Its operation is described below. When this key is pressed in the radio mode (FM, MW, or LW band), the LCD panel "VF" display and Band2 pin output are inverted. When this key is pressed, the VF band is selected and 375 to 500 ms later, whether or not there is a broadcast station (IF count and SD check) and SK signal are detected. If no VF broadcast station is judged not to be present (The presence of a VF broadcast station is determined by the presence of an IF count, SD signal, and SK signal), autotuning starts from VF that frequency. When the first broadcast station is detected, that frequency is held until the autotuning key is pressed thereafter, even when there is no SK signal. When the IF count and SD check are judged to be present, the autotuning operation is the same as normal autotuning, except that the SK signal is detected after 375 to 500 ms. Autotuning (seek up) is performed automatically only when the VF band is selected by VF key for the first time. Autotuning is not performed automatically even if another tuning key (other than autotuning) is pressed. 34 PD1723GF-013, PD1723GF-213 Symbol To reset the VF band, press the Function VF key or BAND key. The VF band has 6 independent memories. The last channel is also independent. When the device is set to the tape or CD mode by TPSET or CDSET switch while on the VF band, it switches to the DK standby mode. The device also switches to the DK standby mode when the VF VF key is pressed in the tape or CD mode. In the DK standby mode, BAND all the keys, other than the key, are valid. When the DK switch is set to ON in the DK standby mode, the device switches to the DK ON mode. In the DK ON mode, radio muting (RDMUTE pin) is turned off and audio muting (AMUTE pin) is turned on. When both the SD and SK signals or one of signals are lost during VF band reception (including TAPE or CD DK standby mode), BEEP is output. The SD and SK signals are checked 512 times once every 30 ms and if there are no SD and SK signals for 256 times or more, BEEP is output. For BEEP, 120 ms ON and 120 ms OFF are output 5 times, respectively. Preset memory scan and auto store memory key. The auto store memory function is enabled when initialize diode DISAMEMO is 0. When the auto store memory is used (DISAMEMO = 0), when this key is pressed and released within 2 seconds, preset memory scanning is performed. When this key is held down for more than 2 seconds, operation switches to auto store memory operation. When the auto store memory is not used (DISAMEMO = 1), the preset memory scanning operation starts the moment the button is pressed. The preset memory scan and auto store memory operations are described below. (1) Preset memory scan operation The preset memory contents are called automatically every 5 seconds. If other than the current preset memory is being received, the preset memories are PSCAN AMEMO called from M1, and if a present memory is being received, the preset memories are called from the next preset memory (for instance, from M4 if M3 is being received) sequentially every 5 seconds. This operation is shown below. Example When FM1 band being received FM1 M1M2M3M4M5M6 Other than preset memory being received on FM1 band M3 being received on FM1 band This operation is the same for the MW bands (MW1, MW2) and LW band. 35 PD1723GF-013, PD1723GF-213 Symbol Function When the next preset memory is called at the end of 5 second hold, BEEP is output. During 5-second hold, the preset memory number display flashes at 1 Hz (duty 50 %). The "ch" display does not flash. To stop at that preset memory during 5-second hold, press this key again, or press the same preset memory key as the preset memory being received. Writing of preset memory (for example, writing to M5 during M1 hold) is also possible, but the preset memory scan operation ends when the preset memory was written. The preset memory write operation during 5 second hold is described below. M2S When the ME Description key is pressed, the device enters the 5-second memory write mode. M1 (TP1) Writing is performed by pressing a to M6 key in the memory writable mode. At the end of writing, auto preset memory scanning stops. In the memory 0 writable mode, the "ch" display flashes. If no operation is performed within 5 seconds, the next preset memory channel is called and auto preset scanning continues. If the ME key is pressed again in the memory writable mode, the memory writable mode is canceled and the next channel is called 5 seconds after the key was pressed. PSCAN AMEMO When a M1 (TP1) to M6 key is pressed for more than 2 seconds, the fre- quency currently being received is written to the preset memory corresponding to the pressed 1 key. Auto preset scanning ends when the frequency was written to the preset memory (2 seconds after the key was pressed).

Broadcast station search is performed in the up direction, starting from the frequency currently being received. If the preset memory channel which is written is receiving the current preset memory, it is incremented from the preset memory channel being received (from M3 if M3 is being received). If a channel other than a preset memory channel is being received, the preset memory channel which is written is incremented from M1. When broadcast stations are PSCAN AMEMO stored up to M6, the auto store memory operation ends. The auto store memory operation broadcast station search method in the LOCAL mode and DX mode differs as shown below. * DX mode The frequencies are searched in the up direction, starting from the frequency currently being received, and ends when the preset memories are written up to M6 or all the search frequencies were searched once.

Switching to the tape and CD mode is performed by TPSET and CDSET switch, respectively. The difference from RDON = 1 of 3.1 is that the clock is displayed even when the radio, tape, and CD modes are OFF. (1) When CE pin changed Low to High 0 CE = Low Function Stop CE = Low High MAX. 125 ms Wait Radio Tape CD Clock Only 55 PD1723GF-013, PD1723GF-213 (2) When CE pin High level Radio Clock Only Tape CD DK Standby Radio Monitor DK * ON 56 PD1723GF-013, PD1723GF-213 2.3 DESCRIPTION OF EACH MODE Mode 0 Description Backup mode. When the NOCLK switch is set to no-clock, low consumption current (400 nA max.) backup CE = Low is possible. When clock is selected, the device is set to the clock count mode. In the clock mode, the maximum consumption current is 500 A. Radio When the CE pin is High level and the TPSET and CDSET switches are OFF, the device is set to the radio mode. When the CE pin is High level and the TPSET switch is ON and the CDSET switch is OFF, the device is set to the tape mode. Tape CD When the CE pin is High level and the CESET switch is ON, the device is set to the CD mode.

VF key in the tape D*K When the DK switch is set to ON in the DK standby mode, the device enters the DK* ON mode. In the DK * ON mode, radio muting (RDMUTE pin) is turned off and audio muting (AMUTE pin) is turned on. When the tape mode is set by TPSET switch when the radio monitor mode is ON by RDMONI in the radio mode, the device enters the radio monitor mode. RDMONI The radio monitor mode is also set by pressing the Radio monitor modes. key in the tape and CD In the radio monitor mode, normal tuning operation is possible. In the radio monitor mode, radio muting (RDMUTE pin) is turned off and audio muting (AMUTE pin) is turned on. NOCLK = 0 Only clock display is performed. Clock Clock adjustment is also possible. NOCLK = 1 Function is disabled. However, since the CE pin is High level, the consumption current is 500 A TYP. 57 PD1723GF-013, PD1723GF-213 2.4 RADIO ON/OFF BY POWER POWER KEY The key is invalid when the CE pin is High level. Each time the key is pressed, the POWER pin (pin 23) output is inverted. Therefore, a circuit is configured so that the radio is turned on and off by setting RDON = 0 and turning the RDSET switch on and off by POWER pin.
