User Interface Features

HF desktop charger is designed for charging the handportable phone and the
spare battery. It provides also handsfree function when the phone is on the
charger. The unit has inbuilt HF speaker and HF microphone but the actual
handsfree function is generated in the phone. There are also three operating
buttons. The front one is for muting the HF microphone, the middle one is for
the voice mail listening and the rear one is for the spare battery discharging.

Charging takes place at a battery temperatures of 5...45 Centigrade. Charge
control of the phone is done with phone microprocessor and charge control of
extra battery is done with separate microprocessor located in a desktop stand.
Phone is always charged first, then extra battery.

A battery gives better capacity if it is occasionally discharged completely. User
can do this by using the ‘deep discharge‘ –feature of CHH–8P. This feature is
provided only extra battery slot and pressing the ‘discharge‘ –button. The extra
battery will then automatically be discharged and charged to full. If this button is
pressed twice then the discharge function is cancelled.

NHB–3

HF Desktop Charger CHH–8P

Charging Indication

Charge is indicated with two dual–colors led‘s, one for the phone and one for
the extra battery pack. The liquid–crystal display of the phone also contains a
three–bar battery display.

Leds are dimmed when there is no phone or extra battery connected.

Right led for handportable:
Red phone led indicates a fast charge mode of the phone battery.
Green phone led indicates that the phone battery is full and tricle charge mode

is on.

Left led for spare battery:
Red spare battery led indicates that the battery is not full; either there is a fast

charge mode active or charging is disabled due to a battery temperature or to
fast charge mode of the phone.

Green spare battery led indicates that the battery is full.
Flashing red spare battery led indicates that a discharge cycle is activated.

Charge States and Charge Control

Charge current for the phone is supplied through a series switch transistor in
the phone. When this transistor is on the charger is supplying a constant
current to the phone. This is the rapid charge mode.

When the transistor is off no current is supplied to the phone and the charger is
in the constant voltage mode.

Original 26/97 Page 5

PAMS
Technical Documentation

Having been charged up in the rapid charge mode, the battery is kept in full
charge using pulsed charging, i.e. switching power alternately on and off at a
variable duty cycle and a frequency of a few Hz.

The desktop charger is also provided with control logic for spare battery charg­ing, which is allowed when no phone is connected or when the phone is in the
pulsed charge mode.

Instructions for Use

Plug in the ACS–6 AC power supply to the mains outlet. Connect the cord from
ACS–6 to the dc connector at the rear of the CHH–8 HF desktop charger.

Charging the Phone Battery

Place the phone into the recess in the charger. The right–hand indicator at the
front edge of the charger shows the charge of the phone battery. The red led is
lit during quick charging, and once the phone battery has reached full charge,
the green led alights, showing that only trickle charging is on.

NHB–3

HF Desktop Charger CHH–8P

When the phone is powered, the charge can be read from three indicator bars
appearing on the phone display. During the quick charging phase, each bar is lit
alternately for one second. Once the battery is fully charged all three bars are
lit. If the charger indicator is not lit when the phone is on the charger, ensure
that the phone is properly in place and that the power supply is correctly
plugged to the charger and to the wall outlet.

The battery will not accept charge if its temperature is below +5 C or above
+45 C.

Charging the Extra Battery

Place the extra battery into the recess in the charger. The left hand indicator of
the charger shows battery charge. During quick charging, the red indicator is lit
and once the battery has reached full charge, the green indicator alights show­ing trickle charging. If the phone and the extra battery are on the charger at the
same time the phone battery is charged first, followed by charging of the extra
battery.

If the charger indicator is off when the extra battery is installed on the charger,
ensure that the extra battery is properly in place and that the power supply is
correctly plugged in to the charger and to the wall outlet.

The battery will not accept charge at a temperature of below +5 C or above
+45 C.

Technical Documentation

Deep Discharging of the Extra Battery

In the interests of best possible battery efficiency, it is recommended that the
battery be deep discharged once a week or so.

To start the deep discharge function, press once the discharge key at the rear
of the charger, whereupon the red indicator showing extra battery charging
starts to flash. Once the battery has been discharged, the charger will automati­cally start charging it. Should you wish to interrupt discharging, press the dis­charge key again. The indicator ceases to flash and the charger will resume
battery charging. It is not recommendable to deep discharge a fully charged
battery.

Handsfree Function

When installed in the charging stand, the phone is always in the handsfree
mode of operation. The internal HF speaker and HF microphone are then
activated for the call. It is also possible to turn the phone into HF mode and off
while a call is going on. This is done by removing the phone or placing it on the
charger.

NHB–3

HF Desktop Charger CHH–8P

HF speaker volume is adjusted at the phone volume key, and an outgoing call
can be muted by presssing at the mute key on the front edge of the charger.
The muted state is indicated by the message ”MUTED” on the phone display.
Pressing the key once more cancels muting, shown by the text ”UNMUTED”
which appears on the display for a moment.

Using the Voice Mail

The voice–mail key in the middle of the charger is for calling one’s voice mail­box in the network switching centre and listening to voice messages. When
calling the voice mailbox, the first press on the key makes the call to the
mailbox and the second ends the call.

The Data Connection

The charger contains a 10–pin modular connector for data accessories
(e.g. PCMCIA card).

