both Precise Time and Frequency, Inc., and the carrier responsible for
shipment. Do not discard the shipping container, which should be made
available for inspection by the carrier.

panel of the unit should be quoted in all communications.

The
ptf
1226 chassis is supplied with rack ears ready for simple

For adequate support when mounted into the rack, a rear supporting bar
or tray should be used as the rack ears are designed to secure the unit in
the rack, NOT to support the full weight of the unit.

unit operates within it’s specified operating temperature range of 0 to 50
deg. C also noting that the unit relies upon convection for cooling, so
there should be sufficient air flow to accommodate this.
