PANEL KEY (K0/K1)
(Panel key of main unit) [Remote control code: ]
A/D of the key fails to function properly when the standard
value is deviated by ±8. In this case, check the constant of
partial pressure resistor, solder condition, etc. Refer to
table.
(Reference voltage: 5 V=100 %)

IMP SW/POWER LIMIT
(impedance/power limiter detection)
IMP: Not applied to these models.
PL: Power limiter detection value
The voltage value of pin No. 92 of IC451 is dis-
played, using 5V/256 as standard.
The port (No. 3) output is controlled by using the in-
put voltage value of pin No. 92 of IC451.
