4300124 Users Guide Package Contents Wireless Intercom (2) AC Adapter (2) Users Guide Voice-Activated Wireless Intercoms Features Selectable VOX mode for hands-free communication. Lockable talk button turns an intercom into a baby monitor. Expandable by purchasing additional intercoms. Can transmit up to 200 feet line of sight. 1 Power Your Intercoms (two options) AC power:
Using the supplied AC adapter, connect the intercoms DC 9V jack to a wall outlet. Battery power:
1. Slide to open the battery compartment cover. 2. Set the RECHARGE ON/OFF switch in the compartment to ON for rechargeable batteries or OFF for alkaline batteries. If you use rechargeable batteries, the intercom will automatically recharge them whenever the AC adapter is plugged in and the RECHARGE switch is set to ON. 3. Insert four AA batteries
(not included) matching the polarity symbols
(+ and ) marked inside the battery compartment. RECHARGE ON/OFF w Warning: Never install alkaline batteries with the RECHARGE switch set to ON. Alkaline batteries can get hot or explode if you try to recharge them. Battery Notes:
We recommend AA 1.2V/2500mAh NiMH rechargeable batteries, available from RadioShack. Dispose of batteries promptly and properly. Do not burn or bury them. Use only fresh batteries of the required size and type. Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities. If you do not plan to use the intercoms for a long time, remove the batteries. Batteries can leak chemicals that can damage electronic parts. 2 Set the Channel and Sub Tone To change channel and sub tone settings, use a pointed object to set the SUB TONE and CH switches inside the battery compartment. Your intercoms have four channels to set the radio frequencies used to communicate with each other. They also have eight sub tone settings to help eliminate interference. Your intercoms must be set to the same channel and sub tone for them to communicate with each other. 1. Set each intercom to channel 1, 2, 3, or 4 as shown. 2. Set each intercom to sub tone 18 as shown. n Note:
If you want all the intercoms SUB TONE Channel CH
(Channel) to communicate with each other, set them to the same channel and sub tone. Sub tone If you want one intercom to communicate only with one other intercom, set only those two intercoms to the same channel and sub tone. If you receive occasional interference falsely triggering your intercom, you can set each intercom to a different sub tone. However, if there is frequent interference that affects the conversation or audio quality, set your intercoms to a different channel. 3 Use Your Intercoms To turn on an intercom, rotate VOLUME to the maximum volume direction until it clicks. Then adjust VOLUME to a comfortable listening level. Call another intercom:
1. Press CALL once. The TRANSMIT indicator lights. Each intercom that is turned on and set to the same channel and sub tone beeps for about three seconds. 2. Press and hold TALK and speak in a normal voice after you hear the beep. When you finish speaking, release TALK and listen for the response. Monitor an intercom:
You can set any intercom so it continuously transmits sounds from the area where it is located to another intercom. You can only monitor one intercom at a time. 1. Press LOCK on the intercom in the area you want to monitor. The TRANSMIT indicator flashes. 2. When you finish monitoring, release the lock by pressing TALK on the intercom in the area you are monitoring. TRANSMIT turns off. RECEIVE BUSY Indicator Lights when you receive a voice message or when you monitor a locked intercom. Flashes when the selected frequency channel is in use. VOX Level Indicator VOX Press for hands-free communication. Press to set the sensitivity level from low, medium, to high. LOCK Press to monitor continuously. Microphone TALK Press and hold and speak into the microphone;
release to listen. CALL Press to sound a tone
(or call) on another intercom for about three seconds. VOLUME (On/Off) Thank you for purchasing your Voice-Activated Wireless Intercoms from RadioShack. Please read this users guide before installing, setting up, and using your new intercoms. 4300124C_UG_EN_032713.indd 1-6 3/27/2013 5:46:06 PM 2 3 4 5 6 After pressing LOCK on an intercom, you cannot call or talk to that intercom until you press TALK to release the lock. 4 Use VOX Use VOX for hands-free communication. 1. Press VOX. The VOX level indicator lights. 2. Repeatedly press VOX to set the sensitivity level from low, medium, to high. n Note:
The VOX function turns off when the VOX level indicator turns off. In VOX mode, there is a short delay between when you start talking and intercom transmission. Mounting Your Intercoms You can place the intercoms on flat surfaces, or mount them on walls. To mount the intercoms, you need two screws (not supplied) for each intercom, with heads that fit into the keyhole slots on the back of the intercom. 315 16/
1. Drill two holes 315/16 inch (100 mm) apart at the same level. 2. Thread the screws into the holes, letting the left screws head extend about inch (6.5 mm) from the wall and the right screws head about /8 inch
(3.5 mm) from the wall. 3. Align the intercoms keyhole slots with the screws and slide the intercom down to secure it. 4. Rotate the antenna so it points upwards. n Note: Be sure you install the intercoms at least 10 feet away from each other, to avoid feedback from the speakers. Connecting an Audio Source To transmit audio to each intercom, use an audio cable with a standard RCA connector (not supplied) to connect the AUX INPUT jack of the intercom to the output jack of an audio source (not included). Each intercom can broadcast from a connected audio source only when the channel to which it is set to is not being used to transmit voice from one intercom to another. You can only broadcast from one intercom at a time. Adjusting VOLUME on the intercoms does not change the intercoms input sensitivity. Connecting a Weather Radio To transmit weather alerts to each intercom, connect the WX INPUT jack of an intercom to your weather radios alert out jack. Follow the instructions in the owners manual for your weather radio to create a weather alert. If you use the AUX broadcasting feature and the weather radio input at the same time, you MUST connect the weather radio alarms output to the unit that is transmitting the AUX input audio. Do not connect the weather radio inputs to a unit that is receiving the broadcast. Always connect the weather radios alarm output to the intercom you most frequently use to broadcast. If you connect an intercom to both a weather radio and another audio source and both sources are active, the intercom always sounds the weather alert first. The intercoms weather alarm will only shut off after the weather radio alerts expire or after you manually stop the weather radio alert. To avoid disturbing neighbors or pets if you are away from the weather radio, turn off the intercom or lower the volume before leaving.
