FreeHand has been designed to provide access for individuals with physical or mental dis- abilities to basic environmental control. The FreeHand will allow one electrical appliance or battery operated de- vice to be activated by touching the device itself or by plugging in an external switch such as Adaptivation's Tac- tion Pads or Pal Pads. The FreeHand uses a RF signal to remotely operate either a X-10 powerhouse module or a Wireless Receiver. Each unit is sold separately. Because the FreeHand is wireless, you are not tied down by cords or limited to a particular area. Wireless activation will allow greater flexibility and convenience for the user. Adaptiva- tion strives to offer our clients the highest quality products and support. Feel free to contact us at any time for assis- tance using your FreeHand. Operating your FreeHand Theory of Operation The FreeHand activates by sending a radio frequency (RF) signal to an Powerhouse X-10 module (also known as Lamp and Appliance Modules at Radio Shack) or a Wireless Re- ceiver. Diagram 1 helps illustrate a typical scenario. 4 Terminology RF RF stands for radio frequency. RF devices can transmit through walls unlike infared which requires line of sight. Wireless Receiver A Wireless Receiver will allow the FreeHand to control most battery operated devices and also communication aids or other assistive devices. ○○○○○ ○○○○○○ ○○○○○ ○○○○○○○○○ AC powered appliance is plugged into X-10 module Wireless Receiver is plugged into VoicePal communication aid. Wireless Receiver is plugged into a battery operated toy. Diagram 1. FreeHand sends RF to receiver. 5 Transceiver Module The Transceiver Module accepts the RF siganl from the FreeHand and will allow activation of most electrical or AC appliances. House Code The house code is the frequency the FreeHand uses to transmit to either a Wireless Receiver or a Transceiver Module. The house code must be set to the same letter on both devices. Us- ing different house codes can allow different individuals to operate their own devices without interfering with each other. Unit Code This code allows one Transceiver Module to operate up to 16 other appliance modules. The unit code on the FreeHand must be set to the same number as the number on the appli- ance module. Modes of Control Direct selection: The appliance activates for as long as the switch is pressed. Latched selection: Press once and the appliance turns on. Press again and it turns off. The latch mode is effective when a device needs to be turned on for an extended amount of time. 6 FREEHAND HOUSE UNIT SWITCH OFF CODE CODE IN DIRECT TIMING MIN LATCH TIMING SEC. OFF/Timing Knob External Switch Jack Unit Code Dial House Code Dial Mode Selection Switch Diagram 2. 7 Timed Seconds: Press once and the appliance turns on, then automatically turns off at the preset time anywhere from 1 to 60 seconds later. Timed Minutes: Press once and the device turns on, then au- tomatically turns off at the preset time anywhere from 1 to 60 minutes later. Note: The timing is adjusted using the Timing Adjustment Knob. See Diagram 2. If you wish to stop the device before the timed amount is over, turn the Timing Knob to the "OFF" position, then back to the "On" position. This will reset the FreeHand. Battery Installation 1. With the FreeHand lying face down, open the battery com- partment cover by removing the single Phillips head screw. 2. Properly insert one 9 volt battery. Adaptivation recom- mends using only Alkaline 9 volt batteries to ensure long bat- tery life. 3. Replace the battery compartment cover and secure with screw. Take care not to overtighten. Note: To conserve the batteries, turn off the FreeHand when not in use. 8 Operation for AC Appliances 1. Set the FreeHand and the Transceiver Module to the same house code. Also make sure the unit code is set to the number 1 position, unless you are plugging the applicance to be acti- vated into another Appliance Module set to a different unit code. 2. Plug the appliance you wish to operate into the bottom of the Transceiver and plug it into the wall outlet. Make sure the appliance is in the "on" position. 3. Check to make sure the wattage of the appliance does not exceed the recommended maximum amount on the back of the Transceiver Module. 4. Set the FreeHand to the desired mode of control and make sure it is turned on by moving the OFF/TIMING DIAL to the "on" position. . Press the top of the FreeHand or an external switch to activate the appliance. Note: If using other Appliance Modules other than the Trans- ceiver Module, you must still have the Transceiver Module plugged in since the FreeHand sends the RF signal to this module first. Also make sure both the FreeHand and the Ap- pliance Module are set to the same unit code number. 9 Operation for Battery-Operated Devices 1. Set the FreeHand and the Wireless Receiver to the same house code. Also make sure both have the unit code set to the same number. 2. Make sure you have inserted batteries into the Wireless Re- ceiver and it is turned on. 3. Insert th…

