RH-128 Care and maintenance

Care and maintenance

This product is of superior design and craftsmanship and should be treated with care. The suggestions below will help you to fulfill any warranty obligations and to enjoy this product for many years.

Keep the phone and all its parts and accessories out of the reach of small children.

Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that will corrode electronic circuits.

Do not use or store the phone in dusty, dirty areas. Its moving parts can be damaged.

Do not store the phone in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics.

Do not store the phone in cold areas. When it warms up (to its normal temperature), moisture can form inside, which may damage electronic circuit boards.

Do not drop, knock or shake the phone. Rough handling can break internal circuit boards.

Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone.

Do not paint the phone. Paint can clog the moving parts and prevent proper operation.

RH-128 Battery information

Battery information

Note that a new battery's full performance is achieved only after two or three complete charge and discharge cycles!

The battery can be charged and discharged hundreds of times but it will eventually wear out. When the operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.

Use only batteries approved by the phone manufacturer and recharge the battery only with the chargers approved by the manufacturer. Unplug the charger when not in use. Do not leave the battery connected to a charger for longer than a week, since overcharging may shorten its lifetime. If left unused a fully charged battery will discharge itself over time.

Temperature extremes can affect the ability of your battery to charge.

For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time to time by leaving the product switched on until it turns itself off (or by using the battery discharge facility of any approved accessory available for the product). Do not attempt to discharge the battery by any other means.

Use the battery only for its intended purpose.

Never use any charger or battery that is damaged.

Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip or pen) causes direct connection of the + and – terminals of the battery (metal strips on the battery) for example when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery or the connecting object.

Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce the capacity and lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°F). A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged. Batteries' performance is particularly limited in temperatures well below freezing.

Do not dispose of batteries in a fire!

Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as household waste.

CDMA RxAGC Calibration

Supported receiver calibration items are the following: CP DB HWD PCS RxAGC CP DB HWD PCS RxAGC Freq Chan Adj Note: Before starting the RxAGC Calibration, the Rx date must be set empty. Otherwise the calibration value may not be correct.

CDMA RxAGC Baseline

CDMA RxAGC Baseline overview

The basic mechanism for calibration is to provide a signal of known power at the antenna, allow the RxAGC to settle, and make note of the resulting RxAGC PDM value. In this way, the “settled” value of the PDM for a given Rx power is known.

Calibration Procedure

A. Start with reset system (PS power down, reset). B. Click on CP Enable/Disable and CP Power Down/Up. Let the CP disable and power down.

C. Set the channel. Set the control mode to Manual, and the band to the target band.

D. Set the test set frequency channel to the test frequency. For the first data point, enter the channel used to calibrate the Rx AGC. Then set the test set transmission power to a desired power which is in the Rx highest gain. The Reference Level is -99dB. E. Initialize the calibration RxAGC gain state by clicking on DSPM Rfc Dagc. Set gain state to highest gain.

F. Click on DSPM Spy Enable/Disable.

COMPANY CONFIDENTIAL

Issue 1 Page 2-36

RH-128

Service Software Instruction

The Spy windows become active, and display the current Tx and Rx status.

G. Get the RxDAgc Value Bitsel and the RxDAgc Value Gain. Write those calibration parameters together with Reference Level to the non-volatile area of flash memory. To confirm the new calibration, first update the Flash by either power cycling the UUT or by using the CalMode Select with the NVRAM option.

H. Calibrate the Gain offset. Set the test set transmission power to the desired power which is between the switch point of each gain level. Calibrate the gain level from the high gain to low gain. Set the calibration RxAGC gain state by clicking on DSPM Rfc Dagc.

I. Get the received power form the Spy window. For example, if the BS power is -85dBm, and the gain state is 3, we get -96dBm from spy window. The offset of gain 4 to gain 3 is -85 – (-96) = 11dBm. Write the calibration parameters to the non-volatile area of flash memory. Confirm the new calibration result. J. Iterate steps H - I for all desired calibration points.

CDMA RxAGC Frequency Channel Adjustment

About CDMA RxAGC Frequency Channel Adjustment

This procedure is performed at only one power setting. This procedure assumes that the baseline RxAGC calibration table has been loaded into NVRAM. However, if the calibration application (running on a PC) stores the RxAGC tables from Section 7.2.1 in PC memory, then the PC Application can interpolate dBm power values from the PDM value returned by Debugtool. More details are provided below in the steps below.

