Adapter socket Microphone sensitivity dial Charger daptor socket Volume controls (up & down) USING THE BATTERY MODE • The monitor will revert to battery mode during a power failure only if batteries are inserted in both units. • Batteries in the nursery unit should be changed when the green light flashes. The battery icon and the nursery icon will also flash on the parents unit screen. • Parents unit should be recharged when icon blinks and a beep sound is heard. Note:Do not use Alkaline batteries in the parents unit. HOW TO USE YOUR MONITOR • To be warned if your units are “out of range”, switch the In Range Notification ON (optional). • If reception is not clear, switch to another channel. (see instructions for changing channel in the “ICON” section). • To avoid feedback (whistling sound),keep both units at least 3 meters apart (10 feet).

Channel key (8 channels) Press to enter or exit the Channel Selection Mode. Push the channel button on the parents unit. The “--” symbol will appear along with the In Range icon which will flash. Press the channel selector (top button) on the nursery unit until the night light halo fashes. Select the channel by gently pushing on the top button on the nursery unit (you will see the channel changing on the parents unit). Once the channel is selected, press and hold the nursery unit top button to confirm selection (halo will stop flashing). Both units are always on the same channel. If the interference persists, consult the Troubleshooting section. Temporary mute key Press to mute the speaker. parents unit will not receive sound for 2 minutes. Press again to reactivate the sound before the 2 minutes are up, if desired. Up and down sound volume Increases or decreases volume on the parents unit PARENTS UNIT’S SCREEN DISPLAY Nursery unit This icon will appear and the low battery icon will flash on the screen to inform you that the batteries are low in the nursery unit. Parents unit This icon will be ON only during Channel Selection Mode. Sound This icon indicates that the sound transmission is activated.It will flash when in Temporary Mute Mode. Battery level When the icon is completely dark,the batteries are fully charged.When it is clear, the batteries are low and the parents unit needs to be placed on the charger.When the batteries are TOO LOW, a “beep” will be heard every 15 seconds . The low battery icon will flash for 30 minutes before the unit shuts itself OFF. Sound level indicator Displays the sound level on the parents unit. There are 5 sound levels. Once you've chosen the desired level with the Up and Down keys, the bars will disap- pear and will start moving according to the sound transmitted by the nursery unit. The sound level indicator bars allow you to see the level of sound in your baby’s room. The louder the sounds from baby, the more bars appear. Channel and Baby’s room temperature display When turning ON the parents unit then the nursery unit, the channel number will be displayed on the parents unit screen for about one minute. It will then be replaced by the nursery room temperat…

CIRCUIT DESCRIPTION OF AC420 A. NURSERY UNIT 1. POWER SUPPLY DC 7.5V from AC adapter or 6V battery is input and they are input to BU1 regulator to provide main DC supply to the rest of circuit. (4 pieces of AAA size alkaline batteries can be used to power up the unit instead of using AC adapter.) 2. POWER AND OUT OF RANGE FUNCTION SWITCHES BSW1 is built to control power on/off of the unit. BSW2 is built to turn on and off the function of out of range. 3. MICROPHONE SENSITIVITY ADJUST SVR1 is used for adjusting the threshold level of microphone input in order to initiate the transmission of audio to the parent side. SVR1 set a DC level for CPU detect (pin26) and this level is compared with that of pin 25 (A/D detect pin) which knows the level from microphone. 4. NIGHT LIGHT CONTROL Night light BLED1 is turned on by pressing once switch BSW3 and pressing the switch again will turn off the light 5. SOUND DETECT AND TRANSMISSION Microphone BMIC1 collects surrounding sound and the signal is enlarged by BU2-A and BU2-B. BU2-B output is also used for detecting level of input sound if it is large enough to turn on transmission to parent unit. BU4 CPU turns on audio MUTE switching transistor BQ3 for audio passing into RF module. RF TX power is turned ON by switching transistors, BQ5 for TXVCC and BQ10 for VPA (power amplifier DC) from BU4 control. 6. PILOT TONE SHAPER Pilot tone shaper is formed by BR71,19,24,27 and BC37,39,40,41 which filter the signal from CPU and forms the pilot tone into RF module. 7. BATTERY DETECT AND LOW ALERT While using alkaline battery, battery level is detected by voltage level detected at junction of BR43 and BR55. If battery is detected low, BLED2 will flash to alert user. 8. TX RF MODULE OPERATION Audio signal is input into the RF module and modulates the RF signal through DVD1. DU2 PLL is controlled by CPU BU4 and drives the TXVCO DQ1 in which transmission frequency is adjusted by tuning DVC1. Transmission frequency (926-927.6MHz) is amplified at amplifies DQ2 and DQ3 and then filtered by DC26, DC27 and DDF2, dielectric filter (927MHz). RF signal (926-927.6MHz) is radiated out at antenna DANT2 which is matched with DL3 and DC28. DANT2 is a rod antenna which is fixed on PCB and without gain.
