Key to the rear panel drawing:
| 1. | Audio Output | 4. | Power Inlet |
| 2. | Antenna Input | 5. | Mains Fuse |
| 3. | MC-BUS System Connection | 6. | Power Switch |
Connecting to the System Amplifier
Connect one end of a suitable phono interconnect to the Audio Output sockets of the Cyrus FM7.5 ① and the other end to the corresponding Tuner input of the amplifier. Other amplifier inputs that are suitable for this purpose are CD or AUX inputs. DO NOT connect the Cyrus FM7.5 to the PHONO input sockets of the amplifier.
Connecting an External Aerial
This socket ② is for use with a 75Ω external FM aerial. The quality of the aerial you use will directly affect the performance of your Cyrus FM7.5. We would therefore advise that you contact an aerial installation expert in your local area or consult your dealer. In areas where FM cable transmission is available the signal strength should be adequate.
MC-BUS System Connections
Through the MC-BUS and certain ancillary equipment a highly functional integrated system with full remote control may be set up. This feature is usable if you own a Cyrus Amplifier or Pre-amplifier. Refer to the amplifier handbook for MC-BUS wiring instructions.
OPERATION (Refer to Fig.2 on the fold-out page)
Key to the front panel drawing:
| 1. | Seek | 5. | Remote Eye |
| 2. | Standby | 6. | Display Window |
| 3. | Standby Light | 7. | Manual Tune |
| 4. | Fine Tune | 8. | Presets (1-7) |
Switching On (refer to Fig.1, rear panel drawing)
The mains power switch ⑥ is located on the rear panel of the Cyrus FM7.5. This switch should be left on for normal operation, except when left unattended for a long period. In this case the mains power should be switched off or the product disconnected from the AC supply.
Refer now to Fig.2, front panel drawing.
When the Cyrus FM7.5 is in regular use and power is permanently applied, the STANDBY key ② can be used to switch the unit on and off. The standby light will show red when the Cyrus FM7.5 is in standby and green when operating. The Cyrus FM7.5 will also switch on if a preset station is selected.
Auto Tuning
Auto tuning will search automatically for stations with a usable signal strength. To begin searching, press the SEEK key ① and the Cyrus FM7.5 will scan up the frequency range, locking to the next available station. Another press will continue station scan. The station frequency and signal strength can be read from the display.
To stop scanning press the SEEK key again.
Manual Tuning
Manual tuning can be used to set to a known station frequency or to lock to a weak transmitter, not detected in auto tuning. Rotate the MANUAL tuning control ⑦ until the required frequency is shown on the frequency display. The frequency will change in steps of 50 kHz.
When a station is correctly tuned, the lock indicator will be displayed. The signal strength can then be read from the bargraph display.
Fine Tuning
Some radio stations and some cable transmissions may not be set exactly to their advertised frequency. For precise station alignment, fine station tuning is available.
Locate your station using either AUTO or MANUAL tuning. Ensure that the lock indicator on the display is showing. Press the FINE key ④. Using the manual tuning control you can now fine tune the station. When fine tuning, the bargraph display switches to show a "magic eye" centre tuning meter. For precise station tuning the black bars on each side of the display should be of equal length. Press the FINE key again to cancel fine tuning mode.
Note: Fine tuning will cancel automatically if no adjustment is made within a 5 second period.
Storing a Preset Station
Seven preset memories are available on the front panel which may be programmed with your favourite stations.
Locate the station using either AUTO or MANUAL tuning and fine tune if necessary. Press and hold a PRESET key for about two seconds until the display blinks. The station is now stored in this preset location. The Cyrus FM7.5 will retain preset stations indefinitely and requires no back up-batteries.
Note: When NEXT/PREVIOUS station preset commands are received from a Cyrus system remote control (for example, the Cyrus Audio Commander or Cyrus MR3) the FM7.5 will automatically skip all unused presets stored with the frequency of 87.5MHz.
Tuning to a Preset Station
To recall a station from the preset memory, press the desired PRESET key briefly.

| No sound from either speaker | |
| Amplifier switched off or in Standby | Bring unit out of Standby(Standby light - GREEN) |
| Tuner input of your amplifier is not selected | Select Tuner input on amplifier |
| Interconnect cable is faulty or incorrectly connected | Check interconnect cable connections |
| No lights or display | |
| No power to unit | Check that the rear panel power switch is turned on |
| Cyrus FM7.5 will not tune to stations in ‘SEEK’ mode | |
| Make sure that the antenna is connected to the 75Ohm socket on the rear panel and that stations can be tuned manually | |
| All stations have high background noise | |
| Check for the correct connection of your antenna cable and its connectors. | |
| Some stations have high background noise | |
| These may be weaker or more distant stations and therefore may require adjustment to the antenna direction for optimum receptionThere is a big difference in the sensitivity of FM antennae available on the market, and that your current antenna may need upgradingProximity to appliances with potential for high frequency radiation may cause interference with high quality reception in certain frequency bands. If you own CD players, computers and similar devices experiment by removing them from the mains and re-checking the noisy station. | |