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 7, 2002 RE: FCC ID: Qk7fh-me Attention: I have a few comments on this Application. 1 The device uses a “Direct Mode”. The manual describes this as the appliance being on as long as the switch is pressed. The test report also states that the device is battery operated and does not connect to the AC mains. 15.231 devices cannot operate in a continuous transmission mode. 15.231 devices are limited to non-periodic, non-continuous control code transmissions only. Thus, it would not appear likely that an appliance could be directly connected to this device. Consequently, please explain how this direct mode works and how it prevents rf transmission while the switch is depressed while operating the appliance? 2 Please explain how this device meets the requirements of 15.231 to automatically limit operation so that the duration of each transmission shall not be greater than one second and the silent period between transmissions shall be at least 30 times the duration of the transmission but in no case less than 10 seconds. 3 The device is capable of operating up to 256 devices. This means that over 256 control codes are possible with this device. The test report is vague on the preliminary testing of random or selected control codes to establish which switch settings provided the worse case modulation. Please explain what measures were made to establish which control code settings provided the worse case.

Subject: FW: FW: Qk7fh-me request for info Date: Mon, 14 Oct 2002 11:02:53 -0500 From: "Doug Kramer" <[email protected]> To: <[email protected]> Dennis, Does this help on the 2 FCC applications for QK7? -----Original Message----- From: JSE [mailto:[email protected]] Sent: Monday, October 14, 2002 11:40 AM To: Doug Kramer Subject: Re: FW: Qk7fh-me request for info Doug, Below are my responses to the questions from ATCB. 1 - When in "Direct Mode," the RF transmitter does not continuously transmit. When the switch is pressed, it transmits a single command to turn ON the A/C appliance. When the switch is released, another single command is sent that turns OFF the A/C appliance. This gives the effect of the user have some sort of continuous control of the A/C appliance. Of course, the appliance is not directly connected to the transmitting device. The appliance is plugged into a third-party reciever (already been through FCC approval) that actually supplies or removes power from the A/C appliance. This reciever accepts commands from the RF transmitter. 2 - The transmitter sends 32-bits of data each time it transmits a command. Each bit takes 1.1 miliseconds, for a total of 35.2 miliseconds. After sending a command, the transmitter goes into a software loop for about 1.5 seconds where no further transmissions are allowed. This also allows enough time for the command to be processed by the reciever(s). ********************************************************************** *** This protocol used is standard X10 format. There are dozens of *** *** FCC-approved X10-compatible designs, tens of millions of units.*** ********************************************************************** 3 - Because of the X10 encoding protocol, there are always as many marks sent as nulls, and the duty cycle over any small portion of the transmission is 50%. This is independent of which of the 256 address codes is selected. I would not expect a given code to result is improved or diminished modulation as compared to any other code. I hope this helps.

FH-ME Photos (Freehand)

FH-ME Technical Description The Freehand (FH-ME) is a handheld, battery-powered RF transmitter. Its purpose is to allow users the ability to control AC appliances. The FH-ME transmitted signal is 310-MHz, and is compatible with the prolific X10 protocol. In function, the FH-ME is virtually identical to X10 key chain transmitters available at numerous retail outlets (www.X10.com). The FH-ME is physically much larger, though, to accommodate the needs of persons with disabilities. Typically, the FH-ME is used to turn ON/OFF lamps, radios, stereos, etc. in classrooms and in special education settings. The dimensions of the ABS plastic enclosure are 3.5” x 3.5” x 2.25”. The FH-ME consists of a PCB, through-hole electronics, and a 1/8-λ wire antenna. Following is a sample diagram showing a portion of the X10 RF protocol. The 310-MHz carrier is modulated by powering the RF oscillator ON/OFF. +--------+ +--------+ +--------+ +- | 9 msec | 4 msec | .55ms | .55ms | .55ms | .55ms 1.1ms | + +--------+ +--------+ +--------+---------------+ | preamble | logic 1 | logic 0 | Any given command transmitted by the FH-ME sends four logical bytes to the X10 receiver including error detection, resulting in a total transmission length of 65.8 msec. The on-board microprocessor is held in sleep mode (clock oscillator disabled) until the active switch area is pressed, whereby the microprocessor is activated, and the clock oscillator runs at 4MHz. After the X10 command is transmitted, the microprocessor returns to sleep mode until the switch is pressed again. The X10 protocol allows up to 256 appliances to be uniquely addressed. The FH-ME has two rotary switches that are used to set this address. The appliance plugged into the X10 receiver module that has the same address as the FH-ME will respond to command signals sent given that the receiver and FH-ME are in range.
