(ii)1 Introduction and Getting Started Congratulations on selecting the TLA 850 alphanumeric pager from Multitone. Your pager has all the features you expect of a top class product yet it retains simplicity of operation through the superbly designed user interface and icon menu selection. This guide will describe the operation of the product and ensure that you receive the full benefits of paging with the TLA 850. On the back of your pager you will find the battery cover. Press down on the centre tab while sliding the battery cover outwards to remove. Insert the battery into the spring end first so that the + symbol on the battery is aligned with the moulded + symbol in the battery compartment. Carefully slide the cover back into position. Switching the Pager On To turn the pager on press and hold the •> button for one second. A short alert will 2 14:24 23.03.98 sound and the pre-programmed switch-on message will be displayed. After one second the time and date will be shown. This is the standby screen: Standby Screen Status and Operating Symbols The standby screen shows the current time and date. It also shows if there are unread messages, whether audible or vibrate alert is selected and, if appropriate, gives low battery and out-of-range warnings by displaying the following symbols: Status Symbols 14:26 23.03.98 3 From the standby screen press •> to enter the pager options screen.

The case is constructed in two main parts, the case front and the case back. A cover on the back of the TLA 853 provides access to the battery compartment. The two boards in the case are: a)The Radio Board which has the Dual Conversion Receiver, the POCSAG Decoder, the 1 Volt regulator and the audio alert output circuit and transducer. b)The Decoder Board which has the microprocessor, the EPROM, the SRAM, the Liquid Crystal Display Module, the LCD illumination lamp, the vibrate motor and the primary and backup power supplies. The block diagram of the functional areas of the TLA 853 is shown in Figure 1. 2 The RF signal enters the aerial and is fed to the dual conversion superheterodyne receiver. The signal is demodulated from RF to AF, converted to digital format and is then fed to the decoder. This results in the received data activating the memory, display and the selected audible alert or vibrate alert. To prolong the life of the battery, the receiver operates with battery economy mode. When the unit is in standby mode, the receiver is powered up at regular intervals (equivalent to once per batch) to allow the POCSAG decoder to search for pre-amble. While the unit is receiving preamble on its allocated channel, the receiver remains powered up. This allows the POCSAG decoder to search for a SYNC word. When the SYNC word is found, ‘batch lock’ is acheived. In batch lock the receiver is only powered up during the allocated frame to allow the POCSAG decoder to search for its address. If the address is found, the receiver stays ON for the duration of the message. RF AMPLIFIER TR403 MIXER AE401 AE402 2nd OSC. MIXER 455kHz TR401, TR402 45 MHz CER FL402 IC401 MIXER, IF AMP & DET.

RXEN LOWB 3 Figure 2: Receiver Block Diagram 2DUAL CONVERSION RECEIVER The incoming RF signal is received by the aerial AE401/AE402 which is tuned by CV404. Capacitors C401 and C441 provide matching to RF amplifier TR401, TR402. The amplifier, typically, yields a low noise gain of 10dB. R401, R402 and TR407 provide DC negative feedback. 4 Output from the RF amplifier passes through an image filter which provides these functions: a)Attenuation of the first image frequency. b)Attenuation of signals outside the required band. c)Matches the output impedance of the RF amplifier to the input impedance of the mixer stage. C406, L401 and CV407 form a parallel tuned circuit with the resonant frequency adjusted for minimum loss at the frequency of operation. C428, CV406 and L407 also form a parallel tuned circuit adjusted for minimum loss at the frequency of operation. In addition, C428 and L407 form a series resonant circuit with the resonant frequency close to the first image frequency. This gives approximately 40dB of attenuation at the image frequency. The local oscillator comprises transistor TR410, crystal XL402 and associated components. Frequency adjustment is by CV405. The local oscillator frequency is calculated as follows: carrier frequency - 45MHz fx = 3 where fx is the crystal frequency in MHz. The collector of TR410 is tuned to the third harmonic of XL402 by L411 and C459. The circuit provides the correct Local Oscillator frequency and reduces the level of 2nd, 4th and higher harmonics. The two tuned circuits, L413, C463 and L415, C464 give further filtering of unwanted harmonics. The mixer circuit, TR403 and associated components, receives the output of the image filter. This is mixed with the local oscillator output to produce a 45MHz product which is selected by the resonant circuit L406, C451. The 45MHz output passes through a monolithic crystal filter, FL401, which has a bandwidth of ±7.5 kHz at the -3 dB points. The output from FL401 is fed to IC401 pin 24. IC401 is a combined mixer/local oscillator/IF/detector. The second oscillator runs at 44.545MHz and, with the exception of XL401 and its associated components, is built into the IC. As the second oscillator is not trimmed, small frequency errors are absorbed when tuning the first local oscillator. The input at pin 24 is applied to the internal second mixer, and is mixed with the second oscillator output to produce a 455 kHz 2nd IF signal at pin 3. The IF signal then passes through two ceramic filters FL402 and FL403 which remove unwanted mixer products and provide further selectivity. The output from FL403 is split: one output connects through C450 to pin 6 of IC401 and the IF amplifier; the other connects to the Received Signal Strength Indicator (RSSI) circuit in IC401 through C419, R407 and pin 5. 5 Due to the characteristics of filters FL401, FL402 and FL403, the signal at the input to the IF amplifier has amplitude modulation (AM). The AM must be removed before the signal reaches the detector stage. This is performed by the IF amplifier in IC401 which has very high gain and is designed to limit the amplitude of the signal to remove the AM component and give a ‘square’ output. C479 and C480 provide de-coupling for the IF amplifier. The output from the IF amplifier passes to the detector in IC401. This circuit is a Quadrature Demodulator which has two inputs. One input connects directly to the IF amplifier, the other receives the signal from the IF amplifier through a phase del…

1 Multitone TLA 853 - Features & Specification INTRODUCTION The Multitone TLA 853 Radio Paging Receiver is a UHF receiver which receives alpha- numeric messages sent in CCIR Radiopaging Code No.1 (RPC1). The front panel of the unit has a Liquid Crystal Display (LCD) to display messages and other information. The three buttons on the front panel are used to control the functions of the unit. The LCD can show a maximum of two lines of 20 alphanumeric characters. If a message is longer than 40 characters, the excess is stored. The front panel buttons are used to transfer the stored part of the message to the screen as required. Message alert is provided by an audible beep tone or by the unit vibrating. The buttons are used to select the preferred alert. Power for the unit is supplied by a single AAA battery. A door on the rear of the unit gives access to the battery. A back-up supply for the unit is available when the battery is changed. The back-up supply is provided by a large-value capacitor mounted on the decoder board in the unit. The capacitor, when fully charged, can maintain data in the unit for 60 minutes. The unit case is a two-piece plastic moulding secured by two cross-head screws. A lanyard is supplied with the unit which can be fastened to the case and the attached clip used to secure the unit to a suitable object.
