15 Measurements and Adjustments

15.1. Cordless Base Section (Digital Board) Adjustment

When you have replaced EEPROM or BBIC or X'tal, adjustment is necessary.
This supplement will explain further details for adjustment.
15.1.1. Equipment Required
1. Frequency Counter
It's to adjust frequncy(10.368000MHz) of BBIC.
It requires an accuracy that can measure 1Hz.
(precise; ±1ppm)
2. Digital multimeter
It's to adjust voltage (1.8V) of BBIC.
15.1.2. How to Adjust
It adjusts it from the operation panel by the command input.
1. Setting to the cordless test mode in the service mode.
2. The corresponding command is input from the following
list.
Command
IDR
IDW
EPD
VER
VDD
SFR
15.1.2.1. In Case of EEPROM Replacement
When you replace EEPROM, you need to adjust Frequency and Voltage.
ID number has been already written to the EEPROM that you take from service center.
1. Initialize please input initializing command "EPD" and "F".
2. The command "MIP 0***" is input.
3. Adjust Frequency and Voltage.
--> Refer to "Frequency and Voltage Adjustment"
4. Confirm ID of Base unit.
Please check ID number with "IDR" command.
If ID is 00 00 00 00 00, please replace again.
5. Re-register CDL Handsets <-- Don't forget please.
Caution:
When the following command is input after the command is input, it is necessary to return it with the stop key.
15.1.2.2. In Case of BBIC Replacement
When you replace BBIC, you need to adjust Frequency and Voltage. -->Refer to Frequency and Voltage Adjustment (P.272).
15.1.2.3. In Case of X'tal (X900) Replacement
When you replace X'tal, you need to adjust Frequency. -->Refer to Frequency Adjustment (P.272).
Read ID number of Base unit.
Write ID number of Base unit.
**: ID number, example if ID number is 007B700000, input 00 7B 70 00 00
Initialize EEPROM: default vales are written to EEPROM.
" "
F is put after the command input. (EPD F)
Get Version of BBIC software: you can check Version.
