Hello The Net,
I just got in the counter and the fan is always ON, even with the front
panel switch OFF.
I looked in the manual but could not find anyway to change this.
The counter has the standard internal 10 MHz reference, but I will be
using a Trimble T'bolt GPS/DO for the external reference.
The fan is part of the power supply module. I can see a possible need
for it if a premium ovenized reference is always ON.
But I do not have the premium internal reference.
Is there a way to only allow the fan to be ON, if the front panel switch
is ON ? Possibly a jumper setting ?
Are there any key strokes to determine the software version, other than
a check sum ?
I do not have the standard HP serial number, with the" vintage"
(manufacturing date code) code first.
The unit was manufactured in Korea.
