Enhancement of countermeasures against "E1-00" 
communication trouble when turning on the power 
1. Model Name
 AR-M150/M155, 
AL-1556/1566 
2. Symptom
 
When the power of the main unit is turned on, an IMC communication port trouble of 
“E1-00” may occur in rare cases. 
3. Description
 
To make enhancement of countermeasures against "E1-00" communication trouble 
when turning on the power, the following processes are executed.  
(1) One resistor (VRS-CZ1JD103J, location No. R240) attached to the MCU PWB is 
removed. (See below.) 
(2) A resistor (1k
Ω) is additionally inserted between point A on the MCU PWB side 
(GND) of the capacitor (VCKYCZ1CF104Z, location No. C138) attached to the MCU PWB 
and point B of 2PIN of location No. CN40. (See below.) 
Note: These countermeasures are applied to the MCU PWB’s having "●" mark on the 
right upper side of the lower two digits of the parts code, including the MCU PWB's 
having old-version parts code.

4. Action
 
Implementation from January 2007 production: ("●" mark is added to the right upper 
side of the lower two digits of the old version parts code of the MCU PWB.) 
Implementation from February 2008 production: (The pars code of the MCU PWB will 
be changed. )
