Page 7: Warnings And Cautions
Warnings and Cautions WARNING The Power Amplifier Module may use semiconductor devices containing Beryllium Oxide. Dust from this oxide is toxic and, if inhaled or skin contact is made, can be hazardous to health. No danger can arise from normal handling, but no attempt should be made to break open or tamper with these devices in any way. -
Page 8: Glossary Of Terms
GLOSSARY OF TERMS A summary of common radio terms and some other terms used in this document, and their meanings, are given below. Trunking Signalling Specification relating to trunked networks for shared use. Used primarily for networks in France. Analogue to Digital Converter. Automatic Frequency Control. - Page 9 CLIM Call Limit Time; time limit on calls made. Normally this is defined by the Call Time Limit parameter but can by overridden by the TSC depending upon the setting of TSCLIM. Emergency Call Limit Timer. CLIME Closed A state where transmit and receive are not allowed until a Selcall message to open the channel has been received.
- Page 10 Digital Signal Processor. Abbreviation of Dual Tone Multi-Frequency signalling. Used to dial into Telephone DTMF networks using tone dialling. Dual Watch A facility that enables the Radio to periodically monitor another channel for a signal above squelch. Typically applications are checking an emergency channel whilst on another channel.
- Page 11 Link Establish Time A delay incorporated into the start of every selective call or DTMF transmission that allows for the finite delay of the radio equipment in responding to any radio signal. This includes both the commencement time of the originating transmitter and the response time of the receiver.
- Page 12 If inhibited from transmitting a Selcall sequence because the channel is busy then the radio can queue the Send 1 / Send 2 sequence for later transmission. When a radio unit is in Queuing mode all incoming calls are stored automatically in a queue for later examination.
- Page 13 Simplex Mode of operation whereby the radio operates as a conventional fixed channel radio outside the Trunking network. System used to prevent weak, unintelligible signals and random noise from being Squelch heard by a radio operator while still allowing intelligible signals to be received normally.
- Page 14 Trunked Mobile Radio. An audio tone is transmitted at the start of transmission to inform a relay (repeater) Tone Burst station to switch itself on to relay the transmission. Transpond An Acknowledge identity sent as a response to an individual call. TRAXYS Air Interface for the PTT Telecom Trunked Radio Network, used in the Netherlands.

Page 18: Software Versions And Naming
OFTWARE ERSIONS AND AMING There are various associated items of Software (SW) required for the SRP9100 radio and programmer to operate. This section simply defines the naming rules of the SW files to allow identification and conformity. This allows different versions of SW to be distributed and co-exist without confusion. The SRP9100 Transceiver has three items of SW for digital and analogue PMR, Trunking and Alignment. -
Page 19: Version Number
Version Number 1.5.4 This is a 3-digit number allocated by Engineering to identify the SW version. Version 1.03 Exclusions 1.5.5 The Programmer SW does not follow the above rules, as it is a PC based Program and its version number can be easily identified by starting the SW. -

Page 22: Adjustment And Alignment
DJUSTMENT AND LIGNMENT There are no internal adjustments in the SRP9100. Re-programming and alignment is performed using software tools. For testing, a special test jig is required so that the radio PCB can be powered and input/output accessible. This test jig has a dummy battery and a connector that plugs into the top of the radio so that the jig controls PTT and provides access to audio in and out. -

