5/17 HuneTec Confidential Proprietary COPYRIGHT ⓒ, 2011 HuneTec CO., Ltd. All Rights Reserved 5. General Operation This section describes the general operation of the following areas: - System Acknowledge The M1503 automatically acknowledges the receipt of a message by transmitting an acknowledge transmission (ACK), indicating the receipt of the message. The M1503 also transmits a negative acknowledge (NACK) when messages are not received correctly. If the transmits a NACK, the system resends the message. - Acknowledge Read message M1503 is respond automatically when the user reads the message. A message is considered read when it displays on the read screen or is moved to the personal folder. A message is considered not read when it is merely viewed on the message preview screen. - User Reply User reply is an optional feature that routes back to the calling party. The reply is selected from preprogrammed responses stored in the M1503, or multiple choice responses originating from the calling party that are included with the message. - Signature Tracking The messaging system uses signature tracking to link sent messages to their responses. Signature expiration ensures that a response to an old message does not mistakenly link to a new message with the same signature. - Registration Request Registration allows nationwide systems to track the M1503 from region to region. The system then transmits messages only to that region. Automatic registration is enabled/disabled by the allow auto-registration option. The registration request message generates on the following occasions: ▪ A valid zone change – The M1503 monitors the Zone ID field in the ReFLEX25 frame header. When the M1503 recognizes that the frame header has changed, the PIC automatically sends a registration message after a programmable delay. ▪ Power up – Upon power up, the M1503 automatically transmits a registration request.
6/17 HuneTec Confidential Proprietary COPYRIGHT ⓒ, 2011 HuneTec CO., Ltd. All Rights Reserved ▪ A change from out-of-range to in-range - When the M1503 goes out of forward—channel range, and then returns within forward-channel range, it automatically transmits a registration request after a programmable delay. ▪ Failed reply causes the M1503 to try and register 6. Paging Operation M1503 can be configured to accept alphanumeric-display, numeric-display. When a message is received, the M1503s a 2 or 12 second alert depending on M1503 programming.
7/17 HuneTec Confidential Proprietary COPYRIGHT ⓒ, 2011 HuneTec CO., Ltd. All Rights Reserved Theory of Operation The M1503ists of a Radio Frequency (RF) transceiver and a microcomputer-controlled decoder, referred to as the controller. Messages are received from an RF carrier that is frequency modulated by a coded binary sequence. The circuits in the transceiver section, through a triple-conversion process, convert the RF signal to a low frequency signal that is passed on to the controller. The controller processes the coded data using digital techniques, and controls message memory, Liquid Crystal Display (LCD), and alert tones. The controller processes coded messages, and forwards the messages to the transmitter. The transmitter section generates a modulated RF carrier signal, amplifies the signal, and then radiates the signal through the antenna. The following describes the general theory of operation for the M1503cuit descriptions, detailed functional block diagrams, and schematics for the transceiver and controller are explained in the applicable sections of this manual. 1. Operating Power The transceiver and controller circuit board obtain power from the following sources: A 3.7 volt rechargeable Li-Polymer battery Provides power to the 3-volt regulator and the transmitter power amplifier.

SAR INFORMATION THIS MODEL WIRELESS PAGER MEETS THE GOVERNMENT’S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES. Your wireless pager is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for wireless pager employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. * Tests for SAR are conducted with the wireless pager transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the wireless pager while operating can be well below the maximum value. This is because the wireless pager is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a wireless pager model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government adopted requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC for each model. The worn on the body, as described in this user guide, is 1.110mW/g. (Body-worn measurements differ among wireless pager models, depending upon available accessories and FCC requirements). While there may be differences between the SAR levels of wireless pager and at various positions, they all meet the government requirement for safe exposure. The FCC has granted an Equipment Authorization for this model wireless pager with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model wireless pager is on file with the FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid after searching on FCC ID: RNGM1503RFX Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) web-site at http://www.wow-com.com. * In the United States and Canada, the SAR limit for wireless pager used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a sub-stantial margin of safety to give additional protection for the public and to account for any variations in measurements. BODY-WORN OPERATION This device was tested for typical body-worn operations with the back of the wireless pager kept 1.0 cm from the body. To maintain compliance with FCC RF exposure requirements, use only belt-clips, holsters or similar accessories that maintain 1.0 cm separation distance between the user’s body and the back of the wireless pager, including the antenna. The use of belt-clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided. For more information about RF exposure, please visit the FCC website at www.fcc.gov.
