Key Digital ES381 - Manual (Page 10)

Start with the bottom counter. Hold it in one hand, and put the next
counter on top of the 1
st , the same way around. Align the stacking
connectors and when the stacking connectors are partly mated
engage the front “P” shaped clip (BNC end) on the 2
nd counter into
the “P” shaped slot on the 1 st counter.
Now, bring the back edge “P” clip (USB end) of the 2
nd counter
down until it clicks into the 1 st counter’s slot. These two counters
are now mated.
Check that as you pushed the 2
nd
counter down, the stack connector
has not been forced upward…if it has simply press it down until it
seats correctly (see picture above for a guide as to the normal
exposed connector depth after stacking). Repeat this for each
remaining counter, adding each one on top of the previous one.
The counters are now stacked.
2.3.1.2 Disassembling The Stack
Start with the top counter in the stack. Grasp the stack in one hand
and with the other hand’s thumb and forefinger, pinch between the
interface between the top two counters, near the back “P” clip (USB
end). With moderate force, the top counter will pop up and come
free. Remove the stacking connector from the free counter.
Repeat this for all counters in the stack.
