ON/STANDBY button The unit works 2-3 seconds after this switch is turned on. Whenever the power operation switch is in the STANDBY state, the apparatus is still connected on AC line voltage. Please be sure to unplug the cord when you leave home for, say, a vacation. Remote control sensor (REMOTE SENSOR) This sensor receives the infrared light transmitted from the wireless remote control unit. For remote control, point the wireless remote control unit to the sensor. Some of the functions can be operated with the remote control units included with DENON pre-main amplifiers and AV surround amplifiers.

Display mode selector button (DISPLAY) This button is used to select the display mode. The mode changes as follows each time the button is pressed:

• Clock time (CT) The following may be displayed if the signals are weak or no RDS service is available. This is not a malfunction. “NO PS” “NO PTY”

NOTE: The programme type, programme service name and clock time are not displayed in the MW (AM) band. “NO TIME DATA” may be displayed within the first minute after a station is tuned in, but this is not a malfunction. If time data is being broadcast, the time can be displayed after one minute has passed.

Selects FM or MW. Use this button to select the memory blocks, A (1 to 8), B (1 to 8), C (1 to 8), D (1 to 8), or E (1 to 8). For PTY search, use this button to select the program type. When writing station names, use this button to set the writing position. MEMORY button Frequencies and station names can be stored in the memory. When this button is pressed, the “MEMO” and “CH” indicator on the display flashes for 10 seconds. Use the SHIFT/PTY button and the preset channel buttons during this time to designate the desired preset channel. TUNING/PRESET control This control is used in conjunction with the TUNING/PRESET button i. In the TUNING mode, the reception frequency is tuned up or down. Turning the control in the clockwise direction tunes the frequency up. Turning the control in the counterclockwise direction tunes the reception frequency down. In the PRESET mode (when “PRESET” !3 is lit in the display), the selection of the preset channel is moved up or down. The AUTO TUNING operation cannot be used when in this mode. When writing station names, use this control to select the letters. (Refer to Page 5.) TUNING/PRESET button Each press of this button toggles the operation mode of the TUNING/PRESET control u. In the PRESET mode, the “PRESET” !3 indication of the display is lit.

This button is used to turn EON TA mode on or off. (Refer to Page 11.) This button is used for displaying radio text messages. When this button is pressed while the station currently tuned in is offering a radio text message service, the message scrolls on the display. This mode turns on and off each time the button is pressed. Search character mode button (SEARCH/CHARACTER) This button is used for the RDS search (refer to Page 10), PTY search (refer to Page 11) and TP search (refer to Page

11) operations, and to input the station name (refer to Page

Tuning mode button (AUTO/MANU) This switches between auto and manual tuning. Auto tuning: (The “AUTO” indicator lights.) When the TUNING/PRESET control u is turned in this mode, auto tuning starts and tuning stops automatically when a broadcast station is found. Auto tuning is used to receive FM broadcasts in stereo. Depending on the mode of the broadcast and the strength of the signal, auto tuning will automatically switch the receiving mode to stereo or monaural. During tuning, the frequency is automatically tuned up or down. Manual tuning: When the TUNING/PRESET control u is turned in this mode, manual tuning is performed until the control is released. CAUTION:

1. Whenever the ON/STANDBY button is in the STANDBY positon, the unit is still connected on AC line voltage.

Please be sure to unplug the cord when you leave home for, say, a vacation. 2. Noise may be generated if a near-by television set is on during MW, FM broadcasting reception. The tuner should be used as far away from a television as possible.

3. Effective period of memory back-up is about a week under normal temperature.

ENGLISH The broadcast is received in monaural regardless of the mode of the FM broadcast. The reception mode should be set to “MANUAL” when there is noisy reception of stereo broadcasts (which are indicated by the lighting of “AUTO”) and also when the signal is weak. During tuning, the reception frequency is tuned up or down only when the TUNING/PRESET control knob is operated.

Preset channel button (1 ~ 8) Use these when presetting and recalling stations. Also use these with the SHIFT/PTY button to use a total of 40 preset channels, A (1 ~ 8), B (1 ~ 8), ... E (1 ~ 8). REAR PANEL