CDMA RxAGC Frequency Channel Adjustment Procedure

Issue 1 Page 2-37

COMPANY CONFIDENTIAL

RH-128

Service Software Instruction

A. Perform the procedure at “nominal” or room temperature. B. The baseline RxAGC calibration must have already been completed. C. The RxAGC frequency channel adjustment, and temperature adjustment tables must be zeroed. D. Connect the antenna to CDMA test set. E. Reset the UUT, start Debugtool, and do not press the Power key on the Virt MMI (i.e., PS should be off and LID reset). Send the message CP Enable, with Disable option. F. Set the test set Transmission Power to a desired power point (-100 dBm is a suggested value). This is normally a point that is calibrated during Rx AGC calibration. G. Set the test set frequency channel to the test frequency. For the first data point, enter the channel used to calibrate the RX AGC. H. Set the frequency channel to the calibration frequency using the CP PLL Channel Config. For the first data point, enter the channel used to calibrate the RX AGC.

CDMA TxAGC Baseline

CDMA TxAGC Baseline overview

The basic mechanism of the calibration is to transmit a signal at the antenna port with a certain PDM setting, the power of which is measured by a power meter, spectrum analyzer, or CDMA test set. The PDM setting and resulting power are then recorded. Care should be taken to provide enough calibration points near maximum power to ensure accurate transmission power at this level.

CDMA TxAGC Baseline Procedure

A. Perform the procedure at “nominal” or room temperature. B. The baseline RxAGC calibration must have already been completed. C. The RxAGC frequency channel adjustment, and temperature adjustment tables must be zeroed. D. Connect the antenna to CDMA test set. E. Reset the UUT, start Debugtool, and do not press the Power key on the Virt MMI (i.e., PS should be off and LID reset). Send the message CP Enable, with Disable option.

F. Set the frequency channel to the calibration frequency using the PLL Channel Config. This is the baseline frequency, since the frequency compensation table is not active. Set the Control mode as Manual, the band to target band.

G. Initialize the TxAGC PDM (HW Val in the box below) with a suitably low known value, to prevent a potential surge of Tx power when the transmitter is turned on in the next step. Use the DSPM Tx AGC Config. Set the Mode as Manual, the Method as HW_Value, the Hyst as current state.

N. Repeat steps F – M for all desired gain points.

CDMA TxAGC Max Power Limit Frequency Adjustment

CDMA TxAGC Max Power Limit Frequency Adjustment overview

In order to perform this calibration, the other Tx AGC calibrations should have already been performed. This procedure is performed for only one gain state, the highest gain stage, since this table only applies to max power.

CDMA TxAGC Max Power Limit Frequency Adjustment procedure

A. Baseline TxAGC calibration tables must be loaded. B. The Tx Limit Freq Chan Adj table must be cleared (write zeros in the DBM template). C. This procedure is identical to the procedure described in above section, but must be performed at the Max Power Level. D. Write calibration parameters to the non-volatile area of flash memory.

 RF connector failure

The RF connector fails when it does not properly connect RF input terminal to RF output terminal during SMT. If this happens the antenna gain degrades by 25 dB. Check this failure by measuring the resistance value between the input and output of RF connector, if the value is close to zero, replace the RF connector.

Note:

Do not insert RF cable to RF connector when testing the resistance value. Because the RF connector

is also a switch, when RF cable is inserted, RF output is disconnected from RF input.

z RF input terminal – connect to duplexer. z RF output terminal – connect to the antenna pad through antenna match circuit. z RF connector terminal – connect to RF coaxial cable.

The CP external-memory interface supports 3.0V or 1.8V, the address bus supports 16-bit address which can support three to six external devices via chip selects. CBP 5.0 includes 48 GPIOs and interrupts, some of which are multiplexed with other functions. All GPIO pins are in input state by default and use a large pull-up or pull-down resistor value to minimize the current drain. The USB port supports data rates of up to 12Mbps, the USB analog drivers and 48.00MHz PLL are integrated into CBP 5.0, the control processor manages the USB function. Two independent serial-peripheral interfaces are provided on CBP 5.0: one is for RF control and the other is for general-purpose use. The R-UIM interface supports 3V UIM cards and consists of five pins, these pins are multiplexed with another function. The CP manages the R-UIM function.

Five independent PDM DACs are supplied on the CBP 5.0 chip.

Three of the outputs are dedicated to radio-control signals for Rx automatic gain control (AGC), Tx AGC, and automatic frequency control (AFC). The fourth and fifth PDM outputs are spares. The PDMs are 12-bit DACs and have a guaranteed output range of 0.2 V to 2.5 V.

