Note - CP+/CM-: Refer to Base Unit Reference Drawing. - TP-VBAT: Refer to Handset Reference Drawing. 8.5. Check Link (*1) Refer to "Finding out the Defective Unit”. 8.6. Check the RF Unit 8.6.1. Finding out the Defective Unit Prepare HS JIG (Handset-jig) and BS JIG (Base Unit-jig). Place the HS JIG on the cradle of the base unit for checking, then confirm that they are linked.
Page 26
8.6.2.1. Handset-jig (HS JIG) for Base Unit The handset unit jig also uses two modes: TEST SUPER LOW mode and NORMAL POWER mode. These modes alternate when the handset CLEAR button is pressed: (1) NORMAL POWER mode (Stand-By). In this mode the LCD will remain blank. (2) TEST SUPER LOW mode.
Page 27
modes alternate when the base unit LOCATOR button is pressed: (1) NORMAL POWER mode, TEST SUPER LOW (red) is OFF. This test simulates the handset is at normal/close distance. The base unit is in NORMAL POWER mode right after the AC adapter has been inserted.

(*1) See Handset Reference Drawing. (*2) Special check method for Handset individually. 9.3. Adjustment X101 IN case of SS system, Carrier signal frequency directly can not be measured by Frequency counter, because sending signal is spread by PN code. So, the confirmation and adjustment is made under the Continuous Send mode of TEST MODE. Adjust the TX carrier (CW) frequency on the RF unit.
9.5. Handset Reference Drawing 9.6. FREQUENCY TABLE 10. DESCRIPTION 10.1. Frequency The frequency range of 906.00 MHz ~ 923.25 MHz is used. Transmitting and receiving channel between base unit and handset is same frequency. Refer to the Frequency Table. 10.2. Time Division Duplex (TDD) operation Transmission/reception between the base unit and handset is performed by time-sharing as shown in Fig.
10.2.1. TDD Frame Format The TDD frame is 2mS in length, and is composed of two symmetrical 960 S TX and RX subframes. Each subframe contains 96 bits of 10 S duration, with 40 S guard times between both TX and RX subframes. Each subframe consists of the following four fields: - A 16-bit Preamble field - An 8-bit Data Channel field...
10.4. Signal Flowchart in the Whole System Reception CN101 (LINE 1/2) or CN201 (LINE 2) of the base unit is connected to the TEL line, and the signal is input through the bridge diode D101 (LINE 1), D201 (LINE 2). While talking the relay (Q101 for LINE 1, Q201 for LINE 2) is turned ON and amplified at the amplifiers Q162 and Q164 (LINE 1), IC250, IC251, Q264 (LINE 2), then led to DSP (IC501).

13.3. Power Supply Circuit Function: Power from the AC adaptor passes through a regulating block consisting of IC301. Circuit Operation: IC301 is a regulated power supply. The voltage at point A is regulated to 4.0V by IC301. The voltage at point B is dropped by D306 and D310 to 3.3V. The voltage at point C is regulated to 5.5V by IC341.

13.4. DTMF Signal When the DTMF data from the Handset is received, the DTMF signal is output from pin 41 (LINE 1), pin 39 (LINE 2) of IC501 and sent to the line through Q161 (LINE 1), Q261 (LINE 2). 13.5.

The caller ID is a chargeable ID which the user of a telephone circuit obtains by entering a contract with the telephone company to utilize a caller ID service. For this reason, the operation of this circuit assumes that a caller ID service contract has been entered for the circuit being used.
Page 52
Call Waiting Calling Identity Delivery on Call Waiting (CIDCW) is a CLASS service that allows a customer, while off-hook on an existing call, to receive information about a calling party on a waited call. The transmission of the calling information takes place almost immediately after the customer is alerted to the new call so he/she can use this information to decide whether to take the new call.
Page 53
13.8. Parallel Connection Detection Circuit Function: In order to disable call waiting and stutter tone functions when using telephones connected in parallel, it is necessary to have a circuit that judges whether a telephone connected in parallel is in use or not. This circuit determines whether the telephone connected in parallel is on hook or off hook by detecting changes in the T/R voltage.
Page 54
When off hook Q141, Q142 (LINE 1), Q241, Q242 (LINE 2) is OFF, the voltage is monitored pin 50 (LINE 1) and 43 (LINE 2) of IC501; the presence/absence of a parallel connection is determined when the voltage changes by 0.2 V or more. 13.8.1.
the functions of speech compression. The DSP system is fully controlled by a host processor IC501. The host processor provides activation and control of all that functions, such as Tone detecting and Line monitoring. The DSP system comprises of following. —...

13.10.2. LINE 2 Circuit Operation: ON HOOK Q201 is open, Q201 is connected as to cut the DC loop current and to cut the voice signal. The unit is consequently in an on-hook condition. SPECIFICATIONS In the on-hook state (idle), the current flows between the telephone line and the unit is as follows PO201 L201 C203...

13.11. Intercom Mode 1. When the base unit LOCATOR/INTERCOM button is pressed, a call monitor signal (intercom sound) is output from pins 35 and 37 of IC501. Thus a monitor tone is heard from the speaker. 2. At the same time, flashing of the IN USE/CHARGE (LED501) is obtained from pin 101 of IC501.
15.1. Power Supply Circuit Voltage is supplied separately to each block. 15.2. Charge Circuit Ni-Cd battery is connected to CN202. When the handset is put on the cradle of the base unit, the power is supplied from CHARGE1 and CHARGE2 terminals to charge the battery. Q207 detects the voltage of CHARGE1 and CHARGE2 terminals, then the handset makes ID code setting with the base unit.
15.4. Sending Signal The voice signal from the microphone input to pin 42 (CIDIP) and pin 41(CIDIN) of IC201 (DSP). CN203 is the headphone jack. When the headphone is connected, the Q206 detect it. The input from the microphone of the handset (CIDIN, CIDIP) is cut and the microphone signal from the headphone is input to pin 47 of IC201 (HMIN).
15.5. Reception Signal Circuit The received signal from the base unit is output from pins 33 (SPN) and 32 (SPP) of IC201 (DSP) as the voice signal. SPN is the inverse output of SPP, and the speaker is driven by SPN and SPP.
