Audio Section

V202, R201 and R202 generates +5VA audio d.c. voltage. V202 is the micro­phone voltage regulator. N200 is the mic. amplifier. N200 is the differential am­plifier wich eliminates disturbancies generated in curly cable ground wire resis­tor. N200 has same function in XEAR line. R235 and C231 are low pass filter wich eliminates noise. N300 is speaker power amplifier. R302, R303 and C303 stabilicies the power amplifier in high frequencies.

Circuit Description

Input Circuit
C1 is the EMI capacitor. F1 is the foil fuse. L1 and L2 are EMI suppressor chokes. V1 is the voltage suppressor diode (zener type).
Power Control Logic
Input power is connected to d.c. connector X100. Power is connected to audio devices thru P–FET V410 and 10 V regulator N100 (VBSW). This power is con­nected when M2BUS signal goes high. Also XEAR signal can connect power on 5 sec by grounding it with 100 k resistor, wich is located inside the phone. Same 5 sec power on time occurs also, when MBUS and XEAR are low and input power occurs to d.c. connector. C11 acts like a timing capacitor.
Switched Mode Power Supply
The WBSV voltage generated by N100 starts the switched mode power supply (SMPS) by starting reference regulator N402. V409 leads the initial current to totally empty battery. V410 is an constant current source wich sets the voltage value of R408. Same voltage occurs over the current shunt resistor R410, when the SMPS is working. N401a is an pulse width modulator. N401b with R407,C408 and V408 generates a minimum pulse width of SMPS. R405 and R406 are input and output voltage correction resistors. V412 shutdowns the SMPS when VB input voltage goes over 17 V. V407 limits the comparator pow­er supply VCC. V408 and V406 limits the comparator output voltage. V403 and C403 consist an bootstrap circuit, wich act like voltage doubler. V400 is the SMPS switch. L401 (L402), R403 and C405 are EMI suppression components. L400 is the main SMPS inductor. V411 limits the maximum output voltage.

Technical Documentation PHF–1
The phone is connected to the unit by a system connector. There are also con­nectors for external power source, for standard HF–microphone and for exter­nal antenna(s).
The Compact Handsfree Holder consists of speaker– and microphone– amplifi­ers, power on/off –logic, HF–speaker muting and the constant current switch­ing regulator for charging the phone battery. The unit has an inbuilt HF–speak­er and an external HF–microphone but the actual handsfree function is generated in the phone.
MPHF1 mechanic consists of the front and rear covers, the holder cover,
The screws, type label, system–cable with RF–cable(s).

Modes of Operation

Power off: The DH3 module does not receive supply voltage
to the d.c. connector (X100 so there aro not any voltages on the module.
Standby: The module receives supply voltage to the d.c.
connector but the telephone has put the M2BUS line (X400) down (”0”–state) because the phone is off and the battery is fully charged. The switching regulator in off and there is not any supply voltage for the audio.
Power on/ The M2BUS –line is high (”1”–state) so the switching speaker off: regulator supplies charging current to the phone. The
supply voltage for the audio is on but the PHFS –line (X400) is down (”0”–state) so the HF–speaker is muted.
Power on/ The switching regulator supplies charging current to speaker on the phone. The supply voltage for the audio is on and
the PHFS–line is high (”1”–state) so the HF–speaker is on.

Compact HF Holder PHF–1
Introduction
The PHF–1 is compact handsfree holder for the second generation digital handportable telephones and they provide possibility to use handsfree opera­tion where the fixed handsfree configuration is not possible. They have also phone battery charging function.
Technical DocumentationPHF–1

Technical Summary

The installation to the car is possible by four separate methods. Using the sep­arate mounting plate, strechable bands, adhesive tape, or ”velco straps”.
The configuration allows both the handsfree– and the handset–use of the phone. The handset–use is possible with the curly system cable which includes also the antenna cable(s). The separation of the HF– and hs–mode is made by the hook–switch in the holder .
