MODEL: DS-O4 INSTRUCTION MANUAL Di.c;cove~ Kids - 2-Way Radio ImtruClion Manual: (for bottom of 1st page with illustration) To have the most fun with YOUT 2-Way Radio, you'll want to take a look at this manual pretty carefully. Intro: Exploring your world has just gotten even more exciting now that you have the Discovery KidsTM 2-Way Radio. You can carry it almost anywhere, and all you have to do is get your frequencies set and you'll be able to talk with anyone else who has a 2-Way Radio. FCC NOTICE: - . This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable prote<:tion against harmful interference in a residential installation. This equipment generates, uses and can radiate radio fi"equency energy and, if not installed and used in accordance with the instructions, may cause hanDful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: . . . . Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radiorTV technician for help. RMATJ. This device complies with Part 15 of tOO FCC Rules. Operation is subject to the foUowing two conditions: (I ) Thi s device may not cause harmful interference, aI.t (2) this device must accept any interfa"enc;e received, including interference that may cause undesired Opef8tion. Privacy of communications any not be . . . SAFETY INFORMATION: - Your wireless hand-held portable transceiver contains a low power transmitter. When the talk button is pushed it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 500/0. In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure I guidelines with safety levels for hand-held wireless devices. CAUTION: To maintain compliance with the FCC's RF exposure guidelines hold the transmitter and antenna at least I inch from your face and speak in a normal voice, with the antenna pointed up and away from the face. If you wear the handset on your body while using the headset accessory, use only the supplied belt clip for this product and when transmitting, take it out of the belt to ensure that the ANTENNA is at least 1 inch from your body. Use only the supplied ANTENNA. Unauthorized ANTENNAS, modifications, or attachments could damage the transmitter and may violate FCC regulations. FCC W ARNlNG: This equipment generates or uses radio u-equeJK:y energy. Changes or nK>difications not expressly approved in writing may cause harmful interference and void the user-' S authority to opaaie this equipment. Adjustment to this unit or replacement of any transmitter component (aystal. sernicoldlctor. etc.) to this unit that could result in a violation of the rules. z Gettina !;taTted with ~our Di!lCOva:x Kids 2-Wav Radios: 1. Batteries Your 2-Way Radio is powered by four (4) AAA AJkaline batteries. To install the batteries, lift the spring- action hook on the back of the Radio to find a coin-screw that can be loosened by turning counter- clockwise. You will then be able to slide out the battery compartment cover and insert the 4 AAA batteries. Line up your batteries by polarity similar to the diagram below. Return the compartment cover by sliding it back in place and turn the coin-screw clockwise to tighten. DIAGRAM WITH BACK CALLOUTS (file: 2way radio back (clean» DIAGRAM OF BACK OF BATfERY PACK (file: Battery Compartment) Caution: (1) Do not mix new and old batteries. (2) Do not mix different types of batteries (alkaline, carbon-zinc, nickel-cadmium) (3) Do not use rechargeable batteries (nickel-cadmium) in this product. 2. Settings A Tumina ):OUT 2-Wa): Radio On Press and hold the Discovery Kids logo Power button until the display lights up and you hear a tone. When first turned on, the radio will be in Nonna! Operating Mode (NOM), and the LED inside the Power button will flash twice every second to let you know that it's ready when you are. SHOW LCD SCREEN OF NOM (file: DE-04LCD_ANOM) B. Tumini ):our 2-Way Radio Off Press and hold the Discovery Kids Power button until the display clears and you hear a tone. 3 C Adjustina Volume on Xour 2-Wax Radio In the NOM mode, press the UP (8) or DOWN (C) button to adjust the volume. A beep will be heard each time the button is pressed. If you hold the UP (B) or DOWN (C) button down, the volume will change automatically and you won't hear the beeps. Release the button when you are happy with the volume. D Settina the Channel Number on your 2-Wav Radio In the NOM, press the MODE (A) button once, and the CHANNEL icon will begin to flash to indicate that the radio is in channel setting mode. Press the UP (B) or DOWN (C) button to select a new channel. There are 14 channels to choose from (1-14), but both radios must be on the same channel in order to communicate. Select your channel and press the Push-To- Talk (pTT) button to confirm your new channel. Your radio will always return to NOM if you don't press any button within J 0 seconds. E S~ini the Private Conversation Code on )!our 2-Wa)! Radio Private Conversation Codes will allow you to use your 2-Way Radio without being interrupted by other radios in the area. For this to work properly, the Code that your radio is set to must be given to the friends that you want to communicate with, and all radios must be set to the same Private Conversation Code in order to work. On your Discovery Kids 2-Way Radio, you and your friends have a total of38 Pr…

Technical Description for DS04 Introduction This product is a FRS transceiver that operates on the 14 channels in the 462.5625-467.7125MHz band. Half-duplex operation is designed. When power is applied the set will be in the receive mode. Transmission is enabled by pressing the PTT (push-to-talk) key. BLACK DIGRAM OF DS04 LOUDSPEAKER 450KHZ CERAMIC FILTER 21.4MHZ CRYSTAL FILTER NOISE DETECT ANTENNA VCO&BUFFER BATTERY + - POWER AMP 2 ND LOCAL,LOCAL OSC. IF AMP & DEMOD 1 st mixer Low noise AMP ANTENNA SW RF PA DRIVER DE-EMP PLL FREQUNCY SYNTHEIZER MICROCON TROLLER LCD KEY BOARD PRE-EMP PRE AMP POWER SUPPLY As is evident in the above block diagram, this product employs dual-conversion superhet architecture for itsreceiver. The first IF (Intermediate Frequency) is 21.4MHz. The second IF is 450kHz. The local oscillator signal is PLL-synthesized to ensure accuracy and stability. A microcontroller with appropriate firmware is designed toprogram the PLL to the desirable user-selected channel for either transmit or receive. Circuit Description Receive mode The antenna is connected to the low noise amplifier Q14 via the T/R switch formed by D8 and D7, L1, C69 and C70. During reception (RX), D7 and D8 are off. The incoming RF signal is routed to Q14 via the pi-network formed by L1, C69 and C70. The amplified RF signal is coupled to the first mixer Q15. The first local oscillator signal is PLL-synthesized. Q18 is the VCO which is tuned by the filtered error voltage from the PLL chip U5. Channel selection is accomplished by sending appropriate data to U5 via a 3-wire serial bus. This is taken care of by microcontroller U1. The 21.4MHz crystal filter at the mixer output selects the desirable IF signal while rejecting other mixing products. The first IF signal is amplified by Q16 and then passed to U6 which contains the second mixer/local oscillator, IF amplifier/limiter and quadrature FM demodulator. The demodulated FM signal is filtered by the deemphasis network and low-pass filter formed by R1,R2,C25 and an internal OP-AMP in U7. The filtered audio signal is then routed to the power amplifier (U4) which drives the loudspeaker.
