WH Check and adjustment of release lock voltage and LED blink voltage
MiCheck
(Release lock voltage | Standard | 2.46+0.1V
@ILED blink voltage Standard | 2.56+0.1V
@In case of out of standard above, adjust those as following procedure.
MiMeasuring instruments: Constant voltage D.C power source (MODEL 524B, E-1, E-2)
: Digital multimeter (Type 2508, 3476, 2507)
: Direct current tester
WiChecking procedure
1. Check the current consumption at B setting (incl'd * indication) using measuring instru-
ments as follows.

2. Measure the release lock voltage while reducing slowly the voltage of D.C power source
from 3V.
3. In case of out of standard, replace R,, (68-390KQ).
