Warranty and Service
4.1 Warranty
In order for the factory warranty to be valid, the
installations in a certified aircraft must be accomplished by
an FAA- certified avionics shop and authorized PS
Engineering dealer. If the unit is being installed by a non-
certified individual in an experimental aircraft, a factory-
made harness must be used for the warranty to be valid.
PS Engineering, Inc. warrants this product to be free
from defect in material and workmanship for a period of one
year from the date of purchase from an authorized PS Engi-
neering Dealer. During this one year warranty period, PS
Engineering, Inc., at its option, will send a replacement unit
at our expense if the unit should be determined to be
defective after consultation with a factory technician. The
customer is responsible for return shipment costs.
This warranty is not transferable. Any implied
warranties expire at the expiration date of this warranty. PS
Engineering SHALL NOT BE LIABLE FOR INCIDENTAL
OR CONSEQUENTIAL DAMAGES. This warranty does
not cover a defect that has resulted from improper or
unreasonable use or maintenance as determined by us. This
warranty is void if there is any attempt to dissemble this
product without factory authorization. This warranty gives
you specific legal rights, and you may also have other rights
which may vary from state to state. Some states do not allow
the exclusion of limitation of incidental or consequential
damages, so the above limitation or exclusions may not
apply to you.

channel closes. This prevents squelch closure between
words, and helps eliminates choppy intercom
conversations.
3.3 Intercom Mode Select
The center switch is a three position mode control
that allows the pilot to tailor the intercom function to
suit flight conditions. Regardless of configuration, the
pilot will always hear the aircraft radio. NOTE: If
there is a power failure to the PM1000II, or if the
power switch is turned off, the copilot will not hear the
aircraft radio. Only the pilot is connected directly to
the aircraft radio.
ISO (Up Position): The pilot is isolated from the
intercom and is connected only to the aircraft radios.
He will hear the aircraft radio reception (and sidetone
during radio transmissions). Copilot and passengers
will hear themselves and music but not the aircraft
radio traffic.
ALL (Middle position): All parties will hear the
aircraft radio, intercom, and music. However, during
any ICS or radio communications, the music volume
automatically mutes. The music volume increases
gradually
back to the original level after
communications have been completed.
CREW (Down Position) (ONLY version with
crew, part number 11908 ): Pilot and copilot are
connected on one intercom channel while the
passengers are on a separate and independent channel.
The pilot and copilot are connected to the aircraft radio
and may listen to Music #1. Passengers can continue to
communicate with themselves without disturbing the
pilot and copilot and may listen to Music #2.
3.4 Internal Recorder System (IRS)
This records the last radio messages, storing up to
60 seconds of received radio phrases. Only the pilot
will hear the playback. The last message received will
be the first one played back. This function is intended
to help the pilot determine is a radio call was meant for
him, and not to store clearance or ATIS.
To play back the last recorded message, press the
switch labeled “Playback” installed in the aircraft. To
cancel the playback, press and hold the playback but-
ton for two seconds. The next time the button is
pressed, the earlier message will be heard. If the radio
becomes active while a message is playing, the mes-
sage playback will stop. The new audio will not be
stored. Press play to restart the message you were
playing.
A radio signal of more than 1 VRMS is needed to
trigger the IRS. Therefore, if the IRS does not seem to
