INSTRUCTIONS FOR INSTALLING CHIPS IN THE INN-FORM/XL

#1   Go into management access and run PROGRAM #10, PROGRAM #20 and    
     PROGRAM #32.  If you have programmed Automatic Multi Reports, you    
     will also need to print out a Multi Report #7 for a copy of how        
     the reports are set up.  These printouts clearly show any on site      
     programming that was done and can be referenced when re-
     programming the system.

#2   For the INN-FORM/XL you can do a program #153 which is a mass         
     check out (this is not necessary in the TEL-SENSE).  The program       
     #153 will flag all calls to appear on the extension audit.  Run        
     any reports that you need on the call records stored in the         
     memory of the system. *** THIS IS VERY IMPORTANT *** because all       
     the call records will be erased after the installation of the new      
     chip(s).

#3   UNPLUG the call accounting system from the printer, the telephone 
     system and the power supply.  Make sure you are grounded.  Turn the
     call accounting system over and remove the screws.  Carefully take the
     back off.

#4   THE DATA CHIP - The large chip on a black plastic carrier, in the
     socket located in the corner of the circuit board is the data (or
     property) chip.  Remove the old data chip with it's carrier from the
     socket carefully and place the new data chip in the socket (this chip
     always comes on it's own black plastic carrier).  Make sure that there
     is a black jumper on pins two and three of the five pin connector
     beside the data chip socket.

#5   THE FIRMWARE CHIP U10 - Remove the screws that secure the circuit
     board to the case and  gently fold the circuit board over so the other
     side of the board is visible.  The existing firmware chip will be
     clearly marked U10.  Locate the notch on the existing firmware chip. 
     When installing the new firmware chip (also marked U10) make sure the
     notch is facing in that same direction.  INSTALL the new firmware
     chip.  Make sure no pins are bent and all pins mate to the socket.

#6   Carefully put the system back together.

#7   Plug the call accounting system back into the power.  If the chip(s)
     have been installed correctly the call accounting system will show
     time and date in the display.

#8   Go into management access, run PROGRAM #248.  You must press the "$"
     (found in the upper right hand corner of the system) to reset the
     XL/TS systems.  Program #248 tells the system to initialize and read
     the information from the new data chip.  The system will print out a
     program #10 and a re-initialization message.

#9   System defaults to a MODE #0.  If previously in MODE #7 (mode 7
     prints wake-up calls) then place back into by the following 
     keystrokes.  Mngt access - access code - enter - mode set - 7 -
     enter.

#10  Re-program any on-site parameters (ie grace periods, surcharges,
     mark-ups, etc.).  The system is now ready to process call record
     information.