OFTWARE OLICY Software provided by TMC Radio shall remain the Company's property, or that of its licensors and the customer recognises the confidential nature of the rights owned by the Company. The customer is granted a personal, non-exclusive, non-transferable limited right of use of such software in machine-readable form in direct connection with the equipment for which it was supplied only. -
Page 32: Disassembly
The customer undertakes not to disclose any part of the software to third parties without the Company's written consent, nor to copy or modify any software. The Company may, at its discretion, carry out minor modifications to software. Major modifications may be undertaken under a separate agreement, and will be charged separately. - Page 33 Remove the Metal Frame Assembly (1) Use a small, flat bladed screwdriver to release the cast metal frame assembly from the bottom of the front casing. This action releases the radio PCB from the MMI PCB. (2) Gently ease the frame assembly out of the front casing taking care not to damage the two flexi-circuits. (lift the bottom of the frame so that it just clears the plastic casing, then gently slide the frame away from the top of the casing until it is released from the casing).
- Page 34 Remove the Speaker and Microphone (1) Remove the speaker retaining clip. (2) Lift the speaker / microphone assembly away from the front casing taking care not to damage the flexi- circuit. Figure 3 Removal of Speaker and Microphone Remove the MMI PCB The MMI PCB is held in place by four plastic lugs on the front casing.
- Page 35 Remove the Switch Mat The switch mat is held in place by the MMI PCB. Lift the switch mat clear of the casing. RE-ASSEMBLY Re-assembly is the reverse of disassembly. However: (1) Examine the various seals before re-assembly and replace with new items if necessary. (2) Slight outward deflection of the case walls will ease re-assembly of the MMI PCB behind the retaining lugs.

Page 37: Technical Description
TECHNICAL DESCRIPTION ECEIVER Refer to Figure 4-1. Description based on UW band Front-End Filters and RF Amplifier 4.1.1 The receiver input signal from the antenna passes through the harmonic filter and antenna switch. With the portable in receive mode, diodes D580, D540a and D541a in the antenna switch are reverse biased allowing the receiver input signal to be coupled through to the receiver front-end with minimal loss. -

REQUENCY YNTHESISER General 4.3.1 Refer to Figure 4-3. The frequency synthesiser consists of one transmitter and two receiver voltage controlled oscillators, loop filters, varactor negative bias generator, reference oscillator and an integrated dual phase locked loop device U701. 4.3.2 The PLL device contains two prescalers, programmable dividers and phase comparators to provide a main and auxiliary PLL. -
Page 42: Reference Oscillator
Tool. Adjustment of the ramp slope effectively changes the Phase Modulator gain by modification of the Schmitt Trigger switching points after modulation from the Integrator is combined to the saw tooth ramp. The divided reference signal is differentiated and discharges C744 via Q711 after which Q711 is turned off allowing C744 to recharge via constant current source Q712/Q713. -
Page 43: Control
ONTROL Refer to Figure 4-4. DSP and PLA 4.4.1 The SRP9100 transceiver operates under the control of a DSP (U201) and PLA (U300) combination that together with a number of other dedicated devices perform all the operational and processing functions required by the radio. -
Page 44: Memory
Analogue voltages to be monitored such as PLL Loop Voltage (LOOP_VOLTS), key detect (KEY_DET), battery voltage (BAT_SENSE), transmitter current (TC_CURRENT), volume level (VOLUME) and external sense (EXT_SENSE) are connected to the inverting inputs. The analogue voltages are compared with the ramp voltage as they increase and the comparator switches at the point where the input voltage exceeds the ramp. -
Page 45: Regulator U900
The Power-off operation requires the On-Off switch to be turned off for more than 2 seconds. If the On-Off switch is sensed going low by the DSP via the PWR_SENSE line, the DSP will save radio settings and then lower the PWR_OFF line, thereby turning Q900 off. Power Supplies 4.6.2 The following is a list of the SRP9100 power supplies and some of the devices and circuits they supply. -

(MMI) EYBOARD AND ISPLAY Keypad Press Detection Electronically, the keypad keys are arranged in a matrix of 3 rows and 7 columns. The rows are driven directly by two processor port signals KEY_ROW1 and KEY_ROW2 that are normally in the low state. Transistors TR910-916 generate a unique voltage on KEY_DET3 for each column. Any key in the same column generates the same voltage. - Page 47 Figure 5 Keypad Layout Backlighting The LCD and keypad backlighting LED’s, D904 to D918, are turned on by the processor port signal, BLITE, via driver TR909. 3 ~ TECHNICAL DESCRIPTION Page 4.11...
