    higher tuning resolution is included in your tuner for both European use and to allow for slight intentional off-tuning, which is sometimes useful in unusual reception situations. (9) SCAN KEY (AUTOMATIC TUNING) This mode will usually be preferred for locating stations. Pressing SCAN initiates an automatic band-scanning mode which pauses for four seconds on stations, then resumes the SCAN.
  • Page 6 Holding SCAN for one second results in a FAST-SCAN mode, which, upon key release, reverts to normal-speed SCAN to the next detected station.

    (This “handshake” muting of IRIS Tuner by IRIS Preamplifier, when the Tuner is de-selected, is employed to guarantee that the “on” Tuner cannot “crosstalk” into the audio of your other selected Preamplifier sources--thus allowing you to leave the Tuner powered for maximum remote convenience.) KEY OPERATION All of the KEY functions of the Tuner panel which are...

    RECORD SECURITY As explained in the “remote” section of the IRIS Preamplifier Manual, if RECORD SECURITY is in effect (either RECORD switch is in on the IRIS Preamplifier), the Tuner will refuse all IRIS remote commands, including CLR. The Preamplifier’s red MUTE legend will remind you of this by distinctive interrupted-flashing mode.