Modes of Operation

Power off mode: If the unit doesn’t receive power supply to the d.c.

connector there isn’t any voltage on the module.

Standby mode: The unit receives supply voltage to the d.c. connector.

The processor is running but because there isn’t any
phone or spare battery on the cradle, the charger is off
and the audio functions are inactive.

Active mode: The telephone or spare battery is on the cradle so the

charging functions are active. Normally the handsfree
speaker is muted. During a call and during the key
beeps or alarming tones the speaker and corresponding
audio switches are open.

Functional Description

The DC3 module electronics consists of the following functional blocks:
– Supply voltages
– Control logic
– Battery charging
– Spare battery discharging
– Watchdog circuit
– Microphone amplifier and corresponding switches
– Speaker amplifier and corresponding switches

Supply Voltages

The supply voltage +VI (11.0 V– 20.0 V) for the DC3– and DC4–modules is
taken from the power supply connector X100 connected to the Power Supply
ACS–6.

NHB–3

HF Desktop Charger CHH–8P

The battery charging voltage +VCC (10.0 V – 13.0 V) is connected to the phone
or to the spare battery.

+VE voltage (5.0 V) is generated by the regulator N150 to charge totally empty
battery to the +5.0 V level.

+VA voltage (10.0 V) is the supply for the analog parts. From that voltage are
generated also analog voltages +VAN (5.0 V) and +VAS (10.0 V). Reference
voltage +VREF (2.75 V) for the analog is made by the N430–A from the +VAN
voltage.

+5V voltage is the supply for digital parts, generated by the regulator N103.

Control Logic

The phone battery and spare battery charging indication, spare battery
charging and discharging, audio connections and activation of voice mail are
controlled by processor D300. It is a single–chip type controller incorporating
RAM, ROM, A/D converter and a multifunction timer/counter.

The processor communicates with the handphone via the M2BUS. The M2BUS
interface comprises transistors V200, V201 and corresponding resistors.

Watchdog Circuits

Under normal operation the processor is pulsating the WTCHDOG–line to
reseting the ”power off”– and ”software reset”–watchdogs.
If the processor doesn’t run correctly, then the transistor V210 turns off and the
”Software reset”–watchdog V211 gives reset pulse through C211 to the RE­SET–line. If after this reseting the processor still runs incorrectly, then the ”Pow­er off”–watchdog (V212, V213) turns off the +5 V regulator N103.

Battery Charging

Charging current for the phone battery is fed in via transistor V311, which is
always on when the phone is connected to the system connector X701 on the
DC4 module. Phone battery charging state is indicated by the red (V344, V345)
and green (V333) leds. Because the phone and the spare battery cannot be
charged at the same time the charging current of the phone must be detected
and this is done with the current mirror V321 and corresponding resistors.

Charging current for the spare battery is fed in via switching transistor V221
and schotky diode V220. The transistor is controlled by the processor (SPARE
CHARGE –line). When the phone battery is not charged and it is allowed to
charge the spare battery, the transistor is on and a constant current is supplied
to the battery (the red led V331 lits). In the pulsed charging mode the charging
current is adjusted by pulsating this charge current (the green led V330 lits).

NHB–3

HF Desktop Charger CHH–8P

Spare battery voltage and ∆V–voltage are determined by reading the VBAT line
state. Voltages are measured through resistor divider R250 / R251 and the am­plifier N250–B.

Spare battery size is determined by reading the BSI line state. This is pulled to
+5 V reference voltage by R243. In the battery pack a ”size” resistor is con­nected between BSI and GND.

Temperature is measured over the BTEMP line. This line is pulled to +5 V
reference voltage by R242. In the battery pack an NTC resistor is connected
between BTEMP and GND.

Spare Battery Discharging

The desktop charger is also provided with a discharge function. This is
activated by pressing the discharge button S300. Resistors R230–R237
determines the discharge current which is fed through switching transistor V230
controlled by the processor. The discharging is indicated by blinking of the red
led V331. The battery is discharged to +5 V and thereafter charged normally to
full.

Microphone Amplifier and Corresponding Switches

Transistor amplifier circuit V420 and corresponding resistors and capasitors
supplies bias current for microphone. Operational amplifier N430–B is used to
amplify the microphone signal to the handphone. The gain of this amplifier is
about 40 dB. The HF microphone signal is fed to the phone through the analog
switches D400–B and D400–C. The microphone signal XMIC from the Data Ac­cessory (X510) is fed to the phone through the switches D400–A and D400–C.
The supply voltage for the amplifier and the analog switched are taken from the
+VAN regulator N102. The +VREF reference voltage (≅ +2.75 V) is made with
the N430–A from the +VAN analog voltage ( ≅ +5.0 V) .

Speaker Amplifier and Corresponding Swithes

XEAR signal from the phone is fed to the HF speaker through the analog
swithes D410–C and D410–B. The signal is amplified about 17 dB with the
resistors R460, R461 and the amplifier N460. The speaker can be muted with
the MUTE–signal controlled by the prosessor.

NHB–3

XEAR signal from the phone can be fed to the Data Accessory (X510) through
the analog switches D410–C and D410–A.

The supply voltage +VAS (≅ +9.7 V) for the speaker amplifier is taken through
the transistor V341, controlled by the processor, from the +VA regulator N100
(≅+10.0 V).
