Battery Replacement

Always disconnect all leads before replacing a battery
or fuse.
The battery will need to be replaced when the Green LED is dimly lit.
• Remove the screws on the back cover, then open the case. Take
out the battery and replace with a new 9V battery.
(Type NEDA 1604, 6LF22, 6LR61)

Fuse Replacement

It is necessary to replace the fuse when the "A" or "C" LED indicator
on the phase rotation side shows no connection (LED is not lit when
power is applied to the A-B-C leads).
• Remove the screws on the back cover, then open the case. With
the circuit board exposed and phase rotation side on the top
(away from you), take out the defective fuse and replace it with a
fuse rated for 200mA at 250V (Cat. #2973.02).
• If the "C" LED (blue lead) did not light, replace the fuse on the
left side (unit face down). If the "A" LED (black lead) did not light,
replace the fuse on the right.
• Replace the back cover on the case.
