                  Proper Use of The N.M.T. Trick Clip        
        
        
        
        After phone disassembly locate 27c512 EPROM on phone board.
This is on the upper right side of the display next to the ROAM indicator.
this is a 32 pin square device.  *NOTE: the dot and beveled edge for pin
orientation (the dot is pin 1) count to the left or counter clockwise 2
3 4 5 and so on.

        To the right, or clockwise of the dot is pin 32 Vcc.  This will
aid you in your count to find pin 25 wihch is the EPROM output enable.
this pin is at ground or V55-level.

*NOTE: Pin 25 on EPROM in phone must be lifted from the phone board ground or
V55 state, use an X-acto nife and or soldering Iron and tools to cut pin at
board level were pin norrows do not bend wide part of pin up on EPROM as this
could break of off EPROM.  Also wide part of pin will be used to make contact
the 'trick clip'.

*NOTE: Trick clip could be tuching norrow part of cutoff pin on the board thus
causing phone not to power up so remove or folddown as low as possible so trick
clip only tuches side of EPROM.  After programming is compleate you can put pin
25 back together if you feel like it for software below 9308, other software
will require you to put pin 25 back together or find a suitable ground or VSS
source.  To use the trick clip pull the locking wedge on the trick clip into the
upper possiton section of the trick clip adapter onto the EPROM of the phone.
Make sure to orient the dot and the edge with each other push locking wedge down
to lock the trick clip onto the EPROM on the phone.  Now proceed to re-program
your phone with the software and cables.  If everything is done correctly your
phone should power up and the green light should come on display.
