Ð 3 Ð SECTION 1 SERVICING NOTES ROM VERSION CHECK ¥ This system have ROM version check function consequently key set up of when power on. (No need in open the main body) 1) Press three buttons [ENTER] , [EXIT] , and [POWER] simul- taneously, in the power off. 2) Fluorescent indicator tube indicate ROM version about 1 sec- ond, and restart system. UPDATING THE ROM (IC704) VERSION The ROM version may be updated in order to fix the bugs or add the functions. ÒAll Initialize!!Ó is displayed and internal data are automatically initialized, if the power is turned on after replacing the ROM. In this case, the user preset data and system data cannot be restored. Please notify the users of this matter. If the same version ROM was replaced for repair, not for version updating, the data are not initialized unless internal data are dam- aged. Nevertheless, to avoid a trouble, it is recommended to save inter- nal data using the Data Filer, etc. The initial version of the ROM will be Ver.1.00 part No. 8-759- 499-74. Note:Internal data mentioned above are all saved in the IC702 (CY6225LL) when the power is turned off. REPLACING THE BATTERY The built-in battery must be replaced, if ÒBattery Low!Ó is dis- played at the power ON. When the battery was used up com- pletely, internally saved data (system data, user preset data, etc.) are all cleared, and ÒExt. RAM Error!Ó ÒAll Initialize!!Ó are dis- played at the power ON, then the data are initialized to the factory setting automatically. In this case, the user preset data and system data cannot be restored. Please notify the users of this matter. Unless ÒExt. RAM ErrorÓ ÒAll Initialize!!Ó are displayed at the power ON, internal data are still saved, and in this case, internal data are kept unchanged if the battery is replaced while the power is turned on. To avoid a trouble, it is recommended to save internal data using the Data Filer, etc. This information is given to the users on page 19 of the Operation Manual. Ver 1.00 Flexible Circuit Board Repairing ¥ Keep the temperature of the soldering iron around 270 ûC during repairing. ¥ Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). ¥ Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement ¥ Never reuse a disconnected chip component. ¥ Notice that the minus side of a tantalum capacitor may be dam- aged by heat.
