pulling up the
cover with your thumb.
Unlocked snap hook. Do the same on the
opposite side of the antenna cover. Lift the cover
up to remove the antenna cover.
NOTE!
The volume/camera key and internet access key
will most likely fall out when the antenna cover
is removed.
