BJ4-64WDB40TXWireless Chime Control

DRAFT COPY Lighted Wireless Push Button Accessory The Heath ® /Zenith Wireless Push Button Accessory works with existing Heath ® /Zenith jumper or dip switch systems. •Battery powered push button - No wires to run. •128 selectable codes allow more than one chime system in the same house. •LED lighted push bar in dark conditions. © 2002 DESA International598-1137-00 (Style may vary from illustration) Lighted Push Bar Feature Your Heath ® /Zenith wireless (battery operated) push button contains a LED (Light Emitting Diode) that will turn on in dark conditions so the push button will be more visible for your guests. This patent (pending) technology and built-in photocontrol will allow the light intensity of the push button LED to increase as the outdoor light conditions around the push button decreases. The actual time and intensity that the LED is visible will depend on the specific mounting environment of the push button. In darker environments, such as garages, carports, or covered porches, the LED will be visible a longer period of time each day or always. In very well lighted environments, the LED will be visible for a shorter period of time each day or never. In nominal conditions the bat- teries will typically last 2 years. -2- 598-1137-00 DRAFT COPY 2.Set the push button jumpers to match the chime receiver code. See “Code and Tune Setting” section. 1.Install lithium type CR2032 3 volt batteries (included). Remove back of case by pushing in tab on bottom with a small screwdriver. Make sure battery is oriented properly (see page 5). 4. Mount push button. Use either screws or double sided tape to mount push button. To mount with screws, remove back of case by pushing in tab on bottom with a small screwdriver. Attach back of case to door jamb or wall. Snap front of push button on. When attaching push button using double sided tape, make sure the surface of the door jamb or wall is clean. 3.Test range. Temporarily position push button where you want it mounted. Press push button to verify chime and push button work properly. If chime does not sound, see Troubleshooting. -3- 598-1137-00 DRAFT COPY Code and Tune Settings Code Settings Note: Most installations will not require you to change any jumpers on your chime and push button. WARNING: Disconnect chime unit from power source be- fore opening code access door. Close door and replace screw before reconnecting to power. The push button and chime communicate by using a code that can be changed by removing and/or adding jumpers on both the push button and chime. The code is factory set; however, there are 128 selectable codes that allow you to expand your system and prevent outside interference. Other wireless prod- ucts may cause interference and the system may not function properly. Follow the instructions below for setting a new code. 1. Unplug wireless chime (if applicable). 2. Open the cases and locate the jumpers on both the push but- ton and chime (See illustration on page 5). 3. The push button and chime both have eight different jumper locations. The jumper positions 1 through 7 are used for set- ting the code. 4. To change the code, add and/or remove jumpers as needed. It is recommended to only change one jumper at a time and then check to see if system is functioning properly. Note: Jump- ers in positions 1 through 7 must be exactly the same for both the push button and chime for this system to function. -4- 598-1137-00 DRAFT COPY Tune Settings Your Heath ® /Zenith wireless chime has different selectable tunes: Ding (one note), Ding-Dong (two note), or Westminster (eight note) (Available on selected Heath ® /Zenith chimes). The fac- tory setting is for the Ding-Dong tune (or Westminster, when available). This tune can be changed by following the instruc- tions below. •Ding (one note tune) Push button: Add a jumper to location 8. •Ding-Dong (two note tune) Push button: Remove jumper from location 8. Chime: Remove jumper from location 8. •Westminster (Eight note tune) (Available on selected Heath ® / Zenith chimes) Push button: Remove jumper from location 8. Chime: Add a jumper to location 8. Note: All models have both front and back door tune capabili- ties. You may purchase any Heath ® /Zenith wireless push button for a second entrance. We recommend the back door use the Ding tune and the front door use the Ding-Dong tune (or Westminster tune, available on selected Heath ® /Zenith chimes). Models that include two push buttons will come factory set for front and back doors. Decals on the rear of the push button will indicate its setting. -5- 598-1137-00 DRAFT COPY C R 2 0 3 2 + 1 2 3 4 5 6 7 8 12345678 Inside Push Button Replacing Push Button Batteries Install two lithium type CR2032 3 volt batteries.

Batteries seem OK, but the chime does not work when installed: •Do not mount chime or push button on metal or near metal studs. This reduces the transmitter range. Use 1/4" to 1/2" (6 to 13 mm) wood shims to move chime or push button off metal surface. •Concrete floors may reduce range. Move chime away from floor. •Try locating chime closer to push button. Push button light (LED) is “ON” or “OFF” all the time (see page 1). The range of the wireless chime can vary with location, temperature and battery condition. -7- 598-1137-00 DRAFT COPY No Service Parts Available for this Product Technical Service (Do Not Send Products) If you experience a problem…

DRAFT COPY FCC ID: BJ4-64WDB40TX IC: 3984A-6440TX This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Lighted Transmitter Product Description Heath®/Zenith Model number: SL-6440 & SL-6441 FCC Model designation: 6440TX IC #: Canada: 3984A-6440TX SL-6440 (LE-6440) & SL-6441 Description Model SL-6440 (LE-6440) & SL-6441 are wireless lighted transmitters that contain the same PCB and circuit design, which is FCC Model designation 6440TX, with different plastic case designs, color of LED, and/or packaging. Two CR-2032 lithium 3-volt batteries power this unit. This input power is internally regulated in the encoder IC T-99. The pin header is the selector to control the coding for the T-99 encoder. The output of the encoder chip goes through the oscillator/modulator stage. The oscillator is tuned for 315M Hz. The encoded signal is then sent through the “paper clip” antenna mounted on the PCB and the RF output is transmitted into the air. A photo resistor, super bright LED, and biasing circuit operates independently from the RF circuitry to provide light in dark conditions.
