How to Operate

Power On

Press the POWER switch to ON. The Red LED, above the STANDBY/ON Push-button, lights to indicate the MR85 is in Standby Mode. To turn ON the MR85 press the STANDBY/ON push-button. Refer to figure 1.

Note: The POWER Switch is only intended to be switched OFF when the MR85 Tuner is not used for extended periods of time, like while away on vacation. During normal operation, the POWER Switch should stay in the ON position. Press the STANDBY/ON Push-button for turning the MR85 ON and OFF. When the Power Control Cable is connected to a McIntosh Control Center, A/V Multizone System Controller or Preamplifier, the MR85 Tuner will automatically switch ON and OFF.

The McIntosh MR85 is an advanced design AM/FM Tuner with many desirable performance features to enhance your enjoyment of radio broadcasts. There are three modes of tuning to an AM/FM Broadcast Station. There is Manual Tuning using the TUNING Knob; Seek Mode Station Se- lection using the SEEK π (Up) and θ (Down) Push- button(s); and Preset Station Selection using the PRESET Selection Knob.

Note: When the MR85 AM/FM Tuner is connected to a McIntosh Control Center, A/V Multizone System Controller or Preamplifier via a data connection ,the tuner functions such as SEEK, direct PRESET Selection and REVIEW of Preset Stations may be controlled by the McIntosh Remote Control and/or Keypad.

Preset Selector Switch

The PRESET Selection Switch allows selection of desired radio stations that have already been stored into memory. There are up to 9 AM and 9 FM stations that can be stored for the Tuner 1. The optional secondary Tuner 2 Module also has up to 9 AM and 9 FM stations that can be stored into memory. The PRESET Selection Switch also assists in

changing the Front Panel Alphanumeric Display from indi- cating the Station Frequency (default), to displaying per- sonalized names of your choice. Example, instead of the Front Panel Display showing Preset number 3 as “105.70 FM” it could display “JAZZ 7”. Refer to “How to Assign Presets Stations and Custom Names” for further informa- tion.

Note: The PRESET Selection Switch will not access Station Presets that have been left blank. If no Presets have been assigned, the Front Panel Display will show “NO PRESETS” until at least one station has been entered into memory. Refer to figure 2 below.

Manual Tuning

Manual Tuning is provided through the Front Panel TUN- ING Knob. Rotate the TUNING Knob clockwise to tune up in frequency, 10kHz steps for AM or 200kHz steps for FM. Spin the knob to tune up continuously. Rotate the TUNING Knob counterclockwise in the same manner to tune down in frequency. When a station is selected, the Front Panel Display will indicate (from left to right) a Preset Number, if that station has been assigned a Preset, the FM Station Frequency, the received Stations Signal Strength from 1 to 9, and a dot (located to the right of the Signal Strength Digit) if the station is broadcasting stereo.

Note: FM band indications are in Megahertz. In the US and Canada, they change frequency in 200kHz steps. The second digit to the right of the dot which displays a 0, is used for FM stations in Europe where stations change in 50kHz steps. In Europe and Japan, the AM display changes in 9kHz steps.
