WARNING

This service information is designed for experienced repair technicians only and is not designed for use by the general public. It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service a product. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product or products dealt with in this service information by anyone else could result in serious injury or death.

IMPORTANT SAFETY NOTICE

There are special components used in this equipment which are important for safety. These parts are marked by

in the Schematic Diagrams, Circuit Board Diagrams, Exploded Views and Replacement Parts List. It is essential that these cirtical parts should be replaced with manufacturer's specified parts to prevent shock, fire or other hazards. Do not modify the original design without permission of manufacturer.

IMPORTANT INFORMATION ABOUT LEAD FREE, (PbF), SOLDERING

1 Safety Precautions

1.1.For Service Technicians

•Repair service shall be provided in accordance with repair technology information such as service manual so as to prevent fires, injury or electric shock, which can be caused by improper repair work.

1.When repair services are provided, neither the products nor their parts or members shall be remodeled.

2.If a lead wire assembly is supplied as a repair part, the lead wire assembly shall be replaced.

3.FASTON terminals shall be plugged straight in and unplugged straight out.

•ICs and LSIs are vulnerable to static electricity.

When repairing, the following precautions will help prevent recurring malfunctions.

1.Cover plastic parts boxes with aluminum foil.

2.Ground the soldering irons.

3.Use a conductive mat on worktable.

4.Do not grasp IC or LSI pins with bare fingers.

2 Warning

2.1.Battery Caution

1.Danger of explosion if battery is incorrectly replaced.

2.Replace only with the same or equivalent type recommended by the manufacturer.

3.Dispose of used batteries according to the manufacture’s Instructions.

2.2.About Lead Free Solder (PbF: Pb free)

Note:

In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that contains lead.

We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn), Silver (Ag), and Copper (Cu).

This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair work we suggest using the same type of solder.

Caution

•PbF solder has a melting point that is 50°F ~70°F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron with temperature control and adjust it to 700°F ± 20°F (370°C ± 10°C).

•Exercise care while using higher temperature soldering irons.: Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB.

•PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C).

•When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the opposite side (See the figure below).

2.2.1.Suggested PbF Solder

There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper (Sn+Ag+Cu), you can also use Tin and Copper (Sn+Cu) or Tin, Zinc, and Bismuth (Sn+Zn+Bi). Please check the manufacturer’s specific instructions for the melting points of their products and any precautions for using their product with other materials. The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3 mm, 0.6 mm and 1.0 mm.

0.3 mm X 100 g	0.6 mm X 100 g	1.0 mm X 100 g

2.3.Discarding of P.C. Board

When discarding P. C. Board, delete all personal information such as telephone directory and caller list or scrap P. C. Board.

4.2.3.Telephone Line Interface

<Function>

•Bell signal detection

•Clip signal detection

•ON/OFF hook circuit

•Audio circuits

Bell & Clip (: Calling Line Identification Presentation: Caller ID) signal detection:

In the standby mode, Q3 is open to cut the DC loop current and decrease the ring load.

When ring voltage appears at the L1T and L1R leads (when the telephone rings), the signal is transferred as follows;

•A → C26 → R33 → R50, C70 → R16, R30 → R200 → LINEN [BELL & CLIP]

•B → C27 → R34 → R51, C71 → R19, R31 → R201 → LINEP [BELL & CLIP]

ON/OFF hook circuit:

In the standby mode, Q3 is open, and connected as to cut the DC loop current and to cut the voice signal. The unit is consequently in an off-hook condition.

When IC3 detects a ring signal or press the TALK Key onto the handset, Q2 turns on and then Q3 turns on, thus providing an offhook condition (active DC current flow through the circuit) and the following signal flow is for the loop current.

• A → D2 → Q3 → Q1 → R9 → R10 → D2→ B [OFF HOOK]

Audio circuits:

Refer to Signal Route (P.12).

4.2.4.Transmitter/Receiver

Base Unit and Handset mainly consist of RF Module and DECT BBIC.

Base Unit and Handset transmit/receive voice signal and data signal through the antenna on carrier frequency.

Signal Path:

*Refer to Signal Route (P.12).

4.2.4.1.Transmitter Block

The voice signal input from the TEL LINE interface goes to DECT BBIC (IC3) as shown in Block Diagram (Base Unit) (P.7) The voice signal passes through the analog part of IC3 where it is amplified and converted to a digital audio stream signal. The burst switch controller processes this stream performing encryption and scrambling, adding the various other fields to produce the GAP (Generic Access Profile) standard DECT frame, assigning to a time slot and channel etc.

In IC3, the carrier frequency is changing, and frequency modulated RF signal is generated and amplified, and radiated from antenna. Handset detects the voice signal or data signal in the circuit same as the following explanation of Receiver Block.

4.2.4.2.Receiver Block

The signal of 1.9 GHz band (1.881792 GHz ~ 1.897344 GHz) which is input from antenna is input to IC3 as shown in Block Diagram (Base Unit) (P.7).

In IC3, the signal of 1.9 GHz band is demodulated, and goes to IC2 as GAP (Generic Access Profile) standard DECT frames. It passes through the decoding section burst switch controller where it separates out the frame information and performs deencryption and de-scrambling as required. It then goes to the DSP section where it is turned back into analog audio. This is amplified by the analog front end, and goes to the TEL LINE Interface.

4.2.5.Pulse Dialling

During pulse dialing the hookswitch (Q3, Q4) is used to generate the pulses using the HOOK control signal, which is set high during pulses. To force the line impedance low during the “pause” intervals between dial pulses, the PULSE_DIAL signal turns on Q2.

4.4.Circuit Operation (Handset)

4.4.1.Outline

Handset consists of the following ICs as shown in Block Diagram (Handset) (P.10).

•DECT BBIC (Base Band IC): IC103

-All data signals (forming/analyzing ACK or CMD signal)

-All interfaces (ex: Key, Detector Circuit, Charge, DC/DC Converter, EEPROM, LCD)

-PLL Oscillator

-Detector

-Compress/Expander

-Amplifier for transmission and reception

•EEPROM: IC102

-Temporary operating parameters

4.4.2.Power Supply Circuit/Reset Circuit

Circuit Operation:

When power on the Handset, the voltage is as follows;

B A T T E R Y ( 2 . 2 V ~2 . 6 V ) D 1 0 7 IC103 - V D D B A T IC 1 0 3 - S D R V R 1 0 7

L 1 0 3 I C 1 0 13 . 3 V

The Reset signal generates R121, C186 and 2.6V.

4.4.3.Charge Circuit

Circuit Operation:

When charging the handset on the Base Unit, the charge current is as follows;

DC+ → F1 → R39 → CHARGE+ (Base) → CHARGE+ (Handset) → Q101 → L104 → BATTERY+... Battery...

BATTERY- → R102 → GND → CHARGE- (Handset)→ CHARGE- (Base) → GND → DC- (GND) In this way, the BBIC on Handset detects the fact that the battery is charged.

The charge current is controlled by switching Q101 of Handset. Refer to Fig.101 in Power Supply Circuit (P.8).

4.4.4.Battery Low/Power Down Detector

Circuit Operation:

“Battery Low” and “Power Down” are detected by BBIC which check the voltage from battery. The detected voltage is as follows;

•Battery Low

Battery voltage: V (Batt) < 2.20V

The BBIC detects this level and “” is displayed on LCD and “battery alarm” starts ringing.

•Power Down

Battery voltage: V (Batt) < 2.05V

The BBIC detects this level and power down.