The 12-bit auxiliary ADC supports eight independent external channels on pins AUXADC [7:0]. There are also eight internal channels used to measure internal analog voltages. The input voltage range is

0.2 V to 2.7 V. The conversion time is 156 µsec. The typical uses of the external auxiliary ADC channels include: Tx RF power measurement, battery voltage, and temperature sensors.

Baseband Description and Troubleshooting

Power Up

The mobile terminal uses the power key and a charger to power up.

Power Key

When the power key is pressed, the PMU enters the power-up sequence. Pressing the power key

causes the POWER_ON pin to VBAT. The POWER_ON signal is not part of the keypad matrix. The

power key is connected to the PM. This means that when the power key is pressed, an interrupt will be

generated to the CBP in order to power on the CBP. The CBP reads the PMU IC’s interrupt register and

notifies that it is a KPADPWR_N interrupt. The CBP reads the status of the POWER_ON signal using

the PMU’s (I2C) control bus. If the POWER_ON signal stays High for a certain time, the CBP accepts

this as a valid power-on state and continues with the software baseband initialization. If the power key

does not indicate a valid power-on situation, the CBP powers off the baseband.

Charger

Charging is controlled by start-up charging circuitry in order to detect and start charging in case the

main battery is not full and the PMU has no supply.

Power Off

While the PS_HOLD signal from the CBP is high, and the PMU IC is in power-on status. The PMU

continually monitors three events that could trigger a power-off sequence:

z The CBP drives the PS_HOLD signal low responding to the pressing of the keypad power button.

z Battery voltage drops below power off threshold (Battery Voltage < 3.2 V).

z The PMU IC die temperature exceeds its “severe” over-temperature threshold.

Clock Distribution

The CBP derives its internal clock from two clock inputs, VC-TCXO and SLEEP_CLK.

The main clock signal for the baseband is generated from TCXO.

(Temperature-compensated crystal oscillator) The CBP’s TCXO clock input supports the frequency 19.2

Issue 1

COMPANY CONFIDENTIAL

Page 5-9

RH-128

Baseband Description and Troubleshooting

MHz +/-2ppm. An integrated PLL and digital divider inside the CBP are used to create the required clock

for the system.

The SLEEP_CLK provides a 32.768 kHz +/-20ppm clock source to drive the CBP controller into sleep

mode. At this mode, most of the CBP is powered down and the TCXO is disabled.

Power Distribution

In normal operation, the baseband is powered by the mobile terminal‘s battery pack. The battery pack

consists of one lithium-ion cell with a capacity of 860 mA and safety and protection circuits

The PMU ACT5805 IC controls the power distribution for the whole mobile terminal, which includes the

baseband and the RF regulators, but excludes the RF power amplifier (RF PA) which drains power from

the battery directly. The battery provides power directly to the following parts of the system:

z PMU ACT5805

z RF PA

z Vibrator

z Keyboard & LCD backlights

z Audio Amplifier

The heart of the power distribution is the power control block inside the PMU ACT5805. It includes all

the voltage regulators and feeds the power to the entire system. The PMU ACT5805 handles hardware

power-up functions so that the regulators are not powered on and the power up reset (NRST) is not

released if the battery voltage is less than 3.2V.

The baseband is powered by the following PMU ACT5805 regulators:

VC-TCXO

The CBP device integrates a phase-locked loop from the TCXO clock input.

The PMU optimizes TCXO operation that enables and disables appropriate circuits in the proper

sequence. The controller is enabled by the OSC_EN signal from the CBP. When the selected transition

occurs at OSC_EN, the controller quickly enables the TCXO regulator and the input buffer, and begins

counting SLEEP_CLK pulses. Within an initial power on period, the TCXO will be stabilized to its own

calibrated frequency. This initial period, in units of 32.768 kHz clock pulses, is programmed into a timer

within the controller. When the timer expires, the output buffer is enabled. It synchronizes with the

TCXO input such that the TCXO_OUT signal is glitch free, only valid TCXO pulses are output.

SLEEP Crystal Circuit for 32.768 kHz

The 32.768 kHz crystal oscillator is the primary SLEEP clock source when TCXO clocks are disabled to

save power.

 Display and Keypad

The mobile terminal uses light-emitting diodes (LEDs) for liquid crystal display (LCD) and keypad

illumination. There are two white LEDs for the LCD and six LEDs for the keypad. KEYPAD_LED is

the signal used to drive keypad LEDs. LCD_BL_EN is the signal used to drive LCD LEDs. The

mobile terminal uses a color LCD. The interface uses a parallel bus to transfer the Command/ Data

between CBP and LCD.
