Secondary Initial Paging System. This bit is used to disable internal handset speaker when adding V. The ouput of Manua is split into two signals. Authorized distributors may opt to receive additional training to become authorized to perform limited component repairs. Motorola, the Motorola Logo and all other trademarks identified as such herein are trademarks of Motorola, Inc. Automatic call processing tests can be performed while the phone is in its power-up state.

Turan The data on the forward control channel generally provides some basic information about the particular cellular system, such as the system ID and the range of channels to scan to find the access and paging channels.
This operation forward biases diode CR When enabled, the user can place an Extended System in auxiliary alert mode and be notified of incoming calls via headlights, horn etc. In the FCC expanded the cellular spectrum Expanded Spectrum from a total of channels to channels, allowing for an increase of 83 voice channels for each carrier.
The telephone powers up and runs a self-test. In standby mode, the mobile telephone will automatically transmit to acknowledge a call if it is not turned off. Once the tab is released, peel off and slide the cover away from the flip.
Frequency error is displayed. End-to-End Signaling Bit A5. When set to 0, audio is routed to the accessory speaker of the transportable. U will receive channel information via manuak SPI bus and adjust the frquency of U by varying celullar voltage level to the input of U Parameters such as operating channel, output power level, muting, and data trans-mission can all be selected by entering the corresponding commands.
When the central controller switch signals the mobile regarding the new Figure 4. When new data is entered via the keypad celjlar display scrolls from left to right. The CRC is used during the decoding process to determine the validity of the class I bits. C is used to add stability to the AGC circuit. The telephone scans all twenty-one control channels.
U uses a parallel interface bus. The 7th-order odd polynomial minimizes ,anual amount of spectral splatter and is realized in software. Make sure you can see top of tool in seam. Motorola P Service manual Test Connections The diagram below shows the recommended connections for testing transceivers.
The resultant analog waveform is filtered by a 5th-order low-pass switched-capacitor filter and a two-pole, twozero continuous-time filter to remove aliases.
If the signal received from the cellular telephone is higher than the prescribed limit such as when the unit is very near the cell sitethe subscriber unit will be instructed to step down to a lower level. If the reading you are getting shows gain positive number, you may need to zero the power meter.
Remove the flip by pulling up on the hinge pin side and out on the other side. This is called Autonomous System Registration and, like paging channels, is used to improve paging efficiency. In digital mode, because of its IQ modulation scheme, PA linearity is a more important factor than efficiency. Motorola Confidential Proprietary CS 2. When set to v, the user may access repertory by a one or two digit send sequence speed dialing.
DTMF deviation should be measured on the radians scale; use key five looking for 9 radians. In either case, once the hand-off has been accomplished, the newly assigned cell site then alerts the switch that the handoff has been completed, and the old voice channel is dropped. Model and Kit Identification Motorola products are specifically identified by an overall model number on the FCC label.
Refer to the RX troubleshooting section for radios not within the pass specifications. For this reason, a voltage c charge pump circuit is provided. Channel Numbers are represented on the display as AA Transmitter control logic — Transmitter keying and frequency band selection. Then the 10 KHz signaling tone DST message is terminated to alert the central controller that the user has answered.
On an AMPS channel the hand-off is executed by interrupting the conversation with a burst of data called blank and burst containing the new voice channel assignment. Bits enter display on the right and scroll to left. Most 10 Related.

Fekasa Put the Test Set in Active state by selecting Active from the list on the left side of the screen. No part of this manual may be duplicated in any form without the express written permission of Motorola. Au dio Path Sinad measured on the communications analyzer must be more than 12dB. You can also use Digital Call processing to make these measurements. End-to-End Signaling Bit A5. The voice path is celuar while sending ST.
Taukree The cellular telephone acknowledges with a 10kHz signalling tone burst for 1. Bit not used Bit B4. Crlular such as operating channel, output power level, muting, and data trans-mission can all be selected by entering the corresponding commands. Then the signal is prescaled and sent through a phase lock loop circuit for frequency locking. For the stubby antenna you can use your fingers to turn the antenna clockwise until it locks into place. AKG CS MKII Service Manual download, schematics, eeprom, repair info for electronics experts In either case, once the hand-off has been accomplished, the newly assigned cell site then alerts the switch that the handoff has been completed, and the old voice channel is dropped.
