s "Panel Unguarded Inter-
vals Instruction Manual" distributed to telephone
offices using panel machine switching equipment
calls out use of the Type 560 with Type 60 and
Type 67 plug-ins as a test instrument.
Although the use of a scope (or American Tel
and Tel' s procedures) is optional with the operating
company - - or the local maintenance engineer - -

Check reports that use of the scope provides much
more accurate settings than were previously poss-
ible with mechanical gauges, etc., and hence more
efficient operation of the local equipment.
Since the American Tel and Tel manual fails to
mention Tek cameras in their "available equipment"
listing,
it
might pay to haul one along if your local
telco asks for a 560demo. A telephone company will
need a scope camera of some kind for every 6
scopes or so.
